What forecasters said that day

The local office's own words before this special weather statement went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Jackson, KY wrote its last area forecast discussion before this special weather statement went out at Jun 2, 4:29 PM EDT, 1 hour 44 minutes earlier.

Area forecast discussion, Jun 2, 4:29 PM EDT, 1 hour 44 minutes before
Area Forecast Discussion
National Weather Service Jackson KY
429 PM EDT THU JUN 2 2016

.SHORT TERM...(This evening through Friday night)
Issued at 429 PM EDT THU JUN 2 2016

The JKL forecast area remained largely devoid of precip until late
afternoon. This was despite CAPE of 1-2K J/kg and no significant
cap. The issue has been weak forcing/focusing, and the general
scenario should continue. That being the case, it is a low
confidence forecast for precip into tonight. There is still time
for development to occur, and chance pops have been used for the
late afternoon/evening time frame. Think that there will again be
an overall decline in precip during the night.

The weak frontal boundary well north of the Ohio River is
expected to stall and become even more diffuse during the forecast
period. What is left of it should remain nearby, without any
meaningful change in our air mass occurring. That being the case,
we will have a similar scenario for Friday and Friday night.
Convection can be expected for some locations, mainly in the
afternoon or evening, but pinning down the timing and location is
too problematic.

Our precipitable water will remain high (generally in the
1.5-1.75" range) and steering currents will be light. That being
the case, if convection can get going with some minimal
organization, locally heavy rainfall would be a concern.

.LONG TERM...(Saturday through Thursday)
Issued at 350 PM EDT THU JUN 2 2016

The period will be met initially with muggy and unsettled weather,
but we transition to cooler and drier conditions moving into early
next week. Models remain in good agreement with the overall upper
level patterns seen by the spaghetti plots. That said we begin the
period Saturday with the upper level low positioned across the
Western Great Lakes. This trough axis will extend south into the
Southern Mississippi River Valley. This will all couple with weak
waves and defuse front near by to lead to likely pops area wide
Saturday afternoon into early Sunday. Right now severe parameters
are weak, but heavy rain remains the primary threat through the
weekend. This given PWATS remaining in the 1.5 to 1.7 range which
nears plus 2 standard deviations above normal and deep warm cloud
layer with freezing levels near to or greater than 12 KFT. Right
now will hold off on any watches until we see how antecedent
convection shapes up for the rest of the week. The trough will
eventually progress east and sweep the front across the region
later Sunday.

We will then be met with generally broad cyclonic flow aloft for
the remainder of the long term period. This will team up with a
surface high pressure, and continue the trend of cooling
temperatures and drying conditions across the Ohio and Tennessee
Valley regions. The CIPS analog by Wednesday suggest little if any
chance of greater than 90 degree temps east of the Mississippi
River, with even eastern Kentucky seeing little signal for great
than 80s by Wednesday. We do look to eventually warm back into the
80 by the end of next week, as wind come back around to
west/southwest and 588mb ridge builds east.

&&

.AVIATION...(For the 18Z TAFS through 18Z Friday afternoon)
ISSUED AT 234 PM EDT THU JUN 2 2016

Only sparse showers were occurring at the start of the period.
Additional showers and thunderstorms are expected during the
afternoon and evening, but confidence in timing and location of
development is low. What activity there is should go through an
overall decline by later in the evening. Overnight, breaks in the
clouds along with a calm and moist air mass should allow fog to
develop. Most places can expect IFR for a time by dawn. Fog will
dissipate during the morning on Friday.
