Record-high temperatures, storms expected Wednesday as heat wave continues in Philadelphia

After the hottest May day ever recorded in Philadelphia's history, the extreme heat continued Wednesday with record highs in the mid-upper 90s.

A severe thunderstorm watch for the entire Philadelphia region is no longer in effect. The greatest impact is likely to be damaging winds, but large hail is also possible. The tornado threat is low but cannot be ruled out.

A flash flood warning has also been issued for parts of Pennsylvania and South Jersey until 9:45 p.m.

On Wednesday, we set two record-high temperatures in the area, in Philadelphia and Atlantic City. Philadelphia's high so far is 95 degrees (the old record was 94). Atlantic City Airport's high so far is 97 degrees; the record was 96. 

That means this is not only an official heat wave but three straight days of records. That's a pretty historic heat event.

The NEXT big change brings storms, cooler temps

Due to the heat, 57 School District of Philadelphia schools moved to virtual learning Wednesday.

Late Wednesday afternoon, a cold front moves in and will stall overhead, bringing a staggering change with periods of rain, a raw east wind and temperatures hovering in the upper 50s through Thursday.

Friday may clear out and bring some sunshine, though it stays on the cooler side.

Memorial Day Weekend forecast looks cloudy, chilly and wet

Forecast models are falling more in line with what may occur over the weekend, and to be honest, it's not looking good.

Saturday will likely be cloudy, chilly and wet. Sunday will be a bit warmer, a bit less wet, but still way below normal for this time of year.
