12/28 - 12/29 Plains/MW/GL's Snow Event

12z Canadian is fantastic for the Black Hills; with almost continuous snow here from Hour 48 through Hour 120.

 

Of course the Canadian is terrible outside of 48 hours; so take it with a grain of NaCl...

 

As bad as the EC is for the Black Hills (maybe 0.2 - 0.4 LE depending on altitude); I'm still quite optimistic.  The GFS, Canadian, & UKMET all look good; they all look like at least 8 inches or more of snow from Thursday through Sunday.

 

Truth be told; the 12z EC was a slight improvement over the terrible 0z run for this area.

 

The ratio for the month has averaged around 23:1 out here...

The NAM has the Friday system cutting through the heart of Iowa.  Similar to the Euro.  

 

And it's totally gone on the 00z.

00z EPS mean likes C IA/C IL as the corridor of the heaviest precip...00z Euro control hits all of IA with at least 2-4" and into C IL/C IN...E NE gets clipped as well...N IL roughly 1-2"...Nice overnight trends that did not look all to well yesterday.  Don't throw in the towel in a pattern like this.  These waves tend to deliver some interesting meso scale banding in such an cold air mass.

Yup, DMX mentioned banding but are not getting aggressive with accumulations. Said maybe iso 3". Did mention potential advisory but with current wind chill headlines they dont want confusion.

12z NAM showing a quick burst of snow for C IA peeps overnight tonight with 2-3"...MSP rush hour may not be to nice....

Several inches of very dry snow falling on frozen concrete during rush hour equals disaster. I’m already thinking about working from home tomorrow so I don’t have to deal with that madness. 2-5” in my point and click for tonight thru tomorrow morning.

Best solution bud. I do that all the time, if I must. :)

Models are very weak with the Wednesday night/Thursday wave.  Here's the UK, which only has about 0.03" in CR.

The UK is more robust Friday, with a more sw track.  Here's the UK map through the weekend.  A last wave adds a bit to Nebraska over the weekend.

The 12z euro continues to show the more robust Friday wave a bit farther northeast, missing Nebraska.  The total precip map isn't loading, but here's the 10:1 snow map through the weekend.

My .02 is that we can’t overlook the fact that 00z and 12z GFS have been relatively consistent with storm track and placement since last Thursday. GFS also caught on to these brutal temps. Appears that EURO is playing catch-up this time around.

Euro is playing catch up? Please elaborate.

2021-22 Snowfall: (Hiawatha)

TOTAL: 10.2"

(12/28: 3.0") (12/29: 0.8") 

(1/1: 6.4")
