Area forecast discussion 
National Weather Service Louisville Kentucky 
300 am EDT Sat Aug 30 2008 


Short term (today and tonight)... 


Weak convergence along a lingering surface boundary to combine with 
some residual low level moisture and afternoon sunshine to bring the 
slight chance for isolated showers and thunderstorms this afternoon 
over the extreme northeastern counties. Otherwise...high pressure 
will build in from the northwest with slowly drying air mass this 
afternoon and tonight. 


Temperatures will again be in the upper 80s to lower 90s...though 
most locations should see a few degrees less than what was 
experienced Friday. Tonight...will see mostly clear skies and low 
temperatures mainly in the middle to upper 60s. 


Long term (sunday through friday)... 


Most of the extended will be dominated by ridging over the 
region...leading to dry weather and highs up around 90 into the low 
90s through about Wednesday. 


Sunday through Wednesday... 


Strong ridging over the Midwest still looks on track for the 
beginning of next week. High temperatures will be some 5 to 8 degrees 
above normal for this time of year. Have only made slight 
temperature/cloud adjustments from previous forecast. Winds will stay light 
out of the east until Wednesday when the surface high pressure drifts far 
enough east to turn winds to the S over the forecast area. 


The rest of the forecast remains unchanged. The previous discussion 
is as follows: 


Thursday and Friday... 


The best chance of precipitation looks to be late next week when moisture 
increases due to tropical systems Gustav and/or Hannah pushing into 
the Gulf and pooling moisture northward into the middle-MS and Ohio 
valleys. Only inserted probability of precipitation for Friday at this point given 
timing/track issues with the tropical systems. Lowered high temperatures 
late next week...about 5 degrees below HPC guidance...and closer to 
ensembles/12z mex MOS.

Aviation (06z tafs)... 


Fog main concern for the taf period...with MVFR visible likely at Lex 
and sdf through 14z Saturday...and possible at bwg. Some periods of 
IFR will be likely between 10-13z at Lex. 


After 14z...high pressure will bring VFR conditions to the terminal 
locations through the end of the taf period.

Lmk watches/warnings/advisories...
