...WIDESPREAD WINDY CONDITIONS FOR NORTHERN ROCKIES SATURDAY...

.DISCUSSION...Most of the morning fog and low stratus has lifted
from select valleys, allowing for plenty of afternoon sunshine
and warming temperatures. Most locations will see very mild temps
today, but the nice spring weather will be rather short-lived as
our next potent cold front enters from the west later tonight. In
advance of this frontal passage, there is the chance for some
lightning to occur across western portions of Clearwater and Idaho
counties later this evening, with a few isolated storms possible
in the Panhandle and into NW Montana as well.

By Saturday morning, the brunt of the cold front will be felt
across the remainder of the Northern Rockies, as mountain snowfall
and valley rain becomes widespread. More notably will be the
persistent gusty winds expected for all of central Idaho and
western Montana, which will begin quite early and last through
Saturday evening. Wind advisories have been issued for parts of
southwest Montana and west central Montana to account for gusts up
to 40 mph; even some brief periods of gusts to 50 mph. In
addition, Flathead Lake is in a lake wind advisory to cover gusty
winds and resultant increased wave activity, thus impacting those
with boating plans. Strong winds will die off around sunset
Saturday, with Sunday looking drier, cooler, and less windy.

The next weather system on tap for our region will arrive
Tuesday, with impacts possibly lasting through Friday. Right now,
it looks to be a cooler and wetter system, so a dreary-looking
week may be ahead of us.

.AVIATION...A few cumulus buildups are possible over central Idaho
and far western Montana late this afternoon and evening ahead of a
weather disturbance moving into the region. This disturbance will
push a vigorous cold front through the area overnight and early
Saturday morning, with an abrupt shift to gusty westerly winds and
rain showers accompanying the front. Area terminals will likely see
sustained winds of 10-20 kts and gusts of 30 kts or more, with
the strongest winds at KBTM.
