Our average Twin Cities high temperature is only 40 degrees on March 13. Parts of the metro area could touch 60 this Saturday afternoon. That’s our average Twin Cities high on April 19. There may be some flip-flop sightings Saturday afternoon….maybe even a few people enjoying ice-cream cones as they take their walk.

Saturday highs will be mainly in the 50s across the remainder of Minnesota and western Wisconsin, with a few 40s in far northeastern Minnesota.

Sunday highs will be mainly in the 40s, with the Twin Cities metro area and parts of southeastern Minnesota touching 50 degrees:

Northeastern Minnesota may top out in the 30s.

Winds pick up on Sunday, with gusts of 20 to 25 mph in many areas:

Plotted gusts are in knots, with 20 knots equal to 23 mph. Wind gusts could approach 30 mph Sunday afternoon in southwestern Minnesota.

Back to temperatures, Twin Cities metro area highs are projected to reach 40 degrees on Monday, followed by lower 40s Tuesday and upper 40s Wednesday through Friday.

Snow returns Sunday night and lingers into Monday

A strong low pressure system is bringing heavy snow to portions of Colorado today. That low pressure system could spread showers into southwestern Minnesota Sunday evening, then the showers turn to snow Sunday night as the precipitation spreads northeastward. There’s the potential for heavy snow in portions of southern Minnesota late Sunday night and Monday.

The National Oceanic and Atmospheric Administration’s North American Mesoscale (NAM) forecast model shows the potential precipitation pattern for Sunday evening through Monday afternoon: 

A winter storm watch starts at 10 p.m. Sunday in southwestern Minnesota and continues until 1 p.m. Monday. South-central Minnesota has a winter storm watch that starts at 1 a.m. Monday and continues until 4 p.m. Monday:

Here are details of the winter storm watch:

The same low pressure system that will bring snow to southern Minnesota late Sunday night and Monday is expected to dump very heavy snow on parts of Colorado, southern Wyoming, southwestern South Dakota and western Nebraska this weekend.

Parts of Colorado will see 18 to 30 inches of new snow this weekend. Here are the forecast snow amounts in Colorado:

Winter storm warnings cover much of that area:

Here are Colorado winter storm warning details:

URGENT - WINTER WEATHER MESSAGE National Weather Service Denver CO 420 AM MST Sat Mar 13 2021 ...POWERFUL WINTER STORM ON TRACK FOR THIS WEEKEND... .A significant late season winter storm now across Utah and Arizona will move to near the Four Corners region by midday today, and then track east/northeast across southeast Colorado Sunday. This track will bring significant snowfall to much of northeast and north central Colorado, and likely result in difficult if not impossible travel from late Saturday afternoon or evening through Sunday and Sunday night. The most severe conditions from deep accumulating snow will likely occur in and near the Front Range Mountains and Foothills where 2 to 4 feet of snow may fall, and along the I-25 Urban Corridor where up to 2 feet of snow can be expected. The favored locations for the heaviest snow totals along the I-25 Corridor will be from Boulder north through the Fort Collins area. Temperatures will be warm enough to bring a mix of rain and snow to areas east of a Fort Morgan to Limon line today into Saturday evening, but temperatures should turn cold enough there Saturday night into Sunday for mostly snow. Winds are also expected to increase by Sunday, with blowing and drifting snow possible across the plains.
