At this time, snowfall accumulations of up to 2 inches are expected as the rain/snow mix briefly changes to all snow. Then dry and warmer conditions will return to the region during the day on Wednesday with highs in the upper 40s to low 50s.   (Please visit http://weather.gov/lsx for more information.)
