2/20 - 9:30 - ICE STORM

Oh what to do, what to do... The GFS is calling for a pretty good lickin' of an ice storm, with temps really warm above a few thousand feet and temps cold at ground level. The NAM is similar, but its warmer aloft. The NWS is even floating the idea of issuing an ICE STORM WARNING instead of a winter weather advisory as well.

This will start tomorrow afternoon from 2-4pm as some snow and sleet. Rush hour tomorrow afternoon will be a mess for the most part. As night falls the temperatures aloft will rise and then we'll transition to freezing rain. That's worse than sleet since you get sheets of ice instead of manageable pellets. I think we could get a sizable accumulation of ice too, over .25" possibly. We should be all rain by Friday afternoon.

So, this isn't a snow event by any means. I think there might be a 2-hour delay or cancellation for JCPS on Friday if we do get ice accumulation. We'll see how that works out though...
