We have a tornado watch posted for the same area that we did yesterday though the Storm Prediction Center did add the South Jersey counties this time around. They cover the counties in Western New Jersey from Warren & Hunterdon Counties southward and westward across most of Pennsylvania with the exception of the extreme north. Bear in mind that last night’s tornadoes occurred in areas inside as well as just outside the watch area so if you are in the Eastern Counties of New Jersey not under the watch I would pay close attention to the weather this afternoon.
The satellite picture this afternoon looks much the same like yesterday. A warm front lies just south of New York City. Daytime heating is sending temperatures in the 70s and 80s south of that warm front while it is in the 60s to the north. Regional & local radars are picking up on the activity developing to the west in Pennsylvania. The thunderstorms will be coming in a bit earlier than yesterday and could impact the evening commute so allow yourself some extra time.
LOCAL RADAR NEW YORK CITY
NEW JERSEY COUNTIES INCLUDED ARE
ATLANTIC BURLINGTON CAMDEN
CAPE MAY CUMBERLAND GLOUCESTER
HUNTERDON MERCER SALEM
Thunderstorms will be moving through this evening and into the first part of tonight. They will also impact areas to the east of the watch area as well out to Long Island, Southern New England, the Hudson Valley, and Eastern New Jersey. Flash Flood Watch is also posted for much of New Jersey & Eastern Pennsylvania. A second day of potential heavy rains means the threshold for flooding is low. It won’t take much to cause flooding from heavy rains.
Keep your eyes on the radar this evening. Once the thunderstorms move out weather conditions will improve tonight. Then another and final cold front approaches on Thursday with another round of late day thunderstorms until better weather arrives on Friday.
