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 25, 6:29 AM CDT, 1 hour 28 minutes earlier.
Area forecast discussion, May 25, 6:29 AM CDT, 1 hour 28 minutes before
Area Forecast Discussion National Weather Service Sioux Falls SD 629 AM CDT WED MAY 25 2016 .SHORT TERM...(Today and Tonight) Issued at 352 AM CDT Wed May 25 2016 Corfidi vectors suggest parallel stratiform MCS across the region this morning will shift off to the east. Atmosphere behind the MCS is conditionally unstable, with 2-3K J/kg of surface CAPE developing. Cap becomes fairly minimal by late this afternoon, but still struggling to see how widespread convection could develop with lack of trigger mechanism across the region. Would not be surprised if a storm or two was able to develop solely based on surface heating, but pinpointing that location is difficult. The best chance for this to occur would be across the highway 14 corridor where the capping inversion is slightly weaker, but can't rule out any particular location in the forecast area. If by chance a storm is able to develop, not an overly supportive environment for tornadoes with weak shear in the low levels; however, models suggest steep lapse rates of 9.5-10 C/km along and west of the James River by late afternoon. Therefore, not entirely possible to rule out a landspout out west with initial development in the updraft phase. Elsewhere, think that wind and especially hail will be the primary severe threats. 0-6 km bulk shear vales around 25 knots suggest marginal organization, but think that the large CAPE values due to the steep lapse rates from 700-500 mb will be of greater significance. As for highs today, have lowered highs just a touch with filtered sunshine expected through much of the day. This makes breaking the cap that much more difficult. As heating dies away tonight, atmosphere becomes capped off making the instability difficult to realize. Have kept some 20-30 pops ahead of a weak boundary working through overnight, but with lack of any upper level support, am not sure there will be a lot of convection with the front. .LONG TERM...(Thursday through Tuesday) Issued at 352 AM CDT Wed May 25 2016 Thursday should be a warm day with the environment gradually becoming more unstable with increasing shear. At this time the most unstable air will likely be south of Interstate 90...with what appears to be a good potential for about 2000 to 3000 j/kg CAPE and 30 to 40 knots of surface to 6 km shear. Not a whole lot to say about the Thursday night into Friday night time frame as much of the time will be spent with showers and thunderstorms. Low pressure is expected to deepen across Colorado as low pressure gradually shears out across North Dakota into southern Canada. These two waves will work to keep the low and mid level thermal gradient in place which will help provide additional lift for showers and thunderstorms. While severe weather does not look likely in the immediate area, a strengthening low level jet and strong instability will work north towards far southeast South Dakota and northwest Iowa on Thursday night. This may prove to be the best chance for severe thunderstorms into the weekend. In the outer periods (Saturday through Tuesday), an unsettled weather pattern will continue through the period. Saturday likely to see the best chance for rain and thunderstorms as low pressure lifts northeast. A good chance for a dry Sunday in many locations as subsidence and mid and upper level height rises suggest that precipitation chances will be lower. Troughiness Monday and Tuesday will again support the chance for thunderstorms with warm and relatively humid air expected. overall highs will mainly be in the 70s to lower 80s with lows in the mid 50s to lower 60s. && .AVIATION...(For the 12Z TAFS through 12Z Thursday morning) Issued at 626 AM CDT Wed May 25 2016 SHowers and thunderstorms will continue to shift east of the area this morning.
