Tiny adjustments to snow map. 2-5" instead of 2-4" in narrow band roughly WI Dells to Green Bay. Trimmed back on southern fringe. Also moving start time earlier...bulk of event still this aft/evening.
updated snowfall amounts. Heaviest amts on axis through Green Bay. Some short range models have locally (very narrow zone of potential) higher than 4" but comfortable with 2-4" zone. 00z run wants to push main band further north into northeast WI. WE'LL SEE.
Small adjustments to snowfall predictions based on 12z run. More clarity in the north. Update as needed next 24 hours.
SAT 8:24 AM
Will see light snow develop Sunday aft lasting up to midnight with an organizing weak system. Highest impact will be across central WI. Was going to play it safe with 1-3" broad zone in eastern/southern WI however I felt enough confidence in 3 or 4" amts in narrow zone in central WI. All models agree on this aspect.
Confidence is LOW across northern Wisconsin. I put the entire region at 0-1". 00/06z models are inconsistent, I hope the 12z will be better. Some are snowier(EC), others much drier. I preferred the NAM over the EC which emphasizes the heaviest amts in central WI.
