The episode as NWS PAH wrote it up.
During the evening, a severe thunderstorm acquired supercell characteristics for an hour or so as it moved southeast across the Lake Barkley area of Trigg County. The storm intensified along a cold front as it pressed southeast across western Kentucky. The atmosphere became sufficiently unstable for the storm to become severe during a short timeframe around sunset. The isolated severe storm was preceded by a round of storms during the morning hours, which produced locally heavy rain. The morning storms were generated by a strong south wind flow of warm and moist air.
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 Paducah, KY wrote its last area forecast discussion before the first event at Feb 7, 5:35 AM CST, 2 hours 37 minutes earlier.
Area Forecast Discussion...UPDATED National Weather Service Paducah KY 535 AM CST Tue Feb 7 2017 .UPDATE... Issued at 535 AM CST Tue Feb 7 2017 Updated the AVIATION discussion for the 12Z TAF issuance. && .SHORT TERM...(Today through Thursday night) Issued at 216 AM CST Tue Feb 7 2017 Above average confidence in the short term due to better model agreement despite multiple chances for precipitation. At the time of this writing, a NW-SE oriented warm front associated with a system over the plains had just lifted to the north and east of our CWA. Short wave energy moving northeast out of the plains will tap into an axis of moist unstable air in place over the area and produce showers and thunderstorms that will spread northeastward through the morning hours. Given the amount of instability, wind fields, mid level lapse rates, etc etc a few storms could become severe with large hail being the primary hazard. Damaging wind gusts as well as a weak tornado or two are not out of the question either. As the morning wears on, the aforementioned system will push/pull a cold front toward the region that is forecast to reach the western sections of our CWA around midday and clear the southeast sections around 9 PM. The airmass ahead of the front will remain unstable and volatile mainly through the morning hours so the threat of severe storms should wind down somewhere in the midday to early afternoon hours. As we get into the 6 AM through midday time frame the primary storm hazards should evolve from large hail to damaging winds as well as the possibility of a weak tornado or two. Coverage of showers and storms will gradually diminish from the west during the afternoon and evening hours with the passage of the front. Wednesday afternoon and evening our CWA may be affected by two weather systems/scenarios. A short wave moving through the broad cyclonic flow aloft may produce light precipitation across our far northern counties, while light overrunning precipitation may develop over the southeast sections due to the aforementioned frontal boundary becoming quasi-stationary just south and east of our area. Models are showing precipitation from these two systems merging/ coming together over the eastern sections of the CWA. High pressure will then begin to overspread the region bringing in cooler and drier air that will prevail through the end of the period. Temperatures through Wednesday will be well above normal, then drop back to near normal or slightly below normal through the rest of the period. .LONG TERM...(Friday through Monday) Issued at 216 AM CST Tue Feb 7 2017 Medium confidence in the extended. Surface high pressure will be in control of the weather Friday. It will be centered over eastern KY Friday morning and move off the east coast by Saturday morning. Circulation around the high will place a southerly flow over our area. This will result in much above normal temperatures. As a matter of fact we will stay much above normal through the extended portion of the forecast. Most areas will even stay above freezing through the extended. We will have a cold front move through Sunday. Warm air advection showers may develop ahead of the approaching cold front on Saturday and Saturday night but would expect them to be light with little impact if any. There are some signs of weak instability Saturday night but will hold off on thunder mention at this point. It looks to be dry again by Monday morning with high pressure once again building into the region. && .AVIATION... Issued at 535 AM CST Tue Feb 7 2017 MVFR cigs early in the period, even in rain showers. Some possibly strong thunderstorm activity will be around this morning, especially south and east of the Ohio River. Strong southerly low level winds aloft will result in some surface gusts to 25 knots through most of the day. This morning cigs/vsbys should continue to improve from the west as well as the ending of SHRA/TSRA. By nightfall gusty winds are expected to veer to the west and subside to AOB 10 knots. && .PAH WATCHES/WARNINGS/ADVISORIES... IL...None. MO...None. IN...None.
