.DISCUSSION...

Area sensor and camera observations have shown a mix of rain and
snow overnight across the CWA with a cold frontal passage. This
has also come with gusty northwest winds with the Lake Wind
Advisory for Fort Peck Lake in effect through Noon Saturday.
Isolated wind gusts in excess of 58 mph have been observed over
the Little Rockies but will remain small in spatial scale and
short in duration, thus have held off on High Wind Warning
issuance, though those traveling along 191 south of Malta through
early Saturday morning should keep in mind the crosswind
potential.

Ensembles show a broad trough pattern remaining in place with a
new trough and closed low setting up across the Pacific NW by the
early to middle part of next week which will eventually shift
eastward. The bottom line is this will help maintain below average
temperatures across NE Montana over the next several days. Weak
shortwaves may produce isolated or widely scattered chances for
precipitation toward the middle of the week, though widespread
significant precipitation appears unlikely.

FORECAST CONFIDENCE & DEVIATIONS:

NBM held the line this forecast cycle except for minor adjustments
to near term pops to match trends and for collaboration. Near term
winds were also nudged upward over the Little Rockies which have
come in on the higher side of the guidance envelope. Looking
ahead, confidence increasing overall for a quiet start to the week
with below normal temperatures, though increasing ensemble spread
in the 500mb heights is noted by midweek.

.AVIATION...
LAST UPDATED: Saturday October 24, 2026 at 0430Z.

FLIGHT CAT RANGE: MVFR/IFR through Saturday morning, then VFR.

DISCUSSION: Lingering rain and snow showers with associated low
stratus will bring reductions in visibility at times as well.
Combined with the potential for patchy fog into early Saturday
morning, those flying should plan for MVFR/IFR to persist. After
18Z Saturday area terminals will see lingering low cloud shift
east and a return to VFR.

WIND: NW winds will continue at 15 to 25 kts, gusting to 35 kts
through 12z Saturday. Winds will then gradually diminish, keeping
west to northwest at 10 to 20 kts by Saturday afternoon.
