Is it time for radar hallucinations yet?  Looking at radar about 20 minutes ago, it appeared that our show showers were going to be non-existent, now looks like they may have some life!  Going to be fun watching radar this morning!

Unlike a summertime line of storms, a snow band probably won't show up on radar very well, especially in the mountains.

They seem to be moving fast and looking out West I see Snow Squall Warnings up. That's new
