evening but will diminish overnight. Skies should clear out from
west to east bringing frost potential to the region overnight.
As such, no major changes to this forecast update in terms of
impacts.

.DISCUSSION...
Issued at 326 PM CDT Sat Sep 6 2025
...Synopsis...
Northwest flow continues today into Sunday before becoming more
zonal heading into Monday. Shortwave ridging develops to the west,
then moves eastward into the Northern Plains late Monday into
Tuesday, bringing limited return flow ahead of a thermal boundary.
This could bring showers and thunderstorms into parts of the area
Monday evening through early Tuesday morning. A strong storm or two
is possible, however, widespread severe storms are not supported.
Wednesday looks to remain dry and warm as the ridge axis traverses
the area. Southwest H5 flow develops heading into Thursday, allowing
another mention of showers and thunderstorms late Wednesday night
through the weekend. Ensembles support enough instability to bring a
mention of strong thunderstorms into the forecast; however,
confidence is too low at this time to know the exact details and
timing.
...Frost Possible Tonight into Sunday Morning...
Cloud cover will gradually clear this evening and overnight, with
good support for favorable radiative cooling across much of the
area. Lows could fall into the lower 30s in the cooler spots;
however, many areas will likely see mid to upper 30s with light
winds. As such, there should be decent support for widespread frost
potential across much of eastern North Dakota and northwest
Minnesota. A frost advisory will be in effect starting at 2am Sunday
and will go through 8am Sunday.

.AVIATION /06Z TAFS THROUGH 06Z MONDAY/...
Issued at 1137 PM CDT Sat Sep 6 2025
VFR conditions will persist for the TAF period. Light and
variable winds will become southwesterly after sunrise but
should generally remain sustained between 7 and 12 knots, with
15 knots sustained the reasonable worst case scenario. Winds
will become light and variable once again after sunset.
