The episode as NWS PAH wrote it up.
Strong south winds gusted to between 40 and 50 mph, with isolated higher gusts. The highest reported gust was 52 mph at the Carbondale airport. A deep surface low pressure center moved east-northeast from the Kansas City area to northern Illinois. The strong winds occurred ahead of a surface occluded front that arced southeast from the low. The presence of a mid-level dry slot allowed sufficient solar warming for the stronger winds to mix down to the surface in the afternoon.

Area Forecast Discussion National Weather Service Paducah KY 551 AM CST Mon Jan 22 2018 .UPDATE... Issued at 551 AM CST Mon Jan 22 2018 Updated Aviation Discussion for 12Z TAFs. && .SHORT TERM...(Today through Wednesday night) Issued at 251 AM CST Mon Jan 22 2018 A band of heavy showers with some embedded thunderstorms has entered our western-most counties as of 2 AM. Some bowing segments within the line are currently noted, so can't rule out a strong storm in our far west counties, capable of transferring some of the strong winds aloft to the surface (LLJ starting to ramp up with winds of 55-60+ kts expected at 850mb). Any surface instability resides down in Arkansas, where some stronger convection is currently noted within this band moving eastward. Overall what little elevated instability there is wanes heading into the morning hours. The timing of this convection through the area continues on track, with clearing from west to east from 12z to 18z. A nice dry slot moves in during the late morning and afternoon hours, with breezy conditions and warm temperatures. Nudged highs up a bit closer to MOS guidance, given that we no longer have any snow cover and we will have good mixing during the day. Upper low currently over Kansas will push east into the Great Lakes region by Tuesday morning. Guidance continues to indicate a secondary band of convection developing closer to the upper low later this afternoon, but it should largely stay to our north. May see some wrap around showers on the backside of the low spread into our far northern counties during the evening/overnight hours. Otherwise dry conditions for much of the area after this initial band of convection moves through this morning. Should still have a decent pressure gradient on Tuesday to result in a healthy wind, although winds won't be near as strong as today. Also expecting a good amount of cloud cover on the backside of the system. Temperatures will be quite a bit cooler, back closer to normal for this time of year in the 40s during the day on Tuesday and Wednesday. .LONG TERM...(Thursday through Sunday) Issued at 251 AM CST Mon Jan 22 2018 Thursday into Thursday night continues to look dry with unseasonably warm temperatures as south winds ahead of our next weather system pump warm air north. GFS and ECMWF remain in decent general agreement on the approach and passage of a cold front Friday night into Saturday, though GFS is now about 6 hours faster than the ECMWF. GFS brings the front into western potions of the PAH forecast area by 12z Saturday, and the ECMWF holds off until closer to 18z. The latest ECMWF run is very similar to its 00z run yesterday, and prefer to lean toward its timing due to the consistency. The overall solution indicates showers will spread across the PAH forecast area Friday night, with numerous and more substantial showers expected late Friday night and through the day Saturday, tapering off from west to east Saturday night. Looking at several instability parameters, do not see a reason to include thunder at this time. High pressure will build in behind the front for Sunday, leading to dry conditions. Cooler air will filter into our region, and we should see near seasonal temperatures. && .AVIATION... Issued at 551 AM CST Mon Jan 22 2018 Band of showers and embedded thunderstorms continues to move east across the area, with gusty winds extending out ahead of it. Some IFR/MVFR vsby reductions noted with this convection as well. This activity will continue to end from west to east through late morning. Some MVFR cigs are expected for a short while behind the main band of showers. Main concern through the day will be gusty south/southwest winds of 25-30kts, possibly higher. Some decrease in speed expected this evening/overnight, but still remaining quite gusty. Mid cloud deck creeps back in this evening, with guidance suggesting lowering to low VFR or high end MVFR towards end of period. && .PAH WATCHES/WARNINGS/ADVISORIES... IL...None. MO...None.
