What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, 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 this severe thunderstorm warning went out at Mar 27, 1:54 PM CDT, 29 minutes earlier.

Area forecast discussion, Mar 27, 1:54 PM CDT, 29 minutes before

Area Forecast Discussion
National Weather Service Paducah KY
154 PM CDT Mon Mar 27 2017

.SHORT TERM...(Tonight through Wednesday night)
Issued at 138 PM CDT Mon Mar 27 2017

Near term convective (svr) environment continues, with best
threat area appearing now to be shifting to Lakes/eastward across
southern Pennryile, where best dew point surge/area of some
breaks/highest MU Capes coexist. Area of ongoing convection has
picked up steam, from around 32Kts earlier today to ongoing around
40Kts now, and this is anticipated as upper jet is moving in.
This should propel convection thru southern Ky fairly quickly,
with HRRR modeling the ongoing activity reasonably well, and
taking bulk of its pcpn thru the area/into scntl Ky/cntl Tn by
23Z. Will go near certainty Pops til then, and cut into them
drastically afterwards. May maintain upper trof/instability shower
chance or slight chance, esp east, overnight however.

After tonight, Tuesday offers a pause, with the upper ridge
nudging across the mid Mississippi/Tennessee valleys. Then another
robust storm system takes shape and ejects across the southern
Plains, moving its convection into the lower and mid Mississippi
valleys Wed night-Thursday, with maybe some warm sector/advection
chances showing up earlier, esp west, during the day Wed. A
similar environment is encountered so we are outlooked SWODY3
Marginal to Slight risk for late Wed night into Thursday morning,
with the 15% bubbling across western Ky Thursday, not too
dissimilar to Today.

.LONG TERM...(Thursday through Sunday)
Issued at 256 AM CDT Mon Mar 27 2017

Models are in better agreement on the track of our late week surface
low, taking it from southwest Missouri into central Illinois then
into the southern Great Lakes region.  Both the ECMWF and GFS have
it around the St. Louis area around 00z Friday, with the Canadian
about 6 hours slower.  This track and general timing has the
associated cold front moving across the PAH forecast area late
Thursday into Thursday night.  Along and ahead of the front, models
produce widespread precipitation Thursday into Thursday night, and
went with likely to categorical pops for showers.  Based on the
expected track of the low, we should have better instability across
our region, so increased thunderstorm possibilities from slight
chance to chance during the day Thursday, with slight chances into
Thursday evening.  Lingered some slight chances of thunder in our
eastern counties late Thursday night until the front moves east of
our area. Showers will taper off from west to east on Friday.

Surface high pressure centered north of the PAH forecast area and a
weak upper level ridge over the lower and middle Mississippi Valley
will give us dry conditions Friday night into at least early
Saturday night.  Models show an upper low moving toward the region
on Sunday and included some chances for showers.

South winds ahead of the cold front will give us unseasonably warm
temperatures Thursday into Thursday night.  Cooler air will filter
in behind the front, and daytime highs will return to near seasonal
for Friday through Sunday, with overnight lows still a few degrees
above normal.

&&

.AVIATION...
Issued at 138 PM CDT Mon Mar 27 2017

Convective chances with associated restrictions should be moving
out by next issuance time, until then, strong storms are possible,
esp KPAH/KOWB. Overnight, parent upper trof moving overhead will
keep unsettled MVFR CIGS and MVFR VSBYS may occur at times as
well. Tmrw should see generally improving flight conditions,
though CIGS may be maintained early, until diurnal heating can
erode/lift cloud bases to VFR.
