469 WWUS43 KDMX 110928 WSWDMX URGENT - WINTER WEATHER MESSAGE National Weather Service Des Moines IA 328 AM CST Thu Jan 11 2024 ...Accumulating Snowfall with Gusty Winds Tonight Through Friday... .A multi-faceted winter storm will pass through the state starting tonight and lasting through Friday. Snowfall amounts from 5 to 10 inches are expected over much of central Iowa along with winds gusting over 40 mph Friday afternoon into early Saturday. The combination of gusty winds, snow on the ground from the previous winter storm, and new, fluffy snow falling tonight into Friday will lead to a significant blowing snow threat on Friday into Saturday. The blowing and drifting snow may lead to near-whiteout conditions, especially in open and rural areas with the hazardous conditions continuing well beyond the end of the falling snow. Therefore, hazardous travel conditions are expected through much of the state on Friday, including both the morning and evening commutes, with impacts extending into at least early Saturday. Temperatures will also fall to the single digits above or below zero by early Saturday with wind chills near to well below zero by Friday night, adding an extra layer of risk to travel on Friday.

What forecasters said that day
The local office's own words before this winter storm 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 winter storm warning went out at Jan 10, 11:45 PM CST, 3 hours 43 minutes earlier.
Area forecast discussion, Jan 10, 11:45 PM CST, 3 hours 43 minutes before
Area Forecast Discussion National Weather Service Des Moines IA 1145 PM CST Wed Jan 10 2024 ...Updated for the 06z Aviation Discussion... .DISCUSSION.../Tonight through Wednesday/ Issued at 252 PM CST Wed Jan 10 2024 Key Messages: - Quick hitting system late this afternoon and evening may produce a quick inch or more of snow central and east. - High impact winter storm likely to impact Iowa Thursday night through Friday night with potential for significant snow and blowing snow. - Arctic cold arrives Friday night and through much of next week. Wind chill headlines will likely be needed at times. The weather systems continue to line up for the region. A compact yet potent short wave as been swirling east across Nebraska today and is currently over far eastern Nebraska. This system has been battling the lack of moisture and therefore has not produced much snow and reduced visibilities yet. However, continue to monitor some moisture lifting back north from the Gulf that should link up with this system and lead to an increase in areal snow coverage. In addition, ample forcing is available for a brief period with one inch per hour rates especially east of Interstate 35 and south of Highway 3. Total amounts should generally be 2 inches or less, again highest amounts east. While the amounts are generally light, travel impacts are possible considering some roadways remain partial snow and ice covered already and the snow rates could quickly cover roads further once again. An SPS is out through this evening for parts of central and east central Iowa. The big system in the forecast is still on track to impact the region by late Thursday afternoon and through Friday night. This system is trending further to the northwest that the forecast from 24 hrs ago as the upper level system closes off earlier and leads to this system. Highlights (or low lights, pending your perspective) of this system include as strong low level moisture transport northward from the Gulf. This system will have a strong push of theta-e advection followed by the development of a TROWAL feature as warm air and moisture wrap around the system. The TROWAL may result in an enhanced region of banded heavy snowfall. Convective properties are possible with this system and there is a better signal for slantwise convective potential into central Iowa along with general elevated convection possibly reaching the far southeast. Finally, snow crystal morphology is trending dendritic with along with the dendritic growth zone region deepening as colder air arrives therefore, snow to liquid rations will be near to above climatology. All in all, pending the exact track of this storm, another system with warning criteria potential snowfall, with an a greater than 50% chance of heavy banded snow along the TROWAL should it set up over Iowa as progged. The Arctic cold will begin to filter into Iowa during this evening with increasing cold advection. This coupled with a strong pressure gradient and mixed layer winds will lead to the potential for wind gusts of 40 to 50 mph mainly later Friday and Friday night. Given the current snow cover in place and storage areas already partially full, blowing snow will be a greater impact than this past event. Worst case scenario, this could turn into a Blizzard. For now will highlight significant snow and blowing snow possible. Will be issuing a Winter Storm Watch for Thursday night through Friday evening for the entire area. Will continue to provide higher resolution of timing and location as confidence increases. Finally the Arctic air will follow in what will be a prolonged cold spell that may feature several days with temperatures below zero for highs (Sunday and Monday) and periods with wind chill advisories and warnings. A Wind Chill advisory may be needed as soon as Friday night over the west and a warning may be needed area wide for Saturday night into Monday. This Arctic cold will be coming in waves with potential for slightly improved conditions Tuesday then another wave arriving around Wednesday. There will be a few periods with light snow as well. && .AVIATION.../For the 06Z TAFS through 06Z Thursday night/ Issued at 1142 PM CST Wed Jan 10 2024 Period of IFR cigs expected until improving to MVFR after 12z.
