What forecasters said that day
The local office's own words before this areal flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Wichita, KS wrote its last area forecast discussion before this areal flood warning went out at Mar 12, 11:47 AM CST, 21 minutes earlier.
Area forecast discussion, Mar 12, 11:47 AM CST, 21 minutes before
Area Forecast Discussion National Weather Service Wichita KS 1147 AM CST Fri Mar 12 2021 .SHORT TERM...(Today through Sunday night) Issued at 302 AM CST Fri Mar 12 2021 Models show increasing low level moisture transport early this morning which should generate scattered to numerous rain showers with some embedded storms today. A few strong storms with hail up to nickel size will be possible mainly this morning due to combination of steeper mid-level lapse rates, strong shear, and MUCAPE values in the 500-1000 J/kg range. Meanwhile the strong storm chances and coverage should begin to diminish during the afternoon/evening as moisture transport weakens. The upper level system over the southwestern states will move very slowly eastward from tonight and reach western Kansas by Sunday. Additional rounds of numerous showers and storms will affect the region from tonight through Sunday. Standardized precipitable water anomalies will rise 3 to 4 deviations above normal which supports higher rainfall rates, and given the longer duration of this signal targeting central Kansas we will expand the flood watch to cover those areas. Widespread 2 to 4 inches with locally higher rainfall totals are likely before this system moves east of Kansas. This will elevate the flooding risk along with rises on many creeks and rivers across the area. Some of the creeks and rivers could experience minor or moderate flooding. .LONG TERM...(Monday through Thursday) Issued at 302 AM CST Fri Mar 12 2021 Medium range models show the upper level system gradually shifting east of Kansas on Monday with some lingering rain possible. Otherwise longer range models show a lull in the precipitation for Monday night-Tuesday. This could be short-lived as another healthy weather system is forecast by GFS model to affect the region for mid- week which could include a possible rain/snow mix over central Kansas. ECMWF model suggests a continuation of dry weather next week with cooler drier air overspreading Kansas. Either solution favors daytime highs being cooler than normal for next week, as the weather pattern keeps the warmer air south of Kansas. && .AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon) Issued at 1127 AM CST Fri Mar 12 2021 Main aviation concern will be storm chances through the next 24 hours. Currently have a strong warm front extending from northeast OK into the TX Panhandle. Strong theta-e advection north of the front in the 850-700mb level resulted in widespread storms this morning over much of the area. The bulk of this activity is now pushing into eastern KS. While we should see a break in the storm activity this afternoon, we should keep light rain/drizzle and low cigs in place all day. Storm activity is expected to increase once again late tonight into Sat morning as 850-700mb moisture transport once again ramps up. Confidence is high that most sites will see a fairly prolonged period of IFR ceilings through Sat. && .FIRE WEATHER... Issued at 302 AM CST Fri Mar 12 2021 Fire weather concerns will remain low across the entire region for several days due to widespread rainfall for today through the weekend. Cooler temperatures will be in store for next week along with more chances of rain by mid-week. && .PRELIMINARY POINT TEMPS/POPS...

Widespread rainfall amounts of 1 to 3 inches is expected for this weekend, with locally higher amounts possible. The rain could be heavy at times, especially during the night time hours on Saturday. In addition, modest to significant rises on area rivers and streams are likely, with some street and low-land flooding also possible. Another weather system could bring more rain chances to the region for Wednesday night into Thursday morning.
