Area Forecast Discussion
National Weather Service Louisville KY
302 PM EDT Sun Aug 6 2017

.Short Term...(This evening through Monday night)
Issued at 352 PM EDT Sun Aug 6 2017

The short term period will be unsettled with a chance for a few
strong storms as well as some minor flooding issues. Currently there
is quite a contrast in weather across the region. An area of light
to moderate rain across portions of central KY and southern IN has
kept temperatures in the mid 60s. Meanwhile, clouds have started to
clear out across far south central KY and mesonet temps down there
have risen into the lower 80s.

Through the remainder of the afternoon into the evening hours, there
should continue to be some clearing and warming across mainly the
southern two tiers of south central KY as a warm front lifts north.
This will allow some instability to develop. Though shear is rather
weak right now, short term models do have it increasing modestly
across southwest central KY through the late afternoon. Scattered
storms are expected to develop again across this region and continue
to increase in coverage into the later evening hours. Though
conditions are not overly favorable, a few stronger storms with
gusty/damaging winds will be possible across this region.

The area of rain further to the north should continue to push to the
northeast and the latest model runs have it weakening and
diminishing in coverage over the next few hours.

For the evening and overnight, the warm front will continue to lift
north into the region as a low pressure system approaches from the
southwest. This low looks to cross central KY during the day
tomorrow. Coverage of showers and storms will increase across the
region tonight. Precipitable water values to rise to near two inches
tonight with the high PWATS remaining in place in the warm sector
across southern and eastern portions of the region tomorrow. Given
the amount of moisture, some ponding of water or localized minor
flooding will be possible, especially across central KY where
showers and storms will linger longer Monday or areas that get
repeated stronger storms tonight.

Precipitation will end tomorrow evening as the low pressure system
moves out. Temperatures through the short term are quite tricky.
They may remain fairly steady across portions of the area tonight.
Highs tomorrow will then be highly dependent on precipitation
coverage and the path of the low across the region. However,
tomorrow night lows should once again dip back into the upper 50s to
mid 60s.

&&

.Long Term...(Tuesday through Sunday)
Issued at 301 PM EDT Sun Aug 6 2017

The long term period will start out quiet with below normal
temperatures and dry weather through at least Wednesday morning. An
inverted trough will then develop across east central Kentucky. This
will result in rain chances creeping back into the forecast for east
central KY Wednesday afternoon through Thursday. However, much of
the region looks to remain dry through this period.

The better chance for rain for everyone will come Friday into the
weekend as a couple of shortwaves move through the upper flow aloft.
At least scattered showers and storms can be expected each day from
Friday through the weekend.

Temperatures will warm up for the latter half of the week. Though
they will still be slightly below normal, it will feel more like
summer weather than it has the last couple of days.

&&

.Aviation (18Z TAF Update)...
Issued at 1255 PM EDT Sun Aug 6 2017

Warm front currently draped across south-central Kentucky very near
BWG, with just enough instability to generate a broken line of
convection on the boundary from BWG westward. All the lightning is
showing up well to the west of the terminal thus far, but with
continued heating it will likely warrant initializing with VCTS and
CB mentions, and NE winds will come around to SE as the front tries
to lift northward.

Less convective character over north-central Kentucky this
afternoon, so will just carry VCSH at SDF and LEX. VFR conditions
will persist as even the CB and strato-cu look to remain scattered,
with a prevailing mid-level ceiling this afternoon and much of
tonight.

Increasing coverage of rain during the night, with a few embedded
thunderstorms, will lower ceilings with the strato-cu filling in
toward morning. Could even go into fuel-alternate for a period of
several hours Monday morning, especially at SDF, but not confident
enough in direct impacts of convection to carry any restricted vis.
