In what might be viewed as the advancing spring’s “warning shot” to the remnants of winter, strong thunderstorms are possible late Wednesday afternoon and evening in the Philly region, with an outside chance of an isolated tornado.

In Raleigh, Durham and Chapel Hill, there’s a chance of showers before 10 a.m. Wednesday. Expect showers and possibly thunderstorms between 10 a.m. and 3 p.m. Showers and storms are still possible after 3 p.m. but not as likely. The high temperature in the Triangle should be around 70 degrees.
