UPDATE
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.
