.Forecast Update...
Issued at 545 PM EDT Sun Aug 5 2012

Pressure pattern, dewpoint discontinuity, and northern edge of the
cloud field show the cold front draped across southern Indiana.
However the wind shift just north of the Western Kentucky and
Bluegrass Parkways has made itself known as the effective boundary,
with scattered storms firing up along it. Other storms have popped
west of Bowling Green in the air mass that has had a chance to
destabilize.

A few storms have built up tall enough to produce gusty winds, but
the main threat this evening will be torrential rainfall and an
excessive amount of cloud-to-ground lightning. Still keeping tabs on
the far southern counties, where the heaviest rain fell earlier
today. If storms can come together into a solid line upstream, will
have to give strong consideration to a Flood Watch in those areas.

Gridded forecast has been updated for precip trends, but the lower
resolution text products can ride as-is.

.Short Term (Tonight through Monday night)...
Issued at 255 PM EDT Sun Aug 5 2012

At 18Z a cold front stretched from Toledo to Evansville to Little
Rock and was pushing very slowly to the southeast.  Despite day-long
clouds and showers, LAPS analysis showed that some surface
destabilization has managed to occur, and convection is still
expected to develop ahead of the front late this afternoon into this
evening.  The main threat with any storms continues to be heavy
rain.  Locally heavy rain has already fallen today so the storms
will have to be watched for any water problems.  As of this writing
though it looks like there will be several hours time between the
earlier heavy rain and any additional rain this evening, and the
heavy rain earlier today was spotty.  So, will hold off on a flash
flood watch for now, but will monitor closely.

In addition to heavy rain this evening, the strongest storms may
manage to produce some gusty winds and small hail.  However, the
soundings show so much deep moisture that the chance of large hail
making it to the surface appears slim, and gusty winds will be
primarily reliant on precipitation drag rather than dry air
entrainment.

Lows tonight will range from around 60 in the north to 70 along the
Tennessee border.  Patchy fog may develop, especially in areas where
heavy rain falls.

Monday the front will weaken and get hung up over the Tennessee
Valley.  As a result, some scattered storms will still be possible
in southern Kentucky though no severe weather is expected.  Highs
across the region will be in the 80s with light winds.

Weak ridging will attempt to build in from the north Monday night to
dry the entire region out.  It will also bring us pleasant lows in
the 60s.

.Long Term (Tuesday through Saturday)...
Issued at 230 PM EDT Sun Aug 5 2012

Little has changed with regards to the forecast for the long term
this afternoon. Surface high pressure will remain over the area
Tuesday through Wednesday. This should help keep storms confined to
mainly eastern Kentucky. Though a few models do show a stray shower
or storm creeping into the Lake Cumberland area Tuesday afternoon,
will keep the forecast dry as it looks like the chances for any rain
are small. High temperatures Tuesday - Wednesday will range from the
upper 80s to lower 90s with lows in the upper 60s to lower 70s.

A deepening trough will slowly swing across the Great Lakes Thursday
through Friday. A cold front associated with this system will move
through the region sometime late Thursday night through Friday.
There is still some disagreement in the models as to how fast this
front will move through. Regardless, scattered thunderstorms are
expected to develop in the unstable environment ahead of the front
Thursday afternoon. Storms are also expected to accompany the
frontal passage itself on Friday. These should be moving out by
Friday evening/early Saturday.

Temperatures will be challenging on Thursday and Friday and will
depend on the cloud cover and precipitation. Thursday still looks to
be in the upper 80s. However, Friday should see some more rain and
possibly cooler air filtering in behind the front. Will go with
highs in the mid 80s. Saturday will be even cooler with temps
topping out in the lower to mid 80s. Lows will be in the lower 70s
Friday morning, dropping back to the lower to mid 60s by Sunday
morning.

.Aviation (18Z TAF Issuance)...
Issued at 111 PM EDT Sun Aug 5 2012

At 17Z the cold front was about midway between Louisville and
Indianapolis, slowly moving to the southeast.  Showers and
thunderstorms are still expected to develop this afternoon ahead of
the front, though very little has developed so far upstream from the
terminals. As a result, will stick with VCTS for now, during the
most likely times for storms to be near the airports.  The main
threat from the storms will be very heavy rain and gusty winds.

As the front moves through central Kentucky late this afternoon and
this evening it will take its precipitation along with it.  Winds
will be light and variable behind the front and some fog will be
possible late tonight.

Tomorrow the cold front will get hung up over the Tennessee Valley
and may give southern Kentucky some scattered showers and storms,
but the best chances will be after this TAF period and primarily at
BWG.
