Elliott at MU:
Rain will overspread the Lower Susquehanna Valley from west-to-east between 2-5 p.m. this afternoon but should quickly change over to a period of wet snow N/W of I-81 and along South Mountain. How far south/east wet snow occurs will depend greatly on precipitation rates..
Higher rates will result in more efficient dynamic and evaporational cooling, and vice versa. Still, I don't expect more than a few slushy spots on secondary roadways, especially in the higher terrain. However, a coating to 2" of snow is possible on non-paved surfaces..
Any wet snow is most likely between 4-8 p.m. and may lead to areas of lower visibility. Make sure to reduce speed and increase following distance during the afternoon commute to minimize the risk of hydroplaning. For York and LanCo, precip. should fall as plain rain
