I think the February 2010 storms were during a wall-to-wall cold regime where it didn't warm up until the weekend after the 9th.
Here's my message to the public related to the roads: If you're not forced to be on the roads on Sunday, stay home. Football is at 300 and 630 PM, run to the store today to get your beer and snacks and stay off the roads.
Monday will be an issue with the blowing and the drifting, the blowing and the drifting, but I suspect Governor Shapiro will use the space lazers his folk apparently have to torch the roads clean.
