It'll be a cool night tonight with lows dropping into the low and mid 40s, perhaps even into the upper 30s in the Lehigh Valley. Skies will be partly cloudy with north winds shifting from the southwest at 5 to 10 mph.
Wednesday will be the warmest day of the week. We'll start with sun but clouds will gradually increase through the day. High temperatures will range from 70 to 75 across the region, maybe even higher than that if the sun sticks around longer. The only exception will be the Shore where a seabreeze will hold temperatures in the 60s. Winds will be out of the southwest at 10 to 20 mph.
Showers and thunderstorms will arrive Wednesday night, associated with a cold front. Behind that front will be cooler temperatures for Thursday and Friday, although it will still be pleasant.
