.DISCUSSION...
Issued at 1214 PM CST Sun Feb 22 2026

Rest of today into tomorrow... Northerly flow peaks, with
tonight being the coldest part of the week ahead. Tomorrow, this
flow will start to shift allowing some warming. Not much
warming, but snow free areas in the south could make a run at 30
degrees. Much of the lower atmosphere today continues to be in
the DGZ such that any low clouds could and have led to period of
flurries. With there being little depth to this moisture
profile and the lack of any significant forcing, no accumulation
is expected. Tomorrow temperatures look to warm enough such
that any low level saturation will likely be out of the DGZ and
flurries are less likely.

Tuesday... A clipper will move out of Canada and into the Great
Lakes on Tuesday. The global deterministic models and ensemble
means keep the low to our north with the heaviest snow more
across northern Minnesota into northern Wisconsin. This has been
a common clipper track, especially this year, and like the
other times it has occurred snow is expected along and north of
I-94. QPF amounts are the main limiting factor as this moves
though quickly and the best forcing stays to the north. So under
a half inch expected with up to around an inch in and around
Rusk County, WI as they are closer to the low track. With this
low staying to our north we look to get a brief push of WAA on
Tuesday. This will bring temperatures up into the 30s with some
40s possible in snow free areas of southern and western
Minnesota.

Wednesday and Thursday... The brief push of WAA ends quickly as
Tuesday`s clipper moves out and brings back northerly winds
behind it. This will bring below normal temperatures back on
Wednesday. The roller coaster of temperatures continues
Thursday as temperature warm back above normal with westerly
flow. The temperatures shift is the more confident part of this
forecast as ensemble guidance keeps us consistently on the cold
north side of the next system. What is less certain is how far
south this tracks. This continues to appear the stronger of the
two systems, it is just less certain if the QPF will be over us
or stay mostly to the south. Regardless of the ensemble tracks
the best chances are across southern Minnesota and precipitation
type is certainly snow. Previous discussions have brought up the
AIFS, which continues to favor the more southerly track with
only southwest Minnesota seeing much of anything due to the low
track. Some members of the broader ENS and GEFS due keep this
track farther north. One of the more high end forecasts is the
deterministic GFS which has the Iowa/Minnesota border as the
central axis of precipitation. So this is all a long way to say
there remains a lot of spread between southern Minnesota getting
winter storm level snow level snow to a light less than an inch
event.

Rest of the week... Temperatures look to peak on Friday with
widespread 40s and maybe a few 50s over snow free areas as the
warmer westerly flow continues. This all comes to an end Friday
night into the weekend as northerly flow returns and below
normal temperatures are forecast for next weekend. This
temperature roller coaster is typical of the late winter as we
start to make the transition into spring. So expect more
alternating periods of cold and warm as we head into March.
