The episode as NWS PAH wrote it up.
A few small clusters of intense thunderstorms tracked eastward across northwest Kentucky during the night. One of these clusters produced wind damage in Henderson County. The storms occurred ahead of a surface low pressure center over west central Illinois. A surface boundary extended southeast into the lower Ohio Valley. Despite loss of daytime heating, the storms maintained their intensity with the aid of a 500 mb jet streak that rotated into the base of a trough over southeast Missouri.

Area Forecast Discussion National Weather Service Paducah KY 1249 AM CDT Mon Aug 7 2023 .UPDATE... Issued at 1243 AM CDT Mon Aug 7 2023 ...AVIATION UPDATE... .SHORT TERM...(Tonight through Tuesday night) Issued at 406 PM CDT Sun Aug 6 2023 The hi-res models are coming into better focus for this evenings' storm risk. The southern storm path is expected to primarily move through Arkansas into Tennessee with minimal chances in southern portions of Missouri and Kentucky. The northern system will pose a more substantial concern for the I-64 corridor this evening. A tornado watch has been issued through 10pm including the northernmost counties of Southern Illinois. Low pressure in Southeast Iowa is dipping southeastward this evening through the overnight hours. Westerly winds at 700mb increase in St. Louis during the evening and cross the Quad State overnight. These increasing winds will help increase shear potential this evening with 0-3 km SRH peaking around 3z. CAPE around 1500-2000 J/kg is plenty sufficient though lower than other recent events. Initial supercell structure northwest of our area is likely to become more organized during the evening. Hail and tornado concerns are tilted earlier in the event while more linear structures this evening would favor damaging wind as the primary severe weather hazard. A few models bring storms further southeast into northwestern Kentucky (especially the NSSL for late afternoon, which at this point is unlikely) while most track storms through the I-64 corridor. Aside from a narrow swath in Wayne and Edwards counties, most of this region has avoided the torrential rains from the past week so flooding issues should be limited. A cold frontal passage tonight will bring an end to much of the precipitation, dropping highs to the lower half of the 80s Monday. The lone concern for rain tomorrow will be from wrap-around showers and storms on the northeastern periphery of the forecast area. Drier air moves in dropping lows Monday night to the lower 60s. Dry conditions are expected Tuesday with highs nudging slightly warmer. Showers from the next system reach Southeast Missouri late Tuesday night. .LONG TERM...(Wednesday through Sunday) Issued at 406 PM CDT Sun Aug 6 2023 Models agree on fairly zonal flow driving a shortwave trough through the Quad State region sometime between Wednesday and Thursday. The Canadian ensemble is faster in progression of the shortwave while the ECMWF is the slowest. The best chances for storms appear to be Wednesday afternoon through Wednesday night. While PW values don't particularly stand out at this time, the Integrated WV transport does, at the 99.5th percentile Wednesday night from the NAEFS ensemble despite being several days out. Instability remains the lesser ingredient with a late return to southerly flow keeping temperatures on the cooler side while also resulting in PW percentiles being below IVT percentiles. Nonetheless, with plenty of shear and moisture advection fueling storm potential, SPC has a day 4 slight risk over most of the Quad State, fairly rare for a risk area that far out this time of year. Lingering PoPs remain with this system into Thursday, a time duration that might be reduced as the timing comes into better focus. A chance of showers and storms is in the forecast for Friday and Saturday as models generally agree on a northern system that may not make it this far south, and some amount of smaller scale southern development which might not make it this far north. Temperatures are forecast to be below normal this week, particularly for the highs which are forecast to be in the 80s throughout. && .SHORT TERM...(Tonight through Tuesday night) Issued at 406 PM CDT Sun Aug 6 2023 The hi-res models are coming into better focus for this evenings' storm risk.

Issued at 1243 AM CDT Mon Aug 7 2023 Convection ahead of a frontal boundary is sinking east-southeast overnight. Uncertainty exists in how far south it will develop into west Kentucky. Current expectations are it will largely move out by 09z though. Winds become WNW tomorrow with sustained winds increasing to 12-14 kts and gusts of 18-22 kts expected. MVFR cigs are depicted to expand southeastward into the cwa during the morning, mainly impacting KMVN and possibly KEVV. Locations further south should remain low VFR. A few light showers may occur during the day. Skies clear by evening as winds slacken off and become light/variable by the end of the period. && .PAH WATCHES/WARNINGS/ADVISORIES... IL...None.
