Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HUNTSVILLE AL
656 PM CDT SAT JUL 30 2011

.UPDATE...
UPDATE FOR 31/00Z AVIATION FORECAST.

&&

.AVIATION...
WSR-88D DATA INDICATES THAT SHRA/TSRA THREAT WILL PERSIST FOR A
COUPLE OF HOURS AFTER 31/00Z AT BOTH HSV/MSL...AND WILL INCLUDE
VCTS/CB AS PREVAILING CONDITION. CONVECTIVE ACTIVITY SHOULD DIMINISH
BEYOND THIS POINT...WITH FOCUS SHIFTING TO POTENTIAL FOG/STRATUS
EVENT EARLY SUNDAY MORNING. FORECAST SOUNDINGS APPEAR A BIT MORE
FAVORABLE FOR STRATUS THAN WIDESPREAD FOG...AND WILL INDICATE VSBY
DETERIORATING BEGINNING AROUND 31/05Z...WITH PREVAILING MVFR CIG/VSBY
IN STRATUS AND LIGHT BR BTWN 31/07-13Z. WITH LOW-LEVEL WINDS ALREADY
EXPECTED TO BE NNW AROUND DAWN AND LITTLE IN THE WAY OF LOW-LEVEL
CONVERGENCE OR UPPER-LEVEL FORCING...AM VERY UNCERTAIN ABOUT CHANCES
FOR SHRA/TSRA TOMORROW...AT LEAST THRU THE END OF THIS FORECAST
PERIOD. WILL NOT MENTION VCTS/CB AT THIS POINT...WITH STORM CHANCES
POSSIBLY INCREASING A BIT TOMORROW EVENING AS ACTIVITY SPREADS IN
FROM THE NORTH. LGT/VRBL WINDS OVERNIGHT WILL INCREASE TO 5-10 KNOTS
FROM THE NNW/N AFTER SUNRISE.

.PREV DISCUSSION... /ISSUED 122 PM CDT SAT JUL 30 2011/

FINALLY SOME ACTIVITY TO SPEAK OF ON THE RADAR THIS AFTN. HIGH PWAT
VALUES (IN EXCESS OF 2 INCHES) AND MODEST CAPE VALUES HAVE LED TO
SCATTERED/NUMEROUS SHRA/TSRA DEVELOPMENT ACROSS THE REGION. ACTIVITY
MAY ALSO BE AIDED BY A WEAK UPPER LEVEL IMPULSE NOTED ON WATER VAPOR
IMAGERY AND DETAILED IN 12Z RUC/WRF ANALYSES. HAVE SEEN FAIRLY
EFFICIENT RAIN PRODUCERS WITH WARM CORE/LOW TOP STORMS TODAY...WITH
RAIN RATES EXCEEDING 4-5"/HR AT TIMES. FORTUNATELY ..THERE IS ENOUGH
SE COMPONENT TO THE FLOW TO KEEP THINGS FROM REALLY GETTING OUT OF
HAND.

IN THE SHORT TERM...EXPECT CONVECTION TO LINGER FOR A BIT DUE TO WEAK
UPPER LEVEL SUPPORT. HARD TO REALLY DISCERN ANY SIGNIFICANT SFC
FEATURES TO BE HONEST IN THE VICINITY. WIND AND THERMAL FIELDS ARE
VERY OUTFLOW DOMINATED AT THIS POINT. THERE IS A MORE NOTABLE SFC FRONT
WELL TO THE NORTH ACROSS SRN KY AND THE MO BOOTHEEL. THIS FRONT IS
PROGGED TO PUSH SOUTH AND/OR GENERALLY DISSIPATE OVER THE NEXT 24 TO
36 HOURS. FOR TONIGHT...EXPECT GENERALLY CLEARING AS THE AIRMASS
STABILIZES. WOULD EXPECT PATCHY FOG DEVELOPMENT...ESPECIALLY CENTRAL
AND EASTERN AREAS DUE TO TODAY'S RAINFALL AND WILL INCLUDE IN
OVERNIGHT FORECAST.

TOMORROW/SUNDAY MAY ACTUALLY BE THE TRICKIEST DAY OF THE 7 DAY
FORECAST. THE NAM/GFS DIFFER ON THE PLACEMENT OF THE SURFACE AND
UPPER LEVEL FEATURES (ALBEIT SUBTLE FEATURES)...AND THE RESULT IS A
WIDE VARIATION IN BOTH THE TEMPS AND POPS FROM THE MOS GUIDANCE. I AM
NOT SOLD ON THE AFOREMENTIONED FRONT SOLIDLY PUSHING ALL THE WAY
THROUGH AND SUBSTANTIALLY DRIER AND MORE SUBSIDENT FLOW MAKING ITS
WAY IN BY MIDDAY SUNDAY. THUS...WILL TREND TOWARD THE SLIGHTLY WETTER
GFS SOLUTION. WE MAY WANT TO ENJOY SUNDAY THOUGH AS THE FURNACE
REALLY STARTS TO GET CRANKED BACK UP AS WE HEAD INTO THE UPCOMING
WORK WEEK.

THE BROAD SURFACE RIDGE CENTERED ACROSS THE NATION'S MIDSECTION WILL
BUILD EASTWARD AND AMPLIFY WITH TIME IN THE 3-6 DAY PERIOD. THIS
WILL BRING ANOTHER ROUND OF OPPRESSIVE HEAT AND DRY WEATHER TO THE
TENNESSEE VALLEY REGION. ENSEMBLE OF EXTENDED GUIDANCE SUGGESTS
MAXIMUM TEMPERATURES RUNNING IN THE UPPER 90S IN MOST AREAS IN THE
TUE THROUGH FRI TIME PERIOD WITH HEAT INDICES ONCE AGAIN REACHING
ADVISORY CRITERIA FOR THE MAJORITY OF THE REGION. WE COULD SEE
EXCESSIVE HEAT WARNING CRITERIA IN A FEW AREAS AS WELL. WITH THE
UPPER LEVEL RIDGE IN PLACE...SUBSIDENCE SHOULD PREVENT APPRECIABLE
CONVECTION UNTIL LATER IN THE WORK WEEK AND EVEN THEN AREAL COVERAGE
LOOKS PALTRY AT BEST. PREVIOUS FORECAST HAD THIS HANDLED FAIRLY WELL
AND HAVE NOT MADE ANY MAJOR CHANGES TO THE EXTENDED PERIOD WITH
DURING THIS FORECAST CYCLE.
