.DISCUSSION...
/ISSUED 947 PM CDT FRI JUL 19 2013/
ALL OF THE CONVECTION IN THE HUNTSVILLE CWFA HAD DIED OUT OR MOVED
OUT UNTIL ABOUT 830 PM, WHEN ONE ROGUE CELL DEVELOPED NEAR HAMPTON
COVE...AND HAS JUST KEPT ON GOING. AS A RESULT, A SWATH OF EASTERN
MADISON COUNTY IS GETTING A GOOD SHOT OF RAIN THIS EVENING. A 00Z
SOUNDING RELEASED BY UAHUNTSVILLE INDICATED STILL SOME RESIDUAL
INSTABILITY DESPITE INCREASING DEBRIS CLOUD COVER, AND THE MADISON
COUNTY STORM--AND ONE ROGUE STORM IN NORTHEASTERN JACKSON COUNTY--ARE
TAPPING INTO THAT. SURFACE AND UPPER-AIR CHARTS ARE RATHER
UNREMARKABLE, INDICATING LITTLE SYNOPTIC-SCALE FORCING THAT COULD BE
AFFECTING THE AREA.

ONCE THESE ISOLATED STORMS DIE DOWN, THE NIGHT SHOULD BE QUIET--BUT
RATHER WARM AND MUGGY. SEVERAL SITES ARE STILL IN THE LOW-MID 80S AS
OF 02Z, AND EVEN TYPICALLY-COOL SPOTS SUCH AS FORT PAYNE ARE STILL
SITTING AT 77, LIKELY DUE TO THE DEBRIS CLOUDS. SO WILL NUDGE LOW
TEMPERATURES UP JUST SLIGHTLY, STILL KEEPING WITH A CLIMO-FRIENDLY
LOW-MID 70S RANGE ACROSS THE REGION.

FOR 06Z TAFS...NO CHANGES FROM PREVIOUS AVIATION FORECAST REASONING.
VFR CONDS ARE EXPECTED TO CONTINUE AT BOTH MSL/HSV THRU THE NEXT 24
HOURS...WITH A PERSISTENT/LIGHT SSW WIND AND LAYERS OF SCT HIGH-
BASED CU/AC. INCREASING ATMOSPHERIC MOISTURE SUGGESTS THAT THE
COVERAGE OF SHRA/TSRA MAY BE A BIT HIGHER TOMORROW...AND HAVE
INCLUDED VCTS/CB FOR BOTH TERMINALS AFTER 14Z. SFC FLOW TOMORROW WILL
REMAIN FROM THE SSW...BUT INCREASE TO 8-10 KNOTS BEGINNING AROUND
