FOR 12Z AVIATION DISCUSSION.  
 

 
   
DISCUSSION
 
 
UPPER HIGH TO REMAIN IN CONTROL ACROSS THE DEEP SOUTH THROUGH THE  
NEAR TERM PERIOD. HIGH PRESSURE IS ALSO LOCATED AT THE SFC AND  
STACKS WELL WITH THE AFOREMENTIONED UPPER FEATURE. SUBSIDENCE EXTENDS  
A REASONABLE DISTANCE NORTHWARD AND SOME NORTHERN EXTENDED RIDGE  
AXIS DEVELOPMENT HAS BEEN NOTED. 850 MB TEMPS WILL CONTINUE TO RUN  
AROUND 18C AND SO LOWER 90S WILL CONTINUE FOR HIGHS. RECORD HIGHS  
INCLUDE 93 FOR BOTH TODAY AND SATURDAY FOR BNA. OFFICIALLY, I AM  
EXPECTING 92 FOR BOTH DAYS SO IT WILL BE CLOSE. YESTERDAY, THE  
RECORD OF 91 WAS TIED. OTHERWISE, NOT LOOKING FOR MUCH IN THE WAY OF  
FOG THE NEXT 2 OVERNIGHTS. 12Z DEWPOINT DEPRESSIONS LOOK A TOUCH TOO  
HIGH.  
 
IN THE EXT FCST, UPPER HIGH ELONGATES WEST TO EAST AND SINKS FURTHER  
SOUTH ACROSS THE GULF. WESTERLIES WILL INCREASE ACROSS TENNESSEE,  
BUT PRIOR TO A WEAK FROPA ON THURSDAY, HEIGHTS WILL STILL REMAIN  
ELEVATED. LOOK FOR LOWER 90S TO PERSIST INTO THE MIDDLE OF THE WEEK.  
BY THURSDAY AND FRIDAY HOWEVER, TEMPS MAY BACK DOWN A FEW DEGREES  
WITH HIGHS HOLDING IN THE 80S ON THURSDAY PERHAPS. CONVECTION  
CHANCES WILL BE INCLUDED ALONG AND JUST AHEAD OF THE FROPA BUT POPS  
WILL BE LOW.  
 

 
   
AVIATION
 
 
12Z TAF DISCUSSION.  
 
WITH HIGH PRESSURE RULING THE REGION, VFR CONDITIONS ARE EXPECTED  
WITH LIGHT SOUTHERLY TO SOUTHWESTERLY WINDS THROUGHOUT THE CYCLE.  
 
A COUPLE OF THE HIGHER-RES MODELS ARE SHOWING A COUPLE OF POP-UP  
THUNDERSTORMS THIS AFTERNOON, BUT WITH THE EXTREMELY ISOLATED  
NATURE OF ANY POTENTIAL CONVECTION, CAN'T BE CERTAIN ENOUGH FOR  
ANY PREVAILING LINES.  
 

 
   
OHX WATCHES/WARNINGS/ADVISORIES
 
 
NONE.
