Philadelphia, PA – The NEXT Weather Center is tracking several key weather patterns affecting the Philadelphia area this week. A high-pressure system moving in from the north is set to bring cooler, drier air from Canada, giving residents a few days of fall-like weather before temperatures rebound over the weekend.
Cooler Temperatures and Fall Conditions
Expect morning lows to dip into the 50s Wednesday, with widespread 40s to low 50s by Thursday and Friday morning. Residents may want to break out sweatshirts or light jackets, as the cooler air will make the mornings feel distinctly autumnal.
The high-pressure system is expected to remain over the region for a few days, keeping skies mostly clear and rain-free until at least Wednesday of next week.
Weekend and Early Next Week Forecast
As the high pressure moves east, temperatures will rise, bringing a return to warm conditions:
- Saturday: High 81°F, Low 52°F
- Sunday: High 82°F, Low 55°F, sunny and warm
- Monday: High 84°F, Low 58°F, sunny skies
- Tuesday: High 84°F, Low 63°F, unseasonably warm for this time of year
Earlier in the week, expect:
- Wednesday: High 73°F, Low 58°F, cooler and sunny
- Thursday: High 71°F, Low 51°F, feels like fall
- Friday: High 73°F, Low 49°F, partly cloudy
Tropical Weather Update
Meanwhile, meteorologists are monitoring Hurricane Imelda and Tropical Storm Humberto in the Atlantic.
- Imelda is now a hurricane and is expected to strengthen as it approaches Bermuda Wednesday evening.
- Humberto continues to weaken to the north.
Authorities advise that rip currents and rough surf will be felt along all beaches and shore points, and boaters should exercise caution and monitor local alerts.
While the tropical season still has two months remaining, forecasters note that the region is past the peak, with no landfalling systems in the continental U.S. so far this year.
