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 Des Moines, IA wrote its last area forecast discussion before this wind chill warning went out at Dec 22, 11:44 PM CST, 3 hours 19 minutes earlier.
Area forecast discussion, Dec 22, 11:44 PM CST, 3 hours 19 minutes before
Area Forecast Discussion National Weather Service Des Moines IA 1144 PM CST Thu Dec 22 2022 ...Updated for the 06z Aviation Discussion... .DISCUSSION.../Tonight through Thursday/ Issued at 305 PM CST Thu Dec 22 2022 Key Messages: - Blizzard conditions combined with dangerous wind chills will create life threatening conditions for anyone that ventures out tonight through Friday, particularly over northern/central Iowa - Bitter cold through Saturday morning, then gradual upward temperature trend - Light snow chances parts of Iowa Christmas Day Details: The snow has pushed into eastern Iowa as of early this afternoon with COOP and spotter reports showing snowfall was between 2 to 4 inches in most places. Several reports between 4 and 5 inches came were received from around the Webster, Hamilton, and Boone county area. The arctic front that brought this snowfall is over eastern Lake Michigan and stretches to near Little Rock to near San Antonio. The parent trough of this front is digging southeastward toward the western Great Lakes while surface low pressure develops over the Ohio Valley. As this surface front pulls away, the clouds are also departing to the east leaving behind a clear sky over western into central Iowa. Winds in the wake of the front have been increasing with gusts between 25 and 35 mph this morning and that has increased into the 30 to 40 mph range now. Temperatures continue to fall and with the increasing winds, the entire area is solidly in Wind Chill Warning criteria with most places at or below -35F. With the fresh snow and these winds, GOES-East day snow fog RGB show a widespread field of blowing snow, which has a bit of milky appearance to it over western/central Iowa, eastern/central South Dakota, eastern/central Nebraska, and Minnesota. Frankly, it is amazing to see such a large area of blowing snow. Visibilities thus far this afternoon in Iowa have generally bottomed out around a half a mile with KEST (ASOS), KEBS (AWOS), and KCIN (AWOS) reporting such. Recently, KCAV (AWOS) reached a quarter of a mile. We've also seen social media reports around Pocahontas of quarter mile visibility, drifting snow, and county plows being pulled off the roadways. As the surface low moves into the eastern Great Lakes, explosive deepening of this low will occur, which will increase the pressure field between the eastern Great Lakes and a ~1050mb high moving down the eastern spine of the northern Rockies. For Iowa, this means winds will be stronger tonight and Friday then they have been so far. Current forecast for wind gusts is toward the BUFKIT mean mixed layer wind versus the top of the mixed layer, which are impressive around 50 knots over northern Iowa and also shown in HRRR runs. For now, peak gusts were kept between 40 and 50 mph after midnight tonight into Friday evening, but will monitor trends in case we need to trend towards the top of the mixed layer. With these stronger winds continuing to loft snow, we continue to forecast blizzard conditions tonight into Friday and the headlines are in good shape. Those blizzard conditions will be most likely in rural, open areas so if you are in a sheltered, city/urban location and it doesn't look bad, do not be deceived. While the blizzard conditions alone are a concern for personal safety, the bitterly cold air with these winds will create wind chills of -35F or lower across all of Iowa. Stealing from the midshift's discussion, wind chills this low are uncommon and happen on average maybe a few hours per year (10hr/yr at Estherville to 2hr/yr at Des Moines), so this is a somewhat rare, prolonged cold scenario for Iowa. If you were to venture out tonight or Friday and become stranded due to a vehicle break down, stopped in traffic due to an accident, or go off the roadway due to poor visibility, these wind chills would be dangerous and life threatening if exposed for a short period. We don't use those words lightly or often, but that is the current scenario that we see unfolding, particularly over northern and central Iowa. Wind chills will generally be below -25 if not -30F or lower across the state through Saturday morning. While the Wind Chill Warning conditions are currently included in the Blizzard Warning and Winter Storm Warning, will need to issue a separate wind chill headline once the other warnings end. While the forecast is dry through Friday and Friday night, the RAP shows a thin layer of saturation dropping into northern Iowa in the afternoon and evening with little lift noted in cross sections. The RAP and HRRR BUFKIT soundings show that the not fully saturated profile warms (yes, warms) to near the lower end of the -18 to -12F dendritic growth zone while at the same time further drying. There is no ice introduction so we could see freezing drizzle or perhaps flurries briefly over northern Iowa, but confidence was too low to include it at this time. It will remain blustery through Saturday as the trough and surface low wrap up and move northeast into the Quebec province. With around 36 hours of blowing snow, crystals will have been fragmented down and the relatively lighter winds should result in blowing snow being not be as prevalent. There could still be streamers across roadways, which could pose a travel risk. After Saturday morning, the coldest period will be in the past with temperatures forecast to rise gradually into next week. The next chance for light snow will come from a clipper system that looks to track through the region later this weekend. Moisture will be limited and it will take top down saturation to overcome the dry low levels. Cross sections do not show robust lift, but sufficient for light snow. Compared to yesterday, the 100 member grand ensemble is slower with the arrival of snow holding off until later in the afternoon with it more tracking through southern Minnesota, northeast half of Iowa, and southwest half of Wisconsin. So, a bit of light snow with amounts around an inch possible in parts of the state are possible Christmas Day. && .AVIATION.../For the 06Z TAFS through 06Z Friday night/ Issued at 1139 PM CST Thu Dec 22 2022 Main concern remains IFR/LIFR visby reduction for blowing snow for the entire period and beyond. Gusty winds will also prevail through the period, increasing at sunrise and peaking to near 50kts at sunset. Highest winds will be at eastern terminals.
