...QUICK ROUND OF STORMY WEATHER SATURDAY MORNING...WITH A LONGER
PERIOD OF WET AND COOL WEATHER NEXT WEEK...
Showers will continue to dissipate across western Montana this
afternoon and evening as a ridge of high pressure builds over the
Western US. Clearing skies tonight could allow for a few areas of
patchy fog to form in a some central Idaho and western Montana
Tomorrow looks to be quite warm as the ridge axis moves overhead,
with some locations possibly seeing their highest readings yet
this year. Missoula, for example, might see its first 70 degree
day of 2015 (50/50 chance according to an ensemble of forecast
models). A few showers or thunderstorms could pop up late in the
day over central Idaho as some ascent and moisture aloft move in
ahead of a deep trough pushing onshore into the Pacific Northwest.
This trough and associated surface cold front will sweep across
central Idaho and western Montana Friday night into Saturday
morning, bringing showers and a few thunderstorms, breezy winds,
and lowering snow levels. Those with outdoor plans should be
prepared for a big change from Friday`s weather. Some of the
higher passes such as Lolo and Lost Trail could see snowflakes by
Saturday afternoon, although accumulating snow is not expected
(although area ski resorts could pick up a few inches).
Sunday and Monday will be a fairly quiet day of weather as a brief
ridge of high pressure builds. Temperatures will be above normal
for this time of year with highs in the 60s on Monday. This ridge
will be short lived as wet spring weather returns on Tuesday.
Tuesday through Friday...
Moist westerly flow will keep the weather pattern active
throughout next week. A cold front is expected to pass through the
region on Tuesday and with it will be gusty winds and scattered
showers. As the front passes, snow levels will lower and mountain
passes could see light snow accumulation. Behind the cold front on
Tuesday, several more disturbances will keep the weather cool and
showery through rest of the week.
Area terminals will see improved flying conditions today, with locations
along the Continental Divide being the last to see improvements
with a few showers and obscured terrain into this evening. Patchy
fog is possible at KGPI late tonight into Thursday morning, with
an outside chance at KMSO. Clear skies and great flying conditions
are on tap for Friday.
