The episode as NWS JKL wrote it up.
Strong winds developed ahead of a frontal boundary and strong area of low pressure. Wind gusts of up to 40 to 50 mph were experienced in the Bluegrass region and higher terrain of far eastern Kentucky. Isolated damage occurred in Letcher County near Mayking as a strong gust flipped a carport.

NWS Jackson, KY wrote its last area forecast discussion before the first event at Jan 10, 7:30 PM EST, 45 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED National Weather Service Jackson KY 730 PM EST Tue Jan 10 2017 .UPDATE... Issued at 730 PM EST TUE JAN 10 2017 00z sfc analysis shows a tight pressure gradient over the area from a deep low pressure center moving through the Great Lakes and high pressure along the East Coast. This is prompting south to southwest wind gusts of 30 to 40 mph across eastern Kentucky - mainly on the ridges - with even higher speeds possible in the most elevated terrain near the Virginia border. For all this, a Wind Advisory is in effect through 10 pm est for the entire JKL CWA. Look for the winds to settle down a bit later in the evening and continue to diminish through the rest of the night. A band of light to moderate showers will continue to press east through the area this evening before stalling and allowing the showers/stray thunderstorms associated with the actual cold front to catch up and overtake eastern Kentucky. Have continued the slight chance of thunder into the overnight hours from this. For temperatures - readings are rather mild throughout the area - running in the upper 40s to lower 50s while dewpoints are generally in the mid to upper 30s east and upper 30s to lower 40s west. Have updated the grids to reflect the latest timing on the showers and stray thunderstorms, as well, as adjusting the near term T and Td grids per the latest obs and trends. These grids have been sent to the NDFD and web servers. && .SHORT TERM...(This evening through Wednesday night) Issued at 322 PM EST TUE JAN 10 2017 The afternoon surface analysis shows a surface low continuing to deepen, as it continues to eject into the western Great Lakes. Meanwhile a cold front resides along the Central and Southern Mississippi River Valley with thunderstorms forming across Southern IL and SE MO. Ahead of the cold front is a strong LLJ at the 850 and 925mb levels in a area of tightening pressure gradient. This will keep the region gusty through the evening hours till the core of the LLJ moves NE of the region. Most the short term guidance has this happening about around 03Z and therefore will keep the NPW going at this stage of the game. The precip ahead of the cold front still looks to be related to the strong LLJ pulling moisture into the region in a more top down saturation scenario. This line of showers and perhaps a thunderstorm will progress across the region this evening through tonight, with again overall good agreement with the latest short term models. It is possible the second line developing across IL/MO catches up to the downstream line we are seeing in west and central KY. Given the chance of seeing measurable precip went definite POPs and only slight on the Thunder. The reason for that is the models are struggling to show much if any elevated instability, but the strong jet alone could lead to a few rubbles. That said, kept the slight thunder going this evening into tonight. This boundary that comes through this evening will hang up across the Tennessee Valley tonight into early Wednesday. The actual cold front slows and only makes it just SE of the Ohio River by Wednesday morning. Therefore POPs become more difficult to nail down, but this should all lift north by Wednesday Afternoon ahead of next lee side low. The question is will this lead to any thunder at all and right now leaning away from that. Just not sure we will see enough instability and SPC keeps the general thunder west of the region as well. The POPs will wane through the evening, as boundary moves north of the region. Matter of fact the SE portions of the CWA could very well dry out before wavering baroclinic zone moves slightly closer to the region. There is still some uncertainty how much if any POPs would be seen given the placement of the better lift. Therefore blended POPs will be fine in the slight to chance CAT at this point. .LONG TERM...(Thursday through Tuesday) Issued at 416 PM EST TUE JAN 10 2017 An unsettled and overall warm period will be in store from late week into next week. A split flow pattern will be in place with cyclonic flow migrating through eastern Canada and the northern United States, while an upper level low digs across California toward Baja. An upper high parked across Florida and the southeast portion of the country looks to keep the heaviest rainfall axis northwest of much of eastern Kentucky, likely lining up somewhere near the Ohio River Valley. However, positioning of this axis remains variable given several passing disturbances and lingering subsequent frontal forcing. Surface low pressure sliding northeast out of the Missouri Valley into the Great Lakes Thursday may allow for a few showers locally in the warm sector, prior to an upper low plowing through Ontario and sending a cold front into eastern Kentucky Thursday evening/night. This will bring a better chance for rain showers through Friday as the front hangs up across the region downstream of another wave migrating northeast of the Baja cutoff low. Following anomalous warmth with high temperatures in the mid 60s Thursday, a cooldown will be in store for Friday behind the front with highs topping out in the low-mid 40s for most locales with low-mid 50s south of Hal Rogers Parkway/Highway 80. A warm front will then lift through the Tennessee Valley and eastern Kentucky Friday evening and night on increasing west/southwest flow. This will lead to another widespread round of rainfall as opposed to any mix with freezing rain as a substantial warm nose develops. Still expecting surface temperatures to mostly remain above freezing as well given surface ridging sliding eastward across the Great Lakes, therefore keeping the brunt of the cold dome north of eastern Kentucky. Warm air/moisture advection should quickly bring temperatures back above freezing in the northern Bluegrass region Friday night if they do indeed drop below freezing beforehand. Rain chances will continue through the weekend into next week as passing northern stream energy combines with the previous cutoff low finally tracking northeast. Well above normal temperatures will continue, until a cold front pushes through sometime early-mid next week pending evolution/movement of the looming upper low. && .AVIATION...(For the 00Z TAFS through 00Z Wednesday evening) ISSUED AT 645 PM EST TUE JAN 10 2017 VFR conditions are holding on over eastern Kentucky early this evening, however an MVFR deck resides just to the west and is approaching. This will move into the Bluegrass and Lake Cumberland regions early this evening from forcing ahead of an cold front that remains further out to the west. This is all leading to a tight pressure gradient along with a strong LLJ in place across the region. Therefore, winds will be gusty through the early evening at most sites. The highest gusts will generally be at LOZ/SME/SYM with lesser ones expected to the east. Winds are expected to peak at 25 to 30 knots at least with locally higher values possible for the next several hours. These winds are expected to lessen through the rest of the evening. Then they will remain out of the south and southwest through the TAF period even as they diminish. Showers will progress deeper into the area through the rest of the evening from west to east. Will also keep a mention of thunder in the TAFs for the late evening and most of the overnight hours. MVFR conditions and continued chances of rain then last into the day Wednesday. && .JKL WATCHES/WARNINGS/ADVISORIES...
