NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Louisville Kentucky 
1258 am EDT Wed Jul 23 2014 


..updated aviation discussion... 


Short term (now through Wednesday night)... 
issued at 305 PM EDT Tue Jul 22 2014 


Temperatures this afternoon have climbed into the upper 80s to lower 
90s with heat indices in the lower to mid 90s. A few light to 
moderate shower have popped up along a deformation band stretching 
across central Kentucky. A few strikes of lightning may be possible 
with the strongest cells with brief heavy downpours. These showers 
will dissipate this evening with the overnight period being dry. 
Lows tonight will drop only into the lower 70s, with mid 70s in the 
Louisville Metro. 


Models continue to indicate the cold front will approach the 
northern portions of the forecast area by late morning to early 
afternoon. Showers and storms will develop ahead of this front 
tomorrow morning and spread across the region through the day. These 
storms look to be scattered in nature. Chances for severe weather 
continue to look small as wind profiles will be rather light. 
However, with ample instability and plenty of moisture, a few strong 
to marginally severe storms with gusty winds cannot be completely 
ruled out. Heavy rain will be the other potential threat with these 
storms as precipitable water values climb into the 1.8-1.9 inch range. Ponding of 
water may develop with any slow moving or training storms. High 
temperatures will be tricky tomorrow and depend somewhat on how fast 
the precipitation moves in and how much coverage there is. In 
general, have gone with highs in the mid 80s across portions of 
southern Indiana and upper 80s to lower 90s elsewhere. 


Precipitation will be ending tomorrow night with rain chances 
shifting eastward as the front moves through. Cooler air will begin 
to move in behind the front tomorrow night. Lows will be cooler than 
tonight, ranging from the lower to upper 60s from northwest to 
southeast. 


Long term (thursday through tuesday)... 
issued at 305 PM EDT Tue Jul 22 2014 


Showers/T-storms associated with the aforementioned cold front and 
upper level trough should exit the area early thurs morning. 
Cooler, pleasant weather will follow thurs/Fri as Canadian high 
pressure moves south into the area along with an upper level 
trough. High temps will be in the upper 70s and lower 80s thurs/Fri 
under mostly sunny skies. Night time lows will be in the 60s. 


Flow will become more zonal across the Continental U.S. For Sat before another 
upper low dives south into the Midwest for sun/Mon. This will 
result in temps returning closer to normal for Sat...in the upper 
80s to around 90 for highs. Then temps will drop below normal 
(lower 80s) again for the beginning of next week as another upper 
level trough becomes established over the Midwest. 


This pattern will continue to bring multiple chances for 
showers/T-storms to the region Sat-tues. The first may arrive in 
the form of an mesoscale convective system Sat in northwest flow. Continued on and off 
chances for storms will continue ahead of a cold front progged to 
move through some time Monday. These finer details are hard to time 
this far out so look for refined forecast pop timing in later 
issuances. Tuesday looks dry and cool behind the front.

Aviation (06z taf update)... 
issued at 1258 am EDT Wed Jul 23 2014 


Overall, the first several hours of the taf period should be quiet. 
There are a couple of possible problems that could crop up, though. 
One is a chance of some high-end MVFR br/haze towards sunrise. The 
other is a small chance of showers a couple hours either side of 
dawn, especially at Lex and sdf, as a small wave (near stl at 04z) 
comes in. The chances of vsby restrictions and the likelihood of 
significant showers are small enough to leave out of the tafs for 
now. 


An upper wave over Iowa early this morning will push to the 
southeast and reach the Ohio Valley this afternoon. Also, a surface 
cold front will cross the region during the early and mid afternoon 
hours. These features will bring the possibility of scattered 
showers and thunderstorms this afternoon and evening. Nevertheless, 
VFR conditions will prevail. 


Winds from the west-southwest ahead of the front will switch to the northwest 
behind the front and eventually due north by tonight. Speeds will 
mostly be at or below 10 knots.
