LAST UPDATE : FEB 21, 2021

SAT 2/20 - 12:16PM - Updated snowfall forecast.


FRI 2/19 12:49AM - Down-trended snowfall amounts on this update. Kept 2-4" across northern IA into far western WI. Maybe that could be pulled into central WI? 12Z EC today was a little drier thus feel more comfortable with 1-2" wording, and in the end 1-3" may cover it best.


THU 2/18 9:20PM - added snowfall prediction map. Lowered forecast confidence. Range of ideas between models. I thought GFS/EC combo were pretty similar but will see how the overnight runs go. Expecting a low impact snow event with accums reaching 2-5" somewhere in southern WI. NAM is strongest/furthest north & I'm leaning away from it at this stage however everything still on the table IMO.

THU 2/18 8:30AM - a weak low pressure system will kick off snow for portions of Wisconsin, possibly all of WI depending on final track & placement. Southern WI is favored for the most accumulation. 2-4"? Monitoring the models and will update this forecast daily.
