Latest from NWS Bismarck.
Issued at 303 AM CST Wed Dec 7 2022
Quasi-
zonal flow Thursday will produce slightly warmer
temperatures. Friday a
trough digs through The Rockies but
produces dry weather and temperatures close to average through
the period.
The bigger news is a possible system next Monday through
Wednesday. Models are starting to agree on a
Colorado Low moving
through The Northern Plains. The GEFS mostly all have the storm
for North Dakota at the 00z run, with the exception of 3 members,
showing the possibility of getting missed. Another area to see
the uncertainty is in the clusters. They have timing uncertainty
for when the collocated
upper level trough will move through. Very
breezy winds could be a factor for this system as the pressure
gradient for the surface low looks to be fairly tight during
period of the snow. The
CPC is also hinting at above
normal
precipitation over the next 6-10 days, showing the possibility of
this system to happen as well. The NBM has a 70-85 percent chance
of getting at least one inch across the forecast area, and a 40
percent chance of at least 6 inches centered over Bismarck.
Remember, this is 5-7 days out and a lot will most
likely change
day to day.
