These little systems can be full of surprises. This one looks straight forward.
Tonight: Light snow arrives around 10 - 11 pm and continues most of the night before taping off by 8 am. Most accumulation will occur from midnight to 6 am. Again mostly light snow, with some heavier bursts possible.
The HRRR model is handling the storm very nicely. This is a simulated radar pic for tomorrow morning at 4 am and next to it is the HRRR predicted snow amounts. These will be some "fluff" factor in this snowfall that could boost the amounts a little more.
It is winter. It is acting like winter.
Enjoy. It is the day the Lord has made, rejoice and be glad in it!
