JAN 26, 2021 | Winter Storm Ending - up to 8" in Southern WI

LAST UPDATE : JAN 26, 2021

MON 11:48PM - FORECAST GOING WELL. Fixed grammar issues on previous update below.

MON 2:05PM - Latest trends are pulling back slightly on northern trend, lower snow amts in southern WI. Not too much changed from yesterdays snowfall prediction but did trim it down. I think dry air is going to be an issue on the northern edge of this system. May very well see a band of 5-7" in eastern IA/northern IL. Because that area is outside of WI, I'm going play the conservative side w/ 3-6" throughout the region. Heaviest accums will be across SW Iowa, E Neb.

SUN 10:18PM - A winter storm will track through the region Monday night into Tuesday morning. Over the past several runs a northward trend has been observed so confidence remains low on exact placement, however in a regional sense this appears to be a southern WI/northern IL snowfall event.

I'm using a 1-3" zone south of a La Crosse/Manitowoc line. 3-6" generally south of Madison. Based on 10-1 ratio. While Kuchera ratios show higher amounts...not willing to chase those yet. CONSERVATIVE. I stuck closer to the 12z EC in amts/placement. 00z(most recent) GFS/NAM/GDPS were further north. If this trend continues will need to increase amts.

The best potential for 6"+ still appears to be across Iowa and northern Illinois. Did not feel confident enough to add a intermediate zone between 3-6/6-12 yet. Some models are much snowier across Iowa than my map indicates.

Will wait for another model run and hope for more confidence.

Wow. Models NEVER showed the heavy snow band THAT far north. Surprising. Just when you think you've got it all figured out.
Heavy snow band pushed further north than expected overnight bringing 3-6"+ as far north as Fond du Lac County. Sharp cut off in snow amts just north of that. Snow totals underperforming near and south of the WI/IL border. Still snowing in southern WI.
