Discussion

A powerful cold front will blast through the region overnight and we will have stormy conditions between about 7pm and 3am to include heavy rain, thunderstorms, localized flooding, and strong-to-damaging wind gusts of up to 50 mph or so. Temperatures ahead of the front this afternoon will climb to near 70 degrees and there will be a couple of showers around, but also some brightening skies at times. The heavy rainfall expected in the overnight hours throughout the I-95 corridor should be in the 1-2 inch range although isolated 3 inch amounts are possible. An important factor with respect to the heavy rainfall expected overnight is that the ground has just gone through a frigid period and is still quite frozen just beneath the surface. As a result, absorption will be quite difficult and there is likely to be substantial runoff tonight with the heavy rainfall; consequently, localized flooding (streets, streams) is quite possible. Behind the front, temperatures tomorrow will peak early in the day and should drop into the 30's during the afternoon hours and then will struggle to rise above the mid 30's on Friday. A few disturbances have the chance to generate some snow shower activity around here over the next few days.
