246 PM MDT Sat Mar 28 2015


Gusty westerly winds will continue into early evening before
gradually diminishing with several areas under wind advisories.
Many locations will see gusts of 35-45 mph, while favored windy
areas such as the I-90 corridor from Deer Lodge to Drummond to
Butte will likely see slightly higher gusts at times. Chopping
conditions will also continue on Flathead Lake, where small boat
operators are urged to use caution.

Scattered shower activity with an isolated thunderstorm threat will
persist the rest of the afternoon, especially over northwest and
west central Montana. Areas passes may briefly experience moderate
snow showers, but nothing more than a light slush accumulation
will be possible. High pressure will bring a return to drier and
warmer weather Sunday into Monday, in fact high temperatures
Monday are expected to rise to well above normal.

Tuesday will bring the next vigorous Spring front. Showers,
possibly with embedded thunderstorms, will increase early from
west to east as the front pushes through, along with gusty winds.
Wind advisories, including for Flathead Lake, may be required
again for Tuesday. Snow levels will lower with showers lingering
Tuesday night, bringing potential for pass impacts. Cool and
unsettled weather will then continue through the remainder of the
week, as a complex weather system lingers over the northern


Aviation...the upper level wave that has been responsible for the
scattered rain and snow showers and breezy conditions over the
region will shift off to the east by tonight. Strong gusty winds
are expected to peak by 28/2200z and then diminish especially
after 29/0200z at all terminals. Expect drier and milder
conditions on Sunday and Monday as a ridge of high pressure builds
into the region.
