JPCWhat 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 Twin Cities, MN wrote its last area forecast discussion before this river flood warning went out at Aug 17, 6:17 AM CDT, 3 hours 49 minutes earlier. Its key messages:
- Ongoing line of thunderstorms will lead to localized and/or flash flooding through sunrise.
- Showers and thunderstorms possible this afternoon and evening, with strong wind gusts the primary concern.
- Quiet weather returns after Monday.
Area forecast discussion, Aug 17, 6:17 AM CDT, 3 hours 49 minutes before
Area Forecast Discussion National Weather Service Twin Cities/Chanhassen MN 617 AM CDT Sun Aug 17 2025 .KEY MESSAGES... - Ongoing line of thunderstorms will lead to localized and/or flash flooding through sunrise. - Showers and thunderstorms possible this afternoon and evening, with strong wind gusts the primary concern. - Quiet weather returns after Monday. && .DISCUSSION... Issued at 239 AM CDT Sun Aug 17 2025 An ongoing line of showers and thunderstorms over portions of southern Minnesota has already led to a few Flash Flood Warnings, with rainfall rates exceeding 1 inch per hour in spots with up to 3 inches already on the ground and another 1 to 3 inches possible through the next 4 to 5 hours. High resolution guidance this morning favors very slow northwards movement of the line of showers and storms which is most evident in the western cluster, with showers and storms weakening as the thermal gradient loosens by sunrise. PWATs per RAP/SPC mesoanalysis around 2 inches are present which will continue to fuel the ongoing activity and also keep any severe weather concerns such as hail on the lower end of probability. MUCAPE continues to sit around 2000-2500 J/KG with weak deep layer shear, pointing towards continued slow moving storms with a relatively low risk of severe level threats. Other than a few strong wind gusts, localized and flash flooding are the most likely outcomes from this line of storms alongside the frequent lightning. Redevelopment of showers and storms is possible by midday as daytime heating replenishes instability and shear increases due to the positioning of the surface frontal boundaries ahead of the surface low which looks to move through overnight into Monday. Forcing looks to be relatively weak despite the present of a frontal boundary, mainly due to the de-coupling of the shortwave trough with the upper level jet, with a strengthening low level jet being the primary forcing mechanism overnight. The warm front is expected to lift northwards as the surface low tracks northeast towards central to northern Minnesota by Monday morning, with the cold front stalling over western Minnesota around 12z Monday before moving through during the day. The cold front will present the final chance for showers and storms for the period with better shear allowing for the potential for rotating updrafts unlike the weaker sheared environment that preceded it. By Monday evening, the cold front will be pushing through southeastern Minnesota with the surface low over western WI, ending our shower and storm chances by that point. Tuesday and the days that follow will see northwesterly flow aloft alongside surface high pressure and subsidence, which should keep conditions much quieter compared to the previous few days. Temperatures will remain seasonal in the upper 70s to low 80s with sunshine returning, with the trajectory of upper level winds looking to avoid the worst of the Canadian wildfires which have tarnished some of the potential better weather days over the last month. && .AVIATION /12Z TAFS THROUGH 12Z MONDAY/... Issued at 614 AM CDT Sun Aug 17 2025 Ongoing -RA/-TSRA over RWF/MKT will gradually weaken and move out around 15-16z with redevelopment for all locations generally after 21z. CAMs have struggled to maintain timing this morning with the most recent runs trending later with -TSRA timing later today. MVFR/IFR continues due to CIGs as we will not scatter out until after the -SHRA/-TSRA is done after the end of the period. Winds will be blustery early before weakening, with -TSRA wind gusts potentially required within the TEMPO groups with future TAF issuance. KMSP...Low MVFR should gradually improve with a slight rise in cloud levels through the afternoon, returning to lower MVFR as -RA/-TSRA arrives after 00z. The timing is still uncertain but the TEMPO group from 03 to 07z is the current window for the greatest -TSRA impacts. /OUTLOOK FOR KMSP/ MON...VFR, chc MVFR/-TSRA. Wind S to NW 5-15kts. TUE...VFR.
