NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Louisville Kentucky 
703 PM EDT Wed Aug 20 2014 


..forecast update... 
Issued at 700 PM EDT Wed Aug 20 2014 


Strong to severe storms have pushed across southern Indiana and 
central Kentucky, with just a few cells now lingering along the 
Kentucky/Tennessee border. The watch box has been cleared except for just a few 
counties along the Tennessee line, and that should be cleared in 
another hour or so as the storms exit. 


Subsident regime in the wake of these storms will keep 
US dry through the next few hours. Next wave upstream in the northwest flow 
is still poised to trigger another round of isolated/scattered 
T-storms after midnight. 


Issued at 430 PM EDT Wed Aug 20 2014 


Complex over southern Indiana along with another over central Tennessee 
both are taking advantage of an unstable atmosphere across the 
region to force scattered thunderstorms to develop. Given the 
instability from Storm Prediction Center mesoanalysis, 4000 j/kg, as well as potential 
for wet microbursts across parts of our region, went with Severe 
Thunderstorm Watch box south of I-64 and roughly along and east of 
I-65. 


Short term (now through Thursday night)... 
issued at 300 PM EDT Wed Aug 20 2014 


Temperatures in the mid 80s to around 90 with dewpoints in the 
low-mid 70s is making for an uncomfortable afternoon, with a few 
storms starting to pop up. Deck of high clouds streaming in from the 
northwest has helped to hold off significant development across most 
of our region to this point. Have a thunderstorm complex developing 
in the unstable airmass over north central TN, and this complex may 
force some new storms to develop along an outflow boundary in 
southern Kentucky. A few storms also are forming along the corridor from 
Hancock County to Casey County in KY, with even more storms east of 
the complex over south central in. 


Best instability and moisture still resides over southern KY, so 
will keep most focus for severe weather down there the next few 
hours, with a secondary focus over our southeastern counties. For 
this evening, should continue to see scattered development away from 
these focus areas, with the northeast forecast area having the best 
chance to continue with storms after midnight. This region will 
continue to be the focus for development the next few periods, as a 
ridge aloft should help dry out our southwest forecast area Thursday 
and Thursday night. 


That ridge will provide hotter temperatures in our southwest as 
well, with highs Thursday likely reaching the mid 90s. Heat indices 
could top out around 100. Given potential for some cloud cover have 
not gone into the next category, 100-105, for heat indices there. 
Think we can hold off on our more prolonged period of near heat 
advisory criteria until Friday, read on in the discussion below. 


Long term (friday through wednesday)... 
issued at 306 PM EDT Wed Aug 20 2014 


Friday - Monday... 


..heat, humidity, and generally unsettled weather this weekend... 


An upper ridge will be in place through this weekend and into next 
week, keeping hot and muggy conditions in place. Upper ridge looks 
"dirty" with very little in the way of a subsidence inversion 
normally seen with this type of environment. Therefore, can't do 
away with storm chances each afternoon and evening. Models are 
generally all over the place with expected precipitation fields each 
day, despite the fairly good agreement in the overall pattern. 
Therefore will just keep isolated to scattered thunderstorms in the 
forecast pretty much every day and evening. 


As far as temperatures go, highs look to top out in the low and mid 
90s each day Friday through Monday as a core of 850 mb temps between 
20 to 23c settle over the area. Some spots could touch the upper 90s 
in our western Kentucky counties. Heat indices will be a bit of a 
concern during this time period as the hot temperatures will combine 
with dew points in the low and even mid 70s. Highest heat indices 
each afternoon could top out in the 100-105 range, so forecast needs 
to be monitored for a potential heat advisory due to a prolonged 
period of days where heat indices approach criteria (105f). This 
advisory would come with a later forecast issuance. One factor that 
could limit temperatures and associated heat indices could be the 
afternoon/evening convection. 


Tuesday - Wednesday... 


Confidence lowers for the Tuesday/Wednesday time frame as some 
degree of troughing over the western Continental U.S. Tries push the upper 
ridge axis east. Should this scenario play out, it would bring 
better chances for storms to our western cwa, along with 
temperatures not as hot. As a result, will go with highs around 90.

Aviation (18z taf update)... 
issued at 125 PM EDT Wed Aug 20 2014 


Confidence in convective forecast this period is low, as cirrus 
shield from storms to our northwest quickly moves into the region. 
Have some cumulus developing over the central forecast area this 
hour, and Storm Prediction Center mesoanalysis indicates plenty of instability across 
the region. However, the cirrus canopy should provide some 
subsidence to inhibit convection. There is still a possibility that 
the storms to our northwest can remain organized enough to bring 
those storms to the terminals later this afternoon. Thus have gone 
with vicinity storms over a larger period of time and will update as 
the afternoon progresses. May even get into another round of precip 
later tonight, as additional disturbances move in from the 
northwest, but a lot will depend on what happens this afternoon. Fog 
forecast for Thursday morning will depend on that as well. Given 
very high dewpoints across bwg this hour, have enough confidence to 
go with a period of MVFR conditions, as in current guidance.
