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 Mar 24, 6:27 PM CDT, 2 hours 56 minutes earlier.
Area forecast discussion, Mar 24, 6:27 PM CDT, 2 hours 56 minutes before
Area Forecast Discussion National Weather Service Sioux Falls SD 627 PM CDT Sat Mar 24 2018 .SHORT TERM...(This evening through Sunday) Issued at 427 PM CDT Sat Mar 24 2018 Brief quiet period this evening, before warm advection ahead of a subtle mid-level wave starts generating light precipitation in central South Dakota. This will gradually work eastward through the day, but is expected to diminish as it progresses east through the early afternoon. Limited mid-level moisture and generally weak lift should lead to primarily freezing drizzle or drizzle late tonight into Sunday. Could see some light icing in areas west of I-29 prior to temperatures warming up tomorrow morning, but given an expected scattered nature to the precipitation and light amounts, opting to cover this potential in the HWO and via social media and not issue any winter weather headlines at this time. Expecting temperatures in our west to only dip to a degree or two below freezing tonight in these areas, and with daytime road surface temperatures warming well above freezing, impacts may also be confined to elevated/untreated surfaces, even during the early morning. .LONG TERM...(Sunday night through Saturday) Issued at 427 PM CDT Sat Mar 24 2018 Stronger trough will impact the region Sunday night through Monday, and again (possibly even more-so), precipitation type will be highly uncertain. Part of the difficulty is variance among the models in the available moisture below -10C, and thus the potential for freezing drizzle or drizzle as opposed to rain/snow. With this in mind, QPF may be a little too high, but confidence in any one solution is too low to make adjustments to the blended forecast at this time. Given the above-mentioned lack of mid-level moisture, and thermal profiles which nudge above zero across a good portion of the area, periods of freezing drizzle/rain and associated icing are certainly possible. However, as mentioned in the short-term section, any icing impacts, especially during the day, may be limited due to warming road temps. Will try to hone in on the area of greatest icing risk over the next couple of forecast cycles, but for now, will focus on the HWO and social media to heighten awareness of the potential. Beyond Monday night, we get back into a more tranquil pattern. Not completely dry as a cool, broad trough settles over the Plains for midweek, but it appears that any precipitation chances will be scattered and light. && .AVIATION...(For the 00Z TAFS through 00Z Sunday evening) Issued at 626 PM CDT Sat Mar 24 2018 Overall, MVFR is expected for the 00Z TAF period. However with an easterly to southeast fetch of air continuing, it is possible that a little VFR could sneak into KFSD between 06Z and 12Z Sunday. But with warm air advection moving in on Sunday, MVFR ceilings will move back in at KFSD. && .FSD WATCHES/WARNINGS/ADVISORIES... SD...None. MN...None. IA...None.
