MGWhat 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 Sioux Falls, SD wrote its last area forecast discussion before this river flood warning went out at May 13, 6:57 PM CDT, 42 minutes earlier.
Area forecast discussion, May 13, 6:57 PM CDT, 42 minutes before
Area Forecast Discussion National Weather Service Sioux Falls SD 657 PM CDT Sun May 13 2018 .SHORT TERM...(This evening through Monday) Issued at 305 PM CDT Sun May 13 2018 The short term forecast continues to feature widespread cloudiness and chances for showers with a few rumbles of thunder. Best chances for showers and storms remain to our south closer to the surface boundary but a few could still sneak into our southern and southeastern zones, where there is enough elevated instability for perhaps a marginally severe storm if there happens to be a storm. Without much in the way of a pressure gradient to speak of, winds will continue to be light. As winds go nearly calm over northwest Iowa overnight, could get some patchy fog in that area thanks to moisture from recent rainfall. With a repeat of last night on tap in terms of cloud cover and wind, have held lows above consensus. Winds will become northerly Monday, with clouds beginning to decrease in coverage by sunset. Still, held highs just below consensus as significant clearing will likely wait until Monday night. While the best chances once again remain to our south and southwest, yet another shortwave will drive a slight chance for showers and storms across much of the CWA Monday afternoon and evening. Progged thermodynamic profiles reveal enough elevated CAPE for thunder but overall instability profiles are skinny, so am not expecting severe weather, even south along Highway 20. .LONG TERM...(Monday night through Sunday) Issued at 305 PM CDT Sun May 13 2018 Upper low stuck over the western CONUS will begin to break down by the middle of the week, with subtle mid level ridging expected by Wednesday. The result will be a welcome respite from the cloudy conditions and rain chances and high temperatures likely in the 80s. Upper level flow becomes quite slow over the central United States by the end of the week with divergent model solutions bringing various shortwaves across the region. Multiple periods of chance PoPs are warranted. More potent upper level wave looks to drive a frontal passage Friday night into Saturday, bringing the highest chances for showers and storms of the extended forecast with it. This frontal passage has trended slower in recent model runs, so timing is still too uncertain to advertise a specific period with likely PoPs unfortunately. && .AVIATION...(For the 00Z TAFS through 00Z Monday evening) Issued at 657 PM CDT Sun May 13 2018 A fairly widespread swath of MVFR ceilings will continue near and south of Interstate 90 this evening, with expansion overnight of the area slightly northward as well as lowering of ceilings toward IFR along with developing MVFR to locally IFR visibilities across mainly northwest Iowa and the immediate Missouri River areas. The best chance for convection will be through the lower Missouri River corridor by very late night and early morning, but limited mention of any thunder from the elevated instability near KSUX to just a couple of early morning hours. Northerly flow will increase later in the day, and should begin to progress a trend toward VFR conditions southward into KFSD during the afternoon. Will also mention a small chance for thunder late in the TAF period for KFSD with presence of weak convergence at lower levels. && .FSD WATCHES/WARNINGS/ADVISORIES... SD...None. MN...None. IA...None.
