From Sunday to Wednesday, the heat will reach dangerous levels with highs between 97 and 102 degrees. But our temperatures will really soar from Monday to Wednesday as highs are expected to hit triple digits. According to our NEXT Weather team, our last 100-plus degree day was in July 2012 when we hit 101 degrees! An extreme heat warning is in effect now through Wednesday for all of Pennsylvania, New Jersey and Delaware counties along the I-95 corridor. Our NEXT Weather team is guiding us through this heat wave, keeping us prepared and protected.
