The episode as NWS OHX wrote it up.
After a squall line moved through the area on July 18, 2023, another complex of thunderstorms moved through Middle Tennessee early on July 19th. Heavy rain was common with these thunderstorms as they produced three to six inches of rain across the northwest portion of the area. Fortunately, no significant flooding reports were received. Meanwhile, one rogue strong thunderstorm in southern Lawrence County did produce wind damage.
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 Nashville, TN wrote its last area forecast discussion before the first event at Jul 19, 7:24 AM CST, 40 minutes earlier.
Area Forecast Discussion National Weather Service Nashville TN 824 AM CDT Wed Jul 19 2023 ...New UPDATE... .UPDATE... Issued at 824 AM CDT Wed Jul 19 2023 As of 820 AM CDT, clusters of thunderstorms continued along a NW to SE band extending from Missouri down through Middle TN. Locally, the main axis of storms was focused around Waverly and Dickson down to Shelbyville and Manchester. The main issues so far this morning have been heavy rainfall, mainly over our northwest counties. Some spots have received 2+ inches of rain within the past couple of hours. Through the rest of the morning, clusters of thunderstorms will continue to move along the NW-SE oriented low level boundary into our area. So, more rainfall will pile up and additional flood advisories or warnings may be needed, especially in our northwest counties. We have seen some local gusty winds on radar this morning, but the winds could escalate to marginally severe for our west half as a couple of stronger storm clusters from MO/KY dive southeastward. HRRR shows a mid to late morning MCS bringing enhanced winds along and west of I-65, so some areas remain under a severe thunderstorm watch. The forecast has been adjusted for radar and satellite trends. Also, temps have been lowered for most areas with widespread rain/clouds through the morning, then only partial clearing this afternoon. && .SHORT TERM... (Today through Thursday) Issued at 352 AM CDT Wed Jul 19 2023 Showers and isolated thunderstorms moving into northwestern and north central portions of mid state region here over the last half hour or so. CAMs, North American, and Global Models are diverging somewhat on areal coverage of precipitation as day progresses today, but general trend as supported by latest SPC Mesoscale Analysis depicting PW values along with 850 mb Moisture transport vector is to basically have an arc of highest precipitation potential across the north and then diving down through the southeast/southeastern portions, i.e. southern Cumberland Plateau Region, through Thursday. PW values greater than the 90th percentile will continue at least through afternoon hours today. Heaviest rainfall amounts continue to be expected for locations generally around and west of I-24 Corridor and around and north of I-40 Corridor through at least morning hours today in this northwesterly flow pattern aloft supporting of multiple shortwave passages. Will thus continue with Flood Watch through noon time today for above mentioned locations and surrounding counties. Certainly still not out of the question that many areas within the Flash flood Watch could receive in excess of two inches of rainfall, with above mentioned northwest counties having amounts ranging from three inches to locally exceeding six inches. Outside of counties under current Flash Flood Watch, rainfall amounts today could range from one to around two inches. Depending on actual development and progression of storm today, and if any substantial breaks in cloud coverage due occur, allowing diurnal heating influences to come more into play thus increasing CAPE values in 2K J/KG to 3K+ J/KG range, the formation of a few strong to severe thunderstorms can also not be ruled out also with per these localized higher CAPE values, good low to mid level lapse rates, and a little more SRH expected compared to yesterday, with overall potential tornado formation remaining very low, with damaging winds main concern. Main surface frontal boundary will remain across southern Ohio Valley Region through afternoon hours today. Look for that surface front to basically wash out as tonight into Thursday progress with a more well defined surface front approaching the southern Ohio River Valley as Thursday progresses. As a series of shortwaves move across our region, some more substantial than others, isolated to scattered showers and thunderstorms will prevail through afternoon hours today and this evening, with more numerous convection being possible across north central and northeastern portions of mid state region after midnight tonight through morning hours on Thursday. A more of a scattered shower and thunderstorm coverage expected as Thursday afternoon progresses. Again, a few strong to severe thunderstorms will be possible with strong to damaging winds main concern. As for temperatures, with amount of cloud coverage and rainfall expected today, have lowered high temperatures by a few degrees across mid state region. Highs today will actually be a few degrees below seasonal normal values, ranging upper 80s to lower 90s, low to mid 80s for locations just west of and across Cumberland Plateau Region. Although heat index values may be around the century mark TN River Valley Region, not expecting even these locations to reach heat advisory thresholds, so previous concerns of a heat advisory being issued for any portion of our area is now minimal at best. Lows tonight will be mild in this unstable atmospheric environment generally ranging low to mid 70s. Highs on Thursday will once again warm to above seasonal normal values as a surface high pressure influences slightly strengthen across northern Gulf of Mexico region. Highs will generally range low to mid 90s, mid 80s to around 90 for locations just west of and across Cumberland Plateau Region. As for potential of heat advisory products being issued for Thursday afternoon time period, there may be be some locations west of Cumberland Plateau Region on Thursday afternoon that could approach or be around heat advisory thresholds,however with generally scattered to numerous showers and thunderstorms possible during afternoon hours on Thursday, with localized rainfall impacts potentially lowering temperatures for at least a short time during these afternoon hours, confidence not high enough to warrant issuance of any heat advisory products. && .LONG TERM... (Thursday Night through next Tuesday) Issued at 352 AM CDT Wed Jul 19 2023 We start of Friday night with upper-level northwesterly flow as we find ourselves once again at the axis of a synoptic trough. Long range models show a short-wave entering our area on Friday afternoon coinciding with the weak cold front that is expected at that time. GFS shows the cold front entering the northern Tennesse border Friday morning (sometime between 7am-10am) passing through Middle Tennesse from Friday afternoon into the evening. Along this front we should see a good chance of wide coverage of showers and thunderstorms. Once the front passes, it will bring in drier northerly winds overnight into Saturday morning. This would make for the start of a lovely weekend as ensembles show highs in the mid to high 80s and dewpoints in the low 60s. A surface high pressure system is expected to develop over our area on Sunday, warming temperatures a bit and giving us sunny skies. I do highly suggest going out and enjoying this nice weekend, especially as we expect to start seeing gulf moisture return next week. The upper-level high over in southwest CONUS is expected to intensify and tilt 500mb heights above to bring us our usual upper-level northwesterly flow on Monday. This means next week's weather pattern will be determined by short-waves that will provide the lift for our gulf moisture to set up a nice game of wack-a-mole precipitation chances. Pop-up showers and thunderstorms can't be ruled out each afternoon next week. Wednesday seems to show a slight increase in precipitation chances as the surface high pressure to out east moves away with the signs of a cold front possible for the end of next week. It is still too far to be certain, but there seems to be hints of one in the north part of the Ohio Valley. && .AVIATION... (12Z TAFS) Issued at 623 AM CDT Wed Jul 19 2023 SHRA/TSRA will continue to move through the area through about 18Z. Expect periods of decreased cigs/vis with the heaviest storms. Storms will move from NW to SE, impacting CKV first, followed by BNA/MQY. Conditions will improve across the area after 18Z. Winds will remain predominantly from the southwest. && .PRELIMINARY POINT TEMPS/POPS...
