PHILADELPHIA (CBS) — Our heat advisory continues Tuesday as excessive humidity combined with seasonably hot temperatures will yield heat index values near 100 degrees this afternoon. Fog has cleared out along the coast but will linger in the city and suburbs before eroding by midday to reveal some steamy sunshine.
Late-day thunderstorms are again likely today yet the coverage looks to be less than yesterday. Rain could be heavy but with slightly lower atmospheric moisture content, the threat for flash flooding should only be localized.READ MORE: National Night Out Aims To Improve Police-Community Relations During Violent Year In Philadelphia
