Severe Weather Alert Descriptions

 Dense Fog Advisory  Statement as of 4:15 am EDT on July 25, 2014


... Dense fog advisory in effect until 9 am EDT this morning...

The National Weather Service in Jackson has issued a dense fog
advisory... which is in effect until 9 am EDT this morning.

* Timing... until after sunrise... dense fog will be widespread.
However... the fog will begin to lift and start to dissipate
between 8 and 9 am EDT.

* Visibility... one quarter of a mile or less in most locations and
areas near zero in the valleys.

* Impacts... increased travel times this morning will result from the
dense fog.

Precautionary/preparedness actions...

A dense fog advisory means visibilities will frequently be
reduced to less than one quarter mile. If driving... slow down...
use your headlights... and leave plenty of distance ahead of you.




 Special Statement  Statement as of 12:55 am EDT on July 25, 2014


... Areas of dense fog to affect east Kentucky through the overnight...

The combination of light winds and plenty of moisture in the air is
leading to the formation of dense fog across east Kentucky overnight.
Some locations will see visibility reduced to down around a hundred
feet through dawn. Look for the fog to start to clear up between 8
and 9 am EDT Friday.

Area forecast discussion...updated 
National Weather Service Jackson Kentucky 
720 am EDT Friday Jul 25 2014 


Update... 
issued at 710 am EDT Friday Jul 25 2014 


The fog is holding on strong through The Heart of the County Warning Area while the 
fringes are clearing. Over the far east...along the Virginia border 
the visibilities never got too dense and the web cams are showing 
relatively clear conditions. Have updated the grids to fine tune the 
dense fog and sky cover for the next hour or so before it all starts 
to clear up. Also...tweaked the T and dew point grids per the latest observation and 
trends. The updated forecast has been sent to the ndfd and web 
servers. 


&& 


Short term...(today through saturday) 
issued at 330 am EDT Friday Jul 25 2014 


07z surface analysis shows cool and drier high pressure in control over 
the Ohio Valley and east Kentucky. This has cleared the sky of the 
middle and low level clouds from earlier in the evening. As a result... 
when combined with the moist boundary layer...fog formed early in the 
night and has become dense over much of the area. An Special Weather Statement has been 
issued to address this...though a dense fog advisory appears in order 
judging from the latest observation and web cams. This will be issued with 
the zones and grid package. Otherwise...winds are light through the 
area with temperatures and dewpoints all within a couple of degrees 
of 60. The exception is far northwest parts of the area where there 
remains a dewpoint spread owing to lower levels of moisture. Will 
leave these places out of the dense fog advisory...but mention patchy 
fog in their grids and zones. 


The models are in good agreement aloft through the short term with a 
brief retreat of the eastern trough in the face of the strong western 
ridge flattening out and pushing higher heights east into Kentucky 
through midday Saturday. This will keep the bulk of any shortwave 
activity northeast of the County Warning Area through Saturday morning. However...the 
ridge pulls back later Saturday under the influence of a more 
significant middle level wave that will cross into the western Ohio 
Valley that evening. This wave has been a key one for the past 
several runs that the models blow up with indications of a healthy 
mesoscale convective system. Storm Prediction Center has placed the northern part of our County Warning Area in a slight risk for 
this potential later Saturday night...with damaging winds the 
greatest threat. Given the model similarities have gone with the 
higher resolution nam12 most closely. 


Sensible weather will feature a pleasant day with low afternoon 
humidities and mostly sunny skies...once the dense fog Burns off 
this morning. Although the storm track will stay north of the area 
through midday Saturday...the clouds associated with any convective 
development will likely drift into our area and keep temperatures from 
bottoming out tonight and likely keep fog confined to just the 
valleys. For Saturday...the heat and humidity return to the area 
with a potential for storms by evening...mainly in the north... 
depending on the mesoscale convective system activity to the northwest out ahead of the main 
development anticipated later in the night. 


Again used the consshort as a starting point for temperatures... 
dewpoints...and winds through the first 24 hours and the consall 
thereafter. Did fine tune lows tonight for some small ridge and 
valley differences. As for probability of precipitation...went a tad higher than the MOS 
numbers for Saturday afternoon...and just single digits...in line 
with MOS...until then. 


Long term...(saturday night through thursday) 
issued at 357 am EDT Friday Jul 25 2014 


An amplified long wave trough will be the main weather player during 
the extended forecast. A closed upper level low over NE Canada will 
slowly push southward during the course of the extended 
period...with several shortwaves following the long wave 
pattern...driving our temperatures and precipitation. The first of these 
shortwaves will move into the Great Lakes by Sunday afternoon. At 
the surface...a low pressure system and associated cold front will 
be just ahead of the shortwave...pushing southeast as the shortwave 
progresses. Warm humid and unstable air will filter into the region 
well ahead of the cold front...allowing convection to begin as early 
as 6 to 12z Sunday. It seems as though the latest models are backing 
off on the start time of the precipitation...so the above mentioned time 
has been pushed back slightly from the previous forecast. In good 
news...all the Middle Range models seem to be in decent agreement with 
this system...boosting confidence in this later onset time. 


Looking at the latest forecast soundings...still supportive of a 
possible severe threat by afternoon/evening Sunday...with steep 
lapse rates...cape values 3-4.5 j/kg...strong winds in both the middle 
and upper levels...and drying in the middle levels. Not to mention precipitable water 
amounts will be close to 2 inches /1.93 for Pikeville according to 
the latest NAM/ for a 6 hour period by Sunday afternoon. NAM is 
trending slightly higher on the water content compared to the 
GFS...but both are still concernedly high for possible flash 
flooding threats as well. Storm Prediction Center has also put much of Kentucky and points to 
the east/NE in a day 3 slight risk for severe thunderstorms as well. 


The upper level shortwave will move to Ohio by 12z Monday...while 
the surface front will have pushed southeast of the region. Both drier and 
cooler air will begin filtering in to Kentucky as high pressure moves in 
overhead. However...with the lingering influence of the 
shortwave...as well as some lingering low level moisture...there is 
continued support for some isl/scattered showers and thunderstorms reoccurring 
during the afternoon hours Monday. Once the shortwave finally moves 
well east of the region and drier air continues to take hold...and 
we lose diurnal heating influence...expect any precipitation chances to be 
cut off by Monday night. 


The weather for both Tuesday and Wednesday look great...and very 
unseasonable. The longwave trough...having dropped southward...will 
allow unseasonably cool temperatures to advect into the region. 
While highs Monday will be in the middle and upper 70s...by Tuesday 
they will have dropped further...into the low 70s for much of 
eastern Kentucky. Airmass modification and abundant sunshine will allow 
temperatures to moderate some by Wednesday...but still expect a cool 
upper 70s to around 80. And with surface high pressure still in 
place...and dry nearly winds...precipitation chances will be virtually none. 


Sadly all good things must come to an end. Models start to lose 
agreement this far out in the forecast...but general consensus is 
that some diurnal convection will start to kick back in by afternoon 
Thursday along the highest terrain...as deeper moisture sits to our 
southeast. Then there is the potential for another shortwave to impact the 
region by Friday...bringing more widespread chances for convection. 
Confidence in both of these is still quite low at this point given 
the model consensus...so actually trended the given allblend 
solution lower to only include slight chances at this point across 
much of the region.

Aviation...(for the 12z tafs through 12z Saturday morning) 
issued at 720 am EDT Friday Jul 25 2014 


Dense fog and vlifr conditions are being reported at all the taf 
sites. Expect the fog to start breaking up just after 12z before 
quickly going to VFR with just some fair weather cumulus around 4k feet. 
Tonight some high clouds will arrive and this should limit the 
radiative cooling and conditions conducive to such widespread fog. As 
a result have limited the fog T our valley locations toward the end 
of the taf cycle. Winds will remain light and variable through the 
forecast period.
