Philadelphia is currently experiencing a pleasant weekend with sunny skies and mild temperatures, but a significant change is on the way. An elevated fire danger is present to the north and west of the city due to low humidity. As the weekend concludes, temperatures are expected to rise dramatically, with highs reaching the 80s°F (27-32°C) and potentially the 90s°F (32-35°C) by mid-week, which could break records. Cooler conditions are anticipated along the shore due to south winds crossing cooler ocean waters. The week will be mostly dry, with isolated showers possible on Monday, Wednesday night, and Thursday.
