Another Hot Humid Day Severe Weather Risks Grow Wednesday
We are going to see our 4th day in a row of 90 degrees plus across the area from Eastern Pennsylvania to Southern New England south to Northern Virginia and Maryland. The highs might technically be a few degrees lower than yesterday’s brutal 95 to 100 but I somehow doubt anyone is really going to notice the difference. The humidity is high and we do at least have a mechanism to trigger off some thunderstorms. There were none yesterday but there should be a few today.
New Jersey south of Route 195 and Pennsylvania mainly south of Route 80 cover the risk zone today. We are expecting thunderstorms will be scattered in nature late today and some isolated severe thunderstorms will be in the mix. North and east of NYC in Southern New England no thunderstorms are forecast with stable atmosphere in place. So those areas it is simply just hot and humid with highs reaching the upper 80s and lower 90s.
The day starts off with a quiet radar but we will see activity pick up on the regional and local radars later today and into tonight.
LOCAL RADAR NEW YORK CITY
We are lying on the edge of the heat ridge that covers the southern half of the US and the west to northwest flow that lies near the Canadian border. So far the ripples in that flow are sending weak weather systems through and we have one such system today but a stronger one will be approaching on Wednesday.
There could be a few scattered showers or a thunderstorm running around early in the day but it is late in the day after another day of strong daytime heating and high humidity that we could see some solid thunderstorm activity. The Storm Prediction Center has upped the ante to a slight risk for severe weather on Wednesday. Highs Wednesday will be in the low to mid 90s.
The hope is that one of these fronts will bring some real humidity relief. Another one arrive late Thursday but there will be perhaps a scattered shower or thunderstorm with that one. Highs will be in the upper 80s and lower 90s. Yet another pass on Friday with highs in the 80s and nothing more than a pop up shower or thunderstorm.
The weekend brings some temperature and humidity relief but it won’t be a lot of relief and the models have backed away from the strength of the northwest flow out of Canada. We take what we can get here. The weekend is looking a little less humid but still warm with sunshine for both Saturday and Sunday with highs in the 80s.
