...Synopsis...

Main 500 short wave and sfc moving quickly southeast into
southwest Wisconsin and northeast Iowa at 09z. There is a 500 mb
short wave trough axis extending north into the Red River valley
causing an additional area of light snow. This light snow area
moves gradually east today and weakens. In this light snow area
thru noon half inch of snow is likely in the Red River valley
10z to 16z period with potential for 1 inch. Winds are gusty in
the far southern valley with gusts 30 mph Wahpeton but farther
north gusts are gone with winds in the 15-20 mph range. With
blowing snow not an issue, did coord with BIS and DLH and we
dropped the winter weather advisory around 09z.

There will be additional short waves moving east and southeast
from southern and central Alberta thru Thursday night. Impacts
are mainly in regards to freezing rain potential not in our area
but from parts of Montana thru SW ND into SD. Light snow
periodic tonight thru Thursday night, with the Thursday night
light snow along an arctic cold front that will move through.

This front will bring a 2 day cold snap with wind chills likely
to drop to -30F and lower. 20 percent chance of wind chills -40F
and lower for a time Saturday morning.

500 mb flow goest more zonal quickly next week with temperatures
moderating. To what degree they moderate or rise to is uncertain
due to snowcover.
