.DISCUSSION...
Issued at 339 PM CST Sat Nov 22 2025

The remainder of the weekend looks quiet, with much above normal
temperatures. Surface ridge axis moves over the region this evening,
then shifts east into MN between 06Z and 12Z Sunday. At that time,
light southerly winds develop as well. South to southwest winds and
mostly sunny skies on Sunday will allow temps to warm rather nicely
as 925mb temps rise to between +10C and +15C by Sunday afternoon.
Temps look to rise into the mid/upper 50s, perhaps even low 60s
across portions of south central SD.

Will then be watching two separate areas of low pressure moving
eastward across the central/northern plains Monday into Tuesday.
First low on Monday looks to bring best chances (50-70%) for
rainfall to mainly southeast SD and into adjacent parts of northwest
IA and northeast NE. Further north, lesser chances around 30 percent
or less over east central and northeast SD. Precip amounts look
light, with most areas generally less than 0.25in.

Next wave of precipitation (in the form of snow) looks to affect
mainly northern SD into west central MN Tuesday into Tuesday night.
Models now latching onto a solution that looks to bring snowfall to
the area, something not seen 24 hours ago when the GFS was
considered an outlier. Current snowfall forecast does feature a
general 1 to perhaps 4 inches across northern SD into west central
MN, highest up on the Coteau in the higher elevations. Lesser
amounts across southeast SD into northwest IA and northeast NE from
a dusting to nothing at all. Will continue to monitor trends with
this system.

Still looking at colder air overspreading the region by the middle
and end of next week, with highs in the 20s and 30s while lows drop
into the single digits and teens. Still looking at a potential storm
system towards the very end of the 7-day forecast period as 20-30
percent chances creep in by Saturday. Still much to digest in
regards to storm track/intensity.
