Area Forecast Discussion

.DISCUSSION...Today begins a week of very mild autumn weather,
with little precipitation expected until Thursday, or Friday at
the latest. Temperatures are still expected to climb into the 70s
and low 80s for much of the week, followed by cooler nighttime
temperatures. It doesn`t appear that many locations will be
affected by frost during this time.

Wednesday: while expected to be dry and warm, there is a small
"back door" disturbance that will creep over the Divide during the
day. The only impact will be increased easterly winds into the
West Glacier/Essex corridor, which will eventually spill into
Kalispell and the surrounding vicinity. Some breezy east winds may
also develop through the Clearwater Junction area through East
Missoula.

As we transition to unstable southwest flow on Thursday, cloud
cover will begin to thicken as upper level moisture increases.
There will be a chance for weak thundershowers during the
afternoons on both Thursday and Friday, however if cloud cover
becomes too thick, not enough daytime heating may occur to allow
thundershowers to fully develop on Friday.

Either way, our nice week will be slipping away by this point,
with an approaching low pressure system on tap to affect the
weekend. There are still timing issues with this incoming system,
but be certain that most of the weekend will be wet, and about 10
to 20 degrees cooler than what we`ll see this week. If you`re
making plans, be prepared for cool and wet!

.AVIATION...High cirrus clouds over the region will be exiting the
area this afternoon with fair flying conditions expected for rest
of today. Winds will be mostly light and variable through
Tuesday. Patchy valley fog will also be possible tonight and will
be most pronounced near bodies of water.
