NWS ALERT (4) WINTER STORM WATCH
Interesting discovery on the 06Z GFS for central Wisconsin between midnight and 6AM tomorrow morning. Very strong spike in forcing through the snow growth zone. The result is 3"/hr snowfall rates resulting in 6" of accumulation by day break. THIS IS PROBABLY NOT GOING TO HAPPEN. No other site but KOSH showed this but I wonder what the GFS trying to tell us? I think t-storms moving in from the south, abruptly changing to frozen precipitation over central or southern Wisconsin. The interface between t-storms in the south, snow north, and tanking surface temps; could get real messy early Friday morning.
