.DISCUSSION...
Through Saturday...

Ridging will continue to build over the Mountain West into the
new week. Little to no precipitation is forecast through Monday.
Look for high temperatures in the 40s to 60F today and Monday.

A building pressure gradient over eastern Montana, associated
with a surface low over southern Alberta, will bring breezy east
to southeast winds across the central and eastern Plains into
Tuesday. A developing upper low will begin to drop through Canada
on Tuesday as well. Ahead of this system, warm temperatures in the
60s and 70sF are forecast. Additionally, increasing pre-frontal
NW winds will spread across the western foothills Tuesday
afternoon. The latest guidance has the probability for at least 50
mph wind gusts along the US-191 corridor at 60-85%. For the
western plains, the probability for 50 mph gusts is 20 to 50%. The
latest probability for at least 60 mph gusts along the western
foothills is 40 to 60%. For Livingston, this would be more of a
hybrid event with diurnal mixing reaching the 40 knot westerlies
at 700mb.

Models are showing a cold front moving through Tuesday evening,
bringing another push of north-northwest winds across the area
into Wednesday. With the front, there is currently a moderate
chance of precipitation across southern MT and northern WY. There
is uncertainty on the extent of precipitation amounts though. The
mountains and eastern counties seem most likely to receive the
most moisture at this time. The aforementioned upper low will
slide through northeast Montana on Wednesday, bringing gusty to
strong northwest winds across the east as well as more
precipitation. The latest guidance has a moderate chance of wind
gusts greater than 50 mph for Custer, Fallon, and Carter Counties.

Something to note about Tuesday, the most recent event did not
bring much moisture for areas around and west of Billings. The
combination of gusty winds, warm temperatures, and low relative
humidities will result in increased grass fire concerns. Take care
not to cause a spark.

High temperatures are currently forecast to be in the 40s and
50sF for Wednesday. Ridging to zonal flow looks to return for the
latter part of the week, though a few weak waves could bring some
showers and unsettled conditions.

.AVIATION...

Weak cold front arrives today with winds turning east/northeast
at most sites by 18Z. Gusts to 20 kts are possible, particularly
at KLVM. A low cloud layer in the 2.5-5kft range may accompany
this front into the area, but at this time does not appear to
result in more than scattered coverage. BT
