The episode as NWS OHX wrote it up.
A mesoscale convective system (MCS) developed and tracked southeast through Middle Tennessee during the afternoon of June 9, 2026. With abnormally high amounts of atmospheric moisture, these thunderstorms were able to produce very heavy rainfall with rain amounts of five to seven inches reported across portions of Sumner and Robertson counties. This caused flash flooding for these areas, particularly in low-lying areas and those along area creeks. This MCS also produced severe thunderstorm winds which downed several trees and caused other minor damage before it weakened across southern Middle Tennessee.
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 Jun 9, 12:22 PM CST, 2 hours earlier. Its key messages:
Area Forecast Discussion National Weather Service Nashville TN 122 PM CDT Tue Jun 9 2026 ...New KEY MESSAGES... .KEY MESSAGES... Updated at 119 PM CDT Tue Jun 9 2026 - There is a low to medium chance for severe weather this afternoon and evening, mainly north of I-40. Strong winds are the primary threat. - Localized flash flooding from heavy rain will remain a possibility through tonight. - Hot and humid conditions build as heat indices reach the 100s west of the Plateau Wednesday and Thursday. && .SHORT TERM... (Rest of today through Wednesday) Issued at 1113 AM CDT Tue Jun 9 2026 Middle TN remains in a moisture-rich environment, though PWATs have actually dropped a touch this morning, down to 1.90". Still well above the 90th percentile climatologically, but it's lower than previous days. For the remainder of today, our eyes will be just to our north along the TN/KY border as another MCV spins through this evening. Embedded within this MCV will be the potential for very heavy rain and gusty winds. Bulk shear will increase out ahead of this, lending to strong wind threat. Shear values overall are forecast to be on the lower side, between 20-25 kts, but with tons of instability in place from daytime heating, it won't take much for a storm to get windy this afternoon/evening. Timing for potential severe storms will be this afternoon through tonight before 12AM. With regards to the flooding threat, the Flood Watch has been cancelled since widespread flooding is no longer a concern. As storms move through this afternoon and evening, localized flash flooding will remain a possibility, so remain aware of that if you get caught under a storm. Rain and storm chances will becomes much more isolated Wednesday as high pressure expands to our west. This feature will bring warmer temperatures into the upper 80s to low 90s, and coupled with continued high humidity, this will result in heat index values in the upper 90s to low 100s. && .LONG TERM... (Wednesday Night through next Tuesday) Issued at 1113 AM CDT Tue Jun 9 2026 High pressure will remain in place through Thursday, which will be our hottest day this week with air temperatures in the mid 90s and heat index values in the low 100s. By Friday, a front will push through the area, bringing a high chance for rain and storms areawide. The severe threat with this front currently look very low with only meager bulk shear values. Still, there will be plenty of instability from daytime heating for the front to interact with, so we could see a few strong storms. Moving into the weekend, upper level flow will become more zonal with high humidity remaining in place. There is some model uncertainty beyond Saturday, but the pattern overall favors continued low to medium rain chances through early next week. Long range models are hinting at a very deep low developing over the Great Lakes next week that would help keep our temperatures cooler, in the low to mid 80s. && .AVIATION... (18Z TAFS) Issued at 1232 PM CDT Tue Jun 9 2026 The HRRR is consistent in bringing a cluster of storms southeastward into Middle Tennessee during the afternoon, so we've added PROB30 groups to the TAFs to account for this possibility, with the impact times staying close to the HRRR timing. After that, TAFs are VFR, except for some morning MVFR ceilings at KCSV. && .PRELIMINARY POINT TEMPS/POPS...
