Thunderstorms Continue Tonight As Cold Front Passes Weather Improves Sunday

Thunderstorms Continue Tonight As Cold Front Passes Weather Improves Sunday

Downpours and thunderstorms have been running around all afternoon from place to place and from time to time. Some of the the thunderstorms across parts of Central and South Jersey were strong enough to produce some flash flooding and even a tornado warning for parts of Southeastern Pennsylvania late today. These were what I often refer to as renegade thunderstorms that form out well ahead of the frontal line of thunderstorms which is approaching now from upstate NY,

Two lines of thunderstorms are developing on the regional radar and are showing up on the local radars. The lead line is narro and runs from Northwest New Jersey to Central Massachusetts while a  second more potent line is behind it moving eastward into Northeast Pennsylvania and soon into the Westernmost Catskills. There is some question as to how much intensity these lines of thunderstorms will hold on to this evening. After 8 or 9 pm both lines should start to weaken somewhat as they move east. We will watch and see. Right  now we seem to be heading into peak strength for these storms in the next few hours.

Once these storms move through they should disappear from the radar and weather conditions should improve somewhat overnight with leftover clouds and lows in the upper 60s to mid 70s with high humidity.

There are no important changes in the outlook for Sunday or this coming week. Humidity will be slow to drop on Sunday so it still may be on the humid Sunday through most of the area into Sunday afternoon. We are looking for clouds and some sun for Sunday. Being that we will be close to that boundary, areas in Southern Pennsylvania and Southern New Jersey could see a shower or thunderstorm around midday or early afternoon.

Areas to the North from Northeastern Pennsylvania eastward to Southern New England will likely be okay on Sunday and the humidity could start to drop a bit in the afternoon. Sunday’s highs will be in the low to mid 80s. We should see that dry air sink southward Sunday night. Monday should be a nice day of sunshine, reasonable humidity and highs in the low to mid 80s. Tuesday looks good too with sunshine, reasonable humidity and highs in the low to mid 80s.

Severe Weather Risk Late Today Lower Humidity Arrives Late Sunday Monday

The next cold front will be dropping into the Great Lakes late Wednesday so the heat and the humidity will start to come back with highs Wednesday in the mid 80s to some lower 90s. The front will increase the chances for showers and thunderstorms on Thursday with highs in the 80s. This front should move along bringing drier air for Friday and for at least the start of next weekend!
