The sky is looking a bit strange this morning in the Twin Cities:

Ice particles in the air may be combining with a bit of smoke (aloft) from Colorado wildfires to bring us the interesting hues. Here’s a mention of the morning sky by the National Weather Service, along with the mid-morning radar loop:

The Twin Cities metro area will see a mix of sleet, rain showers, drizzle and snowflakes this Thursday afternoon and evening. A bit of thunder and spotty light freezing drizzle is also possible. Heavy snow will continue to fall in parts of central and northern Minnesota:

The pink-shaded area from west-central Minnesota up to Duluth will see the most snow, and that area is in a winter storm warning. The blue-shaded counties are in winter weather advisories this Thursday afternoon and evening.

Here are details of the Brainerd and Duluth portion of the winter storm warning:

A strong winter storm continues over the Upper Midwest. A strong area of low pressure over eastern Colorado this morning will lift northeastward through northern Illinois and southeast Wisconsin to northern Lower Michigan by early Friday morning. The forecast generally remains on track, with the potential for a swath of accumulations between 5 to 8 inches from the Brainerd Lakes region towards the Twin Ports.

Some uncertainty remains on the southern edge of the forecast snowfall swath as there will be a transition to a wintry mix or all rain the further southeast you go, so there is the potential for a shift in the location of the heavier snowfall. Some sleet or freezing rain may mix in with the snow at times at this transition zone over portions of northwest Wisconsin.

Additionally, there may be relatively little snow accumulations along the shoreline of Lake Superior as the lake is still relatively warm, so there may be a tight gradient in snowfall amounts along the North Shore to the higher elevations.

Weekend snow outlook

Forecast models show a batch of snow spreading across central and southern Minnesota plus western Wisconsin as we go through Saturday afternoon and Saturday night. The snow lingers through much of Sunday.

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

We can give detailed snow totals as we get closer to the weekend, but at this point I’d say that most areas that see weekend snow will receive enough snow to shovel.

Weekend temps

Our average Twin Cities high temp is 54 degrees on Oct. 24. The metro area will probably top out in the lower 30s this Saturday. Highs will range from the 20s in western Minnesota to 30s in eastern Minnesota on Saturday:

High temps on Sunday will also be very cold, with lower 30s again in the metro area:
