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 Jun 18, 5:51 AM CST, 3 hours 13 minutes earlier.
Area Forecast Discussion National Weather Service Paducah KY 651 AM CDT Sun Jun 18 2017 .UPDATE... Issued at 651 AM CDT Sun Jun 18 2017 The most recent HRRR output takes the band of storms from Carter County through Jackson County east southeast this morning, and has the entire area dry by early afternoon. The latest radar trends certainly support this idea, but not sure if that will be the end of the precipitation or not. The AVIATION section has been updated for the 12Z TAF issuance. &&44 .SHORT TERM...(Today through Tuesday night) Issued at 253 AM CDT Sun Jun 18 2017 With the MCS entering the area and a Watch in effect will attempt to be brief. There appears to be plenty of instability to keep the MCS going across much of the area through daybreak, but not sure if the wind fields will be sufficient to keep the winds near severe levels. We have had a rash of 40-45kt observations just upstream, and hopefully it will stay in that range. Most of the available guidance indicates that the system should be weakening as we head toward daybreak, and the leading line convection certainly looks strongest from northwest Jefferson county northward, while the rest of the line looks rather unorganized. As for the watch we decided to err on the side of caution. It will likely be done well before 9 AM. The 00Z models are quite muddled with the surface pattern later today. The outflow from this system should push through the entire area regardless of the strength of the convection, and the cold front is not very well defined as it moves through our region. The convective debris will make it hard to destabilize today, and with the front not being very sharp/convergent, development may not be as widespread as previously thought, and it may take longer into the afternoon for it to develop. Not sure how much convection we will see and therefore severe storms seem like a long shot at this point. It still looks like it may take most of tonight to get the front and the last of the convection out of the area, but the cooler weather is still on track for Monday. Unfortunately, it will warm up above normal again on Tuesday. .LONG TERM...(Wednesday through Saturday) Issued at 253 AM CDT Sun Jun 18 2017 We will have weak high pressure over the area on Wednesday with dry but warm conditions. It will not feel as humid on Wednesday either with dew points progged to be in the lower 60s This high moves east during the day on Wednesday and into Wednesday night. We continue to watch a system that will be coming onshore in the Gulf. Of course models differ on the track of this system but both the Canadian and ECMWF bring moisture northward into our area Thursday into Friday. This will mean the humid conditions will be returning along with the chances for rain. The GFS shunts the system eastward into the Gulf Coast states and keeps the moisture to our southeast. If the Canadian and ECMWF are correct and that Gulf system or remnants thereof come right up the Mississippi River, we could see precipitation as early as Thursday night. These model differences affect the forecast for Friday as well. However, the GFS does indicate that deeper moisture will infiltrate the eastern parts of the forecast area by Friday. Therefore, we will continue advertising the best chances in the eastern half on Friday given the path of the aforementioned system. However, by Friday night into Saturday, we will be dealing with an incoming frontal boundary from the north. Timing is fairly good between models and good chances for convection44 will arrive Friday night and last at least through Saturday night. Models have been consistent in drying things out Sunday morning into the afternoon. We will see high temperatures a few degrees either side of 90 for Wednesday through Friday, with slightly lower temperatures on Saturday given clouds/precipitation and lower readings on Sunday behind the front. && .AVIATION... Issued at 651 AM CDT Sun Jun 18 2017 It is looking pretty good for a band of thunderstorms over Missouri to push east and southeast across the TAF sites through early afternoon. It may slip just south of KEVV and possibly KOWB, but decided to mention TS at all sites. MVFR ceilings may accompany this activity through the area, but VFR conditions are expected behind the cold front that will move through early this afternoon. Southwest winds may gust into the teens at KEVV and KOWB ahead of the front. Recent rains and light winds along with some clearing possible overnight may result in fog formation. && .PAH WATCHES/WARNINGS/ADVISORIES... IL...None. MO...None. IN...None.
