Nasty thunderstorms are expected to blast through the state into the afternoon and evening with flash flooding, damaging gusts, and a possible stray tornado. Most of the weather rolls through from 2 p.m. through 9 p.m. with the worst conditions from 5 p.m. to 8 p.m. The strongest storms are likely in central and south Jersey, which includes Mercer, Monmouth, and Ocean counties.

Winds can be in excess of 58mph in severe storms. A stray tornado cannot be ruled out as the front slides across the coastal plain this evening. Flooding downpours of 1-2" of rain can have localized spots of 3"+ of rainfall as well. 

All of this will depend on the cloud cover. If there are more clouds earlier in the day, then the storms won't be as strong later. However, more sunshine leads to stronger storms. 

The weather turns quiet tomorrow where the sky will be partly sunny. It will be calm and pleasant tomorrow with highs near 80. Rain returns for the weekend where Saturday features showers and storms in the later day that carry overnight into Sunday.
