Rain chances in the forecast all next week for Philadelphia
This is your official "Umbrella Alert" for next week. Each day will be humid with a chance of showers or thunderstorms. Temperatures will bounce between the 80's and 90's.
Monday's rain differs from the rest of the week because it will be the remnants from Tropical storm Chantal (pronounced shahn-TAHL). The storm will make landfall in the Carolinas on Sunday and travel northward, dumping 4-6 inches of rain while rapidly weakening to an area of low pressure.
A cold front sweeping eastward across the region will guide Chantal's remnants across Philadelphia Monday. Scattered thunderstorms and showers are possible, mainly in the afternoon and evening.
Tuesday through Friday, a series of disturbances arrive bringing scattered showers and storms at some point each day.
