Update on the upcoming winter storm. I’ll have a graphic available later. All of our counties are under a Winter Storm Watch from Sunday AM to Monday AM.
A few disclaimers before you read ahead:
-This highly depends on where exactly the freezing line sets up. North of there will see snow, south of there, a mix/ice/rain.
-Places that see more of a wintry mix will have lower snow totals.
-This will be a heavy, wet snow.
-Icing will most likely be an issue in northern Iowa.
-Snow/precip rates could be very heavy at times
– The following snow estimations are for southern Minnesota; icing estimations are for northern Iowa. Overall: 6-12″ will be possible in southern Minnesota by Monday morning; 3-6″ in northern Iowa; there is the possibility for a quarter to half inch of icing in north Iowa as well. There could be higher snowfall amounts especially north of I-90. These are the best estimates I have right now…still waiting for 12z data to come in.
Tonight: Precipitation will start after midnight. Rain/freezing rain/sleet will be likely in northern Iowa, with wet snow mixing in in southern Minnesota. Snow possible tonight: 1-2″. Icing possible tonight: Trace to .10″.
Sunday: Snow/sleet mix in southern Minnesota; wintry mix/freezing rain/rain in north Iowa. Precipitation could be heavy at times. There also could be a brief lull in the afternoon. Snow possible Sunday: 3-8″. Icing possible Sunday: Trace to .25″.
Sunday night: Snow in southern Minnesota; wintry mix/snow in north Iowa. Snow possible Sunday night: 2-4″.
