.DISCUSSION...
Issued at 304 AM CDT Fri Sep 19 2025
Surface low centered over eastern South Dakota/southwestern
Minnesota will gradually churn northward today through tonight
along the Minnesota and Dakota borders. At which point, it will
begin to lift to the northeast. And even then, it will take
through the remainder of the weekend to fully enter southern
Ontario. This will result in continued scattered showers mainly
for the eastern half of the state through this morning, then the
eastern third this afternoon through Saturday. A few
thunderstorms are possible east as well. Low ceilings, along
with some patchy fog, is present this morning across most of
the state. Skies are expected to clear in western ND later this
morning through the afternoon hours, while fog should dissipate
by this afternoon.
Other than some lingering showers in the James River Valley on
Saturday, mostly dry conditions are expected Saturday through
the next workweek for western through central ND. The exception
remains that some models still bring shortwave energy through
Monday. Deterministically, this timing continues to slow down
and digs south quicker. As a result, NBM mentionable PoPs are
now focused mostly on the far southwest.
Highs today will remain mostly in the 60s before a lowly
amplified ridge passes through this weekend. Along with clearing
skies and surface flow becoming southerly on Sunday, this will
result in a gradual warming trend this weekend. Resulting highs
Saturday will mostly range from the mid 60s to low 70s, and the
70s to low 80s Sunday. Highs for the next workweek will be
near average to slightly above average. Currently, NBM
forecasts are mostly in the 70s with a low 25th/75th percentile
spread. Based on deterministic models, a ridge with questionable
amplification may pass through around midweek. Depending on
timing, duration, and amplification; a day or two could easily
wind up on the higher side of these temperature spreads.
Seasonable to seasonably warm lows in the 40s to low 50s are
also expected through the next workweek.

Issued at 1243 AM CDT Fri Sep 19 2025
Scattered showers persist across central and eastern ND, with a
few thunderstorms east of the James River Valley. Otherwise,
MVFR/IFR/LIFR ceilings are present across much of the state.
While showers are not expected to be as widespread from here on
out for western through central ND, these low ceilings are not
forecast to go anywhere for central and eastern parts of the
state through the period. The west, however, is likely to clear
out Friday morning or early afternoon. In addition, patchy fog
has developed over parts of central and eastern ND. While it`s
generally not favored to become dense, IFR visibility from fog
is still expected at times through Friday morning.
