..strong winds this evening through Sunday... 

Discussion...near record temperatures are expected today across 
southwest Montana into Lemhi County, Idaho. Todays high in Butte 
may just reach the record for the day of 80 degrees. 

A cold front is still expected to make its way through the region 
this evening into the overnight. Winds across the higher terrain 
could gusts over 45 mph while locations in the valleys will see 
gusts over 35 mph. There is some concern that stronger winds could 
be felt across the Bitterroot valley tonight but confidence is 
low. As the system pulls away from the area Sunday, winds will 
continue to be gusty. With regard to rainfall, a trace to several 
hundredths are expected in the valleys while up to 0.50" is 
possible in the higher terrain. Snow levels will fall to around 
7,000 feet by Sunday morning with only light amounts expected. 

Model guidance suggests that high pressure will slowly develop and 
intensify over the northern rockies from Monday through next 
weekend. Anticipate mostly dry conditions and near-record warm 
October daytime temperatures during this time. The pattern to come 
has more in common with August than October. Unfortunately, the 
dry and warm conditions will allow a resurgence of smoke from 
some of the remaining wildfires around the region. By the end of 
next weekend, models agree that a change in the pattern will come 
to pass, however the signal is fairly vague at this Point. Bottom 
line: the late Summer warmth cannot last forever and we lose 3-4 
minutes of daylight (warming) every day in the next week. 


Aviation...mountain wave activity will continue along and east of 
the Continental Divide. Meanwhile, expect breezy conditions to 
develop after 10/1800z at all the terminals. A strong cold front 
is expected to traverse across central Idaho between 11/0000z and 
11/0600z, and across western Montana after 11/0600z. Expect strong 
winds at ridge-top near 50 knots, with obscuration from rain and 
clouds. Surface winds with the front could gust to 40 knots at all 
terminals. On Sunday, winds will continue to be gusty while 
precipitation chances will decrease throughout the day. Strong 
winds will continue to be possible across higher valleys near the 
Continental Divide especially near kbtm, Avon, MacDonald Pass and 
along the I-90 corridor from Deer Lodge to Warm Springs.
