Area Forecast Discussion
National Weather Service Missoula MT
334 AM MDT Sat Oct 22 2016

.DISCUSSION...Rain is expected across western Montana and north-
central Idaho this morning. Although fog has been a concern for
this morning, breezy conditions have lessened that threat in the
larger valleys. There is still the chance for fog to develop
across far northwestern Montana through late this morning. Snow
levels will generally fall to near 6000 feet, but along the
Idaho/Montana Border they may briefly fall to around 5000 feet for
a short period this morning causing rain to mix or change to snow
at Lolo Pass with minimal impact. Though some clearing later
today will give way to partial sunshine for many areas, high
clouds are anticipated to stream in from the southwest by this
afternoon and evening. There could be patchy fog that develops
tonight, but it may be more concentrated along and near river

On Sunday and Monday temperatures will rise to above normal
readings(50s and 60s)for much of the region with a mixture of sun
and high clouds expected.

The next weather system is expected to move into the region Monday
night into Tuesday. Increasing clouds will give way to showers
with snow levels generally around 7000 feet. Beyond Tuesday,
forecast models are fairly out of sync with one another, lowering
forecast confidence. Therefore minimal changes were made to the
going forecast.


.AVIATION...Light to moderate rain will fall across north-central
Idaho into western Montana affecting KGPI and KMSO with reduced
visibility and lowered ceilings, especially between 22/0900z and
22/1500z. KBTM will see a period of rain and perhaps a mixture
with snow between 22/1000z and 22/1500z. Expect gradual clearing
through 23/0000z across the Northern Rockies. Other than possible
morning fog Sunday, conditions will be mostly dry with high clouds
