A cold front from the west will move through the Philadelphia region today and is expected to produce heavy rains and thunderstorms, according to the National Weather Service in Mount Holly, setting up potential tornado conditions.
Some of the storms could produce gusty winds and heavy rain, the weather service said. The precipitation is forecast to start early afternoon and continue through late tonight, possibly dumping more than an inch of rain before it moves through.
In some areas, conditions will become favorable for possible tornadoes. Hail and strong winds are also possible. A tornado watch is in effect until 5 p.m.
Overnight temperatures should drop to 50, but could fall into the 40s, bringing us much closer to fall conditions.
Tuesday should be much better with sun and a high of 71 and a comfortable low of around 52.
The forecast calls for a slight chance of rain on Wednesday, but it should be mostly sunny with a high of 68.
A slight chance of rain remains for the rest of the week, through Saturday. But most days should experience partly sunny conditions.
