Area forecast discussion...updated 
National Weather Service Jackson Kentucky 
1050 am EDT Thursday Aug 21 2014 


Update... 
issued at 1050 am EDT Thursday Aug 21 2014 


14z surface analysis show general low pressure north of the Ohio River 
with higher pressure found to the south. A stationary boundary exists 
through the northern portions of the Ohio Valley and western parts of 
this front...connected back to deeper low pressure over the northern 
plains...has been a genesis region for recent mesoscale convective system activity. This 
activity is also supported by a stream of middle level energy riding 
along the northern fringe of a developing ridge to the southwest of 
Kentucky. This would tend to support convection working southeast 
from the upper Midwest to the central Appalachians passing by just to 
our northeast. However...instability building with the recent 
arrival of Summer time heat and humidity across Kentucky will be 
enough to keep a threat of the storms and their outflow boundaries 
sneaking into northeast portions of the County Warning Area and perhaps further to 
the southwest in the afternoon. The current radar has a healthy 
cluster of storms crossing from Indiana into Ohio with a growing 
southern extent tracking through northern Kentucky. Expect this to 
brush into northern parts of the forecast area through the next 
several hours. The hrrr keeps this first wave just north of the 
County Warning Area...while the 12z nam12 dips the convection deeper into east 
Kentucky. For this update have split the difference between these two 
scenarios and peaked probability of precipitation in the northeast through the afternoon with 
some small to moderate probability of precipitation even down into the Cumberland Valley by 
evening. High precipitable waters  and the rains of the past several days will mean a 
threat of flash flooding for places that see repeated storms... 
particularly through the middle section of the County Warning Area. Storm Prediction Center has placed 
eastern parts of the area...along the previously discussed storm 
track...in a slight risk for severe weather...mainly damaging winds 
and large hail. This appears reasonable given the high cape...low 
lifted indices...and lack of a middle level cap. Accordingly this concern will 
continue to be highlighted in the severe weather potential statement along with a mention of the 
heat and humidity...temperatures near 90 and dewpoints in the 70s...through 
the weekend. Have also fine tuned the T and dew point grids per the latest 
observation...trends...and consshort guidance. These updates have been sent 
to the ndfd and web servers with new severe weather potential statement and zones on their way. 


Update issued at 757 am EDT Thursday Aug 21 2014 


The forecast remains on track this morning. Freshened up the hourly 
temperatures...dew points...and sky cover to account for the latest 
trends in the observations. 


&& 


Short term...(today through friday) 
issued at 357 am EDT Thursday Aug 21 2014 


The latest surface map features high pressure across the Gulf Coast 
states...with low pressure across the plains states. A stationary 
boundary extends east from the plains into the Great Lakes/Ohio 
Valley region. Aloft...an upper level low continues to spin across 
the northern Great Lakes...with an upper level ridge centered near 
the northern Gulf of Mexico...and more troughing featured across 
the northern rockies. Several complexes of thunderstorms have been 
generating and then riding southeast on the periphery of the upper 
level ridge over the past few days. 


Currently...eastern Kentucky remains quiet as only a weakening 
smaller complex of thunderstorms is slowly moving through southeast 
Illinois and southwest Indiana. The next more organized complex is 
currently moving through Minnesota. 


The model guidance has been all over the place with the timing of the 
more organized convection as of late. As such...have used a general 
blend of the guidance and the inherited forecast. As the upper level 
ridge slowly builds into the region through Friday...it will 
generally nudge the mesoscale convective system track further northeast...however since there 
will be plenty of fuel for the storms and a weak synoptic pattern in 
place...can not rule out outflow influence further southwest. Some 
storms could approach severe limits...and isolated flash flooding 
will also be a possibility...especially where storms can move 
parallel to any established outflow boundaries. Will highlight these 
threats in the severe weather potential statement. Probability of precipitation will generally peak in the afternoon hours 
today and Friday...with lesser chances during the overnight hours. 


Highs today will average in the 85 to 90 degree range...with around 
90 degrees expected for most locations on Friday. 


Long term...(friday night through wednesday) 
issued at 357 am EDT Thursday Aug 21 2014 


The extended portion of the forecast begins on Friday night with a 
well developed middle level ridge centered over the middle west and 
longwave trough entering the northwest with an exiting trough over 
the northeast. The middle level ridge axis eventually shifts east over 
the Ohio Valley by Monday as it weakens a bit with the approaching 
trough over the northern plains and the trough over the northeast 
exiting into the Atlantic. This pattern basically keeps the ridge 
over eastern Kentucky through the rest of the extended. 


With this pattern in place through Sunday...eastern Kentucky remains 
in northwest flow with still a few mesoscale convective system/S likely poised to track 
southeast into the area for this weekend. While models inherently 
will have trouble tracking them...the first one should be moving 
through Friday night with the next one possibly Saturday night. By 
Sunday...the ridge axis really begins to set in and additional 
strong convection may be less likely and may be more tied to diurnal 
processes with a stationary boundary along the eastern portion of the 
County Warning Area. By Monday and through Wednesday...the middle level ridge axis 
moves over the area which should effectively cut off convection...at 
least deep convection. Some afternoon showers and possibly a storm or 
two may develop under the ridge. The solution of the all model blend 
would suggest some uncertainty there with the best chance of precipitation 
Friday night through Sunday. This is in good agreement with the GFS 
and Euro as well. Overall the broad brush of probability of precipitation through the first 3 
days of the extended seems needed due to the nature of the models 
having trouble depicting the complexes moving through but did go with 
some diurnal characteristics. 


By the end of the extended...the models seem to hint at the ridge 
moving farther east as a strong shortwave and associated cold front 
seems poised to move through the MS River Valley and into the Ohio 
Valley. In addition...the warm and muggy weather still looks to be 
on tap through the weekend with highs around 90 through Monday and 
dew points around 70. The end of the extended does show some relief 
from the warm and humid weather with the approach of the 
aforementioned cold front.

Aviation...(for the 12z tafs through 12z Friday morning) 
issued at 757 am EDT Thursday Aug 21 2014 


IFR or worse fog/stratus will dissipate by around 13z. Scattered to 
numerous convection will likely threaten once again from 16z through 
early this evening. Timing this activity continues to be very 
challenging so will keep thunderstorms in the vicinity wording only at this time. Some MVFR 
or worse fog will likely be seen once again after 04z tonight. Winds 
of around 5 kts or less will remain out of the southwest through the 
period as well.
