Mostly cloudy but warm in Philadelphia today, NEXT Weather Alert issued for severe storms Monday

The unseasonable warmth continues Sunday with mostly cloudy skies and highs either side of 70. Scattered showers are possible late tonight ahead of a strong cold front to our west. 

Tomorrow is a big day with the Phillies home opener. A NEXT Weather Alert has been issued for Monday afternoon through the evening as a severe storm that includes tornadoes makes its way across upper Midwest, Ohio Valley, Tennessee Valley and Deep South and toward the Delaware Valley.

NEXT Weather Alert issued for severe weather threat

This storm's severe threat moves to the East Coast, and the entire Philadelphia area, later Monday and through the night.

Heavy rain, damaging winds and intense lightning are the main threats, but there is enough spin in the atmosphere for isolated, brief tornadoes, though the greatest threat for tornadoes is across Virginia and the Carolinas.
