REGIONAL RADAR
Regional and local radars are very busy this evening. Look for the threat for thunderstorms to continue this evening and into the first part of tonight. For now much of the thunderstorm activity is north of Route 78 in New Jersey north of Long Island. We are seeing thunderstorms developing further south in Pennsylvania and they will likely impact areas that missed the first batch will likely get hit with the second round.
LOCAL RADAR NEW YORK CITY
LOCAL RADAR PHILADELPHIA 
Overnight as the front passes we will see it slow to a crawl and a second wave of low pressure will bring more downpours overnight into Tuesday. Some of the rains will be heavy and rainfall amounts of 1 to 3 inches will be common with some locally higher amounts possible We remain in a moderate risk for flash flooding and flash flood watches continue into Tuesday.
The plan is for the front to edge far enough east so that we could see improving weather conditions during Tuesday afternoon especially north and west of the coast but the pace of the front is a literal crawl so it may be a fight to clear things out Tuesday afternoon and we may have to wait until Wednesday to see significant improvement. Temperatures Tuesday will be only in the 70s. Wednesday and Thursday we will see sunshine assuming the front keeps moving with low humidity and temperatures back into the low and mid 80s. We should warm up and turn more humid as we head into the weekend with temperatures getting back to 90 or better but for now it doesn’t seem as if we will get back to the heat of this past weekend.

NEW TROPICAL DEPRESSION FORMS OFF THE FLORIDA EAST COAST
Satellite picture show a low level circulation as formed in the Bahamas and tropical depression number 3 has formed in spite of hostile winds in the upper atmosphere. Conditions are only marginally conducive for development over the next day or so before becoming hostile again as an upper trough moves off the East Coast. We will talk more about this in our live stream on my Youtube Channel later this evening or from the video section on my weather app.
