Forecast update
Issued at 1049 am edt Sun aug 25 2019
12z raobs show southerly flow at the low and mid level from the
central gulf coast to the missouri and tennessee valleys, revealed
on IR and water vapor satellite loops as widespread clouds from the
western gulf up through the mississippi valley. Amdar soundings out
of bna this morning show high rh below 700mb. Precipitable water
values have been slowly increasing over southern kentucky as that
moist air pushes northward.

Most of the upper energy will remain off to our west today, but we
do have a surface trough draped across southern and eastern
kentucky. A few small light rain showers have developed in that area
this morning, and coverage is expected to increase after about 1pm
cdt this afternoon as instability rises and we reach convective
temperatures in the lower to middle 80s.

Issued at 625 am edt Sun aug 25 2019
made some minor tweaks to the forecast for today based on the 06z
model runs coming in... Mainly to tighten up the pop gradient along
the i-64 corridor today.

Short term (today and tonight)
issued at 300 am edt Sun aug 25 2019
the second half of the weekend still looks to be "cool", but this
time more because of cloud cover and rains building into the area
from the south. Warm front, currently across the tennessee valley,
will lift northward into our area. As it does so, we'll see moisture
that had been held down to our south lift northward with the front
as well as an increasing southerly flow aloft. That flow aloft comes
from a large upper level low, now swirling over eastern NE as per
latest water vapor imagery.

Despite the cloud cover today, hi-res models show some pockets of
storms developing this afternoon, across southern ky, which could
dump some localized heavy rainfall. Flash flood guidance still is
pretty high, given our recent dry spell. Values in the lake
cumberland area are the lowest, with a little over 2" 3 hours as our
guidance. Still, would not be surprised if we have to issue a flood
advisory or two later this afternoon and tonight down south.

As we get into tonight, precipitable waters rise to near peak values
for this time of year... Spreading the better rain chances throughout
the forecast area. With a saturated sounding, there likely will be a
few pockets of thunder embedded within the rain shield. Will again
have to watch for higher rainfall totals in these pockets. Still
think the relatively dry period we've come out will help us to
absorb most of this rain well. Forecast average rainfall totals this
afternoon through tonight look to range to be in the 1-2" range in
our bwg area counties, with lower values to the north and east.

Those are averages though, and again a potential exists for much
higher amounts.

Long term (Monday through Saturday)
updated at 355 am edt Sun aug 25 2019
the week ahead is best defined not by temperatures, which will be at
or below normal through the period, but by moisture, which will do a
flip from a rainy start to the week to a dry finish.

A broad upper level trof will provide the energy for the rainfall
during the first part of the week, which will be ongoing Monday
morning to start the period. The bulk of the rain will fall in two
main waves: the first during the day on Monday as a tightening
surface pressure gradient helps send higher dewpoints from the gulf
into the ohio valley. The second shot of heavier rain will occur
just ahead of a cold frontal passage on Tuesday. While thunderstorms
will be responsible for all of the rain, at this time there does not
appear to be a severe weather threat with them - other than problems
resulting from heavy rain that could cause some runoff problems in
isolated locations. In between these two time frames, there will be
a bit of a lull, but lighter scattered showers will still be
possible.

With all of the cloud cover and associated rainfall, the diurnal
temperature range will be reduced, with daytime highs Monday only in
the 70s, and lows Monday night in the upper 60s. Tuesday will warm a
bit more - into the lower 80s - and become more humid as dew points
creep back over 70 thanks to the open gulf and southerly winds in
advance of the cold front.

After the front moves through Tuesday and Tuesday evening, much
drier air will return and put an end to the precipitation as surface
high pressure drifts in from the central plains during the remainder
of the week. Temperatures in the wake of the cold front will top
out in the low 80s, while morning lows will dip into the upper 50s
to lower 60s.

Aviation (12z TAF issuance)
updated at 640 am edt Sun aug 25 2019
the hnb sdf lex terminals should remainVFR at least into the mid
afternoon hours today. Bwg will see better chances for rain by late
morning, with lowering ceilings through the day. Cannot rule out a
rumble of thunder down there later this afternoon, as deeper
moisture continues streaming into the region from the south. By this
evening all sites will see layered clouds in the MVFR to low-endVFR
range... With CIGS continuing to drop in the overnight. A low level
jet could provide focus even for some storms Sunday overnight at sdf
and hnb.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
