227 WWUS43 KDMX 072134 WSWDMX URGENT - WINTER WEATHER MESSAGE National Weather Service Des Moines IA 334 PM CST Thu Feb 7 2019 ...Blowing Snow Continues into the Evening with Dangerous Wind Chills Overnight... .No additional snow is anticipated but conditions should change little into the evening with persistent strong winds producing continued blowing and drifting snow and even blizzard conditions at times north. Visibilities will be significantly reduced at times, and even to a quarter mile or less in rural, open areas. Lingering snow and icing may linger over central and parts of southern Iowa as well producing hazardous driving conditions. The winds and blowing snow should diminish somewhat overnight, but still be sufficient to drive wind chills into the 20s and 30s below zero by early Friday morning.

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 Feb 7, 3:17 PM CST, 17 minutes earlier.
Area forecast discussion, Feb 7, 3:17 PM CST, 17 minutes before
Area Forecast Discussion National Weather Service Des Moines IA 317 PM CST Thu Feb 7 2019 .SHORT TERM.../Tonight through Friday/ Issued at 314 PM CST Thu Feb 7 2019 The primary concerns will be ongoing blowing snow followed by bitter cold temperatures and wind chills into Friday. Nearly all of our additional precipitation has ended outside of shallow convective rolls in the strong wind and cold advection, which is evident in visible satellite imagery and radar in long pulse/VCP 31. No additional accumulation is expected with these but forecast soundings show little change in the 1km mixed layer through the evening, possibly even a touch higher, with steady sustained winds and gusts likely to 40 mph+ at times north. Thus the favorable environment for lofting snow and the current blowing snow event should persist essentially unchanged through the evening. Calls to northern Iowa dispatch offices suggest true blizzard conditions are marginal, but recent Estherville and Mason City observations easily have sufficient wind speeds and continue to drift back and forth either side of ¼ mile visibility so will leave the Blizzard Warning intact. Farther south, static cameras and plow cams show significant blowing snow at times in rural areas, and there is even some shallow blowing and drifting in our parking lot, so confidence in poor conditions in open areas is there to extend the current Winter Weather Advisory into the evening and matching the Blizzard Warning midnight expiration. Sensible conditions will seem even worse after nightfall. This will also help simplify headlines somewhat with a clear break point into Wind Chill Headlines at midnight. Winds should diminish somewhat overnight but still be sufficient to drive wind chills well into advisory criteria, and warning criteria north. Have tried to blend expectations and local and adjacent office criteria into a simple block warning headline across northern Iowa and an advisory elsewhere, lasting through the morning. The advisory may linger a bit long south, but felt it could be canceled early there rather than trying to get too tricky with north to south exit timing. Regarding highs tomorrow, undercut guidance a bit as models are currently reflecting a warm bias, and have even over the past several days. While not as extreme as the recent arctic outbreak, lows tonight will still dip to below zero readings area wide, including sub -10F north. Highs tomorrow will not be much better, just reaching zero north and no better than the teens far southwest. .LONG TERM.../Friday night through Thursday/ Issued at 314 PM CST Thu Feb 7 2019 Temperatures will drop into the near zero across southern Iowa friday night, with temperatures in the teens below zero across northern Iowa. High pressure will slide off towards the Great Lakes region overnight, with winds becoming light and switching to the southeast. Although temperatures will be quite cold, with light winds apparent temperatures should remain above advisory criteria across much of the area. Northern counties dip into the -20 to -25 range and may need an advisory through Saturday morning. The upper level ridge axis passes across through Saturday with southeast winds increasing waa, temperatures will be in the mid teen north to upper 20s south. Meanwhile, lee cyclogenesis will help to enhance a short wave as it move across the rockies Saturday night. This system will bring a quick shot of light snow across the area Sunday, through amounts look to remain fairly light - generally 1 to 2 inches. A brief period of light freezing drizzle may be possible across far southern Iowa where soundings indicate dry air aloft resulting in loss of ice introduction. There will be a brief lull before the next system arrives quickly on the heels of Sunday's as a trough digs across the northern plains and into the midwest. It will begin to impact the area by mid day Monday. While there is initial agreement in how the models handle this storm, they diverge quickly. While the Euro quickly lifts the system across the great lakes and into the northeast, with precip ending Tuesday evening, the GFS develops a broad deformation zone with snow lingering through midday Wednesday. While previous model runs have indicated that the system would intensify and develop a closed low, 12z runs of both the GFS and Euro indicate a more open wave pattern and reduces the higher winds and blowing snow potential on the backside of this system. High pressure builds back across the area wednesday into thursday, with indication of a late week system to bring another shot at wintry precipitation. && .AVIATION.../For the 18Z TAFS through 18Z Friday afternoon/ Issued at 1214 PM CST Thu Feb 7 2019 IFR and LIFR conditions remain in place across much of the northern half of the state, mainly due to blowing rather than falling snow. Wind gusts into the 30s /kts/ should continue but blowing snow impacts should diminish with time leading to a gradual return to MVFR or VFR area wide later tonight. && .DMX WATCHES/WARNINGS/ADVISORIES...
