.DISCUSSION...
/ISSUED 1050 AM CDT MON AUG 31 2015/

15Z SURFACE ANALYSIS DEPICTS A BROAD AREA OF HIGH PRESSURE ACROSS
MUCH OF THE EASTERN CONUS...WITH TEMPERATURES ACROSS THE LOCAL AREA
IN THE MID TO UPPER 70S. A DEEP PLUME OF MOISTURE CAN BE SEEN
ADVECTING NORTHWARD INTO THE FORECAST AREA...AS OBSERVED ON WATER
VAPOR IMAGERY. GIVEN THIS MOISTURE FETCH...AND TEMPERATURES EXPECTED
TO REACH INTO THE 80S...AN ISOLATED THUNDERSTORM IS POSSIBLE DURING
THE PEAK HEATING HOURS OF THE AFTERNOON. HOWEVER...NOT EXPECTING
ANYTHING WIDESPREAD AND WILL MAINTAIN THE ISOLATED THUNDER IN THE
FORECAST. THE PREVIOUS FORECAST SEEMS TO BE ON TRACK AND ONLY CHANGES
MADE WERE TO UPDATE THE TRENDS IN THE HOURLY TEMPS AND DEWPOINTS.

.AVIATION...
FOR 18Z TAFS... CIGS THAT ARE RUNNING MVFR (015-030AGL) WILL EITHER
LIFT OR SCATTER OUT VERY SOON, SO HAVE GONE WITH VFR BEGINNING AT
18Z. AN ISOLATED SHRA OR TSRA IS PSBL, BUT HAVE NOT INCLUDED IN THE
FORECAST.  WE SHOULD SEE A CLEARING TREND AFTER DAYTIME HEATING
CEASES. EITHER BR OR LOW CIG DEVELOPMENT IS EXPECTED TONIGHT.

RADIATION FOG (4-5SM BR / MVFR) FROM 09-12Z GIVEN EXPECTED
HEATING/DRYING THIS AFTERNOON.
