Wet snow ends early Sunday; who will win the golden shovel?

The timing was pretty good for Twin Cities residents. We had good travel conditions through most of the daylight hours. The rain didn’t mix with sleet and snow until late Saturday afternoon, then the wet snow arrived for the evening hours:

Be careful on the slippery roads!

I bet that you can’t wait to shovel this latest batch of flakes! This snow is much heavier than the fluffy snows that we saw last month.

Here’s a shoveling tip, from the NWS:

The big picture

The National Oceanic and Atmospheric Administration’s North American Mesoscale forecast model shows the potential precipitation pattern from Saturday evening through Sunday afternoon:

NOAA NAM simulated radar from Saturday evening through Sunday afternoon, via tropicaltidbits

The color chart to the right of the loop refers to the strength of the signal that returns to the radar, not to the amount of snow. Accumulating snow tapers off by around sunrise on Sunday in the Twin Cities metro area, but snow continues to the northeast.

How much snow?

Locations in western Minnesota are prime candidates for the golden shovel award for highest storm totals.

Holloway, in Swift county of west-central Minnesota, came in with a 12 inch snowfall total around 8 p.m. Saturday. We’ll see the final tally on Sunday.

Here’s the NWS depiction of potential storm totals:

NWS Twin Cities

 

Notice the double-digit snowfall totals in much of western Minnesota from this winter storm.

I expect snow totals by late Saturday night/early Sunday morning to range from about 7 or 8 inches in the far northwest corner of the Twin Cities metro area to 4 or 5 inches in the far southeast corner of the metro. Minneapolis and St. Paul look to be somewhere in the 5 to 6 inch range.

Warnings

As of Saturday evening, winter storm warnings continued for much of Minnesota and western Wisconsin for a combination of heavy snow, reduced visibilities and hazardous travel conditions:
