Area Forecast Discussion
National Weather Service Louisville KY
253 PM EDT Sat May 23 2020

.Short Term...(This evening through Sunday)
Issued at 230 PM EDT Sat May 23 2020

Watching widely scattered storms popping up across the region.
Latest GOES sounder data indicates fairly uniform instability across
the region this hour, and current Kentucky Mesonet shows the
available moisture across the region well...with dewpoints around
70! Such a change from the rest of this year so far. Would expect
current storms to lay down some outflow boundaries that will help
new storms to develop through the rest of the afternoon. As is the
case with a pulse thunderstorm environment, most hi-res guidance is
not initializing well, so have been advertising scattered storm
chances. As has been mentioned before, shear is fairly weak, so main
concern will be with the stronger updrafts and subsequent
downdrafts. DCAPEs are fairly high per latest SPC mesoanalysis...so
still calling for a few storms with damaging wind gusts.

As we get into the evening hours, expect storms to dissipate...but
the mugginess will remain. South winds around 5 mph should help to
keep any fog formation to a minimum, but cannot rule out a brief
period with patches of fog this evening in the wake of any early
evening storms.

Sunday we reload somewhat, with shear remaining fairly light.
Instability may end up a little stronger, but the question mark will
be triggers to take advantage of that instability. For now, have
gone a little less for coverage than with today's rain chances. That
should help temperatures get into the upper 80s for our warmer
spots...with heat indices getting into the lower 90s.  Good summer
weather for the Memorial Day weekend.

&&

.Long Term...(Sunday night through Saturday)
Issued at 245 PM EDT Sat May 23 2020

Unsettled weather looks to prevail throughout the long term, as the
region become situated under a persistent ridging pattern. As such,
expect to see afternoon highs in the mid to upper 80s, with
dewpoints in the upper 60s, causing heat index values to peak in the
low 90s. SW flow during this time will also help funnel juicy Gulf
moisture across the region, resulting in daily chances for showers
and thunderstorms, with the highest chances occurring during the
afternoon/evening hours.

With the upper ridge in place, stronger winds aloft will be
restricted to our west and north, and deep layer shear here will be
weak to moderate, causing the severe potential to be rather limited.
However, it is worth noting that locally heavy downpours, gusty
winds, and small hail may certainly still occur given the
instability in place coupled with PWAT values of 1.5 to 2 inches.
Localized flooding may also become an issue given the recent rains
and saturated grounds. Otherwise, expect overnight lows to be above
climatological norms throughout the week, with temperature forecast
to only fall into the upper 60s.

&&

.Aviation...(18Z TAF Issuance)
Issued at 1255 PM EDT Sat May 23 2020

Atmosphere destabilizing under some good heating. Expect a few
stronger storms to pop up this afternoon, with forecast timing based
on latest satellite/radar imagery and statistical guidance. Should
the core of these scattered storms hit the terminals, they will
bring brief IFR conditions and gusty winds, likely to at least 30
knots. Storms will wind down this evening, with a more uniform
southerly wind becoming established overnight. Expect another round
of widely scattered storms Sunday afternoon.
