.DISCUSSION...

High pressure will be present over the Northern Rockies through
Tuesday evening. Anticipate warm and mostly dry conditions across
the region during this time. There is a low chance of rain showers
over the Continental Divide this afternoon, completely dissipating
after sunset. Otherwise, afternoon breezes will be the most
exciting weather through Tuesday evening.

Early Wednesday, a relatively dry cold front will move across the
Northern Rockies from the northwest, creating gusty winds across
the region. These gusty winds will continue throughout Wednesday
daytime, impacting the traveling public and area lake recreation
(particularly Flathead Lake). Gusts to 40 mph will be common for
much of western Montana low elevations on Wednesday. Southwest
Montana and Lemhi County Idaho will be watched closely, as the
cold front may intensify winds further than other areas.

Showers and thunderstorms will begin to develop behind the cold
front on Wednesday and continue through Thursday. Rain amounts
appear fairly low during this episode.

A low chance of showers and thunderstorms will continue through
early Memorial Day Weekend across the Northern Rockies, as a high
pressure ridge creeps inland from the Pacific Ocean. Model
guidance suggests that Memorial Day Weekend will have a small
threat of daily daytime showers and thunderstorms, however no
significant rain events are expected.

.AVIATION...

Aside from a few showers along the Continental Divide through
sunset, fair flying conditions will exist across the Northern
Rockies during the next 24 hours. Terrain obscurations will be
sparse, with most occurring along the Continental Divide.
Occasional wind gusts to 20 knots are anticipated near KBTM
through 23/0300Z.
