The episode as NWS LMK wrote it up.
Scattered thunderstorms across the eastern Bluegrass Region produced a westward moving outflow boundary. Isolated storms developed along this boundary, including one small cell just east of Lexington. This cell remained stationary during its hour long life and dumped around 2 inches over an area only a few square miles in size.
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 Louisville, KY wrote its last area forecast discussion before the first event at Sep 4, 2:27 PM EST, 1 hour 33 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LOUISVILLE KY 327 PM EDT Thu Sep 4 2014 .SHORT TERM (Now through Friday Night)... Issued at 309 PM EDT Thu Sep 4 2014 An axis of higher theta-e and low-level PWATs is currently streaming across eastern KY and providing a focus for the convection that has fired up there. The bulk of the precip has remained outside of this forecast area but pop-ups have occurred across the eastern border and into the Bluegrass region. Any convection that remains in the area this afternoon/evening will dissipate after the loss of daytime heating. Partial clearing of the skies can be expected but cirrus is expected to begin invading from the NW by early Friday. Some mid-level clouds are also anticipated to move in and will assist in hindering morning fog but with plenty of low-level moisture remaining in place and light to calm winds, some patchy fog is still expected to develop, especially in the east where rain has fallen today. Deterministic models are largely keeping south-central IN and central KY dry on Friday but given the moisture expected to advect in with southwesterly flow well ahead of the approaching cold front, along with decent instability to work with, have decided not to remove mentionable PoPs for tomorrow. Isolated thunderstorms will be a possibility with increasing chances as Friday night approaches. General model consensus has the front laid out across southern IN by late Friday/early Saturday and will provide a focus for increased storm chances. The warmest temperatures for the next week will be occurring in the short-term period. Highs tomorrow will reach the upper 80s to around 90 degrees, even with cloud cover in the area. Lows tonight and tomorrow night will only drop into upper 60s and lower 70s, which has been the norm as of late. Dewpoints will be about the same, keeping the RHs up until the fropa. .LONG TERM (Saturday through Thursday)... Issued at 315 PM EDT Thu Sep 4 2014 The cold front progged to usher in a pattern change is still on track to cross the area early Saturday with on and off showers and storms likely through the day Saturday. As previously mentioned, forcing along the front will be weakening as it becomes well displaced from its parent low pressure system over southeast Canada. Thus no organized severe threat is anticipated at this time. If any threats were to accompany convection Sat, it would be a minor flooding threat with PWATS in the 1.7-1.9 inch range and slow storm motions. Convection should clear the area Sat evening with sfc high pressure building in behind it for Sun. Sunday will feature much lower humidity with high temperatures only reaching the mid to upper 70s. This will be a welcome first taste of the fall season! Cooler temperatures (highs in the upper 70s/low 80s and lows in the upper 50s and 60s) will stick around through the week with perhaps another shot of cooler air toward the end of the work week. As far as precipitation chances for next week, the pattern looks to hold multiple upper level shortwave troughs. The 12Z guidance seems to be somewhat in agreement that the first would bring showers/storms to the area mainly on Tues with another perhaps more potent shortwave trough to arrive by Wed night/Thurs. Therefore will continue on and off 20-40% POPs for mid week next week. && .AVIATION (18Z TAF Update)... Issued at 123 PM EDT Thu Sep 4 2014 Diurnal CU field has blossomed across central KY early this afternoon and will linger through this evening. With plenty of moisture and instability to work with across southeastern KY and into the Bluegrass region, showers and thunderstorms have popped-up. There will be a tight cut-off of where precip will be possible with that line in the vicinity of LEX. Given how close convection has developed (within 10-15 miles), have included VCTS for this afternoon at LEX since it is possible convection could fire up much closer to the terminal. SDF and BWG, while there could be some towering CU, looks to remain rain-free through early tomorrow. Lower-level clouds should partially clear out after sunset tonight at all three terminals but cirrus should begin to penetrate central KY by early Friday morning in anticipation of the next system/frontal passage (which is outside of the scope of this TAF period). While there will be lower-level moisture around overnight tonight, clouds and the lack of rain at BWG and SDF should keep fog conditions from dropping too low (i.e., higher end MVFR or VFR). Have kept LEX on the lower end of MVFR but if rain does fall within the area there this afternoon, then IFR conditions could be possible there, despite the clouds forecast. The CU field will once again develop by early in the day on Friday as continued warm, moist conditions persist under southerly flow. && .LMK WATCHES/WARNINGS/ADVISORIES... KY...NONE.
