KalinWhat 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 Jul 29, 6:54 AM CDT, 1 hour 18 minutes earlier. Its key messages:
- More isolated to scattered thunderstorms are expected this evening and overnight mainly along and south of I-90. A few storms could become severe with large hail and damaging winds being the primary threats. Locally heavy rainfall will be a secondary threat.
- Next shower and thunderstorm chances likely occur over the weekend. However, uncertainty remains in the coverage and severity of developing activity.
- Temperatures will trend below normal headed into the weekend with highs mainly in the 70s and low 80s.

Area Forecast Discussion National Weather Service Sioux Falls SD 654 AM CDT Tue Jul 29 2025 .KEY MESSAGES... - More isolated to scattered thunderstorms are expected this evening and overnight mainly along and south of I-90. A few storms could become severe with large hail and damaging winds being the primary threats. Locally heavy rainfall will be a secondary threat. - Next shower and thunderstorm chances likely occur over the weekend. However, uncertainty remains in the coverage and severity of developing activity. - Temperatures will trend below normal headed into the weekend with highs mainly in the 70s and low 80s. && .DISCUSSION... Issued at 350 AM CDT Tue Jul 29 2025 TODAY & TONIGHT: A slightly cooler day ahead! Taking a look at satellite imagery, mostly clear conditions have returned to the area with a few lingering areas of stratus west of the James River. While we could see this area of stratus expand into areas north of I-90 through daybreak, should see most areas break free closer to mid- morning. From here, slightly cooler temperatures are ahead as a combination of northerly to northeasterly surface winds and lingering areas of wildfire smoke aloft keep our temperatures in the 80s to low 90s with the warmest conditions south of U.S. Highway-18. With this and dewpoints in the upper 60s to mid 70s this evening, the stage is set for our next precipitation chances (30%-70%). Looking aloft, isolated showers and thunderstorms likely start across central SD by late afternoon as a mid-level wave traverses the state. As this wave intersects a southward progressing 925-850 mb boundary in the warm sector, should see coverage rapidly expand mainly across areas along and south of I-90 during the evening hours. This developing activity will likely progress to the east- southeast with the boundary and inverted trough during the overnight hours before exiting our area by Wednesday morning. Shifting to the severe risk, while the better shear will be slightly offset from the better instability; there should be just enough co-location along and south of I-90 for a few isolated to scattered strong storms to develop. With plenty of instability (2000-3000 J/kg) and lapse rates closer to 7-8 degrees C/km, any initial semi-discrete storms will be capable of producing up to ping-pong ball sized hail (1.5"). As coverage expands and things grow more upscale overnight, should see the threat transition to strong winds with gusts up to 65 mph possible. Lastly, 10-12 kft warm cloud depths and PWATs between 1.5 to 2 inches (90th percentile) at times will lead to pockets of moderate to heavy rainfall developing mainly across areas south of Highway-18. With this in mind, if "training" occurs across the same areas over prolonged periods of time, there could be some flash flooding concerns. WEDNESDAY ONWARDS: Heading into the midweek, any lingering shower activity will likely persist through the morning hours of Wednesday before pushing to our southeast. From here, fall-like temperatures are ahead as lingering cold air advection (CAA) and easterly to northeasterly winds keep our temperatures locked into the 70s through Thursday. As upper-level ridging builds into the northern plains by Friday, our precipitation chances west of Highway-281 will increase over the weekend as a stationary boundary gradually progresses into our area. While the severity of this activity remains uncertain at this time, decided to leave the default NBM pops in for this period. Lastly, we'll likely see the cooler string of temperatures continue through at least Sunday with highs mainly in the 70s to low 80s && .AVIATION /12Z TAFS THROUGH 12Z WEDNESDAY/... Issued at 640 AM CDT Tue Jul 29 2025 VFR conditions with occasional MVFR to IFR conditions will be possible this TAF period. Taking a look at satellite imagery, MVFR to IFR stratus continues to fill in along a Gregory, SD to Marshall, MN line this morning with pockets showers and thundershowers. Expect this developing activity to persist through the mid to late morning before dissipating. From here, we'll likely see the shower and thunderstorm chances increase from the late afternoon through the overnight hours which will promote MVFR to IFR ceilings/vsbys at times. Otherwise, light northeasterly winds will continue across the area today to end the TAF period. && .FSD WATCHES/WARNINGS/ADVISORIES... SD...None. MN...None. IA...None.
