The episode as NWS TFX wrote it up.
An upper level disturbance embedded in northwest flow brings a bit of increased winds and areas of light snow to the region. Gusty winds from about Cut Bank to Great Falls are found. These winds are near high wind criteria in the sustained thresholds. Holding off on high wind products as winds should go on a diminishing trend after passage of the |mentioned disturbance.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Great Falls, MT wrote its last area forecast discussion before the first event at Feb 4, 4:59 PM MST, 2 hours 46 minutes earlier.
Area Forecast Discussion National Weather Service Great Falls MT 459 PM MST Tue Feb 4 2020 ...AVIATION SECTION UPDATED... .SYNOPSIS... Clouds increase overnight as the next storm system approaches the region. Snow will develop over the southern and western Montana Wednesday night. Expect the snow to continue over these regions Thursday into Friday morning. A second storm system will affect the region this weekend, with another round of snow and colder temperatures. && .DISCUSSION... Skies remain clear over most of the state today. Satellite imagery shows a long stream of dense clouds moving into Northwest Montana, associated with an upper level jet that extends well back into the central Pacific. A moist northwesterly flow develops on Wednesday, as a fairly strong upper level disturbance moves southward into the region. Widespread snow, heavy at times, is likely over portions of the Rocky Mountain Front, Central MT and Southwest MT from Wednesday afternoon through early Friday morning. The heaviest snow amounts will occur over the southwest Mountains, causing difficult travel into winter recreation areas and increasing avalanche potential. There remains some uncertainty in storm total snow accumulations in the Southwest valleys, particularly with regard to snow levels and valley temperatures. Winter storm watches remain in effect. Saturday through Tuesday...A 2nd storm system is progged to move through the region on Saturday and exit the area on Sunday. Snow amounts of several inches look possible with this system. Additionally, some convective snowfall is possible with the 2nd system, resulting in some high snowfall rates. Winter weather highlights will likely be needed for portions of the region for this event as well. Monday looks to be mostly dry, with increasing chances for snow again by next Tuesday. Overall NBM guidance looked a bit on the warm side, so afternoon temperatures were adjusted down a few degrees from Sunday through Tuesday. && .AVIATION... Updated 458 PM MST Tue Feb 4 2020 (05/00Z TAF Period) VFR conditions are generally expected over the next 24 hours across the forecast area but a passing disturbance will bring increasing mid level clouds this evening and mainly mountain precipitation later tonight into Wednesday along with some periods of MVFR conditions over southwest Montana. Note that KWYS will likely IFR or even LIFR at times. Gusty southwest winds will continue over the plains of north central Montana, especially along the Northern Rocky Mountain Front and adjacent plains (including KCTB), where gusts could exceed 35 kt at times. && .PRELIMINARY POINT TEMPS/POPS...
