Boy did we get lucky on this one.
Monday's long duration snowfall left behind a trail of respectable snow totals...but nothing like what the next phase of the storm will deliver to Chicago tonight.
Officially 4.7" at MSP Airport recorded 4.7" of snowfall with the latest system. That puts the season to date snowfall at MSP at a healthy, ice dam dripping 60.4". Here are the relative numbers for MSP.
Season snowfall: 60.4"
Average to date: 34.1"
Departure from avg: +26.3"
January snowfall: 17" (+3.5")
If we maintain our current snowfall pace the rest of the winter we are on track for about 80" of snow. That would approach the 5th snowiest winter on record. It would also be the snowiest winter in 19 years. The last time we had 80"+ was in 1991-'92 (Halloween Mega-Storm) when we stacked up 84.1" of snowfall!
Here's the final NWS tally on Monday's snowfall:

Arctic air is sliding south again in the wake of Monday's snow event. Temperatures plunged into the -20 and even to -35 near the center of the arctic air mass in North Dakota and eastern Montana overnight.
The chill will keep Minnesota in the deep freeze (and hopefully stop my ice dam covered window sills from dripping temporarily) through mid-week before temperatures moderate by late week.
Brief late-week "thaw?"
Temperatures will rebound Thursday into Friday, as milder Pacific air begins to move in from the west. 20s should return Thursday...with lower 30s possible in southern Minnesota Friday and Saturday.
Another shot of arctic air is due next week.
Bigger thaw ahead?
There are signs that a more substantial thaw could emerge for the Upper Midwest by late next week into the following weekend. Indications are the upper air pattern may shift, and the polar vortex over Hudson Bay may slide east toward Greenland temporarily.
That could allow milder winds form the Pacific Ocean to take hold over the upper Midwest. If the pattern takes firm hold...it could mean a few days of 30s and even a shot at 40 in Minnesota by the weekend of February 12th.
Chicago: Biggest blizzard in history?
A major "snow bomb" is racing toward Chicago today and tonight. A powerful storm is taking aim with what meteorologists refer to as some incredible "dynamics." The storm has the potential to become the biggest in Chicago history.
Here is some of what the Windy City can expect tonight and tomorrow according to the Chicago NWS.
-Snowfall totals over 20"?
-Snowfall rates of 2" to 4" per hour
-Wind gusts of 50 to 60 mph
-5 to 10 FOOT drifts
-Waves as high as 25 FEET on Lake Michigan
-Severe lakeshore flooding
Blizzard warnings are flying for the entire Chicagoland area.
Check out some of the snowpacolyptic language from the Chicago NWS.

This looks like an epic blizzard for Chicago. Only 3 storms in history have produced over 20" of snow in Chicago. 23" fell in January of 1967, and The "Mayor Jane Byrne" blizzard (20.3") slammed Chicago and changed the political landscape in 1979.
This storm will be Chicago's version of a Nor'easter on the shores of Lake Michigan. With potential wave heights reaching 25 feet severe lakeshore flooding is expected, and waves will likely crash over Lakeshore Drive. I covered similar events working for WGN in Chicago in the 90s where I broadcast live from near the Chess Pavilion as waves pounded "The Drive."
The storm will rage on and move east this week...and could dump 1-2 feet of snow from Chicago through Detroit and all the way east into Upstate New York and Boston!
I know I'm feeling better now about shoveling a paltry 4" from my walkway today!
Might want to check your math - I'm pretty sure that the 1991-1992 winter was 19 years ago, not 29.
I'm from MN, living in Chicago now. They're all really going nuts for this storm - as they should. Luckily my place of employment is planning on being closed tomorrow. I wouldn't have gone in anyway. I have to admit, I've wanted a major snow storm here all winter, I was jealous of your early December storm. I guess we're going to finally get ours....
