Philadelphia, PA – After days of sweltering triple-digit heat indices, a sharp temperature drop is on the way for eastern Pennsylvania and southern New Jersey. Overnight lows are expected to plunge into the 50s by Thursday, bringing the first real relief from a miserably hot July.
Cooler Air Moves In
According to the National Weather Service in Mount Holly, a cold front moving through the region on Thursday will usher in significantly cooler and less humid air. Mount Pocono could dip as low as 54°F Thursday night and 53°F on Friday morning. Other areas like Hackettstown, Reading, and Allentown will experience lows in the mid-to-upper 50s through the weekend.
Milder Cooldown in Larger Cities
In larger cities like Philadelphia, Trenton, and Wilmington, the cooldown will be a bit milder, with lows in the mid-60s. Highs will fall from near 100°F to the upper 70s by Friday, providing much-needed relief from the oppressive heat and humidity. The region’s summer heat will be replaced with more seasonable temperatures, which aligns with NOAA’s 6–10 day outlook, predicting below-normal conditions through early August.
Health and Safety Tips
Residents should take full advantage of the cooler stretch by reducing energy usage and hydrating after a taxing heat wave. It’s also a good time to open windows for natural ventilation, but be mindful of allergy-sensitive individuals as pollen counts may still be elevated.
The cooler temperatures and lower dew points are expected to hold through early next week, making for a much more comfortable period. Stay tuned for updates if any severe weather develops with Thursday’s cold front.
