Area Forecast Discussion
National Weather Service Missoula MT
340 AM MDT Sun Oct 23 2016

.DISCUSSION...Dry and unseasonably warm conditions will continue
through Monday. Patchy areas of fog are possible this morning.

The next weather system is anticipated to arrive in western
Montana and central Idaho late Monday night into Tuesday morning.
Snow levels will initially start fairly high (around 8000 feet
lowering to around 7000 feet) due to warm southwest flow. This
will bring mainly rain showers to the region with little impact
expected other than to backcountry recreation. A cold front will
pass through the day on Tuesday, returning temperatures closer to
seasonal normals and creating breezy and showery conditions.

The next weather system will quickly approach by Wednesday
afternoon. Forecast models are showing this system as a quick
hitter as a high pressure ridge strengthens and pushes the
moisture north into Canada. Northwest Montana will stand the
greatest chance of precipitation Wednesday afternoon into early
Thursday morning. This appears to be a fairly warm airmass and
thus slightly above normal temperatures will be expected for mid
to late week.

Beyond Thursday, forecast models are out of sync in regards to
timing of weather systems. In either case, the weather pattern
appears to remain active with only short breaks in between


.AVIATION...Patches of valley fog will be possible through
23/1600z especially impacting areas near KGPI and KMSO. Otherwise,
VFR conditions are anticipated through Monday.
