Early update to the evening forecast is out. Main adjustment was

moving southward from Central Canada, and should affect areas
mostly northeast of Havre after Midnight tonight. Some gusty
winds/brief heavy rainfall possible with the stronger storms.

For Monday, a few isolated thunderstorms are possible along the
front range of the Rockies and across the mountains of Central MT,
between Great Falls and Lewistown. Most of these storms will occur
in the afternoon hours on Monday.

Otherwise, the rest of the forecast looks on track. Brusda

.DISCUSSION...
/Issued 542 PM MDT Sun Aug 10 2025/

 - Meteorological Overview:

Northwesterly flow has replaced a slow moving upper level low
that had lingered over the area over the past few days, which will
help bring a drier and gradually warmer pattern to the area. For
the most part, expect mostly clear skies through the week, with
just a few isolated and brief afternoon and evening showers that
may be able to pop up here and there through Thursday. Shower
chances increase Thursday night and Friday as a trough crosses
through Alberta and Saskatchewan, but even these chances appear to
be on the low side at the moment.

- Forecast Confidence & Scenarios

Biggest area of uncertainty this week is from low end chances of a
shower or thunderstorm developing across some portion of the area.
While any shower or storm shouldt be overly impactful on a
societal scale, these showers could cause some minor issues for
those trying to harvest crops. As we head to Thursday and Friday
of this week, the trough mentioned above will push through and
likely bring some more organized showers, but right now there
remains some disagreement with respect to the depth and speed of
the trough, leading to less confidence in the showers it will
bring. Ludwig

.AVIATION...
11/06Z TAF Period

VFR conditions will prevail at all terminals during this TAF
Period. The primary concern for this TAF period is a wind shift
from southwesterly to northerly at the KCTB, KHVR, KGTF, KHLN,
and KLWT terminals in a north to south fashion beginning around
11/10Z for the KCTB and KHVR terminals and around 11/14Z for the
KGTF, KHLN, and KLWT terminals. Winds will shift from southerly to
northerly at the KEKS, KBZN, and KWYS terminals during the
duration of this TAF period. There is a 15% chance for showers and
thunderstorms at the KLWT terminal between 11/18Z and 12/00Z
There will be isolated instances of low-level wind shear across
North-central Montana between now and 11/12Z. -IG
