The ridge is starting to break down. Looking at the 500 mb height anomaly courtesy of tropical tidbits. We can see it's not as extreme as it was.
We can see that cold front that is starting to drop out of Canada.As the ridge continues to fall apart and cooler air moves in a loft. It is going to increase our risk for thunderstorms. The cold front is going to slowly drop south. Those north of the front will see temperatures cooling off. South of the front will continue to see the hot temperatures and high humidity. With heat indexes in the upper 90s into the 100s. As the front drops into the hot tropical air mass. We will see rain showers and thunderstorms break out this afternoon into tonight. Some of these storms will be strong to severe. Here is a look at the current convective outlook from the storm prediction center.
We can see there is a marginal risk for severe weather across Pennsylvania, New Jersey, Maryland and Delaware. The risk will be strong damaging winds, frequent lightning, some hail and with all the moisture in the air heavy downpours can be expected. The front will continue to drop south into the middle Atlantic and I-95 corridor tonight into tomorrow. Here is a look at tomorrow's convective outlook.
Tomorrow night The cold front is going to end up stalling out It will be hanging around Friday Into Saturday. So for Friday and Saturday We can expect rain showers and some thunderstorms. The storm shouldn't be severe. The front will have pushed the high temperatures and humidity out of here. Then on Saturday The stationary front is going to start to move back into the region as a warm front. As the front moves through we will see some widely scattered rain showers and maybe some thunderstorms. Sunday will see a cold front move through the region bringing the chance for rain showers and scattered thunderstorms. We are going to heat back up for next week. But we're not going to have the monster ridge that caused the record breaking heat. We will have to watch a shortwave that's going to drop down out of the Canadian prairies and moving across the Great Lakes Monday night into Tuesday. With a cold front that could set off the possibility of severe weather here in the Northeast. For Wednesday we should be dealing with high pressure overhead.
So next week it will feel like summer. But it won't be the super hot weather we've just gone through.
Thanks for the optimistic good news. Is this a record breaking heat dome for NY and New England?
ReplyDeleteThere were years like for example 195 that had longer heat waves and higher heights in the heat dome

DeleteThis thing has too go,seriously.I set the Alarm on my Weather Station for 105.The thing goes off at 5:40 yesterday afternoon after it had dropped from 98.The. Sun was getting lower and it dropped to 95 then I hear this beeping.I had no idea what it was.When I saw the blinking on the screen I silenced it and went outside,it was unbelievable.I saw some 100's in Connecticut but 99 was the highest around here.Can there be a surge like that after it starts to cool off?

1st thing make sure the thermometer is not in direct sunlight at anytime during the day. Make sure it's 5-6 ' off the ground. And make sure it has plenty of air flow around it. Things like air currents can cause temperatures to rise at a time you wouldn't expect them to.
ReplyDeleteSensor never sees the Sun.On the North Side of house.Always air flow the fence creates an alley so there is a slight breeze even when the air is calm.This was certainly a huge rise in temp.I went outside and it hit me in the face.I had been able to sit under the patio when it was 95-98 but not then.The house temp. that had not gone above 70 went to 76.7 in a hour.First time this A/C could not keep up.A/C was finally shut off at 6 this morning,after 4 1/2 straight days.
