The sleet could be heavy at times, but that warm air is advancing quickly so the transition to freezing rain could occur pretty fast; perhaps before sunrise. From what I am seeing right now, surface temperatures will likely stay at or below freezing for most of the day, leading to a heavier amount of freezing rain and less snow/sleet. Too bad. Ice is simply bad. Snow and sleet can at least be moved out of the way.
Be careful. The rain will wash this stuff away starting early tomorrow morning.
