The episode as NWS MEG wrote it up.
A potent upper-level disturbance moved out of the southwest U.S. and into the region during the day on March 25th. The disturbance interacted with an unstable airmass to produce a couple of broken lines of showers and thunderstorms that moved across areas in West Tennessee near the Tennessee River and parts of Northeast Mississippi. There were a few reports of severe weather.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Memphis, TN wrote its last area forecast discussion before the first event at Mar 25, 1:53 PM CST, 27 minutes earlier.
Area Forecast Discussion National Weather Service Memphis TN 253 PM CDT Thu Mar 25 2021 .DISCUSSION... Short term focus is severe weather threat. Storms in the watch areas offer the potential for tornadoes. The forecast area still has a severe weather and tornado threat. Office decision support briefings on social media and SPC Meso discussions offer latest on the evolution into this evening. As the surface system deepens and retreats northeast late this afternoon and evening gusty northwest winds will overspread the western have of the service area. Gusts to 25 to 30 miles an hour are possible, however our sustained winds should stay just below criteria level. After a more quiet day on Friday the front lifts north with thunderstorms expected to develop. Showers and storms persist along the front through Saturday night. There is model uncertainty with this forecast. The ECMWF/Canadian models are depicting more of a stationary boundary that moves south early Sunday as the upper flow becomes more northwest. Meanwhile the GFS/NAM are more bullish with the reinforcing front accelerating and with providing a bit more instability. The area is outlooked for a slight risk of severe weather on day 3, which may seem conditional given the model uncertainty. Later forecasts will help pin point this threat. Regardless, more heavy rainfall seems more certain and the flash flooding and river flooding threat will need to be watched closely. Frontal passage on Sunday will be felt with much cooler air across the region with brisk winds. This drier trend will continue into the beginning of the week. At that point another model discrepancy develops with the Canadian/ECMWF kicking out yet another short from the southwestern US bringing rainfall on Tuesday and Wednesday. The GFS is non-existent with this feature and doesn't bring another rainfall threat until mid-week as all models do with a more powerful cold front. For now have at least some pops for Tuesday respecting the ECMWF/Canadian solutions. Overall the upper air pattern with the upper ridge over the Caribbean and shortwaves ejecting from the southwest appears to make a change later next week. This pattern change may signify a temporary respite from the string of significant rainfall systems. Belles && .AVIATION... 18Z TAFs Main aviation weather impact is TSRA that will likely develop in the TUP vicinity and lift east, and a weaker, likely more brief broken TSRA line lifting through MEM. Nonzero chances of IFR overnight, behind exiting surface front. NAM Bufr soundings depict ground fog, LAV guidance suggests IFR/MVFR ceilings. PWB && .MEG WATCHES/WARNINGS/ADVISORIES... AR...None.
