.Short Term...(This evening through Tuesday)
Issued at 254 PM EDT Mon Jun 17 2019

Clouds from this morning's rain have partially broken up and have
allowed some destabilization of the atmosphere, with SBCAPE of 2k-3k
J/kg. Cu has some more vertical development today than it did
yesterday at this time, and a few thunderstorms have already begun
to pop. Expect scattered thunderstorms to continue to develop this
afternoon and continue into this evening. While locally gusty winds
and small hail will be possible with the strongest storms, heavy
rain will be the main threat in 1.8" PWAT air and plenty of moisture
showing up on the soundings. One hour flash flood guidance is below
an inch in some spots over southern Indiana and north central
Kentucky.

Scattered storms will decrease in coverage late this evening, with a
lull in activity before showers and storms ramp back up in the pre-
dawn hours and into Tuesday morning as a vort max moves up from the
Tennessee Valley and brings another threat of locally heavy rain.

Instability tomorrow afternoon should be hampered by the morning
rain, but some scattered development should be possible with a broad
east-west surface front still lined up roughly along the Ohio River
and a weakening upper disturbance moving through.

&&

.Long Term...(Tuesday night through Monday)
Issued at 345 PM EDT Mon Jun 17 2019

The long term portion of the forecast should start off relatively
quiet Tuesday night. Flow aloft looks benign with the next wave
still out over the Plains. Can't totally rule out isolated showers
given the very humid airmass, particularly east of I-65. Lows in the
upper 60s will be common.

The weather turns more active once again Wednesday afternoon through
Thursday. A convectively-enhanced shortwave is forecast to swing
through Wednesday night with the upper trough moving through on
Thursday. Low pressure is forecast to deepen to the northeast over
the Lower Ohio Valley Wednesday night, with a nice surge in the SW
LLJ (35-40 kts). The proximity of the sfc low will provide a nicely
veered wind profile, and the mid-level wave will bring a speed max
of 50-60 kts. Instability is more marginal, but the moisture-rich
environment will at least support strong storms capable of
torrential rainfall, gusty winds, and lightning. A damaging wind
threat could certainly develop as early as Wed afternoon and
evening. The primary hazard may be flash flooding, especially with
any training convection. The moisture transport surge in the warm
sector will push PWATs into the 1.7-1.9 inch range, so rainfall
production will certainly be efficient.

The cold front sweeps through, bringing drying conditions Thursday
evening. A dry period will likely continue through Friday and
possibly Friday night. Friday morning lows will dip into the low to
mid 60s. Friday looks like a rare nice weather day with highs in the
80s.

The pattern is more amplified through the weekend, and ensemble
means agree on a 594 mid level ridge developing over the Gulf of
Mexico. At some point this weekend, convection in the Plains and
Midwest will likely spill eastward into our region. And the hot,
humid airmass may support at least scattered convection each day
this weekend into early next week.

.Aviation...(18Z TAF Issuance)
Updated at 113 PM EDT Mon Jun 17 2019

Clouds have broken up early this afternoon and have allowed some
destabilization of the atmosphere. As an upper level disturbance
moves in this afternoon scattered storms will once again develop.
While conditions outside the storms will be mostly VFR, the storms
themselves will be capable of very heavy downpours, brief gusty
winds, and small hail.

The afternoon activity will gradually dwindle late this evening, but
then will ramp back up again during the pre-dawn hours as a
weakening shortwave trough comes in from the west. Those showers and
storms should continue into the daylight hours Tuesday morning and
may bring sub-fuel alternate ceilings.
