UPDATE TO AVIATION

.DISCUSSION...
Tonight through Thursday...Scattered showers and slightly below
normal afternoon temperatures will continue over the next few
days. The first disturbance will slide southeastward through the
region tonight...affecting the Rocky Mountain Front and mainly
areas across Southwest MT. Generally snow amounts in the valleys
will be less than an inch...with an inch or two possible in the
mountains. Gusty west winds will also continue this evening along
the divide...but winds should decrease by midnight. For
Wednesday...expect slightly below normal temperatures...as
precipitation gradually exits the region. The next system will
move into the region by late afternoon Thursday...with increasing
chances for rain and snow starting in the west by late morning and
moving out towards Lewistown by late afternoon Thursday. Brusda

Thursday night through Tuesday...Cool and unsettled pattern will
continue through the medium range. An upper ridge residing over the
area to start the period gets flattened as it moves east in response
to a splitting upper trof that moves across the Continental Divide
on Friday. The trof will drag a cold front across the area and
scattered snow showers will be fairly widespread. As the upper trof
quickly exits the area to the east on Saturday, the flow aloft
becomes zonal. Periodic pockets of short wave energy will move
across the area embedded within the flow aloft to keep mention of
isolated showers over the plains and periods of mountain snow
through the weekend. Model consensus begins to break down to start
the week. By Sunday night, the GFS backs the flow aloft and
increasingly brings moisture across the area. At the same time, cold
air begins to push south out of Canada setting up an overrunning
situation. The European solution is a bit different in that it
maintains an upper ridge over the west coast but also develops an
overrunning pattern as Pacific moisture moves within the northwest
flow aloft and overruns the cold airmass sliding south out of
Canada. Have increased pops Sunday night through Monday to get a
foot in the door but further model runs will be needed to clarify
timing and impacts. Temperatures will remain below seasonal averages.
