What forecasters said that day
The local office's own words before this high wind 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 high wind warning went out at Dec 13, 11:46 PM CST, 4 hours 23 minutes earlier.
Area forecast discussion, Dec 13, 11:46 PM CST, 4 hours 23 minutes before
Area Forecast Discussion National Weather Service Des Moines IA 1146 PM CST Mon Dec 13 2021 ...Updated for the 06z Aviation Discussion... .DISCUSSION.../Tonight through Monday/ Issued at 254 PM CST Mon Dec 13 2021 Key Messages: - Extreme winds Wednesday afternoon and evening. High Wind Watch expanded. - Record setting warmth Wednesday - Conditional severe storm risk Wednesday afternoon and evening Surface high pressure to the north has allowed for southerly winds to make a slow return across the area today. GOES-East Day Cloud Phase imagery has shown the snowpack still in place across northern Iowa slowly being eaten away through the day as warm air make sits way north. By Tuesday warm air advection increases across the area as high warm into the upper 50s south and low 40s north (where snowpack will continue to shrink). Wednesday is without a doubt the most significant weather day in the current forecast period with several facets to the system. Most Iowans will catch on to the warmth on Wednesday. Yes, it is going to be quite warm. Record breaking warmth, even. With highs in the 60s to low 70 forecast, daily temperature records will be easily broken at a number of locations and all-time December temperatures records are certainly within reach (details on that below in the Climate section). This warmth is remarkable in and of itself, but it is NOT the main story. Of primary concern on Wednesday and Wednesday night will be the extreme winds forecast across the area as a robust low pressure system rapidly deepens out of Colorado and across the central plains before lifting into the midwest. The pressure gradient across Iowa is very sharp with surface pressure rises of ~20mb/6hrs in the GFS on the back side of the low. GFS soundings across the state also consistently show 75 to 85+ kt gusts at the top of the mixed layer, around 825 mb. While these winds may not be fully realized, they are an indication of the strength of this system. Within ensemble guidance, the EC has 8 members with 6 hour maximum gusts of 70+ mph at DSM and the GFS has nearly 3/4 of its members with gusts over 60 mph. The High Wind Watch remains in place across the area and was expanded to include more of SE IA. Further expansion is certainly possible. The third element of the system is the conditional severe weather threat. This will key on whether there is enough thermodynamic contribution. Recent GFS runs indicate 500-1000 J/kg of MLCAPE including 100-300 J/kg of 0-3km CAPE. Shear in the area is obviously extremely high at 50-70 knots, supportive of discrete storm mode. Low topped supercells are a risk with the discrete mode due to high shear, however there remain the question of whether the shear tear up the updraft before storms can get going and prevent storm form fully realizing the thermodynamics. If storms do form, storm motion will be extreme. SPC did issue a rare midday update the the Day 3 outlook, typically only updated once a day shortly after midnight. With this update a Marginal risk of severe storms was expanded across much of the CWA, highlighting the concern for damaging wind gusts. Given the low CAPE, high shear environment, the tornado potential is also concerning. CIPS analog severe guidance suggests wind threat with convection across area based on past events and also highlights similarity to 11/12/2005 event which produced several tornadoes in Iowa. This system quickly exits overnight with quiet conditions forecast through the rest of the period. Temperatures will drop back closer to seasonal averages through the end of the week and weekend with little in the way of precipitation forecast. && .AVIATION.../For the 06Z TAFS through 06Z Tuesday night/ Issued at 1129 PM CST Mon Dec 13 2021 VFR conditions are expected until about 00Z Wednesday. Winds will shift to be out of the south and increase by midday Tuesday with low clouds moving into the area Tuesday evening dropping CIGs into MVFR with some IFR CIGs possible as well after 00Z. && .CLIMATE...
