Things are about to get pretty messy around these parts. Capital Weather Gang’s Wes Junker has the details on a complicated storm expected to affect us for much of the day Sunday. What falls from the sky will depend on your location and surface temperature. Lots of uncertainty is still left with this forecast, but for now, these words from Junker are the best advice in advance of the storm: “The key message remains one of paying attention to your temperatures. If it is raining and the temperature is below freezing, play it safe and only drive if your travel is essential”

Through tonight: Cloud cover will increase overnight, ultimately leaving us with mostly cloudy skies after midnight. We’re not expecting any precipitation during this period save for maybe some snow flurries toward morning. Temperatures won’t be nearly as cold as last night. Overnight lows will generally range from 28 to 31 degrees with a light south wind at 5 to 10 mph.

Tomorrow (Sunday): A complex forecast to say the least. Precipitation will overspread the area from south to north from 10 a.m. onward. Inside the Beltway, a brief period of snow may accompany the precipitation onset, but a changeover to sleet/rain should happen rather quickly. High temperatures will hover in the mid-30s in the city, although a few slick spots on untreated roads and sidewalks are still possible, given that the ground and air temperatures will be only a few degrees above freezing at best.

Outside of the Beltway, specifically in areas to the north and west of the city, cold air could hang on at the surface longer, creating a period of freezing rain and slick conditions through the afternoon. A changeover to rain is expected for everyone sometime after 4 p.m. Some of the rain could be heavy at times in areas to the south and east of the city. All precipitation should be clear of the area by 10 p.m.

Lows tomorrow night will fall into the upper 20s to around 30 degrees, with increasing winds (10 to 20 mph) out of the northwest.

Super Bowl Freeze: Sunday’s NFL championship will be the coldest Super Bowl in the 52 year history of the game. Yes, the game will be played inside the domed U.S. Bank Stadium in Minneapolis. But outside, it will be downright frigid.

In addition to some light snow expected to fall overnight tonight, the Twin Cities will be brutally cold Sunday. How does 3 degrees with a wind chill of minus-11 sound? That’s the type of weather fans can expect to encounter as they head into the stadium for the game. It’s fair to say that the fans of the losing team will have to face the sting of defeat along with the sting of the bitter cold hitting their skin as they leave the game. Perhaps we shouldn’t have cold-weather cities host Super Bowls anymore? Just a thought.
