The toll

Deaths: 0
Injuries: 0
Property damage: $55,000
Crop damage: None recorded

Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.

What happened

The episode as NWS PAH wrote it up.

A small cluster of severe thunderstorms moved southeast, producing locally damaging winds and hail. The storms occurred along a warm front that extended from central Illinois southeast into northwest Kentucky. The storms occurred during the warmest and most unstable time of day, when surface-based capes were near 2,000 j/kg.

What forecasters said that day

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 May 10, 1:31 PM CST, 3 hours 9 minutes earlier.

231 PM CDT Thu May 10 2018

.SHORT TERM...(Tonight through Monday) Issued at 220 PM CDT Thu
May 10 2018

Highest chances for isolated to scattered thunderstorm activity in
the short term will come late this afternoon and this evening as a
weak mid level trof drifts ene out of southern MO and into the mid
MS River Valley. There still seems to be very little support from
the lower levels as far as any boundaries or convergence areas,
and over all moisture remains marginal with PWs running 1.2 to
1.4 inches. However, we are beginning to see some mid 60 sfc dew
points in the MO Bootheel this afternoon, and a swath of 2000-2500
J/KG CAPEs has developed out along and just east of the MS River
ahead of the mid level impulse. Therefore, will continue with at
least some isolated to scattered storm chances in those areas this
evening, until instability has a chance to wane and the mid level
trof progresses east.

12Z model consensus still has an mid/upper level ridge building
over the region as we head from Friday into and through the
upcoming weekend. The ridge will likely persist through Monday as
well. Southerly breezes near the surface will combine with ample
sunshine to push afternoon temperatures to near record levels each
day Friday through Monday. In addition, winds 15+ MPH
Friday/Saturday may require another Lake Wind Advisory in some
areas. Highs in the upper 80s to around 90 Friday/Saturday may
build into the lower 90s by Sunday/Monday, with increasingly
uncomfortable humidity levels creeping in as well.

.LONG TERM...(Tuesday through Thursday)
Issued at 230 PM CDT Thu May 10 2018

By Tuesday, model consensus suggests the mid/upper ridge will
shift farther east toward the East Coast, and gradually allow our
flow to become more swly aloft. This will lead to increasing
moisture and better chances for diurnal convection to develop.
In addition, a low pressure system lifting north out of the
northeastern Gulf will probably add some extra moisture to the
equation with time. Thus, by mid week, scattered thunderstorms
could become much more prevalent. Expected weak flow aloft,
however, should preclude much of a strong/organized storm threat.

.AVIATION...
Issued at 1223 PM CDT Thu May 10 2018

Prevailing VFR conditions and moderate winds are expected through
the rest of the day under some mid and high cloudiness. An
approaching disturbance from the west may aid in the development
of showers and thunderstorms later this afternoon and early this
evening, mainly north and east of a Carbondale to Madisonville
line, added thunder mention to EVV/OWB given this. Potential is
marginal but sufficient for TAF mention, will monitor through the
afternoon and amend if necessary. Light and variable winds
overnight will pick up into somewhat gusty southwest winds in the
late morning Friday gusting at 17 to 21 kts.
