Hot but less humid Sunday in Philadelphia, tracking showers and storms. See the weather forecast.
Our Sunday got off to an unusually warm and humid start with low temperatures in the low-middle 70s in most locations around the Philadelphia area. In fact, the low temperature in Philadelphia this morning of 76 degrees tied the record for the warmest low temperature ever recorded for today's date.
The warmth and humidity will continue for the rest of the day, especially in areas south of the I-95 corridor. Temperatures will climb into the upper 80s and low 90s this afternoon as a cold front sweeps through the area from the northwest.
This cold front will not necessarily usher in cooler air, but rather some relief from the humidity north of Philadelphia through the second half of the day. Areas south of Philadelphia, near where the cold front will be positioned, could see a few showers and thunderstorms through this afternoon into this evening. This will include shore communities that will have about a 30% chance of showers and thunderstorms.
By Monday, the cold front will lift back to the north as a warm front and bring back the humidity and a few scattered showers or storms, especially across southern and western zones. High temperatures will be near 90 degrees once again with heat indices in the mid-upper 90s, but likely just below heat advisory levels.
Tuesday will be a NEXT Weather Alert Day, and the day to watch closely. A strong cold front combined with increasing wind shear and instability will set the stage for some severe thunderstorms. Timing and storm evolution still need to be fine-tuned, but damaging wind potential will be on the table.
Behind that, things calm down — Wednesday through Friday look seasonable with mostly sunny skies, lower humidity and high temperatures in the upper 80s to right around 90 degrees.
