The weekend will feature huge jumps in both temperature and humidity. We’ve certainly seen hotter days in the past than I’m predicting for this weekend — but maybe not this summer.
I’m predicting 96 for the high Sunday in Philadelphia, and with the high humidity, a heat index of about 103. The highest temperature this summer has been 95, and the hottest this month was only 91.
Where to Find Relief
The beaches will be the best place to find relief from the heat, especially at the Jersey Shore Saturday. The sea breeze should kick in before noon, limiting the temperature rise. The ocean temperature is still above average, so the cooling won’t be as dramatic as it would be in June.
On Sunday, more of a west wind should prevent the sea breeze from coming in until afternoon, allowing the beaches to heat up. In Delaware, even the beaches should get to 90+ Sunday.
Thunderstorm Relief? And Complications?
Thunderstorms often accompany hot and humid days, and Saturday could be no exception. In fact, any clouds and showers could limit the temperature, perhaps keeping it shy of 90 degrees. But drier air will move in at higher levels of the atmosphere Sunday, and most, if not all of the day should be rain-free.
