What forecasters said that day
The local office's own words before this winter storm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Missoula, MT wrote its last area forecast discussion before this winter storm warning went out at Feb 23, 7:53 AM MST, 5 hours 52 minutes earlier.
Area forecast discussion, Feb 23, 7:53 AM MST, 5 hours 52 minutes before
Area Forecast Discussion
National Weather Service Missoula MT
753 AM MST Sat Feb 23 2019
.UPDATE...ISSUED WINTER WEATHER ADVISORY FOR PARTS OF NW MT.
&&
.DISCUSSION...Snow recently intensified at KGPI and infrared
satellite imagery shows a band of rapidly cooling cloud tops over
northwest Montana with rapid pressure rises (10 hPa per 3 hrs)
east of the Continental Divide. This all supports faster timing
and a somewhat more intense arrival of the arctic front for
northwest Montana, so we issued an advisory.
This will come in with three phases. The first will be moderate
snow covering roads followed by a blast of cold air causing
blowing snow generally around noon. As the temperatures fall snow
impacts will decrease but wind chills 10 to 20 degrees below zero
will be a concern until tomorrow.
&&
.AVIATION...Snow will be present at times across the Northern
Rockies air space during the next 24 hours. Strong westerly flow
aloft will prevent much of the snow from reaching valley floors
for very long, however instances of reduced ceiling and visibility
will be found at KGPI, KMSO, and KSMN throughout today. Another
rush of cold air from east of the Continental Divide will arrive
at KGPI near 23/1700Z, with northeast winds gusting to 25 knots
combined with intermittent snow thereafter through sunset. Terrain
obscurations will be common, particularly near KMSO southward,
where the bulk of snow activity will be occurring during the next
few days.
&&
.PREV DISCUSSION... /ISSUED 422 AM MST Sat Feb 23 2019/
..EXTENDED PERIOD OF SNOW ACCUMULATION ACROSS THE NORTHERN
ROCKIES TODAY THROUGH TUESDAY...
DISCUSSION...
Strong and relatively moist westerly flow aloft will present over
the Northern Rockies through the next several days, with varying
snow expectations over time. The westerly flow today will inhibit
a lot of the snow from reaching valley floors, however quick
bursts of snow will overcome the westerly (downsloping) winds at
times. Snow accumulations will be most pronounced today over high
terrain, with mountain passes experiencing highly variable road
and weather conditions throughout today and tonight. Also, another
gusty blast of cold air from east of the Continental Divide is
anticipated to reach Kalispell later this morning and spread
throughout western Montana through midday Sunday.
The pattern shifts a bit over the Northern Rockies Sunday
afternoon through Monday afternoon, with a slight warm front look
to the flow aloft. This pattern shift is expected to bring high
elevation snow measured in excess of a foot over the Clearwater
Mountains and along the Bitterroot Crest (on the Montana-Idaho
border). Lower elevations of north central Idaho, including the
Camas Prairie, will see snow accumulation in the 4 to 8 inch
range. Expect some difficult driving conditions over mountain
passes, including low visibility, snow, and blowing snow. The
relatively warm, moist flow over the impinging cold easterly winds
within area valleys of western Montana will yield some
interesting results, with a mix of periodic snowfall and some
blowing snow. Accumulations in the 4 to 8 inch range appear
likely for low elevations along and south of the I-90 corridor in
western Montana, while far northwest Montana (including
Kalispell) is anticipated to have accumulation of up to around 1
inch. All in all, the combination of snow accumulation, blowing
snow, low visibility, and poor traction will create a sustained
travel impact through Monday afternoon.
Tuesday will see a coastal trough deepen into a defined low
pressure circulation off the west coast. Moisture will continue
to be pushed inland, however the cold airmass in-place will begin
to retreat eastward. Tuesday could see widespread 4 to 8” snow
amounts in the valleys of Central Idaho and West Central Montana
with up to 20” in the Bitterroot mountains from Southwest of
Missoula up to west of St Regis. Northwest Montana will see
amounts of 2 to 4".
After Tuesday, there will be a slow warming trend although
surprise surprise, we will most likely not return to seasonally
normal temperatures. There are hints of yet another push of cold
Canadian air by the weekend. As far as precipitation, models do
not agree on timing or exact features, they do agree precipitation
will continue through the end of the week albeit with less
accumulation and intensity.
AVIATION...Snow will be present at times across the Northern
Rockies air space during the next 24 hours. Strong westerly flow
aloft will prevent much of the snow from reaching valley floors
for very long, however instances of reduced ceiling and visibility
will be found at KGPI, KMSO, and KSMN throughout today. Another
rush of cold air from east of the Continental Divide will arrive
at KGPI near 23/1700Z, with northeast winds gusting to 25 knots
combined with intermittent snow thereafter through sunset. Terrain
obscurations will be common, particularly near KMSO southward,
where the bulk of snow activity will be occurring during the next
