Severe Thunderstorm Warning 211, NWS Louisville, KY

Area Forecast Discussion
National Weather Service Louisville KY
304 PM EDT Sat Aug 31 2019

.Short Term...(This evening through Sunday)
Issued at 300 PM EDT Sat Aug 31 2019

An unstable airmass exists just north of a stationary boundary over
central KY.  Also a weak mid level disturbance passing through the
region is providing some wind shear enhancement for potential storm
development late this afternoon and evening.  CAMs still indicate
the best focus for storms will be roughly from Louisville to
Lexington and points north of that line.  Steep low level lapse
rates and DCAPE of 900-1000 j/kg exist which could produce strong to
damaging winds in the strongest storms.  Decent 0-6 km bulk shear
and 1500-2000 j/kg CAPE could also result in small hail.  In
addition to gusty winds and small hail, any storm this
afternoon/evening could produce brief heavy rain and cloud to ground
lightning.  Storms are expected to diminish by late evening.

Tonight, expect partly cloudy skies with some patchy fog development
late.  Low temps should range from 63-69.

For Sunday, a mid level impulse will again spark afternoon/evening
showers and storms mainly over southern Indiana/north central KY.
Soundings indicate a few strong storms are possible with gusty winds
and brief heavy rain.  High temps on Sun should reach the upper 80s
to around 90.

.Long Term...(Sunday night through Saturday)
Updated at 300 PM EDT Sat Aug 31 2019

The upper-level trough will begin to push eastward out of the area
on Monday. As we remain in northwest flow, a few isolated showers
and storms are possible Monday, mainly in the Bluegrass region, with
some moderate instability (MLCAPE ~ 1000 J/kg) in place. By Tuesday,
the western ridge will expand across the region, keeping us dry and
sunny. An upper-level low is then expected to traverse across Ontario
and Quebec on Wednesday, pushing an elongated cold front through the
Ohio Valley. Scattered showers and storms will be possible ahead of
the front, although with relatively dry mid-levels in place due to a
lack of moisture from the Gulf, PoPs are being held to the 15-20%
range. Highs Monday through Wednesday will be in the upper 80s to
lower 90s. Cooler air will then move in behind the front, resulting
in pleasant weather for the end of the week. Highs will remain a few
degrees below normal Thursday and Friday, with temps in the upper
70s and lower 80s.

.Aviation...(18Z TAF Issuance)
Updated at 130 PM EDT Sat Aug 31 2019

Mostly VFR conditions are expected for this TAF period.  A
stationary boundary over KY this afternoon will provide focus for
showers/storms near SDF/LEX with lesser chances at HNB.  Coverage is
expected to be widely sct at best so will stick with VCTS/VCSH.
There is some light fog potential for tonight if skies can clear.
The best chance is at HNB so included an MVFR BR group from 9-13Z.
Light ESE winds today will be light/vrb or calm tonight, and then
turn more southerly for Sunday.
