Mainly a great day today!

 Surface chart and radar.

 

Most of the region suffered with the Canadian Wildfire smoke yesterday. But today the northwest winds have shifted enough to push the smoke out of Northern Pennsylvania, New York State and New England.  So today these areas will see blue skies and plenty of Sun. Radar is showing the entire region is dry, that should remain the cast today, but I can’t rule out an isolated rain shower or two. Looking at the satellite, we can see the smoke is still sitting over western Pennsylvania and down into the Middle Atlantic.  Looking at the Air Quality Map, we can see that the purple color that indicated where the very unhealthy air quality conditions are located.  Behind the front temperatures are seasonal and humidity levels are low.

Enjoy the smoke free air for now, because the smoke and hazy skies are going to start to return late this afternoon and tonight.  As that frontal boundary turns into a warm front and starts to move back to the north. Looking at tomorrow smoke forecast map, we can see the heavy smoke is back over much of the region by tomorrow afternoon.

As those warm front lifts north warmer temperatures and much higher humidity is going to move north with it. Ahead of the front scattered showers and storms will be likely. Then later in the day a cold front will come through and slam into the warmer and humid airmass. Setting the stage for more in the way of widespread rain showers and scattered thunderstorms. Some of these thunderstorms will be strong to severe. Winds aloft could mix down to the surface, creating the risk for damaging winds, with all the humidity in the air, heavy downpours are also very possible. There will also be the risk for some hail and frequent vivid lightning. The tornado risk is low, but not zero. The cold front should be clearing the region Sunday morning, so there could be some lingering rain showers and thunderstorms.

Behind the cold front Sunday and Monday conditions will be seasonal with low to moderate humidity. The entire region should be mainly dry.  The high pressure will shift east on Tuesday, as a warm front lifts in ahead of a cold front.  We will see if tropical moisture can work into parts of our region. Then for later Tuesday and Wednesday that cold front will lift through bringing waves of widespread rain and thunderstorms, some of these thunderstorms could be strong to severe.  Thursday and Friday will see high pressure move in overhead, providing a mostly dry time with temperatures at seasonal to below average levels.

The trough axis is going to shift west and east over the next 7 to 10 days, which means the smoke will be impacting parts of our region from time to time.

 

The Tropics

We have that stationary front with an area of low pressure starting to develop off the west coast of Florida. The NHC has the area still at a 20% chance for development. For us the only thing we will have to watch is tropical moisture trying to drift north and interact with a cold front early next week.

That other wave in the eastern Atlantic south of the Capo Virdie Islands is still at a 10% chance for development. But conditions to its west are very hostile and it shouldn’t develop into anything.

Have a great day and have an enjoyable and safe weekend!
