Area Forecast Discussion
National Weather Service Missoula MT
222 PM MDT Mon Oct 12 2020
...Strong and Gusty Winds by Late Tuesday...
.DISCUSSION...Showers will continue to be replaced by gusty winds
as drier air moves in from the northwest. A wind and lake wind
advisory remain until 6 pm for parts of western Montana.
Another influx of moisture, supported by a strong upper level
jet, is expected to arrive Tuesday morning. Snow levels are
expected to rise with this next weather system, but accumulations
are possible Tuesday morning on Lost Trail and Lolo passes, but
daytime accumulations will mainly be limited to the highest
terrain and above 6000 feet in Glacier National Park. Moisture
will be abundant with Tuesday’s weather system, leading to
widespread rain. The Clearwater Mountains may end up with
2.00-3.00 inches of rain by late Tuesday.
Wind is also concerning with Tuesday’s shortwave trough and
cold front, based on wind anomalies which are at around maximum
for this time of the year. The high terrain is most likely to have
persistent gusty winds. Rain may inhibit the wind potential for
much of Tuesday in the valleys, making the forecast for the timing
of strongest valley winds less certain. The cold front passage
and unstable conditions behind the front may be the main focus for
valley winds, which is most likely to be late in day. Strong
winds may linger through Tuesday night and gusty winds are
expected through Wednesday. A high wind watch has been issued for
most of western Montana for Tuesday afternoon through Tuesday
night.
Snow above 5000 feet is possible through Wednesday, especially in
the Glacier Region, where a winter weather advisory has been
issued.
Thursday and Friday will start off chilly, followed by near
average high temperatures. Friday may become breezy, and shower
chances look to return to northwest Montana late in the day on
Friday.
&&
.AVIATION...A westerly pressure gradient and 110 knot upper level
jet will continue to support gusty westerly winds through 0100z
across the Northern Rockies. The strongest winds will continue
across southwest Montana and Lemhi County, ID where gusts up to 40
knots are possible. Ongoing shower activity will quickly diminish
after 0000z this evening.
A potent weather system will impact the Northern Rockies Tuesday.
An anomalously strong jet stream (140-145 knots) and deep
atmospheric moisture profile will support widespread precipitation
and gusty winds across area Tuesday. MVFR to IFR ceilings will be
commonplace across north central ID and western MT by 1500z
Tuesday. Low level wind shear will be a concern after 1800z
Tuesday, at all airfields, given ridgetop winds in excess of 60
knots.
