Area Forecast Discussion

.DISCUSSION...Another day of sunshine mixed with high clouds is in
store today. Throughout the night, patchy fog has been sloshing in
and out of some select valley locations (namely the Missoula and
northern Flathead valley), but should begin to lift by mid
morning. Temperatures will stay fairly mild, though temperature
inversions will be present, keeping mid and upper slopes warmer
than valleys.

Moisture will begin to move into the region during the end of the
week as the ridge moves east and southwesterly flow develops. Snow
levels are forecast to be high during the onset of precipitation,
so this means rain will fall up to an elevation of around
6500-7000 feet. The next trough and cold front have agreement
among model guidance to pass during Saturday. Snow levels will
then lower with the cold front, when rain will transition to snow.
Valley and mountain snow chances will extend into Sunday.

Model guidance continue to show the possibility of a relatively
warm and wet weather system to end the weekend and start the
coming week. Snow levels will again rise to above most mountain
passes in Idaho and western Montana. Most of the precipitation
with this next system has the best chance to fall through north
central Idaho and into northwest Montana.

.AVIATION...Fog is expanding into many of the valleys of north
central Idaho and western Montana, including the northern
Flathead Valley and Missoula valley. There are indications on
forecast soundings that this fog could create aviation impacts
through at least this morning and possibly into the afternoon in
valley of northwest Montana including KGPI. The rest of the region
will see passing high cloud cover and a lowering cloud deck in
northwest Montana this evening, followed by north central Idaho
and western Montana tonight. This cloud cover should keep many of
the valleys of the region from developing fog on Thursday morning.
