 Special Statement  Statement as of 8:50 PM EDT on October 19, 2014


... Patchy frost possible in the sheltered valleys tonight...

Mostly clear skies... light winds... and a chilly air mass will lead to
the potential for patchy frost in the most sheltered valleys of
eastern Kentucky late tonight and into early Monday morning. Patchy
fog is also expected for valley locations that do not see frost...
particularly places that are near rivers and lakes.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Jackson Kentucky 
646 am EDT Monday Oct 20 2014 


Update... 
issued at 635 am EDT Monday Oct 20 2014 


Forecast seems to be on track so far this morning for the most part. 
The line of rain showers is showing some signs of strengthening and 
better organization as we continue to track it/S movement across the 
Ohio River into Kentucky. However...latest observations are still only 
indicating light rain with very little visibility restriction. Main 
update was to tweak temperatures in the near term. Loading in the 
observational data to the ongoing temperature forecast proved to drop 
currently forecasted temperatures down several degrees in some 
locations. Blended this out for several hours...with temperatures 
expected to start heating from this point forward as the sun begins 
to rise.

Short term...(today through tuesday) 
issued at 359 am EDT Monday Oct 20 2014 


The Rex block pattern continues over the Continental U.S. This morning...with 
much of the eastern Continental U.S. Being influenced by a strong troughing 
pattern. This trough will continue to be our main weather driver for 
the short term today through Tuesday. During the day today...a 
shortwave embedded in the longwave pattern will continue to 
strengthen as it moves from the upper Great Lakes this morning to 
the lower Great Lakes by late this afternoon and evening. By 
tomorrow night it will strengthen into a closed low...then dive 
southward during the day Tuesday...reaching the Virginia/S by Tuesday 
evening. Here it will stall out before slowly moving up the New 
England sea board during the extended period. 


For today...as the shortwave strengthens...it will drive a surface 
low pressure system from the upper Great Lakes to the lower Great 
Lakes. From this surface system will extend a cold front. As the low 
moves...the cold front will sweep from northwest to the southeast...and eventually 
traverse eastern Kentucky late tonight and into Tuesday morning. As 
such...upper level clouds have already protruded into the region 
this morning in advance of this system. A weak scattered line of 
rain showers is not far behind...currently moving across much of 
Northern Ohio...in...and western Kentucky. So far these showers are showing 
up on the radar as very light...with little impacts expected. 
Unfortunately...latest models are having a hard time coming to a 
conclusion about the precipitation as it reaches eastern Kentucky and continues 
ahead of the front today and tonight. The exact location of where 
the best quantitative precipitation forecast and probability of precipitation will be located continues to differ from model 
to model. There is a slight lack in consistency between offices for 
probability of precipitation over the next 24 hours. Tried to match up as best as possible. 
Regardless...this is a moisture deprived system...so any rain that 
does occur is not expected to cause much in the way of impacts and 
should be moving through the area fairly fast. 


Once the frontal boundary moves through US by tomorrow 
morning...expect the return of a more northerly flow pattern and 
cooler temperatures. Afternoon temperatures will only top off in the upper 
50s to around 60 once more. Although the frontal boundary will have 
exited...the upper level low will be on its transition southward 
towards the Virginia/S...pulling the surface low pressure system with 
it. Strong northerly flow will allow for wrap around moisture to 
continue to flow into eastern Kentucky off the backside of the low. This 
moisture will be very weak...but upslope flow in the far east could 
be enough to produce light showers in this area both tonight and 
through the day tomorrow. Expect little impact from this...with only 
very light accumulations expected. 


Long term...(tuesday night through sunday) 
issued at 501 am EDT Monday Oct 20 2014 


An upper trough axis is forecast to be over the Appalachians at the 
start of the period...in the process of forming a large closed low 
at its base as it slowly shifts eastward. At the surface...a large 
low pressure system is expected to be meandering near the middle 
Atlantic coast. It will put our local area in a region of cold air 
advection and upslope flow...favoring low level instability with 
clouds and possibly showers. As the entire set-up slowly shifts 
eastward...it should take any showers with it by Wednesday. A surface 
ridge will then be our dominant feature into Friday. By Friday 
evening both the GFS and European model (ecmwf) indicate a shortwave trough nearing 
from the northwest. The 00z European model (ecmwf) has some light precipitation with this on 
Friday night...but this was not the case in the previous run...and 
the GFS is still basically dry. Will stick with probability of precipitation below the 20 
percent threshold at this point...keeping the forecast dry. A cool 
air mass and sufficient radiating at night will present a 
possibility of frost for the first few nights...mainly in valleys.

Aviation...(for the 12z tafs through 12z Tuesday morning) 
issued at 646 am EDT Monday Oct 20 2014 


A line of showers is currently moving across the Ohio River into Kentucky 
ahead of an approaching cold front. Expect these showers to be light 
and scattered in nature...affecting much of eastern Kentucky through the 
day and into the overnight. Went ahead and included vcsh at this 
time...given the uncertainty of where and when exactly these showers 
will affect a given taf site. Latest models are still showing ceilings 
likely lowering throughout the afternoon and into the overnight hours 
as well. Expect VFR conditions to generally stay intact until the 
overnight tonight...when some MVFR ceilings are possible. Despite a 
frontal passage...winds should generally remain under 10kts both 
today and tonight...switching from SW during the day today...to more 
wrly late tonight after the frontal passage.
