.DISCUSSION...

Today through Tuesday...

Fog is possible this morning, mainly over the creek and river
valleys of eastern Montana and north-central Wyoming (20 percent
chance). Any fog that does develop will dissipate through the
morning hours, giving way to a seasonable day with high
temperatures in the 40s and 50s (F) under mostly sunny skies.
Tonight, temperatures will drop into the 20s and 30s (F) with the
potential for fog over the plains of eastern Montana and north-
central Wyoming once again (20 percent chance).

Thursday will be a slightly warmer day with high temperatures in
the 50s to near 60 degrees (F). While mostly dry conditions will
prevail, a shortwave trough is expected to pass through the region
late Thursday into early Friday, bringing a slight chance of
precipitation to south-central Montana (15 to 30 percent chance).
With this, precipitation type is expected to be rain over the
lower elevations and snow in the mountains. Ahead of this
shortwave trough, breezy winds may also develop around Livingston
to Nye Thursday morning, with gusts in the 20s and 30s (mph)
forecast.

A ridge of high pressure looks to return Friday into Saturday
ahead of another potential weather system passing to the north
late Sunday into Monday. Ahead of this system, winds are expected
to increase Friday into Sunday over the mountains and foothills of
south-central Montana, strongest around Livingston to Nye through
Big Timber and Harlowton. While the conditions look most
favorable for Big Timber to Harlowton Friday into Saturday, the
most favorable conditions around Livingston to Nye are likely to
occur late Saturday into Sunday. With this, periods of wind gusts
in the 20s to 40s (mph) look to be common, with occasional gusts
to 50 mph around Livingston to Nye Sunday morning. As far as the
chance of seeing a 60+ mph gust goes, the chance is 25 percent
around Livingston to Nye Sunday morning.

Ensembles suggest warm and mainly dry conditions will take hold
next week under a ridge of high pressure aloft. LA


.AVIATION...

Patchy fog is forecast early this morning over portions of
eastern Montana and north-central Wyoming. With this, impacts to
KBIL, KSHR, KLVM, and KMLS cannot be ruled out, though confidence
is low at KBIL, KSHR, and KLVM, and moderate at KMLS. Any patchy
fog that does develop will dissipate after 15Z. Otherwise, VFR
conditions will prevail through the forecast period. LA
