Heavy rain continues across the suburbs north and west of the Philadelphia area. National Weather Service radar estimates that two to three inches have already fallen with more heavy rain moving over the same area in the next few hours (it's a process called training).
The wind will also pick up and any thunderstorm could contain wind gusts near 50 mph.
A tornado watch is in effect for Berks, Bucks, Chester, Delaware, Lehigh, Montgomery and Philadelphia Counties in Pennsylvania until 7 p.m. Thursday and in Delaware and South Jersey until 1 p.m. Thursday as storms there could turn into isolated tornadoes.
The rain may let up a little bit, but not for long. A second area of low pressure is located over North Carolina and continues to move north towards the region. This low is what used to be Tropical Storm Nicole and will bring more rain and wind to the area overnight tonight.
This heavy rain may track across Philadelphia and New Jersey, just a little to the east of this morning’s heavy rain. Inches of rain are possible and could result in flooding along with gusty wind and possibly a tornado.
The heavy rain may linger across New Jersey and Delaware, but will be ending in the morning. By the afternoon we may see sunshine along with less wind.
