NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Louisville Kentucky 
309 PM EDT sun Jul 5 2015 


Short term (now through Monday night)... 
issued at 257 PM EDT sun Jul 5 2015 


Water vapor imagery this afternoon shows a well defined circulation 
in the upper level flow over eastern Kentucky. At the surface low 
pressure is centered near the Kentucky/Virginia border. The majority of the 
showers this afternoon will be across east central Kentucky where 
light to moderate rains continue. There could be a few stronger 
showers around the Lake Cumberland area. However, for the most part 
these should only produce brief heavy rainfall and are not expected 
to cause any additional flooding issues. Therefore have decided to 
cancel the Flash Flood Watch this afternoon. Short term models also 
have isolated to scattered showers developing across southwestern 
portions of south central Kentucky this afternoon. These should wane by 
late afternoon. 


All of the rain should move out of the area by early evening. The 
overnight hours are expected to be dry with light to calm winds and 
partly to mostly cloudy skies. With plenty of low level moisture, 
some patchy fog may develop across the region, so have added that in 
to the forecast. 


Southwesterly flow will set up tomorrow ahead of a cold front which 
will begin to approach the region tomorrow night. There will be 
little in the way of large scale forcing tomorrow. However, 
relatively unstable soundings and a very weak upper level 
disturbance moving through the flow could spark isolated showers 
and/or thunderstorms. Rain chances will be on the increase late 
Monday night as the cold front nears from the northwest. 


Temperatures Monday are expected to be on the warm side with highs 
in the mid to upper 80s. Lows tonight and tomorrow night will be in 
the upper 60s to lower 70s. 


Long term (tuesday through sunday)... 
issued at 300 PM EDT sun Jul 5 2015 


Tuesday still looks to be the wettest day in the long term period as 
a front drops southeast into the Ohio Valley. Although the 
strongest mid to upper level flow should remain to our north, there 
may be enough 0-6 km bulk shear to produce some strong storms with 
gusty winds. Storm strength will also depend on available 
instability. While models are showing some, it may be difficult to 
build much if we start the day cloudy with an initial round of 
showers/storms. Will need to watch the evolution/timing of this 
weather system in coming days. 


For mid week, the front looks to stall over our region initially 
with uncertainty still in how quickly a southeast Continental U.S. Ridge will work 
into the Ohio Valley and just how strong it will get. Most mid 
range models continue to support shortwaves riding along the 
boundary producing multiple rounds of showers/storms tues night/Wed. 
By Wed night/thurs, most models indicate that the boundary will be 
far enough north, to result in lesser pops. Even the recent, wetter 
outlier (the euro) has trended drier on its 12z run. However, the 
door is still open for diurnally based convection peaking during the 
afternoon/evening hours. This pattern looks to potentially hold 
through the weekend with daily pops. If the recent drier 
model consensus holds, at least some dry periods during the 
overnight hours might be added to the forecast beyond mid week. 


Temperatures will generally range through the 80s for highs for 
tues-thurs with lows in the upper 60s/lower 70s. As the ridge 
builds into the Ohio Valley, it will bring a warmer airmass 
resulting in high temps in the mid 80s to lower 90s for Fri-sun with 
lows in the lower 70s.

Aviation (18z taf update)... 
issued at 1244 PM EDT sun Jul 5 2015 


Light rain over Lex will move out over the next few hours as an 
upper level low shifts eastward. Ceilings are expected to rise to 
VFR after the precipitation moves out. Thereafter, VFR conditions 
and light winds will prevail through the evening hours. Some light 
fog will be possible once again tomorrow morning at Lex and bwg. 
This should dissipate by mid morning with winds out of the SW and 
partly cloudy skies for the remainder of Monday.
