$$What forecasters said that day
The local office's own words before this river flood 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 river flood warning went out at Oct 3, 12:28 PM CDT, 2 hours 51 minutes earlier.
Area forecast discussion, Oct 3, 12:28 PM CDT, 2 hours 51 minutes before
Area Forecast Discussion National Weather Service Des Moines IA 1228 PM CDT Wed Oct 3 2018 .UPDATE... Issued at 1218 PM CDT Wed Oct 3 2018 Have been monitoring winds today and tonight with strong WAA winds ahead of the cold front, and then strong, gusty CAA winds expected behind the front this evening and tonight. Mixed layer winds this afternoon continue to show near advisory criteria winds across the central and western portions of the forecast area this afternoon. This looks like it may just allow a few spots to briefly hit advisory criteria and not be widespread or too long in duration. However a stronger signal showing up in far west/northwestern areas by late afternoon with 35 to 40+kts in the mixed layer. Therefore have issued a wind advisory starting at 22z for the far west. Once the front passes, the sfc pressure gradient remains very tight and mixed layer winds continue to show 25-30kts or stronger likely sustained winds, and gusts to 35-40kts or possibly higher through the evening/early morning hours as the cold air surges into Iowa. The CAA and downward motion will aid in momentum transfer of these winds to the surface. Also have very strong sfc pressure rises across the state tonight with around 8-10 mb in 3 hours across western IA by 3z, and around 6-8 mb rises in 3 hours across the central/east by 6z. Therefore have issued a wind advisory for the entire forecast area beginning this evening into the overnight hours. Remainder of forecast components looking on track currently. Only other issue this afternoon continues to be the increased humidity and relative heat across the south this afternoon. Will issue an SPS to at least bring attention to this factor when combined with the wind may cause some issues to those working outdoors or having activities outdoors through the afternoon/early evening. && .SHORT TERM.../Today through Tonight/ Issued at 458 AM CDT Wed Oct 3 2018 Minor changes to mesoscale features, increasing confidence and precision slightly. Otherwise overall general forecast remains the same. A prolonged period of several rounds of moderate to heavy rainfall appear likely the next 7 to 10 days. 08z GOES-R water vapor imagery picking up on numerous upper lows west and north of Iowa through California to Alaska. The upper low that will impact today was located along the Montana/Canada border and rapidly propagating eastward. Models in good enough agreement to have decent confidence in placing this low near the NW Minnesota/Canada border by 21z Wed, and northeast of the Great Lakes by 12z Thu. Our sfc reflection low should be near central Minnesota by 18z, and into Lake Superior by 00z Thu. An attendant cold front is still slated to push through Iowa this evening. Compared to 24 hours ago, the timing of this fropa has trended faster by about 3 hours. The front should be crossing into the DMX CWA by around 00z Thu, and exiting southeast of the DMX CWA shortly after 03z Thu. For Today/This Evening... 3 potentially hazardous weather "threats"- severe wx, heat, and winds. Biggest threat is severe wx, so will address that potential first. As hinted at in yesterday morning's AFD, medium- range models picking up on a weak dryline oriented SSW-NNE ahead of the cold front. The location of this dryline during peak heating looks to be over SW Iowa near Creston to Perry. Shortly after 00z, the rapidly progressing cold front overtakes this dryline, but there may be a window for convection from 21z Wed or so through 00z Thu or so if this weak dryline can be a sufficient lifting mechanism to break the cap. To account for this, have again added thunder chances from Creston through Perry to Des Moines to Lamoni and will watch this area for severe wx potential. Given forecast low- level lapse rates nearing 7 to 8 C/km, large hail will be primary threat. Damaging winds secondary threat, with a non-zero tornado threat in play given decently impressive hodograph, strong helicity, LCL height near to below 1000m. Cold front will have these same threats as well, but instability quickly decreases after sunset, so boundary may not have much juice left by the time it reaches the Waterloo area. Potential for intersecting outflow boundaries from dryline to cold front worth watching as these boundaries could locally intensify storm intensity. Heat and winds should remain below hazard criteria. Winds obviously not purely unidirectional and pressure gradient around 3mb/120km which is not weak, but is not hazardously noteworthy. Heat index values should top out in the mid to upper 80s today. We are not too far removed from summer that there should be special hazard potential with these heat index values. Storms & fropa will rapidly cool temperatures. By Midnight, the temperatures will be in the low to mid 50s along and north of Highway 30, a 25 degree temperature drop in 6 hours. Clear skies will take over through Thursday morning. .LONG TERM.../Thursday through Tuesday/ Issued at 458 AM CDT Wed Oct 3 2018 Thursday Evening Through Friday... The upper low currently off the California coastline makes its journey to the Midwest. By 06z Fri, this wave should be near the Plains. A band of strong 850mb moisture flux convergence oriented from NW-SE surges northward through Iowa ahead of a 35kt LLJ that will bring notable moisture transport into Iowa. PWAT values honing in on the 1.5 to 1.75 range which, as mentioned in yesterday morning's AFD, is a solid +2 to +3 std dev for this time of year. Widespread area of decent enough baroclinic instability With MUCAPE values nearing 500 J/KG, 0-6km mixing ratios 6.0 g/kg, widespread moderate to brief heavy rainfall is likely. Like WPCs QPF forecast of 1 to 1.5 inches overnight more that going forecast in the 0.5 to 1 inch range... have noted this and expect QPF to be increased during this time period in the next few updates. Friday Afternoon through Saturday... 00z GFS and now the 00z ECMWF suggesting severe weather potential, primarily along and south of I-80. 950mb height field picking up on core/height minimums of low in NW Iowa by 21z Fri. Strong 950mb frontogenetical forcing oriented W-E noted along Highway 20, with N- S oriented cold front over west-central Iowa. As is typical with these systems, tornado threat worth monitoring along warm front during peak heating, with large hail and damaging wind threat with the cold front. If this solution can gain run-to-run consistency, SPC will need to increase to a widespread Slight Risk across much of the DMX CWA for Friday afternoon and evening. Saturday... Models begin to digress. A sfc high is slated to push somewhere thorugh the upper Midwest. In yesterday's runs, it appeared this high would bring big dry air entrainment to Iowa, blasting away precip chances. In this morning's runs, especially the 00z ECMWF, this sfc high is pushed northward into Canada and its influence is relegated to NW Iowa. If this scenario plays out, the boundary from Friday's system may stall out over central to eastern Iowa, keeping the state wet. Will monitor. Sunday and Beyond... Models continue with overall synoptic pattern of deep longwave trough through the intermountain west, with multiple upper lows traversing through the Midwest. Strong 850mb-300mb anti-cyclonic flow remains over the east coast, opening up the gulf to several rounds of reinforcing moisture transport through this time period. With boundaries being laid out as focusing mechanisms during various wave passages, several rounds of moderate to heavy precip seems very plausible. PWATs oscillate near the 1.5 inch range during this timeframe, again +2 to +3 std dev. The cumulative effect of these periods of rain may yield widespread flooding concerns across the DMX CWA by the beginning to middle of next week. Grounds are already saturated, so runoff will be high. && .AVIATION.../For the 18Z TAFS through 18Z Thursday afternoon/ Issued at 1218 PM CDT Wed Oct 3 2018 Strong winds will be the largest impact to the 18Z TAF forecast package. Southerly winds at 20 to 35kts will switch to the northwest at relatively the same speed with the passage of a strong cold front between 23Z and 04Z. Cigs mainly lower VFR but may cross MVFR with the FROPA. Expect strong wind gusts with storms. Hail and damaging wind possible with storms as well, especially for the KALO and KOTM terminals.VFR conditions and lower wind speeds out of the north expected after 12Z. && .DMX WATCHES/WARNINGS/ADVISORIES...
