Area Forecast Discussion
National Weather Service Jackson KY
426 AM EDT WED MAY 25 2016

.SHORT TERM...(Today through Thursday)
Issued at 304 AM EDT WED MAY 25 2016

More of the same to report in the short term portion of the
forecast. The model data all still suggesting a warm and muggy air
mass will be in place across the region for the next several days.
Temperatures are expected to run well above normal for the rest of
the week, with day time highs routinely topping out in the 80s
each day. Isolated to scattered thunderstorms will also be
possible today through tomorrow as a weak wave of low pressure
moves from west to east across the Ohio and Tennessee valley
regions. The best time for thunderstorm activity will likely be
from the late morning through early evening hours today and
tomorrow. Winds will generally be from the south at 5 to 10kts
during the day time periods and light and variable tonight. Some
patchy valley fog will be possible early this morning and again
late Wednesday night into early Thursday morning.

.LONG TERM...(Thursday night through Tuesday)
Issued at 426 AM EDT WED MAY 25 2016

Ridging over the southeast conus will be the most influential
feature for our area during the early part of the period.
However, we will be along its periphery, and perturbations in the
westerlies to our north and west may be enough to bring a few
showers and thunder storms at times. The greatest pop will remain
further north and west.

during the weekend, what would appear to be a subtropical low will
move northwest toward the south carolina coast and then slow down.
the gfs and ecmwf still disagree on what happens next. the gfs
inches the low very slowly to the west or northwest, and allows
deep moisture off the atlantic to spiral/pivot well inland over
ky. meanwhile, the ecmwf turns the low very slowly to the
northeast, and keeps the deep moisture to our east. Being that
the system is separated from the westerlies, is handled in
different fashions by the models, and is still at a long time
range, confidence in the actual outcome is low. with the
persistence of the gfs, have allowed for some slightly elevated
pops early next week, but only around 30%, as opposed to the 20%
pops leading up to that time.

.AVIATION...(For the 06Z TAFS through 06Z Wednesday night)
ISSUED AT 150 AM EDT WED MAY 25 2016

VFR conditions expected through the forecast period. Mid level
deck will overspread the area overnight. Could see some patchy fog
in the most sheltered valley locations but not expecting any
influence at area terminals at this time. Winds will be light
until tomorrow when they increase from the southwest at 5-10 kts.
Mostly isolated showers and thunderstorms will move across eastern
Kentucky beginning early this morning and lasting through early
Wednesday evening. These showers and storms should remain
scattered enough to not warrant mentioning in the tafs at this
time.
