.DISCUSSION...
Issued at 258 AM CST Sun Dec 22 2024

An upper level wave will move into North Dakota today, the slide
southeast into southern Minnesota tonight. One effect of this system
will be turning surface winds from the south to the west, which
allows for a mild day with temperatures 5 to 10 degrees above
normal. The other effect will be the continued small chance for
mixed precipitation near highway 14 and then roughly near and east
of the Buffalo Ridge. Mid level forcing and moisture increases this
afternoon ahead of this system, but low level saturation remains a
challenge. Will maintain a roughly 10-20 percent chance in these
areas. Late this evening into the overnight hours the main vort lobe
drops into southwest Minnesota and brings a bit of lift and moisture
again, with the moisture a touch deeper, but still struggling in a
small corridor in the mid levels. Regardless, if precipitation can
develop amounts will be light with the main impacts likely limited
to slower travel times.

As this system passes cooler air will leak in from the north and
quite a few model soundings are pretty bullish on producing stratus
for the day Monday in many locations. This will likely limit highs
and have dropped them a couple of degrees across most of the area.
Once again the warmest readings will be across the Missouri River
Valley.

Monday night into Wednesday ridging aloft will build into the area
and bring dry and mild conditions. Highs Tuesday and Wednesday will
be 5 to 10 degrees above normal with lows on Wednesday morning about
just as mild.

Wednesday night into Thursday the models are a bit more aggressive in
drifting low pressure to the south northward which will bring a
mainly rain chance to the area. The better chances will be in
northwest IA and northeast NE. Mild conditions, especially overnight
lows, are expected with the broad southerly flow.

The models are generally bringing through the main trough Friday
into Saturday so there will be a continued chance for precipitation
and still mainly rain. The mild temperatures will also continue
through this time.

VFR through much of the period. A few flurries or patchy very
light mixed precipitation will be possible near highway 14 into
parts of southwest MN late this afternoon into tonight. Amounts
should remain very light. Otherwise, after about 6z MVFR and
possibly IFR ceilings will begin to develop from north to
south, likely reaching I-29 between 10-12z.
