HEAT HUMIDITY LOW TO MID 90S
HEAT INDICES NEAR 100
BREAK STILL FORECAST LATE THURSDAY
Today (for some areas) it will be the second day of 90 degree plus highs. A vast majority of the area yesterday fell just short of 90 but it is the humidity that remains a huge issue. Dew points are in the 70s today making for a very oppressive environment. Heat Indices will be 100 or higher in some spots this afternoon as highs reach the low to mid 90s.
In spite of all the heat the big high off the east coast is creating a rather stable atmosphere so it is unlikely to see any isolated downpours or thunderstorms this afternoon and evening. Try and stay cool in this late summer heat have.
The sinking air under the big high is even preventing clouds from developing at least so far today and the regional radar shows a very quiet start to the day across the Northeast & Middle Atlantic states. This will change somewhat on Wednesday as it will be another day of heat and humidity. However there is a weak disturbance that will be running out ahead of Thursday’s cold front. That could trigger a few pop up thunderstorms in the late afternoon and evening. Wednesday will be another day of highs in the low to mid 90s and heat indices near or over 100.
Thursday brings a cold front and this will be the last day for 90 plus and it will be the best chance for thunderstorms this week. Right now the Storm Prediction Center is not forecasting any risk for severe weather but we wonder whether there might be some scattered strong thunderstorms when the front comes through. We think the risk might be there for a few isolated stronger storms. Then the front moves south and stalls. The issues for Friday and the Labor Day holiday weekend remain unchanged. Onshore flow means cooler highs Friday & Saturday with highs probably not out of the 70s. We will probably have plenty of clouds around and the risk of passing showers.
Sunday brings the front back northward and that will take temperatures back into the 80s. There will be the risk for showers or a thunderstorm Sunday and Monday. We want to emphasize that THIS WEEKEND WILL NOT BE A WASHOUT and that most of the time it will be dry. It just won’t be picture perfect ideal for the last vacation weekend of the summer season.
