The episode as NWS PAH wrote it up.

Area Forecast Discussion National Weather Service Paducah KY 909 PM CST Sat Nov 14 2020 .UPDATE... Issued at 909 PM CST Sat Nov 14 2020 We collaborated with WFO Memphis to expand the Wind Advisory westward. No change to the valid time. Southern portions of the Advisory will see the strongest winds from the south overnight just ahead of the front, and the northern portions will see the strongest winds from the west Sunday morning. UPDATE Issued at 554 PM CST Sat Nov 14 2020 Updated the aviation discussion for the 00Z TAF issuance. && .SHORT TERM...(Tonight through Monday night) Issued at 239 PM CST Sat Nov 14 2020 The main concerns in the short term forecast period include the chance for strong to severe thunderstorms late tonight and early Sunday morning across roughly the western half of the forecast area and strong gradient winds Sunday across southwest IN, western KY, and southern IL. In the very near term (through 0z Sunday), WAA showers with isolated thunder will continue to spread NE across parts of the southeast MO into southwest IL..along with patchy light showers/drizzle across the EVV Tri- State and NW KY. We should move into a bit of lull early this evening as the WAA showers wind down. The severe threat ramps up late tonight into early Sunday morning across southeast MO and parts of southern IL and far western KY, roughly west of I-57/US 45. Dew point temperatures will surge into in middle to upper 50s ahead of the approaching surface cold front along with temperatures rising into the lower to middle 60s. The 12z CAMs are in a good agreement showing a squall line/QLCS arriving in Carter/Ripley counties around 4-6z Sunday, and racing NE through the forecast area, exiting our eastern counties around 12z. As mentioned earlier, the best threat for some damaging wind gusts and perhaps a couple spin-up tornadoes will be across the western half of the area...particularly in our western four Ozark Foothill counties. This area appears to have the best chance of seeing a few hundred J/kg of SBCAPE developing, collocated with robust low-level shear and elongated hodographs. One fly in the ointment which may prevent a higher end severe threat will be the development of widespread WAA showers/storms ahead of the main line of convection. The line of storms should be progressive enough to prevent widespread flooding issues, but given the cool soil temperatures and leaves clogging up storm drains, can't rule out some minor flooding developing in vulnerable areas. In the wake of the cold frontal passage Sunday morning, winds will crank up from W-NW as the pressure gradient tightens. Current wind advisory area (southeast IL, southwest IN, and the KY Pennyrile) looks to be in good shape. With robust mixing of 40-50 kts 850 mb winds expected, gusts of 40-45 mph seem like a good bet, especially from late morning through early afternoon Sunday. Further south and west, it looks a bit more marginal for advisory-level gusts, but some gusts of 30-40 mph are possible, especially early Sunday morning. Will hold off on expanding the advisory for now, but it may be necessary based on later model trends. High temperatures will reach in the middle to upper 50s, but it will feel colder with the wind. High pressure will build over the region Sunday evening through Monday. This will allow gradient winds to relax and bring a return of dry conditions with seasonable temperatures. Overnight lows Monday morning will fall into the lower to middle 30s with daytimes in the lower 60s. .LONG TERM...(Tuesday through Saturday) Issued at 239 PM CST Sat Nov 14 2020 Broad mid/upper level northwest flow Tuesday will bring a chilly surface high pressure system southeast from southern Canada into the mid MS River Valley, and then into the Ohio Valley Tuesday night/Wednesday. Despite ample sunshine, afternoon temperatures both days will be held in the 50s to near 60 both days. Tuesday night/Wednesday morning should be rather frosty area wide. Thereafter, H50 flow becomes quasi-zonal as the surface high moves east and takes up residence over the southeast US for the latter part of the work week. This should result in a gradual warm up, with temps popping back up well into the 60s Thu/Friday/Sat. && .AVIATION... Issued at 554 PM CST Sat Nov 14 2020 Showers along the I-64 corridor are tracking northeastward at this time. The main feature tonight will be a line of storms along a front, with the line weakening as it moves eastward (thus thunder is not included for the eastern terminals). MVFR cigs are expected with the line. Light to moderate showers will develop ahead of the line during the evening hours. Winds will increase through the evening with a southerly direction, gusting to around 30 kts, shifting to westerly after the front moves through. Before the surface winds pick up in intensity, the evening hours could see low-level wind shear issues at KMVN/KEVV/KOWB. Windy conditions will continue tomorrow, with gusts to around 35 kts for the I-64 corridor and even higher for airspace further north/east. Cloud cover will quickly dissipate a few hours after frontal passage as very dry air moves into the area. && .PAH WATCHES/WARNINGS/ADVISORIES...
