AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NASHVILLE TN
1151 PM CDT SUN AUG 30 2015

.AVIATION UPDATE...FOR 06Z TAFS

EARLIER SHOWERS HAVE DISSIPATED AND MUCH OF THE CLOUD COVER
OVERHEAD IS THINNING OUT. ONLY EXCEPTION IS CLOSER TO THE PLATEAU
AND THUS CSV WHERE A WEAK UPPER LOW IS LOCATED. CLOUD COVER AND
ISOLATED SHRA FROM THAT COULD STILL AFFECT CSV THROUGH ROUGHLY
12Z AS THE UPPER LOW PUSHES NORTHWARD INTO KY.

OTHERWISE...PARTIAL CLEARING AND AMPLE LOW LEVEL MOISTURE SHOULD
LEAD TO LIGHT FOG ACROSS MIDDLE TN. LOWEST VSBYS...AT TIMES BELOW
1 SM...SHOULD BE LOCATED AT CKV AND CSV FROM 07-13Z WHERE RAIN
FELL EARLIER TODAY. ONCE THE FOG BURNS OFF MID-MORNING
MONDAY...VFR CONDITIONS ARE EXPECTED THRU 06Z TUESDAY.

.PREV DISCUSSION... /ISSUED 731 PM CDT SUN AUG 30 2015/

2 DISTINCT SHORTWAVE AXES IN PLACE THIS EVENING. THE FIRST IS
LOCATED FROM THE ARKLATEX AND EXTENDS NE. THE SECOND IS OVER NRN
GA AND EXTENDS NW. MOISTURE POOL IS GREATEST ON THE EAST SIDE OF
BOTH AXES. THUS...WE HAVE ACTIVITY ONGOING ACROSS WESTERN TN.
HOWEVER...UD FIELDS AND MOISTURE DEPTH LEVELS SHOULD DECREASE
BETWEEN NOW AND 12Z.

HRRR AND MODEL DATA BOTH SUGGEST THAT THE ACTIVITY SHOULD DIE OFF
BEFORE 06Z. WILL GO AHEAD AND REMOVE THE POST 06Z POPS.

AS FOR FOG POTENTIAL...DEWPOINT DEPRESSIONS ARE RATHER LOW ACROSS
THE NORTHWEST THIRD...WHERE FCST FOG INCLUSION IS ABSENT. MODELS
DEPICT LOW T-TD SPREADS BY 12Z. FURTHERMORE...NUMERICAL GUIDANCE
SUPPORTS FOG DEVELOPMENT OVER OUR WESTERN AREAS. WILL ADJUST THE
06Z-12Z GRIDS AND INCLUDE PATCHY FOG ACROSS ALL OF THE MID STATE
NOW.

OTHER THAN A SLIGHT UPWARD CLOUD TWEAK...REMAINDER OF FCST IS ON
TRACK. UPDATE OUT SHORTLY.

.OHX WATCHES/WARNINGS/ADVISORIES...
NONE.
