.DISCUSSION...

KEY MESSAGES:

-  Strong westerly winds this afternoon and evening with the
   passage of a dry cold front.

-  Rain and snow showers return this weekend, especially in the
   mountains. Thunderstorms are possible on Saturday afternoon.

Wind advisories remain in effect across western Montana through this evening.
Widespread gusts of 30 to 40 mph have already been observed. Peak wind
gusts are expected between noon and 6 PM this evening, with gusts between
40 and 50 mph becoming common. The Mission and Bitterroot Valleys,
along with the I-90 corridor from Deer Lodge to Butte and Montana 1
from Georgetown Lake to Anaconda, are at the highest risk for
these stronger gusts. Isolated gusts over 50 mph are possible.

Winds will decrease tonight and remain calmer through the rest of
the work week. Temperatures will continue to run a few degrees
above normal for this time of year.

The next storm system (trough) will move inland over the West
Coast by Saturday and Sunday. There is still significant
uncertainty in the forecast regarding how this system will
develop. On Saturday, southwesterly winds will create a favorable
environment for showers and thunderstorms. There is a 15 to 25
percent probability of enough atmospheric energy for thunderstorm
development between noon and 6 PM Saturday. Any storms that
develop could produce lightning, gusty winds, and small hail.

Regarding mountain snow, the path of the low pressure system will
determine if high-elevation areas see a light dusting or several
inches of snow by Sunday or Monday. Some forecast models suggest
the storm will interact with cold air pushing south from Canada,
which could result in a foot or more of snow for the mountains.

&&

.AVIATION...Expect strong winds this afternoon with the most
intense gusts occurring between noon and 6 PM MDT. Widespread
gusts between 35 to 45 mph (30-40 knots) are expected. Winds will
begin to diminish after 9 PM tonight (08/0300Z). VFR (mostly clear)
flying conditions are expected on Wednesday, with westerly winds
generally staying under 25 mph (20 knots).
