Update...for 18z aviation.

Aviation... 


Upper ridging will have a hold on the middle Tennessee weather through 
the next 24 hours. Mostly VFR conditions will prevail...with 
isolated-scattered rain showers/thunderstorms and rain being possible this afternoon...and 
again Thursday afternoon but beyond this 24-hour time period. May 
introduce a vcsh this afternoon at the area terminals since any 
convection should be widely scattered...with the best chance 
occurring between 20z-02z. Will amend should thunderstorms and rain develop near a 
terminal. 


Overnight...IFR (mvfr) visibilities may develop at csv (ckv) towards dawn 
Thursday from light fog but overall conditions will be calm and 
clear overnight. More scattered cumulus around 4-5kft will develop by the end 
of this taf period. Light nearly winds today will shift to light 
southeasterly winds tomorrow.

Update... 
upper trough will pull away today from the Tennessee Valley with 
dirty upper ridge trying to build this way. This will lead to a 
more summery pattern for the next several days. Looking for mostly 
sunny sky today with light northerly flow down into the middle state. 
With temperatures getting into the upper 80s isolated afternoon and very 
early evening convection is expected.
