Weather Forecast for Philadelphia Region: A Mix of Conditions with Tropical Influence
The extended weather forecast for the Philadelphia region over the next week shows a mix of conditions with some unsettled periods, potential scattered showers, and a notable tropical influence off the coast.
Throughout the current week (Monday 8/18 to Sunday), temperatures will remain near seasonable values, mostly in the 70s to low 80s°F with moderate humidity.
A cold front is expected to pass through on Friday, then stall to the southwest on Saturday before returning as a warm front on Saturday night and Sunday. This will bring scattered showers and potential thunderstorms on Saturday night through Sunday morning, with continuing chances of storms on Sunday afternoon.
Early to mid next week will be hot and humid before another cold front arrives on Wednesday or Wednesday night, which ends the heat and humidity, leading to a cooler and more comfortable air mass for about a week. The week after the cold front is expected to be mostly dry with slightly below average temperatures.
For the upcoming weekend (Saturday and Sunday), expect some afternoon scattered to isolated storms, mainly north and west of Philadelphia, with typical August temperature and humidity levels.
Regarding potential tropical activity, the region will be influenced indirectly by Hurricane Erin, which is forecast to remain well offshore but will affect shore and marine conditions. This will cause large long-period swells and high surf from Wednesday through at least Thursday with 8-15 foot seas offshore. Coastal communities may see dangerous rip currents, beach erosion, and some coastal flooding. However, no direct tropical storm impact is expected over Philadelphia. Rip current warnings are in effect through Thursday due to Erin’s influence.
In summary, Philadelphia will have typical late summer temperatures with intermittent showers and thunderstorms mainly over the weekend. Tropical activity offshore (Hurricane Erin) will not directly affect the city but will create dangerous conditions along the coast midweek. A cooling and drying trend will follow a cold front arriving on Wednesday or Wednesday night next week.
Stay tuned for hourly updates, weather radars, and weather blogs for further information. Humidity will be noticeable on Tuesday, but heat index values will stay just shy of advisory levels.
With tropical Hurricane Erin expected to indirectly influence the region, the latest news reports detail potential hazardous coast conditions from Wednesday through Thursday due to large swells and high surf. As for the weather forecast, the law mandates regular weather updates, with Philadelphia set to experience typical August temperatures, intermittent showers, and thunderstorms, primarily over the weekend, followed by a cooling and drying trend next week.
