.DISCUSSION...
Issued at 130 AM CST Sun Nov 9 2025

Currently the Northern Plains are under northwest flow, with a
big ridge across the whole west coast. Very cold temperatures
are flowing into the region with this northwest flow. At the
surface, high pressure sits in the Northern Plains. This high
pressure is slowly eroding clouds across the region. Where the
clouds have cleared, temperatures are currently in the single
digits near zero! Patch fog has developed in the northwest where
5 inches of snow has fell. Now that snow is adding moisture to
the air.

Today the ridge in the western CONUS will slowly slide closer to
the state. So the western part of North Dakota will see highs in
the 30s, and the rest of the state will see the upper 20s with
sunshine warming the ground. In the north where snow is
currently on the ground, highs could be slightly cooler. Today
could also be breezy as the strong winds aloft will mix down.
This will actually be the case through Tuesday as winds could
gust near 30 mph each day.

Monday the ridge will flatten west of the Mississippi River.
This will bring warmer 850mb temperatures to the Northern
Plains. The Chinook winds across the Northern Rockies will bring
down these warmer temperatures and compressionaly heat them.
This will create high temperatures possibly in the 60s across
eastern Montana and western North Dakota this week. Mid to late
week the zonal flow turns into a ridge as a trough digs through
the western CONUS. As the flow turns to the southwest Friday,
slight (20%) chances for rain return Friday night, otherwise a
quiet weekend with slightly above average temperatures.

.AVIATION /06Z TAFS THROUGH 06Z MONDAY/...
Issued at 1200 AM CST Sun Nov 9 2025

Patchy fog may develop over northwest North Dakota with very
localized IFR visibility, otherwise VFR. This could affect the
KXWA terminal, but confidence in this happening is quite low so
will not mention in the TAF product. Then VFR conditions will
prevail.

.BIS WATCHES/WARNINGS/ADVISORIES...
