Latest Models: GFS 22.5″…NAM 25.5″!
I'm working on a longer version of this post, but I wanted to get the headline out there.
It looks like I'm going to raise my snowfall forecast for the metro and much of southern Minnesota for a 2nd time.
I am now leaning toward a storm snowfall total of between 10" and 20" by Monday noon for much of central and southern Minnesota, including the Twin Cities metro.
This includes Redwood Falls, Willmar, The Twin Cities, Eau Claire & Red Wing.

The 00Z (6pm) NAM run is in. The model is cranking out an incredible 1.54" liquid...and a storm total snowfall of 25.5" for MSP Airport!
The latest 18Z (noon) GFS run came in at 22.5" for MSP.
The models are producing incredible snowfall rates of up to 2" and 3" per hour Sunday late PM & evening!
The other trend is to slow the storm about 3-6 hours. It looks like snowfall will begin in the metro between 6am & 9am Sunday.
More soon....
