The episode as NWS MEG wrote it up.
A very warm, moist, and unstable airmass was in place across the Mid-South ahead of an approaching cold front. Dewpoints ranged from 75 to 80 degrees across the area. As the cold front sagged south, an upper-level disturbance pushed into the region, causing an increase in shear. Convection developed along an old outflow boundary during the late afternoon and evening hours on June 18, 2025. Additional development occurred as the front and additional outflow boundaries pushed south into the area. Storm mode was generally clusters and segments at first. Robust instability and high DCAPE values supported large hail and damaging winds initially. After midnight and during the early morning hours of June 19, 2025, the front nearly stalled and became parallel to the upper-level flow. As a result, convection became more east-west oriented with very heavy rainfall rates. Training storms caused significant flash flooding over parts of West Tennessee.

NWS Memphis, TN wrote its last area forecast discussion before the first event at Jun 18, 1:35 PM CST, 3 hours 5 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Memphis TN 235 PM CDT Wed Jun 18 2025 ...New DISCUSSION, FIRE WEATHER... .KEY MESSAGES... Updated at 235 PM CDT Wed Jun 18 2025 - A cold front will push into the region tonight, bringing a couple of rounds of strong to severe storms. A Slight Risk of severe weather is in effect for east Arkansas, the Missouri Bootheel, West Tennessee and extreme northwest Mississippi through the overnight period. - Strong to severe storms will continue across north Mississippi into mid morning on Thursday. - Hot and humid conditions will develop late week, with heat indices above 100 degrees by Saturday. && .DISCUSSION... (This evening through next Tuesday) Issued at 235 PM CDT Wed Jun 18 2025 Currently...A very warm, moist and unstable airmass is in place across the Mid-South ahead of an approaching cold front located roughly along the I-44 corridor in MO. An old outflow boundary sits from NW TN into east-central AR. Dewpoints range from the mid to upper 70s with even some 80 degree readings along the KY/MO border. MLCAPEs range from 2500 to 3000 J/kg across the entire region. 0-6 km bulk wind shear is fairly weak attm with most of the Mid-South below 25 kts. Isolated convection is started to pop up thanks to surface heating though it should remain below severe limits for the next few hours. The next upper level disturbance will push into the region late this afternoon into this evening. This will result in an increase in wind shear with 0-6 km values topping 30 kts in places. The latest hi-res models show development along the old outflow boundary late this afternoon into this evening along with additional development as the front sags into the area overnight. Storm mode is trending toward clusters and segments through much of the night. Given the amount of instability and DCAPE values around 1000 J/kg the main threat will be damaging winds though large hail may accompany some storms. The environment does not seem particular conducive to tornadoes with weak UH tracks though 0-1km helicity values greater than 100 m2/s2 could support a tornado so do not want to completely discount that threat. Later tonight as the front basically stalls and becomes parallel to the upper flow, the convection becomes more E-W. This seems to happen initially just north of the TN/MS state border around 3 am with the line eventually sagging south through north MS into mid-morning Thursday. Precip water values of 1.8 to 2.0 inches across the area will result in some very heavy rainfall rates at times overnight. Any storms that train over the same area could result in an isolated flash flood threat. Upper ridging will build into the region through the end of the week with heat and humidity building. Heat index readings will top 100 degrees by the end of the week and then 105 degrees this weekend. Heat advisories will probably be needed. The heat will continue into next week as latest models indicate upper level high pressure over the SE US. && .AVIATION... (18Z TAFS) Issued at 1239 PM CDT Wed Jun 18 2025 Confidence still remains low with respect to timing and coverage of convection during the TAF period. Hi-res guidance now suggests that this afternoon will largely remain free of convection except for some scattered storms over north MS. Between 22-00Z, convection will develop along a SW/NE boundary in NE AR and north TN. This activity will shift southeast through 03Z. At that time, additional convection will develop as the front moves into the northern portions of the area. The latest guidance doesn't show 2 distinct rounds of convection, instead just has scattered thunderstorms around for much of the overnight hours. The convection will then shift into north MS after 12Z with gradual clearing skies and more westerly winds for the day on Thursday. && .FIRE WEATHER... Issued at 235 PM CDT Wed Jun 18 2025 A cold front will move into the region tonight bringing widespread showers and thunderstorms overnight into tomorrow morning. Hot and humid conditions will move in Friday through the weekend with temperatures rising into the lower to mid 90s. There are no fire weather concerns in the near future as humidities and fuel moistures remain high. && .MEG WATCHES/WARNINGS/ADVISORIES... AR...None. MO...None. MS...None. TN...None. && PUBLIC FORECAST...SJM AVIATION...KRD
