What forecasters said that day
The local office's own words before this winter weather advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS La Crosse, WI wrote its last area forecast discussion before this winter weather advisory went out at Jan 22, 11:39 AM CST, 2 hours 36 minutes earlier.
Area forecast discussion, Jan 22, 11:39 AM CST, 2 hours 36 minutes before
Area Forecast Discussion National Weather Service La Crosse WI 1139 AM CST Fri Jan 22 2021 .SHORT TERM...(Today and tonight) Issued at 251 AM CST Fri Jan 22 2021 Pretty quiet across the region early this morning, with clear skies for most of the area as high pressure continues to build in from the west. Somewhat breezy northwest winds continue to usher in cooler air, as temperatures around 3 AM were in the single digits in many locations. This will set the stage for a much colder day compared to the past few days. Despite plenty of sunshine, highs will generally top out in the teens...roughly 10 degrees below normal for this time of year. Winds will gradually subside through the afternoon, but we'll still have plenty of wind chill values in the single digits above and below 0. With surface ridging in place overnight, expect continued quiet, clear, and cold weather as we see widespread lows below 0. The favored cold spots in central Wisconsin should tank pretty quickly and bottom out in the negative teens. However, with the surface ridge axis progged to move off to the east by the early morning hours, may not get quite as cold as we would on other ridging nights, as light southerly winds could buy us a few degrees. .LONG TERM...(Saturday through Thursday) Issued at 251 AM CST Fri Jan 22 2021 Well-advertised round of accumulating snow is still on track to spread eastward across the area beginning Saturday afternoon, tapering off Sunday morning. Looks like a largely thermodynamically- driven event, not much dynamic forcing. Mid-level flow is nearly zonal, with only a subtle southern-stream shortwave trough crossing the Central Plains and a much stronger northern-stream shortwave grazing northern MN. Decent return flow will be in place over the Mississippi Valley, especially Saturday night as the nose of a low level jet drifts east across the forecast area. This will bring ample moisture into the area with PWATs climbing to just shy of 0.5" in our south. Meanwhile broad warm air advection/isentropic ascent spreads across the area Saturday afternoon-night. Models are in rather good agreement on many important details of this system, including onset/ending timing, ptype = all snow, deep dendritic growth zone, and bulk of accumulating snow occurring Saturday night. QPF and snow ratios remain the forecast sticking points. GEFS plumes continue to run on the higher end of guidance with clustering around 0.3 to 0.4" and some higher and lower outsiders. Meanwhile WPC super ensemble plumes show ECMWF members clustered around 0.2 to 0.25", with no members reaching 0.3". Available hi-res guidance is coming in more in line with higher GEFS totals, but this seems high for a system with such little dynamic forcing and only transient frontogenesis banding. So for now prefer WPC's more conservative blend. As for snow ratios, forecast soundings' 1-2 km deep DGZ suggest the need for ratios on the order of around 16-18:1. However, even these higher values are below the 50th percentile among guidance, so it's possible ratios may need to be further increased, which would increase forecast snow totals a bit. With more conservative QPF, snow totals have come down a bit since yesterday. Current forecast calls for a broad 3 to 5" across most of the area, 1 to 3" in the far south by daybreak Sunday. A future advisory is likely, but unless there is growing consensus for higher banded QPF, do not anticipate any watches/warnings at this time. More of a lighter/fluffier variety of snow to make for easier clean up. Snow should clear out of our eastern counties by late morning, and then will be monitoring another system moving into the Ohio Valley Sunday night into Monday. Most guidance has impacts from this system staying to our south, but confidence remains low as several EPS members do bring some snow into our area. Using a model blend, current forecast has small precip chances across our south. Perhaps some additional light snow mainly west of the Mississippi River towards midweek with a weak wave. Temperatures look to remain fairly typical of late January through the period. && .AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon) Issued at 1139 AM CST Fri Jan 22 2021 VFR conditions are expected through the TAF period, with snow and MVFR to IFR conditions just beyond the end of the TAF period Saturday afternoon. High pressure will keep light northwesterly to westerly winds into this evening, with mostly clear skies. There is an area of MVFR clouds out in the Dakotas/western MN that is very slowly moving east, so will have to watch that these don't hold together and reach our area by early morning, though guidance suggests they will not make it. As the high slides east overnight, winds will gradually become more southerly into Saturday morning. VFR high and mid clouds will increase Saturday morning ahead of a system approaching from the west that will bring snow and MVFR/IFR conditions Saturday afternoon. && .ARX WATCHES/WARNINGS/ADVISORIES...
