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 Jul 7, 4:39 PM CST, 23 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LOUISVILLE KY 639 PM EDT Mon Jul 7 2014 ...Updated Aviation Discussion... .SHORT TERM (Now through Tuesday Night)... Issued at 308 PM EDT Mon Jul 7 2014 This afternoon a cold front extended from the Great Lakes through Illinois and Missouri to the Great Plains. Storms have fired ahead of this front, especially between Indianapolis and St Louis in an area of maximized deep moisture convergence and CAPE. These storms will slide to the ESE and will provide southern Indiana and northern sections of central Kentucky with scattered storms this evening. By the time the storms reach here they will likely begin to weaken, so any severe weather that might occur will be isolated. Locally heavy downpours and gusty winds will be the main threats. Tonight an MCS will advance from Kansas/Nebraska this evening into IL/IN/OH early Tuesday morning. The LMK CWA will be on the southern edge of this feature, with showers and a few thunderstorms possible in southern Indiana and northern Kentucky as we're waking up Tuesday morning. Those showers/storms are not expected to be severe. By Tuesday afternoon a line of storms is expected to erupt in the vicinity of the Ohio River. The synoptic cold front, an outflow boundary from the morning MCS, and differential heating will all be possible triggers to get the storms going. We'll also have an upper trof entering the picture from the northwest. Though instability is always in question when we have morning clouds and showers, we should become unstable enough by afternoon such that severe weather will be a threat. Soundings are increasingly showing dry air aloft and bowing echoes are possible, so strong gusty winds will be the main threat. Precipitable water amounts around 2 inches will lead to locally torrential downpours. Tuesday evening the line of strong/severe storms will proceed through central and southern Kentucky. The strongest storms will weakening and move out of the area overnight. Tonight will be muggy, though southwest breezes will keep up around 10 mph through the night to help it feel a little better outside. Lows will be around 70. High temperatures Tuesday will be highly dependent on cloud cover...will go with middle and upper 80s. Tuesday night we'll see rain-cooled lows in the middle and upper 60s. .LONG TERM (Wednesday through Monday)... Issued at 245 PM EDT Mon Jul 7 2014 The synoptic pattern at the start of the long term period will feature rather amplified flow for mid July, with an amplified ridge across the western CONUS and an eastern trough centered over the Great Lakes region. This pattern will slowly deamplify through the long term period, allowing the heat and humidity to return this upcoming weekend after a brief reprieve this week. Wednesday will begin with a cold front pushing southeast of the region. The overall trend in numerical guidance with this front has continued to be quicker, thus think most will remain dry Wednesday as cooler/drier air filters into the region. The only exception may be across southern KY where their proximity to the front may allow for a few lingering showers/storms, mostly during the first part of the day. It will feel quite pleasant, as highs will only top out in the low to mid 80s with reduced humidity values. The pleasant conditions will continue Thursday into Friday as another 1020+ mb surface ridge settles over the region. This ridge will allow for highs in the low to mid 80s Thursday, pushing into the mid and upper 80s Friday. However, both days will still be seasonably pleasant as dewpoints will only be in the upper 50s to lower 60s. The forecast becomes a bit more murky this weekend, as guidance begins to diverge. The GFS is the most aggressive with building an upper-level ridge into the region, which would limit convective activity due to capping aloft. However, the GEM/Euro/GFS Ensemble are in better agreement that this ridge will remain more to the southwest, placing the region in the better northwesterly flow aloft making for a more active period. Will lean towards the more active solution, which brings chances for showers/storms beginning Friday night and lasting at least through the end of the long term period. Temperatures this weekend will be tough given the convective potential, but it will be muggier with highs in the upper 80s to lower 90s. && .AVIATION (00Z TAF Update)... Issued at 635 PM EDT Mon Jul 7 2014 Well...Ongoing convection over EVV to BMG pushing ese and pose a threat to the 3 terminal sites. Bow echo over EVV is heading towards BWG, that is if it holds together. DCAPE values of 1200 will keep the wind threat alive. EVV just measured 57 mph from line. For now have typed up draft WRKTAF will storms moving into SDF by 1z, BWG by 2z and LEX by 3z, but that is highly dependent on if the storms maintain their intensity and characteristics. Tuesday pre-dawn and into the morning daylight hours a large complex of thunderstorms will be advancing from the NE/IA/MO towards IL/IN/OH. SDF, and maybe LEX, will be positioned along the southern edge of this complex. Better storm chances will arrive at SDF Tuesday afternoon, when strong to severe storms will be possible. Winds will once again be gusty from the southwest. Tuesday afternoon event looks probable with high instability airmass with frontal boundary moving into it. The only negative is if there is too much cloud cover from morning convection persists, that would inhibit the deep convection. For now, have predominate showers around 18z and prob30 for tsra. && .LMK WATCHES/WARNINGS/ADVISORIES... KY...NONE. IN...NONE. && Short Term........13 Long Term.........KJD Aviation..........JDG

3 thunderstorm wind. Local standard time, as filed.
Local law enforcement reported several trees down near the town of Deanfield.
A thunderstorm collapsed and the resulting bowing segment knocked down several trees in the Bonnieville area.
A storm survey revealed that a localized downburst with winds estimated between 65 and 70 mph downed numerous trees and power poles in the Lyndon neighborhood east of downtown Louisville. These winds brought damage to a one square mile area centered around the Westport Condominiums. At Westport, several mature trees were toppled, damaging at least 3 vehicles. Nearby, winds damaged a house at the intersection of Washburn and Finley Avenues. A tree fell on a van at the intersection of Westport Road and Herr Lane. The survey recorded 13 power poles damaged and 10 trees downed. Overall, over 10,000 residents lost power.
