Areas affected...northern Kentucky...far southern Indiana
Concerning...Severe potential...Watch possible
Valid 041630Z - 041900Z
Probability of Watch Issuance...60 percent
SUMMARY...A corridor of scattered damaging gusts or marginal hail
potential exists over much of central and northern Kentucky and
toward the Ohio River.
DISCUSSION...Within a weak surface trough and on the southern
periphery of the earlier rain/outflow, an extremely moist air mass
continues to heat and destabilize. Mid 70s F dewpoints exist along
with GPW PWAT values over 2.25". Meanwhile, strong heating exists
south of the outflow/frontal zone, with warming into the lower 90s
F.
Primarily westerly flow exists across the area, except
west/southwest within the boundary layer. As such, little northward
movement in the existing surface theta-e gradient is anticipated
over the next few hours.
VWPs indicate 35+ kt speeds at 700 mb, with around 50 kt at 500 mb.
As a result, developing robust storms now over southern IN and
western KY are likely to intensify and perhaps expand a bit in N/S
coverage through the afternoon. Ample PWAT to support downbursts,
steepening low-level lapse rates, and favorable low to midlevel mean
wind speeds all support a developing damaging wind threat, and a
watch may be needed.
