.DISCUSSION...
Issued at 335 AM CDT Wed Oct 8 2025


Currently a slight ridging pattern is over the western and
Northern Plains areas of the country. An upper level low and
trough are moving into the Pacific Northwest. At the surface
yesterday`s high pressure sits near Duluth, Minnesota. With the
influence of that high pressure still, most of the Northern
Plains are forecast to be cloudless today.

Today, the high pressure will move into Wisconsin, while a low
pressure in Alberta moves southeast. The pressure gradient
between these two systems will tighten over the Dakotas,
creating south winds gusting near 35 mph. These strong winds
will mainly be in the south, central, and James River valley
today. Breezy winds will then continue overnight until the
pressure gradient releases Thursday morning. High temperatures
will start a slight warming trend today with the ridge pattern.
Look for highs in the 60s and 70s today.

The ridge will start to amplify through the end of the week,
causing temperatures to warm mainly to the 70s. The far west has
a chance to see the upper 70s by Saturday when southwest flow
moves in. This southwest flow is a direct result in the
aforementioned low in the Pacific Northwest. By Friday night the
trough will be digging through California. Of course with this
southwest flow, chances for rain return and maybe even a
thunderstorm. This trough could also kickoff a Colorado Low
Saturday which would impact the Dakotas. Temperatures will be
far too warm for snow, so it could result in thunderstorms or
just widespread rain. So far, the highest QPF amounts look to be
in the northwest and along the northern part of the state.
Temperatures will cool back down to near or below average to
start next week on the backside of the low in the 50s and 60s.
The pattern could remain active as another low pressure system could
develop in the Pacific Northwest again early next week.
