Area Forecast Discussion
National Weather Service Jackson KY
135 AM EDT TUE AUG 2 2016

.UPDATE...
Issued at 135 AM EDT TUE AUG 2 2016

Made a few minor tweaks to the forecast grids, mainly to adjust
the timing and eastward track of a small complex of showers and
storms that is currently moving across the souther half of the
forecast area. These showers and storms appear to be moving along
a track that is a bit further south than the inherited forecast
was indicating, so appropriate changes were made to reflect this.
Also ingested the latest hourly obs to establish new trends in the
hourly forecast data. The changes made did warrant issuing a new
zone forecast text product or hazardous weather outlook at this
time.

UPDATE Issued at 1120 PM EDT MON AUG 1 2016

Updated the grids and zone forecast for the rest of the night
lowering thunder chances to just isolated while including the
patchy fog - locally dense. The lingering cluster of convection
just to the west will slowly die out but with the boundary still
in the area will maintain a small chance for convection through
the night. Also, tweaked the T and Td grids per the latest obs and
trends. These have been sent to the NDFD and web servers with an
updated ZFP and HWO to follow shortly.

UPDATE Issued at 845 PM EDT MON AUG 1 2016

00Z sfc analysis shows a washed out frontal boundary across
Kentucky. This contributed to another round of showers and storms
containing heavy rains for this afternoon and lasting into the
evening. Some of the rains were excessive leading to urban and
small stream flood concerns for portions of the area that saw
training of the convection. Places to the west and east of the
CWA seem to have borne the brunt of the heaviest rainfall and
flooding, though. Additional storms continue the over Central
Kentucky and these are expected to translate east through the rest
of the evening before mostly fading out. However, for now will
allow for storm chances to go into the night, though becoming more
isolated after midnight. The grids have been updated with this
thought in mind and in conjunction with the latest HRRR/HRRR time
lag guidance. Did also add a touch of patchy dense fog to the
valleys for later tonight into Tuesday morning, especially for
the spots that saw the most rain. T and Td grids were updated with
respect to current obs and trends. These all have been sent to the
NDFD and web servers.

.SHORT TERM...(This evening through Tuesday night)
Issued at 405 PM EDT MON AUG 1 2016

A stationary front is currently draped from west to east across the
north-central portion of the state. Along this boundary, two MCS's
formed and were moving eastward as of this morning. By noon, the
western most system was falling apart, while the MCS across north
central KY was continuing a strong push eastward. Over the next
hour, afternoon heating and the lift associated with the boundary
began kicking up scattered showers and thunderstorms. As of 3pm,
these showers and storms had become more scattered to numerous
across the northern half of the CWA, merging with the north central
MCS to create a large conglomerate of showers and thunderstorms.
These showers and thunderstorms are expected to continue to develop
and track across the northern half of the CWA along the frontal
boundary through this evening. Our main concern at this point is
heavy rains that may accompany some of the stronger cells, and the
potential for training storms as they move in a west to easterly
fashion.

By this evening, expect best coverage to begin dropping off as we
lose daytime heating and instability. The front will remained draped
across the state, however, and all of the CAMs are continuing to
show masses of showers and thunderstorms continuing across portions
of the CWA. Unfortunately, none of the models have a good handle on
where any of this convection will set up, with each one putting it in
a different location within the CWA. Tried to match up as best as
possible, with better chances in the north during the first part of
the night (coinciding with ongoing conditions), and then better
convection along the southern half of the CWA late as the boundary
drops southward. Given the light winds and significant moisture
across the area, included mention of patchy fog overnight,
especially in the valley locations and along the northern CWA where
some clearing may occur. However, this may actually be a bit
underplayed, as some areal fog cannot be ruled out. Will pass on to
next shift to monitor.

While the frontal boundary axis will drop south and west of much of
the CWA during the day tomorrow, continued moisture and instability
from heating will be enough to promote pop up showers and
thunderstorms by early afternoon, the increasing in coverage,
especially across the far eastern portion of the state, during the
rest of the afternoon. Once we lose daytime heating Tuesday evening,
lack of strong forcing will quickly cut off convection. Kept much of
Tuesday night dry as a result, although some of the CAMs are
spitting out some very isolated convection, spawning from moisture
which is wrapping around the high sitting off to our west.
Confidence was too low in this to include mention of pops during
this time, but may be something to watch. As for temperatures,
expect near or just above normal values through the short term
period. Winds will be light and variable as well.

.LONG TERM...(Wednesday through Monday)
Issued at 342 PM EDT MON AUG 1 2016

We start off the period in the periphery of a upper level high
centered across the Southern plains states. Then a upper level low
drives east into the northeast US and will bring slightly lower
heights for the weekend. The models are in decent agreement with
the overall upper level pattern based on spaghetti plots. However
no strong surface signals exist till we get closer to the weekend.
The other issue in terms of POPs in this pattern will be potential
for MCS activity. Therefore will stick with the model blend which
would lead to slight chance storms generally through Thursday
given the mesoscale nature of MCS. Then by the weekend a frontal
boundary is expected to dive south and will become the driver for
convection over the weekend. At this point, models are in decent
agreement with the boundary then becoming quasi stationary by
Sunday. Right now the blends are going with chance POPs Saturday,
but would expect the blends will continue to increase as
continuity increases. The PWATs are also expected to increase aoa
2 inches into the weekend leading to potential for heavy rain with
any storms that develop. After this think chance POPs will
transition south and stay there late weekend into early next week.
That said will keep most spots in slight chance just given the
airmass. Temperature through the period will become slightly above
average with highs topping out in the upper 80s to lower 90s.

.AVIATION...(For the 06Z TAFS through 06Z Tuesday night)
ISSUED AT 135 AM EDT TUE AUG 2 2016

Scattered showers and a few thunderstorms will be affecting the
taf sites at JKL, LOZ, and SME through around 8Z this morning. The
strong storm at this time will be moving across SME and LOZ
between 6 and 8Z, and will bring brief heavy downpours and cloud
to ground lighting with it. Conditions at SME and LOZ will
fluctuated between VFR and IFR while the showers and storms move
through, and should settle to IFR between 8 and 12Z as the rain
slacks off and fog sets in. The airports at SYM, SJS, and JKL will
likely see periods of IFR to LIFR conditions due to fog over the
next several hours, before conditions improve to MFVR around sun
rise and then VFR once the fog dissipates by 13Z. Isolated to
scattered showers and storms will remain a possibility at all the
airports through around 23Z on Wednesday.
