We’re riding the edge of snow in the Twin Cities. Wednesday’s light flakes were on the northern edge of a messy storm system crossing through Iowa. Friday’s weather maps looks likely to put the Twin Cities on the edge of the snow zone once again.

In the meantime, we plunge into subzero territory again across Minnesota overnight into Thursday morning. Lows will reach the minus 20s and minus 30s up north again and will approach minus 10 in the Twin Cities and much of southern Minnesota.

Friday snow chances

Friday still looks ripe for significant snow east of the Twin Cities across most of Wisconsin, but forecast model trends suggest moisture will be lacking with this system as it crosses Minnesota.

Trends suggest the Gulf moisture feed will only arrive and be injected into the system just as the storm glides right over the Twin Cities and eastern Minnesota around midday.

Check out the National Oceanic and Atmospheric Administration’s NAM 3 km model and see the trend. The forecast model loop below runs between 9 a.m. and 9 p.m. Friday.

NOAA’s Global Forecast System model is more bullish on snow for the Twin Cities and eastern Minnesota. It suggests moisture will reach the system sooner and produced several hours of vigorous snow across the Twin Cities and eastern Minnesota Friday.

For now NOAA’s Global Forecast System is the outlier. Most models suggest the western Twin Cities will get little snow, with heavier totals east into Wisconsin.

On the map below is NOAA’s latest digital model snowfall output. This will probably change as we move closer to Friday.

Friday’s snowfall forecast could go either higher or lower for the Twin Cities. But if you’re reading this in or traveling to Wisconsin, you have a higher chance of significantly plowable snow Friday.

Stay tuned.
