Timing on Monday will be interesting. Looks like the general average is mid morning which will be less of an issue but if you take the common thought that it gets here a few hours before modeled and at least one model (Rgem) has it starting before or near daybreak, for the western 2/3 of PA, it leaves the door open for schools to be closed 3 days in a row and people to call out again. LOL.
Several of the schools around here (some in MD) are cancelling virtual and in place on these snow days.
