ROANOKE, Va. – Have you ever wondered how it gets cold so quickly? Radiational cooling is how! Last night brought clear skies, calm winds, and dry air. This allowed heat that was absorbed during the day to leave the surface and escape to space during the night.
While Tuesday started off chilly, temperatures will warm up quickly thanks to clear skies and abundant sunshine. Afternoon highs are near 70 degrees in most spots later on.

After the rain pushes through, we are dry for the rest of the workweek. Following this cold front, the jet stream will begin to lift to the north and allow warmer air to build in from the south. The overall trend is warmer and warmer as we head toward the end of April.
