.DISCUSSION...

Through Saturday...

Conditions trend warmer and drier into Tuesday as the area
remains situated under northwest flow aloft, with ridging to the
west, and upper troughing to the east. Occasional weak waves will
drop through the periphery of the area bringing isolated shower
and weak thunderstorm chances, mainly for east/northeast areas.
Breezy winds will be found over the east on Monday, with northwest
wind gusts of 20-40 mph expected, strongest near the Dakotas
border. Winds increase on Tuesday, ahead of a stronger shortwave
expected to drop into the region Tuesday night/Wednesday.
Westerly winds will be strongest over the western foothills
Tuesday, with lesser winds to the east. There are currently
moderate probabilities for wind gusts to 50 mph along the western
foothills. As the aforementioned wave and associated cold front
drop through the region Tuesday night/Wednesday, breezy northwest
winds are expected to spread over the entire area, strongest over
the far east and down along the east side of the Bighorns
(moderate chance of wind gusts to 50 mph). Wind highlites are not
anticipated for Tuesday or Wednesday at this time, though it is
something to monitor. Cooler conditions can be expected for
Wednesday behind the front, along with a better potential for
showers/thunderstorms (20-60% chance) into Wednesday night, mainly
for northern and eastern areas.

Occasional pieces of energy will continue to move through
northwest flow through the end of the work week, allowing
isolated afternoon/evening showers and thunderstorms to continue
(20% or less chance). Ensembles continue to indicate upper
troughing will move onto the West Coast Friday into Saturday, with
southwest flow developing over the northern Rockies. This would
bring a better potential for daily thunderstorms over the upcoming
weekend with shortwaves lifting into the region and plains
moisture advecting into the area.

High temperatures are forecast to range from the 70s to lower 80s
Monday, to the 80s Tuesday. Temperatures cool down to near normal
Wednesday through Saturday with highs in the 70s to near 80
degrees. STP

.AVIATION...

Scattered showers are expected to move into east central MT Monday
morning after 12Z. Gusty W to NW winds are also expected with
gusts 25-35 kts forecast across southeast MT and north central WY
Monday afternoon. TS
