.DISCUSSION...
/ISSUED 917 PM CDT MON JUL 6 2015/

ISOLATED SHOWERS WERE OBSERVED EARLIER IN THE EVENING...HOWEVER ALL
ACTIVITY HAS DISSIPATED ACROSS THE FORECAST AREA. LATEST WATER VAPOR
IMAGERY SHOWS AN UPPER TROUGH MOVING NORTHEAST ACROSS THE
APPALACHIANS...WITH DRY AIR FILTERING ON THE WESTERN PERIPHERY OF
THE TROUGH. MEANWHILE...SEVERAL WEAK UPPER LEVEL SHORTWAVES WERE
DRIFTING EASTWARD ACROSS THE PLAINS AND MISSISSIPPI VALLEY. ISOLATED
TO SCATTERED THUNDERSTORMS HAVE DEVELOPED ACROSS EASTERN ARKANSAS IN
RESPONSE TO THESE DISTURBANCES...AND CLOUD COVER WAS SLOWLY MOVING
SOUTHEASTWARD INTO THE WESTERN PORTION OF THE FORECAST AREA.

FOR THE REMAINDER OF THE EVENING AND OVERNIGHT PERIOD...EXPECT CLOUD
COVER TO CONTINUE TO MOVE IN...LIMITING THE COOLING OVERNIGHT.
THEREFORE...LOWS WERE RAISED BY A FEW DEGREES ACROSS THE AREA.
ADDITIONALLY...THE DRY AIR ALOFT SHOULD REMAIN IN PLACE ACROSS THE
EAST...AND HAVE TRIMMED THE POPS BACK ACROSS THESE AREAS. WHILE NOT
WIDESPREAD...THE NORTHWESTERN PORTION OF THE FORECAST AREA MAY SEE AN
ISOLATED THUNDERSTORMS AS THE UPPER LEVEL DISTURBANCE MOVES CLOSER TO
THE AREA.

.AVIATION...
FOR 06Z TAFS...

VFR CONDITIONS WILL PREVAIL THROUGH MUCH OF THE FORECAST PERIOD. THE
EXCEPTION WILL BE BETWEEN 10Z AND 12Z...WHEN MVFR MIST IS EXPECTED.
THIS SHOULD LIFT QUICKLY AFTER SUNRISE...GIVING WAY TO VFR CONDITIONS
THROUGH THE REMAINDER OF THE FORECAST PERIOD. WINDS WILL REMAIN FROM
THE SOUTHWEST BETWEEN 5 AND 10 KTS. THERE MAY BE AN ISOLATED
THUNDERSTORM...ESPECIALLY TOMORROW AFTERNOON...HOWEVER COVERAGE IS
TOO LOW TO INCLUDE IN THE TAFS AT THIS TIME.
