.DISCUSSION...
Issued at 326 AM CDT Sun Sep 28 2025
An extended period of quiet, warm weather continues with mostly
sunny skies and dry conditions on tap for today. Highs are
expected to reach the 80s across most of the state, with the
warmest temperatures in the southwest as an east CONUS upper
high advects warmer air over the Western Plains. Through
Wednesday, this upper high will gradually amplify into a ridge
centered over the Great Lakes Region allowing warmer
temperatures aloft to persist over the Northern Plains. As such,
and combined with frequent southerly flow at the surface, highs
are forecast to reach the 80s across the state most days this
week through Thursday. Still, some upper 70 degree readings are
possible at times, especially near the Canadian border on
Monday.
For the most part, this pattern will maintain mostly dry
conditions through Thursday night. However, multiple weak
shortwaves may ride the western periphery of the ridge during
the workweek. As a result, the NBM continues to produce very
low, mostly non-mentionable PoPs over the forecast area. Still,
wouldn`t be surprised if a few showers, possibly with a few
rumbles of thunder, occur at some point.
Towards the end of the week, a major change in the weather pattern
is favored as models consistently suggest a trough will dig
into the western CONUS and break down the aforementioned ridge.
As this happens, rain chances will return to the area.
Where/when exactly, how much potential precipitation, and
duration of potential precipitation all remain open questions.
What maintains a higher probability, however, is a return to
seasonable temperatures that have the potential to become below
average by the end of the next weekend.

Issued at 627 AM CDT Sun Sep 28 2025
VFR ceilings and visibility are generally expected through the
period, though models hint that patchy fog may develop late
tonight in southwestern and south central parts of the state. LLWS
is likely occurring early this morning in parts of the southeast,
including at the KJMS terminal. Any LLWS should end by
mid-morning as surface winds increase while winds aloft
simultaneously diminish.
