Area forecast discussion...updated 
National Weather Service Jackson Kentucky 
358 am EDT Monday Aug 3 2015 


Short term...(today through tuesday) 
issued at 345 am EDT Monday Aug 3 2015 


07z surface analysis shows high pressure still holding on over 
southern Kentucky ahead of a cold front off to the northwest. 
Skies are clear through the County Warning Area and this has resulted in a good 
night of radiational cooling. Accordingly...sheltered valleys are 
running nearly 10 degrees cooler than the ridges with lower 60s 
found in the hollows compared to the low 70s on the hill tops. 
Dewpoints...meanwhile...are generally in the low to middle 6os across 
eastern Kentucky with light to calm winds. No sign of any fog 
yet...but do anticipate shallow and locally dense fog in the river 
valleys toward dawn again this morning. 


The models are in fairly good agreement aloft as they show the 
southward shift in the broad and unseasonably deep low currently 
over east central Canada. This movement will serve to tighten up 
the middle level gradient through the Ohio Valley later today and 
through the rest of the short term. East Kentucky will be in 
northwest flow with ripples of minor waves passing through into 
middle week. Of note...a more progressive wave will move east from 
the plains and to the middle Mississippi Valley by late Tuesday with 
some localized height rises for eastern Kentucky. The model spread 
is a bit larger with this key feature as the NAM lags behind the 
European model (ecmwf) and GFS in bringing the energy with this wave into Kentucky 
later Tuesday night. Have favored the hrrr and nam12 early on in 
the forecast given their higher resolution...before going with 
more of a blend later as uncertainty with the details increase. 


Sensible weather will feature ongoing storms to the north...out 
ahead of the approaching cold front...likely fading as they close 
in on the Ohio River. This will probably send a boundary or two 
into northeastern Kentucky later this morning and it could become 
a focus for convective development for our area through the 
afternoon. This will take place in an environment increasingly 
supportive of strong convection given afternoon convective available potential energy forecast to 
be near 3k j/kg...some middle level drying...and steep lapse rates. 
The winds aloft will be more favorable for organized 
development...too...but the shear is not that impressive. Combined 
with the approach of the main front...though this should be enough 
for at least scattered strong thunderstorms to develop with strong 
to severe ones possible over the northern portion of the County Warning Area late 
in the day. With a relatively low wet bulb zero level and dcapes 
approaching 1500 j/kg large hail and damaging wind gusts will be 
the main threat. Storm Prediction Center has placed a large chunk of the northern 
parts of our area in a slight risk for this concern. Will 
highlight this in the weather story...via a web headline...and in the 
severe weather potential statement. The threat of showers and storms will then continue through 
the night as the front settles south across east Kentucky. The 
clouds and boundary should be enough to keep temperatures warmer 
and more uniform Monday night. Storm chances will continue on 
Tuesday with the front over the area and the approach of the middle 
level wave from the west. 


Again started with the shortblend model for the T/TD/wind grids 
through the day followed by the superblend for tonight and 
Tuesday. Did make some adjustments to temperatures this morning 
and...to a lesser extent...tonight with respect to ridge and 
valley differences. As for probability of precipitation...went a bit higher than guidance 
through the period given the front hanging over the area...despite 
it being rather moisture starved. 


Long term...(tuesday night through sunday) 
issued at 358 am EDT Monday Aug 3 2015 


The upper level pattern continues to feature a western Continental U.S. Ridge 
and a trough over the east with an active jet stream. This brings 
active weather to the region with a series off shortwaves riding 
over the western ridge and into the Ohio Valley. Despite subtle shifts 
in the western ridge with an active jet stream into the West 
Coast...the GFS and Euro seem to agree on the longwave pattern. 
Though besides the Wednesday and Thursday features...timing will 
still pose quite a problem. 


Details closer to the surface will feature a lingering surface 
boundary being quasi/stationary draped across Kentucky and the lower Ohio 
Valley as several shortwaves track east southeast from the Front 
Range of The Rockies through the plains and into the Ohio Valley. 
Heading further into the period...a good deal of upper level support 
in the form of a strong jet streak enters the West Coast over 
central California and through The Rockies weakening the ridge a bit. This 
pushes a even better well defined wave through the plains and into 
the Ohio Valley by Wednesday night. Models have been hinting at this 
feature for quite a few runs that seem to bring a well defined 
system through Kentucky Wednesday night through Thursday night. The super 
blend agrees with this reasoning as well...advertising well above 
likely probability of precipitation through the Wednesday and Thursday night period. This 
period will prove to be the most interesting and active portion of 
the extended. 


As mentioned earlier...the GFS and Euro diverge in solutions 
heading into the weekend with the upper level pattern flattening in 
the GFS but remaining a bit more amplified in the Euro. Thus...a 
stalled boundary over the Tennessee Valley and along the Appalachians and a 
continued active but subtle upper level pattern will keep shower and 
thunderstorm chances through the last few days of the extended but 
lacking confidence...would be more inclined to stay with and just 
below the solution of the super blend. 


&& 


Aviation...(for the 06z tafs through 06z Monday night) 
issued at 230 am EDT Monday Aug 3 2015 


A broad area of high pressure will remain in control of the 
weather across east Kentucky through the rest of the night. This 
will result in mostly clear skies and good radiational cooling 
likely encouraging the development of fog in the river valleys. 
The fog will become locally dense towards dawn. Accordingly... 
brought some IFR or lower visible/ceiling into the sme and sjs sites with 
MVFR visible possible at sym...similar to last night. All the fog 
will lift shortly after 12z with VFR conditions through the rest 
of the taf period for most sites. However...a cold front and 
potential outflow boundaries will spread south into northeast 
Kentucky later this afternoon and evening with a possibility of 
strong thunderstorms...mainly north of Interstate 64. For 
this...have left mention of thunderstorms in the vicinity in the sym taf after 21z. As for 
winds...expect them to remain light and variable through most of 
the taf period at all the taf sites...however later this 
afternoon we could see some gusts of 10 to 15 kts out of the west-southwest 
ahead of the front in the as it drops toward the far north.
