What forecasters said that day
The local office's own words before this wind chill advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Green Bay, WI wrote its last area forecast discussion before this wind chill advisory went out at Dec 24, 5:42 AM CST, 6 hours 17 minutes earlier.
Area forecast discussion, Dec 24, 5:42 AM CST, 6 hours 17 minutes before
Area Forecast Discussion...UPDATED National Weather Service Green Bay WI 542 AM CST Sat Dec 24 2022 Updated to add short term portion for morning forecast issuance .SYNOPSIS... Issued at 536 AM CST Sat Dec 24 2022 Heavy snow showers in the Lake Superior Snowbelt today. Elsewhere, still windy and cold with blowing and drifting snow, especially in open areas. A chance for snow Christmas night, then warmer next week. The mid-latitude upper flow across NOAM consisted of a rather broad ridge out west and an eastern trough comprised of the deep vortex that wrapped up out of the intense cyclone that brought the winter storm conditions to the area the past couple days. The trough will linger for a few days before weakening. That will allow the westerlies across the CONUS to trend toward a southern- stream dominated split flow regime during the final days of 2022. Cold conditions will persist through Monday, then temperatures will quickly warm to above normal. Once in place, the milder weather will probably be around for a little while. Precipitation for the period will depend primarily on what occurs with a southern stream cyclone late in the period. Given that the limited opportunity for substantial precipitation and the uncertainty in the track of the system so far out, the best estimate is for AOB normal amounts. && .SHORT TERM...Today...Tonight...and Sunday Issued at 536 AM CST Sat Dec 24 2022 Land-based headlines were left unchanged with the morning forecast issuance. Winds were not quite as strong as anticipated yesterday. That was probably due to slightly weaker winds above the surface than originally forecast, and colder surface temperatures which resulted in a bit more stability from the boundary layer up into the low-levels of the free atmosphere. But a strong surface pressure gradient will remain across the area today, and 850 mb winds of 45-55 kts will be overhead all day. Although some of the loose snow has probably settled into drifts, feel the winds will still be sufficient to generate enough blowing and drifting snow for open areas to experience a significant reduction in visibility, and to warrant keeping the WW.Y in effect today. In addition, roads have a tendency to ice over after being plowed when drifting snow brings a thin layer of fresh snow over the pavement which gets packed down by passing vehicles. Wind chills were currently meeting advisory criteria (<= -20) over about the WSW 1/3 of the forecast area. That should continue into early afternoon and will wrap that hazard into the ongoing WW.Y. After a short respite, wind chills will head back down this evening. The latest forecast calls for wind chills of -20 to -25 over central WI from mid-evening through mid-morning Sunday. A large area farther N and E has the WCI bottom out around -20, with less harsh conditions in the far NE and lakeshore areas. So we will likely need a WC.Y for at least central WI. But there is a lot of uncertainty over exactly how much of the rest of the area it will need to cover. Given that, and the ongoing headline for the blowing and drifting snow, opted to forego issuing the WC.Y with the morning issuance. This will also help keep the focus on the hazardous travel conditions in open areas today, and allow the next shift the benefit of basing the headline on updated temperature and wind forecasts. The other short-term issue is actually much more significant. Very impressive lake-effect snows continue in Vilas county. KD25 has been AOB 1/2SM most of the night, though some of that was likely due to blowing snow. Still, obs from the 4 METAR sites in Vilas county suggest travel must be very difficult in that area. Air parcel trajectories and thermodynamics will remain favorable for LES through tonight and possibly into Sunday. But the inversion height will gradually lower, and that should be what finally results in a decrease in the SHSN. Running the WS.W through 00Z looked good. Might need something after that, but perhaps a WW.Y might be sufficient. Again, the next shift will be a much better position to make that decision. .LONG TERM...Sunday Night Through Friday Issued at 322 AM CST Sat Dec 24 2022 The main story for the long term portion of the forecast will be the transitions from bitter cold Monday and Tuesday with temperatures climbing well above normal levels for the latter half of next week. Some locations could actually warm into the 40s! The clipper system that was advertised to pass well south of the area Sunday night has shifted to the north on the model runs tonight. Have trended toward the ECMWF/Canadian model solution as the GFS trended even further north. Snow chances were increased moderately for now since the models could shift the system south on upcoming model runs. Currently have less than inch of accumulation based on the ECMWF/Canadian model solution across central and east-central Wisconsin. The cold will continue Monday and Tuesday. A warm front will lift northward across the area Tuesday night into Wednesday. Precipitation is expected to break out north of the front. Models have depicted much of the precipitation north of the forecast area, with only slight chances of precipitation across our northern counties. Will need to monitor to see if the models trend southward on the precipitation. The mild weather is expected to continue Wednesday into the next weekend. There are many concerns in the Thursday and Friday period including precipitation types, the potential for fog, and how mild it can be. For precipitation types, the GFS bufkit is indicating a warm layer aloft which could cause the precipitation to be in the form of rain, drizzle, freezing rain or freezing drizzle or possibly some sleet at times. The cold ground may be a factor for icing until the ground temperatures warm above freezing. Also, numerical guidance on both the GFS and ECMWF indicating dewpoints rising into the 30s Thursday into the weekend. The combination of the snow pack, cold ground temperatures, and rising dew points would suggest fog will be possible at times during this period. It will probably be dense at times that could impact travel before New Years Day. Lastly, with a strong inversion present and the potential for fog and low clouds around, high temperatures on some days may not be reached. Plenty of time to resolve those issues in the coming days. && .AVIATION...for 12Z TAF Issuance Issued at 536 AM CST Sat Dec 24 2022 Aviation weather conditions will be better than yesterday, but drifting snow will probably still be an issue for airport ground crews. MVFR ceilings are likely at times as well. && .GRB WATCHES/WARNINGS/ADVISORIES... Winter Storm Warning until 6 PM CST this evening for WIZ005.

Heavy lake-effect snow showers will continue to move into the Lake Superior snowbelt this morning. The snow, combined with blowing and drifting snow generated by northwest winds gusting to 35 mph will result in near blizzard conditions at times, and very difficult travel conditions. The snow showers will begin to diminish this afternoon. Lighter snow showers will continue into tonight. Travel in the snowbelt will be very difficult at times today, especially in open areas. If possible, consider postponing travel until conditions improve. Farther south and east, from Rhineland through Crandon to near Iron Mountain, the snow showers will not be as persistent. But winds will still be strong, so blowing and drifting snow will affect these areas as well. Use caution while traveling in these areas, especially in open terrain.

Northwest winds gusting to 35 to 40 mph will continue to generate blowing and drifting snow in open areas today. The impact on travel in urban and heavily forested areas will be minimal. But travel through open areas could be much more difficult as the visibility will be significantly reduced at times. Anyone traveling today should be especially alert for the possibility of encountering patches of icy and very slippery pavement in areas where the wind blows a thin layer of snow back across the road after snow plows have cleared off the deep snow. Often in these situations, the thin layer of fresh snow will be packed down by passing vehicles and polished off into a layer of glare ice. The core of the coldest air has shifted east of the area. So although it will still be cold today, temperatures will be 10 to 15 degrees warmer that at the same time yesterday. Wind chill indices of 15 below to 25 below zero are expected in central Wisconsin this morning. Wind chills of 10 below to 20 below zero are anticipated across most of the rest of the area, though slightly less harsh conditions are expected in far northeast Wisconsin. Skowronski
