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 Apr 17, 3:38 AM CDT, 16 minutes earlier.
Area forecast discussion, Apr 17, 3:38 AM CDT, 16 minutes before
Area Forecast Discussion...Correction to periods National Weather Service Des Moines IA 338 AM CDT Tue Apr 17 2018 .SHORT TERM.../Today through Wednesday Night/ Issued at 332 AM CDT Tue Apr 17 2018 Confidence: Medium Today will be pleasant compared to later tonight into Wednesday. Clouds will be on the increase today ahead of the storm with cloudy skies tonight. Highs today will recover to the mid to upper 30s north and the upper 40s to lower 50s over the south. Tonight with the low passing southeast of the region temperatures will fall into the upper 20s north and in the mid 30s across the south. The freezing line will be near the US 30 corridor. Storm still on track to reach Iowa later tonight and bring a quick hit of snow/freezing rain/and wind. Models tonight are tracking farther south and colder than earlier runs. The GFS/Euro/NAM all suggest abundant moisture available for snow production across the north. Deep lift in the H700-H600 layer with potential for elevated instability over the east may lead to more widespread heavy snow farther south. H850 inflow into the storm of 40 to 45 kts from 09z through 17z will aid in 1 inch snowfall rates per hour across the north during that time. Though saturation may take until about 07z across the northwest...went ahead and began warnings/adv over the northwest. Once the precip begins it will quickly cause some impacts with some light icing/sleet and a quick changeover to all snow by 09z as rates pick up over the northwest for the remainder of the day. Over the northeast rain/freezing rain will being initially with a changeover taking place nearer 09z to 12z. None the less...morning commutes will be impacted over most of the north. Farther south a mixture of light icing and light snow will be possible. Though road temperatures may limit any road icing along the US Highway corridor north toward US 20...decided to add a row of counties to for chance that some bridges/overpasses may become slick or briefly ice up in the morning hours. If impacts lessen during the day Wednesday...this portion of the advisory may end earlier. This storm has a lot going for it...possible convection along with strong forcing. Some uncertainty still remains regarding the amount of qpf and how far south the storm may still trend which will affect snowfall amounts. Generally looking for a 6 to 8 inch area of snow north in the warning areas with 2 to 5 inches in the advisory areas along with a glazing of ice there. Day shift will need to carefully evaluate trends and again later tonight. Highs tomorrow will warm into the mid to upper 30s south of US 30 - at best with temperatures holding in the lower 30s over the north. With the snowfall rates quite high...this event will support snow below 35 degrees and likely some compaction will take place but with high snow:water ratios up to 15 to 17 due to tremendous forcing... should be able to see more than 6 inches in the warning areas. .LONG TERM.../Thursday through Monday/ Issued at 332 AM CDT Tue Apr 17 2018 Finally some quiet and spring-like weather in store through the weekend and into the early part of next week. The main focus of the extended was on a another upper level low to pass to the south of the state Friday night into Saturday. Models continue to shift this system south from run to run and confidence is increasing with the better chances of remaining dry across much of the forecast area. Hence the good news, no major winter storm for the weekend for central Iowa and much of the forecast area looks to be near or even slightly above normal Saturday and Sunday. Thursday through Saturday...Surface high pressure builds into the region and becomes centered over Iowa b/t 03-09z Friday. There is plenty of dry and cool air with this airmass and expecting a good radiational cooling set up by Friday morning. Record or near record lows are likely, especially over the northern half of the forecast area with the anticipated fresh snow pack in place. Something to mention in forecast after Wednesday's system. The strong surface high shifts to the Great Lakes area and looks to keep the next 500mb low tracking across Arkansas and Missouri. Ahead of the low, a weak ribbon of vorticity provides enough forcing to keep the mention of rain and snow going Friday night into Saturday. Soundings suggest either rain or snow during the day Saturday with ice introduction present, but there remains a deep layer of dry air to contend with below 800mb to the surface. Thus, QPF and any snow amounts look to be light attm. Sunday into Tuesday...GFS and ECMWF have come into agreement with warmer temperatures by Sunday and tweaked highs up slightly and may need to continue to trend warmer if models persist with this signal. Only caveat is some mid-level clouds across the state. Certainly Monday and Tuesday are forecast to be around normal with highs rising into the upper 50s to 60s, but with the latest MOS guidance from the ECMWF and GFS, highs looks to be even warmer. && .AVIATION.../For the 18Z TAFS through 18Z Tuesday afternoon/ Issued at 1204 AM CDT Tue Apr 17 2018 VFR conditions are in place across the forecast area and are pretty much expected to remain so through the entire period. The only concern would be brief MVFR radiation fog toward daybreak at all sites except KDSM. Precip may also approach KFOD late in the period, but chances and confidence are not there for inclusion at the moment, more likely with 12z issuance and later. && .DMX WATCHES/WARNINGS/ADVISORIES...
