Big Bada Boom

 

I’ve been asked about the large boom that occurred earlier today over eastern New England. So, I thought many of y’all likely had the same question….so here is my take on what is going on.

 Over the last few days, there have been several reports of sonic booms over the Eastern Seaboard. Two days ago in the late Thursday afternoon, there was a loud boom over South Carolina, that resulted in the ground shaking, across a large area.  Sonic booms are caused by a shock wave when an object passes the speed of sound, most sonic booms are caused by aircraft. The U.S. Geological Survey said this wasn’t the result of an earthquake and was caused by something in the atmosphere. Over South Carolina there were no eyewitness reports of a fireball and there were no satellite detections of a meteor at that time over the area. While it is still possible that this was caused by a large meteor, and no one saw it. It is more than likely the result of a military jet breaking the sound barrier.

To be considered a fireball, the meteor must be at least as bright as Venus. This exceptional brightness is usually a result of a large meteoroid - possibly a few meters in diameter upon entering Earth's atmosphere. When a large meteoroid explodes in the Earth’s atmosphere it is called a bolide.

This afternoon there was another sonic boom this one was over eastern Massachusetts. This was heard and felt across parts of New Hampshire, Massachusetts, Connecticut and Rhode Island. I heard of a report of a loud boom over Maine, but I don’t know if that is connected. Unlike the boom over South Carolina, this one was observed by the GOES 19 lightning detection mapper. Here is an image from the Satellite at the time of the sonic boom. The bright flash seen on the image wasn’t associated with the nor’easter off the Coast.

 

There were also reports of people seeing the meteor streak over parts of New York State.  So, the sonic boom that many heard was the result of a large meteoroid entering the Earth’s atmosphere.

There have been reports of sonic booms over other parts of the U.S. the last few days as well. I do know there were several small asteroids that made close approaches. It is possible that all of this is associated with other rocks from the same cluster.    

Saturday the last weekend of May

The surface chart shows that area of low pressure over New England back into New York State dropping south and east. Satellite is showing a lot of spin.  

This is going to end up sitting south and east of New England.  This is going to make for very cool and gusty conditions. Radar is showing the rain over central and Southern New England extending into the Southern and Mid-Hudson Valley.  The snow in the high elevations of Vermont and New Hampshire is going to continue for today.  For much of New York State, Pennsylvania, Maryland, Delaware and New Jersey it should be mainly dry with lower humidity there will only be a chance for some isolated showers. 

The surface chart is also showing the Surface low developing south and east of Cape Cod. This is going to continue to develop and intensify as it pushes east. This is going to end-up becoming a little nor’easter for a short time. Those across central and southern New England and along the north shore of Long Island will see the highest gust of generally around 40-50 mph with locally higher gust.  This will continue to pull that cooler air into New England and Eastern New York State where temperatures will be well below average. The rest of the region won’t be quite as cool with temperatures running slightly to below average. 

As all of this pulls away, high pressure will push in overhead tomorrow (Last day of Meteorological Sring). Then we’re going to see a trough drop into the region for Sunday night into Monday, bringing back unsettled weather, with scattered rain showers. Sunday will see temperatures start to moderate, by Monday our temperatures should return to seasonal levels. The trough will be breaking down on Tuesday, allowing for the chance for isolated to scattered showers to continue. For the second half of next week, high pressure will build in overhead. We should end up with generally dry conditions will temperatures becoming milder. Then on Saturday an area of low pressure will be dragging a cold front through the region. Bringing back the threat for rain showers and cooler conditions. 

Have a great weekend!

It cools off for the rest of the week.

 

The current surface chart and radar

 

 

We’re going to see the low pressure over western Quebec dive southward into northern New England. This will allow several little troughs to drop down into the region.  This will also bring another cold front, heavier rain that will be steady at times into parts of our region, this will be especially true across northeast New York State and northern Vermont and New Hampshire as well as southern and western parts of Maine.

For the rest of Maine, most of New York state and Connecticut, Most of Massachusetts and Rhode Island. the region will see isolated spotty showers. Away from northern New England many will stay dry. Across Pennsylvania Maryland Delaware and New Jersey, it is looking dry to mostly dry with partly to mostly sunny skies. All in all, this weekend is going to be much nicer than the Memorial Day weekend, for most of us.

This is going to pull down well below average temperatures for the Weekend. Making it feel more like early April than the end of May. 

The temperatures will likely be cold enough in the upper levels that we could see some snow or mixed precipitation in the higher peaks of the Adirondacks, the Green Mountains, and the White Mountains; this will impact areas above 3,500 feet with a few inches of wet snow falling Friday Night into Saturday morning as well below average cold air moves in.

Over the weekend we’re going to have that low pressure moves away from the region, but we’re going to have an upper-level low sitting over the Gulf of Maine, helping keep it a bit unsettled.

Monday we will still be dealing with that trough, keeping it a bit unsettled with the chance for isolated to scattered rain showers. Tuesday into Wednesday we will see the trough linger, keeping the threat for isolated showers around. The first part of next week will be a little milder than the weekend, but it will still feel coolish.  High pressure finely moves back in on Thursday with sunny skies, but it will still be a bit cool

 Drought conditions

 

 The U.S. Drought Monitor released earlier today showed drought and/or abnormally dry conditions improve across parts of New England and the Mid-Atlantic. Needed precipitation enhanced soil moisture, streamflow, and groundwater levels in parts of Maryland, and southern Pennsylvania. However, portions of southern New England continued to see diminished rainfall which resulted in expansion of the drought conditions. There were generally there wasn’t much change elsewhere in the Northeast. The U.S. Drought Monitor showed 3% of New York and New England in severe drought, 21% in moderate drought, and 22% as abnormally dry compared to 3%, 22%, and 23%, respectively, last week.

 

Return of the heat and a look at the tropics

The surface chart and radar

 

 

We can see high pressure building south, providing lots of sunshine and above average temperatures. But we do have a frontal boundary hanging out over the Delmarva.  Along that boundary, we do have scattered rain showers. This boundary is going to be bouncing around for much of this week, keeping things unsettled. We also have a weather pattern sitting over North America called an Omega Block.   It’s called this because the jet stream from west to east sets up into what looks like the Greek letter omega. The block causes the typical east-west flow of the jet stream systems to move slowly around it for several days, leading to the day after day weather systems hanging around across the country. Here’s a look at the 500 mb anomaly chart from tropical tidbits.  I’ve drawn on the chart the omega shape in the flow.

 

What this means for us here in our region; is we’re going to see a series of shortwave disturbances drop out of Canada and move across the Northeast. 

This is going to help the frontal boundary keep things very unsettled.  

Tomorrow will feature increasing clouds and scattered rain showers as a backdoor cold front slide through later in the day out of Canada.  This will be the first of two surges of Canadian air; this will make for Thursday into Friday to cool back off with temperatures becoming seasonal for this time of year. With the trough isolated to scattered pesky rain showers will be an issue. The rain will be a bigger issue for southern Pennsylvania and the Mid-Atlantic, but even here the showers should be light. Friday during the day won’t be too bad as high pressure will be pushing in. Then for later Friday and Saturday a more robust system with a cold front will bring rain showers to the region. It is also going to produce a stronger surge of cool air into the Northeast over the weekend. Along with the rain will be the chance for wet snowflakes mixing across the   higher peaks of the Adirondacks, Greens and White Mountains Friday night into Saturday. Some interior valleys could also see some frost. But that should be isolated.

Sunday will see high pressure return providing the nicest day of the weekend, with temperatures turning a bit milder. Then on Monday we will see another of low pressure centered to our south bring back the rain showers into the region. On Tuesday this area of low pressure will be sliding off the Middle Atlantic Coast and will be intensifying. This will keep interior parts of the region unsettled, with more in the way of widespread rain showers over the northern Middle Atlantic and Southern New England.

 The tropics

We do have a large area of rain out over the Central into eastern Gulf of America. But this won’t develop into anything tropical.

We have a front that is dropping south and east into the Gulf. This is going to interact with a disturbance currently in the Western Caribbean and tug it to the north. The SSTs in this area are warm enough to support tropical development. 

Image Credit Tropical Tidbits 

 This will track into the eastern Gulf toward Florida and southern Atlantic coast. The odds of this becoming Arthur are very low, but it is likely to bring some wind and locally heavy rain across parts of the Florida Peninsula for the final weekend of May into early June.

Didn’t feel like the “unofficial” start to summer

 

Memorial Day and quick post on the week ahead!

Surface Chart and Radar

Saturday and Sunday we’re cool and wet.  Over the holiday weekend 1-4 inches of rain fell across the region.

Today, we had a coolish start with lingering rain. But then drier air worked in, and we saw some afternoon clearing, allowing the day became nicer for most of us. But rain is lingering south of the Mason Dixon Line. Our temperatures during the day were still on the cool side of average.

Tuesday will be the nicest day of the week, sunny, very warm but breezy.  The day starts out a bit cool but looks dry for most of us with temperatures becoming above average. There is a chance for a few scattered showers in the Middle Atlantic closer to the frontal boundary. The warm and dry conditions will continue into Wednesday.  But after Tuesday we will be dealing with series of disturbances moving through. The first will be on Wednesday will see a cold front approach and will drop into the region out of Canada. With the frontal passage we will see variable clouds with isolated to scattered showers. The front will be moisture starved any showers should be quick and light. We’re going to see a regional cooldown with the frontal passage, with temperatures returning to seasonal along with lower humidity levels as well,

For Thursday and Friday, we will be dealing with a trough hanging around the region, keeping things seasonally cool and unsettled.  Later Friday into Saturday a more organized system will move into the region, with rain developing Friday night into Saturday.

This weekend will see the chance for a few showers, but Sunday will be the better of the two days. Then a better chance for rain moves in for Monday.

 

We must remember the heroes who made the ultimate sacrifice to ensure our freedoms. Their courage, sacrifice, and love for freedom can never be forgotten.

What about the first half of Summer?

 

I’m thinking of making changes to the way I report the near-term forecast. Due to the lack of views, I’m considering not posting so often on the weekly outlook. Based on the few views they get, I can only assume most of y’all don’t want them. But my seasonal and longer-term outlooks fare much better with many more views.  So, any feedback y’all what to give, would be great, as I do these post for all y’all.

This post is going to touch on El Nino and global SSTs along with the idea if of what the pattern is showing for the first half of Summer.

 This week is looking to continue this persistent overall coolish temperature profile.

 El Nino

 Probabilistic strength forecast

NOAA is getting increasingly bullish on the idea of a very strong El Nino

The Climate Prediction Center has us in an El Nino watch with SSTs in the equatorial Pacific at average to above average levels. Its sill looks very likely that they will soon declare an official El Nina in June or maybe July.

El Nino is highly likely to develop soon, with an 82% chance during May–July 2026. The CPC has a 96% chance it continues through winter 2026–27

Remember El Nino is characterized by a positive Relative Oleanonic Nino Index (RONI) greater than or equal to +0.5ºC. while La Nina: characterized by a negative RONI less than or equal to -0.5ºC.

Also, it’s important to remember that to be classified as a full-fledged El Nino or La Nina episode, these thresholds must be exceeded for a period of at least 5 consecutive overlapping 3-month seasons. The CPC considers El Nino or La Nina conditions to occur when the monthly relative Nino 3.4 departures meet or exceed +/- 0.5ºC along with consistent atmospheric features. These anomalies must also be forecasted to persist for 3 consecutive months.

 

Image Credit CPC

Looking at the current conditions in the four Nino zones. We can see that El Nino thresholds have been reached.

The westerly trade winds have increased in the eastern and central Pacific; this is another favorable El Nino signal. As they push the warm water due to the recent La Nina back to the east.

 

We can see that warm SST anomalies dominate the central/eastern Pacific. While cooler SST anomalies persist in the western Pacific.

 

Image Credit CPC

This is all showing upper‑ocean heat content is above average and is consistent with early El Nino development.

 

Image Credit CPC

Positive subsurface temperature anomalies have strengthened in the east‑central and eastern Pacific.

We can see those subsurface temperature anomalies are quickly heading for the surface, once they do, El Nino is going to take off like a racehorse.

Pacific SST Analysis

A large part of the Pacific is seeing above average SST.

This winter could see the subtropical jet become very active. If that is the case, there could be an increased risk for Coastal/Nor’easter type storms, making things more interesting for sure!

 

Atlantic SST Analysis

 

Image Credit Tropical Tidbits 

The Atlantic basin is warm with the Gulf, northern Caribbean, and western Atlantic seeing slightly to above average temperatures, the eastern tropical Atlantic into southern Caribbean is cooler than average closer to Africa, but that is going to continue to warm as we move through hurricane season.  This is why, my 2026 hurricane outlook is calling for average to above average activity this season, in spite of it being an El Nino year.

Link to my HurricaneOutlook.

 A sidebar

NOAA’s National Weather Service release their 2026 hurricane outlook a few days ago. They are predicting a below-normal hurricane season for the Atlantic basin

The agency is forecasting a total of 8-14 named storms (winds of 39 mph or higher). Of those, 3-6 are forecast to become hurricanes (winds of 74 mph or higher), including 1-3 major hurricanes (category 3, 4 or 5 with winds of 111 mph or higher). NOAA has a 70% confidence in these ranges. An average season has 14 named storms with seven hurricanes, including three major hurricanes.

NOAA’s and most of the other outlooks are showing a slightly less active season than I’m showing.

 

MJO

 

The MJO is looking to head into Phase 8 and Phase 1. This means we will likely see ridging develop over the Great Lakes as well as off the Eastern Seaboard. This is going to help us stay a bit coolish for the foreseeable future

The pattern

 

We’ve seen a very persistent Pattern during the entire Spring. This pattern looks to be extending into the Summer.

So, far this year we’ve seen a lot of ridging over the western U.S., with stubborn troughing over the eastern U.S.

 

The Bermuda High has been expanding west.  We’ve also had the western flow moving over and under that western ridge due to several shortwave troughs coming off the Pacific. This has resulted in all the rain and severe weather in parts of the Plains and Midwest.

 

June and July

Link to my SummerOutlook

In my Summer Outlook I said, this Spring into the Summer is likely to be overall cool. So far that is been the case. So far, I see nothing that is changing my thoughts. Here is what the EURO weekly is showing for June into July.  

 The next 7 days

 

Over the next couple of weeks

 

 

End of June into July

The model is supporting the idea that I’ve been talking about for the last few months.

That doesn’t mean we’re not going to see warm to hot days. It just means that overall temperatures will favor the cooler side. This will be based on the 30 year temperature anomalies for this time of year.

Conclusion

The Pacific is transitioning from ENSO‑neutral and quickly toward El Nino, with strong supporting signals in SSTs, subsurface heat profiles, and atmospheric patterns.

There is very high confidence that El Nino will dominate the 2026–27 winter, with potential for a strong event.

U.S. seasonal patterns are already showing early atmospheric shifts consistent with this transition.

Have a great rest of your Sunday

 It been hot over the last couple of days, but that is about to change

Surface Chart and Radar

It been hot over the last couple of days, but that is about to change

The surface chart and radar show the front advancing into the western part of the region with scattered rain showers associated with a trough ahead of it.

Temperatures are very warm to hot ahead of the front, with much cooler temperatures behind the front. Behind the front temperatures are running 20° F to near 40° F cooler than they are ahead of the front.  

As the front continues to advance, showers and thunderstorms are going to develop this afternoon and evening. Some of these storms could be strong to severe.

Images curtesy of Pivotal Weather

The biggest threat is going to be the possibility of damaging wind gust and moderate to perhaps large hail, with the higher humidity, heavy downpours and frequent vivid lightning will be possible. the risk for tornadoes is very low, but it's no zero. 

Tomorrow the cold front is going to slow even more and slowly sink through the Northern Middle Atlantic, with rain moving along it. Maryland, Delaware and southern New Jersey will be dealing with the rain the longest.  Tomorrow into Friday, high pressure will build in providing mainly dry conditions and much more sun.

We’re going to see a trough up over the Great Lakes move toward and into the Gulf of Maine. At the same time a warm front will push north and east, but it won’t get too far. This will set up a frontal boundary that will lead to unsettled conditions for the holiday weekend, with rain showers later Friday through the weekend into Monday.  Saturday and Sunday will be the wettest of the holiday weekend. But rain showers will linger into Monday.

 

That’s it…. No post for the next few days. 

Still Hot, but cooler weather is around the corner!

Today we’re all dealing with summer like heat along with some humidity.  Most of us will approach or set new record high temperatures. With the heat and humidity, it's going to feel like mid-summer.

 Look at the current surface chart and radar. 

We can see the warm front has pushed into Canada and northern Maine. The southern flow is driving in plenty of heat with most of y’all seeing temperatures in the upper 80’s into the upper 90’s. The higher dew points will make it feel warmer than that.  We can also see that strong cold front out west that is approaching our region. As this gets closer and starts to run into all this heat, out ahead of it we will see scattered showers and thunderstorms develop, some of these will be strong to severe. Here is a look at today’s convective outlook for today.

Images curtesy of Pivotal Weather 

This afternoon severe thunderstorms are likely to develop over northwest Pennsylvania, western and northern New York State. The biggest threat will be strong damaging winds and large hail. But with the humidity, frequent lightning and heavy downpours are also going to be a concern. The tornado risk is low, but a couple of isolated tornadoes are possible. The severe threat is going to extend into tonight as these move west to east. Way out ahead of the front there is a chance for some isolated showers and thunderstorms popping up this afternoon – a couple of these could be strong to severe.

We do have a few shortwave troughs that could be the focus for a few thunderstorms, this will be especially true for eastern Pennsylvania into Maryland Delaware New Jersey as well as New York City and Long Island. 

Wednesday 

As the cold front approaches, the Hudson Valley and eastern Pennsylvania, a few showers and maybe a few thunderstorms will be late morning and into the early afternoon. The as the front is dropping south and east into the lower Hudson Valley, southern New England, southwest Pennsylvania and the northern Middle Atlantic later Wednesday afternoon into the evening, scattered showers and thunderstorms are likely to flare up again with the potential of damaging wind gusts and large hail. 

End of the week and through the weekend.

 Behind the cold front, temperatures will turn noticeably cooler with the front pushing away Thursday is looking to be a mostly dry day with a mix of clouds and sun. The High pressure will continue into Friday. But on Friday we will be watching a frontal boundary to the south, try and push north, bringing a chance for rain showers into Maryland, Delaware, southern New Jersey and southern Pennsylvania. We also going to have a Canadian High Pressure centered up over the Canadian Maritimes and low pressure in the Gulf of Maine.  Between the high pressure and the slowly advancing frontal boundary, it’s going to keep us very cool and unsettled through the Memorial Day Weekend. For Memorial Day Monday, the boundary should be pushing north and west most of the region could see lingering showers, but up over New England scattered rain showers are likely. 

That’s it
