2/19/11 Winter Storm update

February 19, 2011 3 Comments

Latest Watches/Warnings as of Saturday, 2:30pm.

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. ┬áThere 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″.

Stay tuned.

    OK, it’s 7:17 AM, where’s this snowstorm?

  2. Sue says:

    It should be interesting to see what happens. Weather forcasters in The Cities have us in the 2-5 inch range.

  3. Steph says:

    Yes, I agree. It’s a more complicated forecast for our area because of the amount of warm air. Sleet, freezing rain eats away at your snowfall totals. We could very well end up with 2-5.”
