What forecasters said that day
The local office's own words before this wind chill warning went out, 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 this wind chill warning went out at Feb 20, 10:17 PM MST, 4 hours 23 minutes earlier.
Area forecast discussion, Feb 20, 10:17 PM MST, 4 hours 23 minutes before
Area Forecast Discussion National Weather Service Great Falls MT 1017 PM MST Sun Feb 20 2022 ...Aviation Section Updated... .UPDATE... Surface pressure continues to rise as the Arctic airmass deepens over the region. Satellite and radar show continuing areas of light to moderate snow from Western Montana, through Central and Southwest Montana, and into Southeast Montana where heavy snow is ongoing. Snowfall has been lighter than forecast in some areas, but continues heavy at times along the slow moving frontal boundary in the southwest. Model analyses indicate a weak upper level shortwave trough over western Montana, poised to cross our region overnight. The forecast was updated to better match observed trends. Forecast snowfall was lowered a bit across North-central Montana where remaining moisture is limited. The existing winter weather advisories and warnings will continue for now given the remaining potential for light snow with the passing shortwave. && .SYNOPSIS... An arctic cold front has passed through much of the region as of this afternoon, with cold temperatures and widespread accumulating snow in its wake. While accumulating snow will gradually taper off Monday into Tuesday, temperatures will continue to steadily fall all the way into Wednesday morning before slowly recovering through the remainder of the week. && .AVIATION... 1017 PM MST Sun Feb 20 2022 (21/06Z TAF period) Low VFR or MVFR to temporary LIFR conditions prevail in light snow. Arctic air moving into the region will deepen the cold air mass and maintain widespread low clouds and snow. A shortwave disturbance aloft is expect to provide an increase in coverage of snowfall overnight across central, and especially southwest Montana. Snowfall rates gradually taper from north to south through Monday afternoon. Refer to weather.gov/zlc for more detailed regional aviation weather and hazard information. && .PREV DISCUSSION... /ISSUED 510 PM MST Sun Feb 20 2022/ Rest of today through Tuesday night...primary forecast concerns throughout the period are the on-going accumulating snow and temperatures, especially low temperatures Monday night and Tuesday night. Arctic front has made it all the the way west of the Continental Divide from Marias through Elk Park Passes, south to the Interstate 90 corridor in Southwest Montana, and east through all of North Central Montana as of early this afternoon, with temperatures ranging from the single digits and teens above zero across Central and North Central Montana, to the 20s and 30s in Southwest Montana. Light to at times heavy snow was falling across most of the CWA, with the heaviest snow falling within convective bands located across eastern portions of Southwest Montana and along and west of the Interstate 15 corridor in Central and North Central Montana. Winter Weather Advisories/Warnings remain in effect and unchanged for the entire CWA, with current thinking being that as these highlights are cancelled/expired through the day on Monday that there will be the need to issue Wind Chill Advisories/Warnings (as wind chills are currently being supported by either of the two current highlights). Expect the most persistent and heaviest area of snowfall through the remainder of the day and night to be focused across eastern portions of Southwest Montana, mainly along and southeast of Whitehall, to Toston, to Ringling line, which would place much of the I-90 corridor, especially Bozeman and Bozeman Pass beneath the heaviest snow. Areas south and east of the aforementioned line can expect an additional 6 to 12 inches of snow. Given weak instability and strong dynamics across Southwest Montana this afternoon and evening, would not be surprised if a few instances of thundersnow is reported. Snow will gradually decrease in intensity from north to south through tonight and Monday morning across the entire CWA; however, periods of light snow will likely persist through Tuesday in northerly and easterly upslope favored areas. - Moldan The other concern is with temperatures and resultant wind chills. Statistical guidance, especially the GFS Ensembles, are reluctant to bring as low temperatures to parts of the region as the European ensembles and other model ensemble suites, possibly due to hanging on to prolonged cloud cover well into Wednesday morning. The operational NBM 4.0 and experimental NBM 4.1 version both take a middle ground with its deterministic forecast midway between the GEFS and the EC ensembles, but with the GEFS being such a warm outlier, if this model ensemble guidance proves to be incorrect then temperature forecasts for Tuesday into Wednesday may need to be adjusted downwards as much as 5 to 10 degrees for some areas, with lows possibly closer to the -20s than the -10s. - CC Wednesday through next Sunday...Temperatures slowly moderate Wednesday through the remainder of the week under active northerly flow aloft and weak surface winds. This will mean dry weather but with weak pressure gradients and a lack of significant temperature advection, with low-level inversions likely keeping cold air trapped in the valleys and typically sheltered areas through the end of the week. By the weekend, especially toward next Sunday, flow becomes more westerly, with an upper ridge moving in from the west. This will likely allow for increasing winds in the lee of the Northern Rockies and a resulting warming trend for parts of the region, especially the eastern slopes. - CC && .PRELIMINARY POINT TEMPS/POPS...
