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 Riverton, WY wrote its last area forecast discussion before this wind chill warning went out at Dec 20, 10:38 AM MST, 2 hours 29 minutes earlier.
Area forecast discussion, Dec 20, 10:38 AM MST, 2 hours 29 minutes before
Area Forecast Discussion National Weather Service Riverton WY 1038 AM MST Tue Dec 20 2022 .SHORT TERM...(Today through Wednesday) Issued at 330 AM MST Tue Dec 20 2022 A lot of talk about today. Like yesterday, with the contrast in conditions, we will split the discussion into West and East of the Divide. West of the Divide...Some light snow is ongoing across the western mountains, but so far things have not been that bad. This should be the story through most of the day today, with mainly light snow through the day and even the early evening. However, things will change later tonight and especially Wednesday morning as the combination of a shortwave trough, an advancing cold front to provide low level lift and the main player, and approaching 170 knot jet, to provide the upper level dynamics. With much of the area expected to be in the left front quadrant of the jet, this is when a bulk of the snow will fall. Snowfall rates of over an inch an hour are certainly possible, and combined with some gusty to strong winds, the period from midnight Tuesday night through around mid afternoon on Wednesday will not be pleasant to be traveling. We will maintain the winter weather highlights as is, although the bulk of the weather will be occur tonight and Wednesday. Concern then shifts to the bitterly cold temperatures. Bitterly cold air will move in behind the front for Wednesday night into Thursday. The good news, although this a relative term, is that the core of the coldest air looks to remain East of the Divide. As for wind chill highlights, it is borderline, so for now we punted to the day shift, as it would not be until Wednesday night at the earliest. All areas will see very cold temperatures though, especially if there is any clearing after the snow ends. Thursday also looks like a bitterly cold day with most areas remaining below zero through the day. The good news is that some slight moderation may move in for Thursday night as some clouds moving in from the west may blanket the atmosphere just enough to keep things milder. East of the Divide and Sweetwater County...Today looks to be the calm before the storm. All in all it looks like more of the same with a gusty wind around Casper and chilly temperatures elsewhere. The inversions have thinned somewhat, so temperatures should be a bit milder. The basins are tricky though. For example, in Riverton, on the west side of town, one spot made it to 23 yesterday, Just 4 miles away as the crow flies, it remained in the single digits. For temperatures today, we have gone with the same logic as yesterday, keep temperatures chilly. If it gets warmer, most people won't complain. The main event begins Wednesday as the push of the coldest Arctic air now over British Columbia and Alberta begins to push southward into northern Wyoming. This will likely mean falling daytime temperatures for most of northern Wyoming and morning highs further south. As for snowfall, the airmass is Arctic so it has very limited moisture capacity. So, amounts should remain light. The exception would be if any snowbands form. These are nearly impossible to pinpoint this far out though. It will be a dry, powdery snow that will blow around easily. And there will be a gusty wind accompanying it. We thought about a winter weather advisory, but since we feel the bitter cold temperatures will be the main story, we decided not to, and will mention the snow in the wind chill highlights. And speaking of the wind, many models show 700 millibar winds increasing to 50 knots or over across Sweetwater County. With the aforementioned powerful jet moving in the enhance downward momentum and the tight pressure gradient developing, high winds are a possibility. We will hoist a high wind watch across Sweetwater County and southern Lincoln county for this. Travel is NOT advised Wednesday afternoon in this area as we will likely have blowing snow and possible high wind. Interstate 80 could be a mess at this time. The snow should end for all areas by midnight Wednesday. This leads to the main story...the brutally cold air moving in for around a 48 hour period. Wednesday looks really cold across much of the area. And, with some breezy conditions lingering, dangerously low wind chills look to be a decent possibility. We have issued a wind chill watch across the central and south zones starting Wed evening until Friday morning. There are a couple of somewhat better developments though. The 700 millibar temperatures are not quite as cold as yesterday for Wednesday through Thursday night, bottoming out around minus 32 rather than the minus 37 from yesterday. But saying that, it will still be very cold. There is some uncertainty on exactly how cold it will get though. The question for Wednesday night is cloud cover. The southern half of the state may stay with clouds, holding temperatures up somewhat. The best chance for clearing will be across the north and that is where the coldest temps will be found. All areas will stay below zero and well below zero for highs on Thursday. As for Thursday night, the coldest will be lifting out in some places. The central basins will still be very cold. In addition, with flow turning southwest somewhat, areas like Casper may see slowly rising temperatures at night as the wind increases. So, there is uncertainty as to how long any wind chill warnings need to go. Nevertheless, the next couple of days still look to be some of the coldest we have seen in a while. .LONG TERM...(Friday through Monday) Issued at 335 AM MST Tue Dec 20 2022 Some moisture moves back into the west Friday and Friday night for areas of light snow in the western mountains and far west valleys. Dry weather is expected elsewhere Friday and Friday night. High temperatures moderate some from Thursday's bitter cold highs. Single digits and teens look good with some of the colder central basins staying below zero. Lows Friday night will be in the single digits and lower teens where the wind occurs. Central basins will range from 10 to 15 below zero. Cloud cover in the western valleys will help keep lows from dropping too far below zero. Saturday and Sunday will see two weather systems pass through the area in a northwest flow aloft. Most of the snow will occur in northwest WY and over the Bighorn mountains. The Sunday system looks a little stronger, so some light snow may occur in the lower elevations of the north Sunday. Temperatures aloft warm quite a bit Saturday and Sunday over the region, resulting in milder highs in the mountains and most of the mixed locations where the wind occurs. Not sure how much the western valleys and central basins will warm up Saturday and Sunday. Kept some highs in the teens in the central basins Saturday with lower 20s in the far west valleys. For Sunday, have kept the central basins in the 20s as well as the far west valleys. Monday looks mostly dry over the area with even milder high temps. It will be windy in the wind corridor Monday. && .AVIATION...(For the 18Z TAFS through 18Z Wednesday) Issued at 1030 AM MST Tue Dec 20 2022 Light snow showers continue over western WY this afternoon. Mountains will remain obscured through the next 24 hours. KJAC will waffle between VFR and MVFR/IFR with passing snow showers until snow increase after 21/06Z, then go down to IFR during heavier snow early Wed morning. Otherwise, VFR conditions at other TAF sites through ~21/09Z. VCSH & MVFR to move into KBPI/KPNA at that time, then likely down to IFR with gusty winds after 21/12Z. Today will continue with breezy and gusty wind at most locations. Arctic front pushes into northern WY just before 21/12Z and moves quickly south. KCOD and KWRL will drop to IFR by 21/13-15Z, and KCPR/KRIW around 21/17Z. North winds with and behind the front should gust 25-30 kts. South of the front will see gusty winds 25-40 kts from the west, likely impacting KLND and KRKS. Snow bands expected to impact central and southern WY from 21/16z-22/00Z to create intermittent VIFR conditions, but very difficult to pinpoint at this time. Arctic air pushes into southern WY after 22/00Z for some low clouds/fog/snow across central and southern WY. Snow will mostly move out of the forecast area by 22/06Z with some patchy low clouds/fog likely into Thursday morning. Please see the Aviation Weather Center and/or CWSU ZDV and ZLC for the latest information on icing and turbulence forecasts. && .FIRE WEATHER... Issued AT 330 AM MST Tue Dec 20 2022 Mainly light snow will continue across the west today, but any heavy snow should hold off until after midnight tonight and into Wednesday. Dry conditions will continue East of the Divide today. Southwest wind will continue from east of Rock Springs through Casper, but wind should remain light to moderate elsewhere. Relative humidity will remain above critical levels. Mixing and smoke dispersal will be generally poor but locally fair to good in the western mountains. An Arctic Front will drop southward on Wednesday and usher in bitterly cold air for Wednesday and Thursday. && .RIW WATCHES/WARNINGS/ADVISORIES...
