Temperatures topped out around the upper 40s to lower 50s today with spotty showers and even some briefly heavier rain with small hail over parts of the East End late this morning. An additional spotty light rain shower cannot be ruled out through early evening, but it is drying out with clouds clearing this evening.

Tonight, skies clear out, and that sets the stage for another cold night across the area. A freeze warning is in effect, with temperatures dropping into the upper 20s and lower 30s. Make sure to protect any sensitive plants and take precautions as we dip below freezing under mainly clear skies. Freeze Warning through 9 a.m. Tuesday.
