Thunderstorms South Jersey Spreading Northward

Thunderstorms South Jersey Spreading Northward

We continue to see an active radar as new downpours this afternoon have been forming over Southern New Jersey and Southeastern Pennsylvania with an array of warnings being issued. The threat for Flash flooding continues for everywhere from Eastern Pennsylvania to New England. Breaks in the rain have occurred as well. When that happens as the satellite loop shows we just sit in lots of clouds with temperatures mostly in the 70s.

The morning heavy rain has moved northward into New England while the regional and local radars will likely remain busy into the first part of tonight. It is likely that activity will drop off overnight.

Obviously the threshold for flash flooding is very low with all the rain of this morning and for much of the last 2 weeks. Additional rainfall amounts through Monday evening could total 2 to 3 inches with locally higher amounts probable. Flash Flood Watches continue until further notice.

FLASH FLOOD WATCH IN EFFECT RAINFALL FORECAST THROUGH 9PM MONDAY

Weather models continue to go back and forth on timing which makes using them a bit useless at this stage of the game. The bottom line is the upper trough to the west will continue to fire up heavy downpours through at least Tuesday.

Dew Points Drop Slightly Bad Hair Weather Weekend Next Week

Monday and Tuesday we could see some especially heavy downpours with the upper trough nearby to our west. There should be some rather strong tropical forcing that will result in torrential rains. The question is where and when. I would tend to favor areas north and west of the coast where rainfall has already been excessive. It would be wise to pay attention to radars and forecasts since flooding issues will be front and center.
