Mild Sunday temps; winter storm warnings begin Sunday night for some areas

Winter storm update

We’ve been talking about a potential winter storm for days now.

A winter storm is still expected to hit much of southern Minnesota and parts of central Minnesota and Wisconsin Sunday night through Monday.

The latest computer model info shifted the heaviest snow band a bit to the south.

The Twin Cities metro could ride the northern edge of the heavy snow band, with double digit totals possible by Monday evening in Scott and Dakota counties of the south metro:

NWS Twin Cities

Winter storm warnings have been issued for Sunday night through Monday evening for the areas where the highest snow totals are expected:

Here are details of the winter storm warning that includes Scott and Dakota counties starting at 3 a.m. Monday and running through Monday evening:

URGENT – WINTER WEATHER MESSAGE

348 PM CST Sat Jan 20 2018

…MAJOR WINTER STORM NOW HIGHLY LIKELY MONDAY ACROSS
SOUTHERN/EASTERN MINNESOTA INTO WESTERN WISCONSIN…
…CONFIDENCE IN LOCATION OF TIGHT SNOWFALL GRADIENT IS STILL LOW
SO THE WATCH CONTINUES FOR THE METRO…

.The Winter Storm Watch has been upgraded to a Winter Storm
Warning late Sunday night through Monday evening for areas southeast
of a line from New Ulm, to Burnsville, to Rice Lake. A Winter
Storm Watch remains in effect just to the west from Redwood Falls
to the Twin Cities to Taylors Falls.

A strong storm system will bring an area of heavy snow across
south central and east central Minnesota into western Wisconsin
by early Monday morning. Snowfall totals of 8 to 15 inches are
likely by Monday evening. At this point, the heaviest snow will
fall across the warning area. There may only be light snow
accumulations northwest of that line, therefore any slight shift
in track could result in large snowfall forecast changes.

A wintry mix with a period of freezing rain is also possible
Monday morning from Albert Lea toward Eau Claire, resulting in
light ice accumulation. In addition, northeast winds between 20
to 30 mph, gusting to 35 or 40 mph will cause blowing and drifting
snow and whiteout conditions at times, especially in open
country. It is possible portions of the Winter Storm Warning will
need to be upgraded to a Blizzard Warning in later forecasts.

Be prepared for difficult driving conditions if you have travel
plans across central or southern Minnesota and western and
northern Wisconsin.

Updates

We’ll monitor changes in the forecast models and give you updates as we get closer to Sunday evening.

Updated weather information can be heard on the Minnesota Public Radio Network, and you can read about weather updates on the MPR News live weather blog.

Temperature trends

We hit at least 42 degrees at Minneapolis-St. Paul International Airport Saturday afternoon.

It was our third consecutive day with an official Twin Cities high temp in the 40s.

I bet that doesn’t happen very often in January!

Sunday highs will be mild, with 30s over most of Minnesota:

There will be some 20s in the far north.

Highs in the 20s spread southward on Monday:

Southeastern Minnesota could cling to some lower 30s.

Twin Cities metro area highs dip to the 20s for Tuesday and Wednesday, then return to the 30s for Thursday and Friday.

Our average Twin Cities high temp is 24 degrees this time of year.
