.DISCUSSION...
Issued at 222 AM CST Thu Dec 25 2025

Fog, dense at times with visibility a quarter mile or less, is
expected through this morning. LLM and fog will spread east today as
winds shift to the south and southeast. Latest soundings continue to
show less than 1km of moisture across the east through this
afternoon, so left drizzle mention out for now. There is an increase
in the column this evening when mid level moisture pokes into
northeast SD and west central MN, but temperatures will likely be
warm enough at that time to keep any drizzle from freezing. Highs
today rise above normal under the building upper ridge. This ridge
transitions east tonight. Highs in the mid 30s to lower 60s
(northeast to southwest gradient) today will be slightly cooler on
Friday as the ridge exits.

In the meantime, the dense freezing fog will be enough to accrete on
roads and make for slippery, hazardous travel through mid morning
when temps begin to rise with increased breeziness. Fog redevelops
tonight into Friday morning before scouring out by noon.

The next system moves through the Plains this weekend with a
trailing upper trough and sfc high moving in on Sunday. <25% chance
of precip as the front moves through. Significant cold air advection
will see temperatures drop below normal and winds increase with
gusts up to 45 mph on Sunday. Highs on Sunday may only be in the
teens. The gusty winds will also ramp up grassland fire danger,
though RH is expected to remain above 40 percent.
