.SHORT TERM /THROUGH THURSDAY/...
Issued at 225 PM CST Wed Jan 22 2025

Accumulations so far today have been about an inch or less
across our area due to warm air advection. That has moved off to
the east and now the main upper level trough will arrive late
this afternoon into tonight. NAMNEST/HRRR indicates the light
snow increasing in coverage across much of the forecast area
through this evening. The snow will then diminish and end around
midnight. Additional accumulations of around an inch or less is
expected. Roadways remain partially covered with the salt
helping with temps in the 20s. There will be snow continuing for
the evening commute with visibility at times down to a mile.
Slippery spots are expected especially on untreated roads. The
amounts are minor but will issue a special weather statement
because of the snow falling during the evening rush. Lows
tonight will drop into the single digits nw to around 10 se.

With the passage of the trough this will bring somewhat colder
temperatures on Thursday, with highs in the mid to upper teens.
The good news is there will be mostly sunny skies.

.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
Issued at 225 PM CST Wed Jan 22 2025

Thursday night: This appears to be our last bitterly cold night
of the extended with lows in the single digits below and above zero.

Friday through Wednesday: Temperatures look to moderate on Friday
as southerly return flow helps usher in somewhat warmer air
into the 20s. The warm up should persist into Saturday, when we
should see widespread highs into the middle to upper 30s. A minor
cool-down on Sunday is expected before even warmer temperatures
move in early next week. The NBM indicates highs warming to the
upper 30s to mid 40s for Tuesday and Wednesday. With bare ground
these readings could be warmer.

We`re not seeing any notable chances of precipitation after tonight
in the extended, with only a weak mid-level impulse moving through
Friday night, which could generate some flurries, but the signal
for this is very weak due to a lack of moisture, so we should
largely remain dry through the middle of next week. The long
range models are hinting at a more active and snowy pattern the
first week of February. Time will tell.
