.DISCUSSION...(This Evening Through Wednesday)
Issued at 1232 PM MST Wed Dec 3 2025

Light snow and flurries will come to end across the area as we
continue to progress into the late afternoon hours. Extensive
cloud cover will keep temperatures cold with very limited warming
occurring across the region today. A surface high pressure over
eastern South Dakota will allow for some clearing over the eastern
plains this evening and with the light winds forecast, overnight
lows will easily drop into the single digits. With this persistent
NW flow aloft expected to remain in place we can`t rule out
pockets of light snow developing across the Black Hills,
especially tomorrow afternoon when another fast moving shortwave
is progged to move through the area. This will help initiate those
areas of snow over the Black Hills. Adjacent valley locations may
see low end snow chances tomorrow afternoon and into the evening
with as this shortwave moves through. Minimal accumulations are
expected across both areas.

Heading into Friday and into the weekend, we will remain in the NW
flow aloft, but some marginal warmer air will have worked its way
into the northern Plains so temperatures are progged to slowly
modify on Friday but this will only get temperatures into the 40s
across the plains. As we progress into Friday night, another
shortwave will move through and bring light snow into the
forecast. The best chances for accumulating snow will be again,
across the Black Hills that will fall between Friday and Saturday
night. The long range forecast continues to show chances for
precipitation as shortwaves continue to move through.
