555 WGUS63 KMPX 112022 FFAMPX URGENT - IMMEDIATE BROADCAST REQUESTED Flood Watch National Weather Service Twin Cities/Chanhassen MN 322 PM CDT Wed Sep 11 2019 ...EXCESSIVE RAINFALL EXPECTED OVERNIGHT THROUGH THURSDAY... .A Flash Flood Watch is in effect beginning late tonight for much of central and southern Minnesota. This watch includes those counties located along and north of a Windom-Owatonna line, and south of an Ortonville-Scandia line. Thunderstorms capable of excessive rainfall are expected to begin tonight across western Minnesota, and spread across the rest of the watch area during the overnight hours. The heaviest rainfall is expected to fall during the overnight hours, but additional storms redeveloping Thursday afternoon will only exacerbate any flooding issues. Widespread rainfall amounts of 2 to 3 inches are expected by Friday evening across the watch area, with localized amounts of 3 to 5 inches possible in areas where the most stationary bands of thunderstorms set up. Recent heavy rainfall has led to very moist soil conditions and elevated streams and creeks across much of central and southern Minnesota. The combination of high rainfall rates and wet soil conditions could lead to rapid runoff and areas of flash flooding.

What forecasters said that day
The local office's own words before this flash flood watch 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 flash flood watch went out at Sep 11, 12:49 PM CDT, 2 hours 33 minutes earlier.
Area forecast discussion, Sep 11, 12:49 PM CDT, 2 hours 33 minutes before
Area Forecast Discussion National Weather Service Twin Cities/Chanhassen MN 1249 PM CDT Wed Sep 11 2019 .updated for 18z taf discussion below... .SHORT TERM...(Today through Thursday) Issued at 431 AM CDT Wed Sep 11 2019 Storms that came in from the Sioux Falls area overnight sped up as it generated an MCV and encountered stronger steering flow from the LLJ. This ended up limiting our flash flood potential and has held rainfall totals south of the US-212 corridor to generally the 1-2" range. We did get a streak of 2-3" from east of Fairmont up to and through Mankato where a lead cell that moved to the north out ahead of the main line. For today, biggest change with the forecast was to shift everything south. By 00z this evening, both the RAP and HRRR show the warm front still down in northern IA, so agree with what we saw from WPC in shifting the excessive rain outlook south. The setup for tonight looks very similar to what we just saw last night, so another round of heavy rainfall looks likely across southern MN where we are basically getting the rain tonight. With that said, probability matched QPF from the 00z HREF put the heavy rain axis tonight from Redwood Falls over toward the Twin Cities, which is similar to what the 6z HRRR shows. Still with the front remaining farther south through the period, think the 11.00 NSSL- WRF may be on to something with the heavy rain axis down on the MN/IA border. Given the uncertainties on where this second round of heavy rain sets up, have left any decisions on flash flood watches to later shifts when there's hopefully more confidence on where the band of heaviest rain will go tonight. Expect a prolonged lull in precip in the wake of the MCV, so have reduced PoPs quite a bit through the afternoon. Next round of storms look to get going between 0z and 3z to the north of where the warm front ends up. HREF is not overly optimistic on severe potential today, likely due to shortwave ridging in the wake of this mornings activity and our greater severe risk may have to wait until tonight when better forcing and shear arrive. Though by then we will be battling nocturnal destabilization, with severe threat likely diminishing like we saw with the line of storms that went across southern MN last night. For Thursday, the fun continues. This probably looks like our best severe threat day with a cold front advancing across the area, but extensive showers and storms Wednesday night into Thursday morning will limit the amount of destabilization we see. Current SPC Day 3 outlook looks good, though that will depend on timing of the cold front. .LONG TERM...(Thursday night through Tuesday) Issued at 431 AM CDT Wed Sep 11 2019 Big story in the long term is the return of summer for next week as an anomalously strong ridge sets up across eastern NOAM. Thursday evening will see the cold front sweep east across the area and finally end the severe and heavy rain threat. Western WI will have a continuation of severe/heavy rain threat through the evening, but we will have a nice drying trend from west to east. Friday, we did boost wind speeds above the NBM as we will see deep mixing and strong winds develop in the afternoon in the wake of the system moving through Thursday night. West winds gusting 30-40 mph still look likely much of Friday, along with temps holding in the 60s. We will also see some wraparound precip build down into central MN during the morning. This weekend, flow becomes more zonal, but we will see a weak wave swing through the northern Plains Sat/Sat night. We could see storms develop along the cold front Saturday/Saturday night as the GFS has, but the ECMWF bring this front through dry. Stayed with the NBM pops at this point, which has highest PoPs in western WI Saturday evening. Next week, strong upper height anomalies build across the Great Lakes. This will signal a return to summer-like heat and humidity. We stayed with the NBM for temp forecasts next week, but this looks to be conservative, with highs in the mid/upper 80s and 90 or two not out of the question, especially Tuesday/Wednesday. This ridge will also keep us dry, for a few days anyways, with the western trough not looking to head out into the Plains and bring us precip chances until the end of next week. && .AVIATION...(For the 18Z TAFS through 18Z Thursday afternoon) Issued at 1250 PM CDT Wed Sep 11 2019 Weakening upper trough exiting to the east. Some residual FGEN forcing over east central MN trailing into west central WI enough to continue -ra a couple hours or so. IFR/MVFR cigs with next shot of thunder/ra moving into mainly southwest MN after 02z or so. Will time using the current HRRR which seems to have a decent handle of overall expected development. Should lift to east central MN by 08z and then exit into WI in the morning. CIGS look to remain IFR much of Thu morning as well, ahead of surface cold front. KMSP...Residual shra exiting to the east early with next shot of trsa moving in mainly after 08z. May have a break early Thu morning before redevelopment by 17z-18z expected. /OUTLOOK FOR KMSP/ THU night...MVFR/IFR. chc SHRA. Wind SW at 10-15 kts. FRI...VFR. MVFR possible. Wind W at 20G30 kts.
