Warm More Humid Downpours Thunderstorms Moving East
We have broken out into partly sunny skies and it is noticeably more humid this afternoon. Dew points have climbed up into the 60s and temperatures are into the 80s. To the west some showers and possible thunderstorms are starting to make their move eastward and they should reach the coastal areas this evening and for the first part of tonight. The Storm Prediction Center has made a few adjustments this afternoon as they increase the risk to the south over Delaware and Maryland but they leave the northern extent of the marginal risk for severe weather in about the same place which is near Route 195 in New Jersey and Route 78 in Pennsylvania. General thunderstorms are indicated elsewhere in the Northeast.
The satellite picture this afternoon shows clouds to the west and hazy sunshine from Eastern Pennsylvania to the coast of Southern New England.
Regional radar shows a rather large area of showers and some developing thunderstorms to the west with some heavy rain moving east. Meanwhile the local radars haven’t picked up any activity yet but they should start to come in range as the evening commute progresses.

Tonight look for some showers and thunderstorms with some heavy downpours. Not everyone will participate in this equally though the risk is there area wide. They should be gone during the early morning hours. Thursday we will see clouds and some sun. It will be very warm and humid until the cold front passes later in the day. There could be another shower or thunderstorm in the afternoon as the front passes. Highs will be in the 80s and the humidity will be high.
There are no changes in our outlook for Friday and Saturday. High pressure builds in from the north and that should push the cloud line south into Virginia east to the Delmarva Peninsula. North of there it should be partly to mostly sunny with highs in the middle 70s to lower 80s. Saturday looks good with sunshine and highs in the mid 70s to lower 80s. Sunday we see sunshine to start with some arriving clouds with highs in the 70s to near 80.
It appears that tropical moisture from an old disturbance in the Western Gulf of Mexico will be on hold until a low and cold front from Canada swings into the Great Lakes and lifts the southern moisture up the coast. It looks like we could see downpours here Monday and possibly into early Tuesday before this system clears the coast and weather conditions improve behind it for the middle of next week. At least the weekend still looks to be a good one with no rain in the forecast from Friday through Sunday.
