1/23 - 1/26 Two Wave Major Winter Storm

BTW, i picked up 1.5" last night and my snow depth is 8-9".  If we tack on another 6-9", we'll be approaching a foot and a half snow depth.  That will be as deep as I can remember in many years.  And I can't remember the last time we had this deep of a snow depth for this long of a period of time.  We're about to hit 30 days straight with several inches on the ground.

Yea NAM is slightly drier than 12z too here. Looking like 6-9” for CR/IC. Far cry from the 12” it was looking like we could have yesterday, but respectable I guess. 

2021-22 Snowfall: (Hiawatha)

TOTAL: 10.2"

(12/28: 3.0") (12/29: 0.8") 

(1/1: 6.4")

It should be fun for the seNE/swIA snow geeks.  Much of their snow will fall during daylight, too.

This may end up a bust for northern Illinois if these models keep showing it weakening more. 

Watch is on life-support sad to say

There's my 2" in the making:

 

.DISCUSSION...(This evening through next Sunday)
Issued at 314 PM EST Sun Jan 24 2021

- Accumulating snow Monday night into Tuesday-

We have issued a Winter Weather Advisory for this system for
Monday night into Tuesday. Expect a period of significant snowfall
from Monday evening into midday Tuesday. The last 3 runs of the
GFS and it`s ensembles (nearly all 30 members) and ECMWF and most
if it`s ensembles have been showing this system since the
beginning early last week (18th). The SREF, HRRR, HREF, all show
this system too. The heaviest snowfall will between I-96 and I-80.

As we have been writing about this all along, it is a shearing out
upper wave moving into confluent flow at mid to upper level, as it
moves into the Great Lakes. Typical of this type system, the
snowfall and total precipitation diminishes as the system tracks
eastward. So the western parts of our CWA will have the greatest
snowfall from this storm. We are thinking a general 2 to 4 inches
from this event with the most of the snowfall happening between
midnight and mid morning Tuesday.

DVN thinks the trend to crap out the system is overdone on models, or at least their AFD reads that way. They’re going 8-11” along I-80 in Iowa. That seems optimistic given recent guidance but theyre the experts.

Good to hear.  Heck, we still have time. maybe models trend back tonight?  Doesn't seem like this event gets any closer.

18z GFS looks like it nudged slightly N from 12z

And is still really quite wet relative to the absolute debby downers that the EC/NAM/HRRR are.
