What forecasters said that day
The local office's own words before this wind chill advisory 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 advisory went out at Jan 14, 3:27 AM CST, 20 minutes earlier.
Area forecast discussion, Jan 14, 3:27 AM CST, 20 minutes before
Area Forecast Discussion National Weather Service Des Moines IA 327 AM CST Sun Jan 14 2018 .SHORT TERM.../Today through Tonight/ Issued at 327 AM CST Sun Jan 14 2018 Confidence: Medium to High Short wave tracking southeast into Iowa/Nebraska now spreading light snow across the southwest and eventually working east today with warming temperatures through the afternoon hours as a weak warm front accompanies the light snowfall. Winds will remain light through the daytime event today so few if any impacts are expected. Snowfall totals across the south likely to be under an inch with this warm air advection/mechanically driven snowfall. Stronger wave showing up in Goes 16 mid-level water vapor imagery spread across Saskatchewan/Western Manitoba. The low is expected to quickly dig nearly due south and deepen a sfc wave into northern/east Central Iowa by 06z tonight. Along with that a closed H850 low will track from near International Falls at 00z Monday southeast to near La Crosse by 12z Monday. A band of snow will accompany the low and passage of a strong Arctic cold front which will enter northwest Iowa by 00z and quickly track southeast through the remainder of the forecast area by 06z. Light snow should enter the northwest between 20-21z and spread quickly southeast through the evening hours. The models differ a bit on placement of the sfc low location by 06z but both the GFS/Euro and Hires models have been consistent in precipitation amounts of about .06 to .09 with this event from north central through the east central counties...slightly lighter amounts back to the west. With snow ratios of 20 to 23:1 this will likely drop between 1 to 2 inches of snow northeast. Once the cold front arrives...winds will be on the increase between 06 and 12z when sustained winds will reach 15 to 25 mph with gusts to 30 to 35 mph at times over the northeast overnight. At this juncture will be holding off on any headlines for the event. The winds will lag the main snowfall by a couple of hours...reducing the risk of visibility impacts. WPC sref ensemble vsby probabilities suggest that there is only a 10-20% chance of any low visibilities during the event. However...after the winds pick up still expect to see some blowing snow so have added patchy blowing snow over the northeast half. Fracturing is likely to occur resulting in some settling...but certainly between 06 and 12z snow will probably blow over roads and early morning commuters Monday may need a heads up on road conditions if this occurs. The other big story will be the cold weather. After coordination between offices and internally between short/long term...have decided to issue a Wind Chill Advisory to US 30 from 09z tonight through 18z Tuesday. More details about the rest of the area/period can be found in the next section of the AFD. Temperatures tonight will quickly fall into the single digits below zero north after midnight and fall to the single digits south and 5 to 10 below by 12z north. Wind chills will be near -20 from US 30 north to the border by 12z and remain near that mark the entire day. .LONG TERM.../Monday through Saturday/ Issued at 327 AM CST Sun Jan 14 2018 Summary...Arctic air intrusion will have been well under way by the start of the forecast period, bringing about temperatures that will not eclipse single digits until Wednesday afternoon. With breezy NW winds, dangerous wind chills, especially Mon night into Tue morning, will tag along as well. Relief comes to end the week as temps rise above freezing. Monday through Wednesday Morning...Cold front should be through the state by 12z Monday, leaving behind strong CAA and 20-25 mph NW winds and gusts approaching 35 mph. Blowing snow concerns, at least the degree of, are a bit questionable considering that only around an inch may have fallen previously, the heavier amounts relegated further NE closer to Wisconsin, and the greatest probability will likely reside prior to 12z. Regardless, have kept blowing snow mentions, perhaps over zealously, in through Monday given the sustained strong winds. Overall, the bigger concern through this window will be the sustained cold and wind chills. Highs Mon/Tue will only be in the single digits above zero, along with lows Tue/Wed morning ranging from around -5 to -15 degrees. While not as outright cold as previous arctic outbreaks this season, winds will be up throughout its time here, dropping wind chills into the -25 to near -40 degree range from Mon morning through Tue morning. Wind chill headlines are a certainty. An advisory currently resides from Highway 30 north from early Mon morning thorugh Tue morning, and will almost certainly see an expansion southward and upgrade to warning over its existing area for Mon evening into Tue. Wednesday Afternoon through Saturday...Relief in the way of warmer temperatures comes to the region as the upper level trough quickly slides eastward and zonal flow to weak ridging prevails. Primarily southerly surface flow will raise temps into the teens Wed and eventually into the mid 30s to low 40s by Fri and Sat. While quiet on the discernible weather front, models show increasingly divergent solutions as early as Thur evening. Biggest potential impact to the forecast lies just outside of this package, Sunday, where GFS paints potentially significant winter weather as an upper level closed low passes while the Euro depicts a quieter and slower open trough passage. && .AVIATION.../For the 06Z TAFS through 06Z Sunday night/ Issued at 1143 PM CST Sat Jan 13 2018 System dropping southeast in broad northwest flow will continue to affect Iowa this forecast period. Low clouds, albeit VFR, will expand across much of the forecast area tonight with generally cloudy conditions on Sunday. Some MVFR ceilings will be likely in the north and west by midday with lowering ceilings to IFR in areas of snow by Sunday evening as an arctic cold front plunges through the state. The snow will also restrict visibilities during the evening and blowing snow is possible by the end of the period, especially in northern Iowa as strong northwest winds develop in the cold advection behind the boundary. && .DMX WATCHES/WARNINGS/ADVISORIES...
