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 Apr 25, 6:21 AM CDT, 1 hour 57 minutes earlier.
Area forecast discussion, Apr 25, 6:21 AM CDT, 1 hour 57 minutes before
Area Forecast Discussion National Weather Service Sioux Falls SD 621 AM CDT Wed Apr 25 2018 .SHORT TERM...(Today and Tonight) Issued at 419 AM CDT Wed Apr 25 2018 System moving through Nebraska gradually shifting southeast and will take precipitation with it early this morning and clouds by mid to late morning. Behind this system mild air and light winds are expected with highs in the 60s. As high pressure at the surface drifts southeast a southwest flow will develop in central SD and could provide a touch of enhanced mixing. So bumped highs a degree or two and lowered dew points a little, but for now the fire weather concerns should not be high as winds will remain light. A cool night ahead as winds turn south and weaken ahead of a weak system. This system will bring an increase in clouds late tonight and a very small chance for showers. Low level dry air will be a challenge to precipitation development but sprinkles and some light showers will be possible late tonight into Thursday morning. Lows should be in the mid 30s to lower 40s. .LONG TERM...(Thursday through Tuesday) Issued at 419 AM CDT Wed Apr 25 2018 A cooler and windy day is expected on Thursday behind the exiting system. North winds will gust to 35 mph in the afternoon and dew points will dry out. Not quite warm enough or dry enough to warrant a significant fire weather concern, but will be a day to watch out for. High generally in the 50s and lower 60s. Friday will see any residual cool air in the low levels flushed out as a westerly low level component develops. Will likely be a touch breezy but with a lot of sunshine and temperatures in the 60s it will not be as noticeable. Strong upper level ridging will spread across the Northern Plains Saturday into Sunday and provide some welcome warmer weather to the area. Saturday will be the cooler of the two days as some low level cooler air erodes through the day. Still anticipating highs into the 60s with winds generally below 15 mph. A much stronger southerly gradient will develop on Sunday with gusts of 35 to 40 mph possible. Depending upon the speed of the return of the low level moisture a potentially dangerous fire weather day will be possible with the current forecast of 30 to 40 percent afternoon relative humidity. Sunday night into Tuesday the upper level ridge begins to break down and shift east as a trough deepens over the western United States. This should bring a decent chance for showers and thunderstorms as pieces of energy lift north and interact with the low level boundary. Right now models are hinting at enough instability to support isolated severe storms but still too early to be overly concerned. Barring any daytime showers and thunderstorms highs should be in the 70s Sunday through Tuesday with lows in the 50s. && .AVIATION...(For the 12Z TAFS through 12Z Thursday morning) Issued at 617 AM CDT Wed Apr 25 2018 Sunny skies and light winds prevail during the daylight hours today. This evening, high clouds will begin to filter into the region ahead of a cold front which arrives Thursday morning. Little precipitation is expected with this front, but a wind shift, gusts to 25 kt, and mid-level cloud decks are expected Thursday morning. && .FSD WATCHES/WARNINGS/ADVISORIES... SD...None.
