.DISCUSSION...
Issued at 259 PM CDT Wed Oct 8 2025

Exiting high pressure will continue to bring breezy and mild
conditions through this evening. A weak and mainly dry surface
trough then moves through tonight, lessening the winds. These
lessening of winds combined with cooler temperatures in the 40s
could bring some patchy to areas of fog tonight into Thursday
morning, especially in the west and some central portions.
Another weak yet mainly dry wave then moves through on Thursday.
This could bring some cloud cover to the east, with mainly clear
conditions elsewhere. Temperatures will remain mild and in the
mid 60s to mid 70s. Surface high then moves through Thursday
night through Friday. Cooler temperatures may be found for
Friday morning, with lows in the 30s to lower 40s. Perhaps some
Freeze products will be needed if these temperatures trend
colder. Cooler highs in the 60s will then be found on Friday.
Some breezy southerly winds may then be found in the west as
this high pulls away later in the day Friday. These breezy winds
may then linger Friday night. Bringing more mild overnight lows
in the 40s to lower 50s. Mainly dry conditions are forecast to
continue.

An approaching trough will bring southwest flow aloft, with
breezy to perhaps windy southerly flow lingering at the surface.
The result will be warming temperatures on Saturday back into
the mid 60s to mid 70s for most areas, along with breezy winds.
A surface warm front could also be the focus for some showers
and perhaps a few thunderstorms Saturday afternoon through
Saturday night. Shear and instability still look limited, thus
the chances for severe weather remain very low. The main trough
and cold front then looks to move through sometime Saturday
night through the day Sunday. Along the initial passage of this
cold front cold be a few thunderstorms with chances for severe
weather looking very low. Breezy to perhaps windy conditions may
also be found with this front on Sunday. Front then moves east
and the upper low moves northward into Canada Sunday night.
Perhaps some lingering precipitation could be found in the north
Sunday night. If this precipitation lingers then perhaps some
snow may mix in with rain across the north. Most clusters now
showing this more northern shift to the upper level wave, making
chances for snow in North Dakota low this weekend. This
northern shift has also lowered QPF chances. The current NBM
chance for over an inch in 48 hours over the weekend is 5 to 20
percent with the higher chances coming in the north. Looking
ahead into next week, cooler yet more normal like temperatures
look to be in store. A general trough pattern could also linger
chances for precipitation at times. NBM mainly has rain chances
for now, although perhaps some snow may mix in if precipitation
chances shift to the cooler nights.
