AREA FORECAST DISCUSSION

708 PM CDT SUN JUL 3 2011

.UPDATE...
UPDATE FOR 04/00Z AVIATION FORECAST.

&&

.AVIATION...
VFR CONDITIONS WILL CONTINUE THRU THE MAJORITY OF THE FORECAST PERIOD
AT BOTH MSL/HSV...ALTHOUGH GENERALLY CLEAR SKIES AND LIGHT/VRBL
WINDS WILL ONCE AGAIN SUPPORT THE DEVELOPMENT OF LIGHT BR NEAR MSL
DURING THE EARLY MORNING HOURS. WILL INCLUDE TEMPO GROUP FOR MVFR
VSBY /5SM BR/ AT MSL FROM 04/08-12Z. THE AREAL COVERAGE OF AFTERNOON
SHRA/TSRA WILL BE HIGHER TOMORROW AS COMPARED TO PREVIOUS DAYS...WITH
THE UPPER-LEVEL RIDGE DIMINISHING AND A WEAK SURFACE TROUGH LIFTING
NORTHWARD OVER THE REGION. HAVE INCLUDED VCTS/CB BEGINNING AT 04/16Z
FOR BOTH TERMINALS...ALTHOUGH TSRA PROBS MAY BE SLIGHTLY HIGHER AT
HSV. ANY STORM THAT IMPACTS A TERMINAL WILL BE CAPABLE OF PRODUCING
GUSTY SURFACE WINDS AND A BRIEF PERIOD OF MVFR CIG/VSBY...WITH
PREVAILING WINDS OUTSIDE OF CONVECTION FROM THE SSW AT 5-10 KNOTS.

70/DD

&&

.PREV DISCUSSION... /ISSUED 346 PM CDT SUN JUL 3 2011/

UNDER THE CONTINUED INFLUENCE OF A MID LEVEL RIDGE...TYPICAL
SUMMERTIME AFTERNOON CONVECTION HAS DEVELOPED AGAIN ALONG A WEAK
CONVERGENCE ZONE SE OF THE AREA. IN ADDITION...CONVECTION HAS BEGUN
TO FIRE ALONG A DEVELOPING FRONTAL BOUNDARY FROM SOUTHERN PA TO SW
MO. CLOSER TO HOME...IT HAS BEEN A HOT BUT NICE AFTERNOON WITH
TEMPERATURES SLOWLY CLIMBING INTO THE MID 90S.

FOR TOMORROW...FOR MUCH OF THE DAY HOT AND DRY WEATHER WILL PREVAIL.
BUT TWO AREAS OF PRECIPITATION WILL ENCROACH UPON THE CWA LATER IN THE
EVENING. THE ZONE OF CONVERGENCE TO OUR SE WILL SPARK A REPEAT OF THE
LATE AFTERNOON CONVECTION BUT WILL SLIDE SLIGHTLY WESTWARD AS HAS
BEEN THE TREND THE PAST COUPLE OF DAYS. THE WEAK FRONT TO OUR NORTH
WILL SLOWLY SAG SOUTH AND REACH THE CWA BTWN 00Z AND 06Z TOMORROW
EVENING. THE NAM PROPOSES A SLIGHTLY FASTER SOLN WHILE THE GFS DELAYS
THE ARRIVAL OF THE FRONT UNTIL LATER ON TUESDAY AND KEEPS A DRIER
COLUMN MONDAY EVENING OVER THE TN VALLEY. WHILE THE ECMWF AGREES WITH
THE NAM...THE GFS HAS HAD A BETTER HANDLE ON DEVELOPMENT TODAY AND
THE LACK OF UPPER LEVEL SUPPORT TO MOVE THE FRONT MAKES THE SLOWER
SOLN PLAUSIBLE. HAVE THEREFORE GONE WITH A COMPROMISE FOR A 30-40
POP. ANY STORMS THAT DO DEVELOP TOMORROW DO HAVE THE POTENTIAL TO
BECOME STRONG TO SEVERE...BUT THINK CHANCES ARE LOW AT THIS POINT.
BUFR SOUNDINGS POINT TO MICROBURST POTENTIAL AROUND THE 00Z
TIMEFRAME WITH 1000-2000 J/KG CAPE VALUES (SOME OUTPUT INDICATES
HIGHER VALUES BUT THINK THAT CONVECTIVE FEEDBACK HAS MODIFIED LOW
LEVEL MOISTURE UNREALISTICLY) AND A CLASSIC INVERTED V TYPE
SOUNDING.

AFTER THE FRONT PUSHES INTO THE AREA ON TUESDAY...IT WILL STALL OUT
IN THE SOUTHEAST AND PROVIDE SURFACE CONVERGENCE TO SPARK REPEATED
AFTERNOON CONVECTION. THIS SUMMERTIME PATTERN WILL CONTINUE UNTIL
ANOTHER FRONTAL BOUNDARY ROUNDS THE RIDGE LATE IN THE WEEK. REPEATED
ROUNDS OF STORMS ASSOCIATED WITH PWAT VALUES FROM 1.5 TO 2+ INCHES
COULD CAUSE HYDROLOGY CONCERNS FOR LATER IN THE WEEK IF THEY
MATERIALIZE. OTHERWISE...HIGH TEMPERATURES WILL PERSIST IN THE 90S
AND HEAT INDEX VALUES WILL CONTINUE TO TOP OUT AROUND 100 DEGREES IN
THE WESTERN CWA.
