AREA FORECAST DISCUSSION...UPDATE
NATIONAL WEATHER SERVICE JACKSON MS
1135 AM CDT WED AUG 10 2005

.DISCUSSION...
EARLY INDICATIONS ARE THAT TODAY MAY BE PRETTY ACTIVE CONVECTIVELY
ACROSS PORTIONS OF THE FORECAST AREA. I THINK THE PREVIOUS
FORECASTER (AND HIS DISCUSSION) HAD A PRETTY GOOD HANDLE ON THE
POTENTIAL FOR TODAY AND THE MAIN ATMOSPHERIC FACTORS THAT WOULD HAVE
A STRONG CONTRIBUTION...THOSE BEING THE RRQ OF A MODEST 250 JET, A
DECENT THETA E MAX STRETCHING FROM NORTHWEST TO SOUTHEAST ACROSS THE
SOUTHWEST 2/3RDS OF THE CWA, AND SUBTLE WIND CONVERGENCE IN THE LOW
LEVELS OF THE ATMOSPHERE ROUGHLY ALIGNED WITH THE THETA E AXIS. THIS
MORNING REVEALED LOTS OF MID LEVEL CLOUDS ALONG THE I 20 CORRIDOR
FROM JUST EAST OF JAN BACK TO EAST TX EMBEDDED WITHIN A WEAK MID
LEVEL SHEAR AXIS. THESE CLOUDS HAVE THINNED A BIT THIS MORNING...BUT
THE RESULTING DIFFERENTIAL HEATING BOUNDARIES ON THE NORTH SIDE ARE
REACTING WITH WEAK LOW LEVEL NORTHERLY FLOW TO TRIGGER ISOLATED
CONVECTION ALREADY. ACTIVITY WILL EVENTUALLY BECOME AT LEAST
ISOLATED EVERYWHERE WITH THE HIGHEST CONCENTRATION OF STORMS
BUILDING SOUTH. I ONLY ADJUSTED POPS A BIT TO ACCOUNT FOR CURRENT
TRENDS ALTHOUGH OVERALL AFTERNOON POPS WERE VERY CLOSE TO PREVIOUS
FORECASTER NUMBERS. TEMPS WERE TWEAKED DOWN A DEGREE OR TWO IN A FEW
SPOTS...MAINLY WHERE CLOUDS HAVE PERSISTED THIS MORNING OR WHERE
CONVECTION IS POPPING EARLY.

ANALYSIS OF MORNING SOUNDING AROUND THE REGION REVEALS ONLY SMALL
CHANCES FOR AN ISOLATED SEVERE STORM OR MICROBURST. WE WILL KEEP AN
EYE ON IT...BUT EXPECT MOST STORMS TO JUST CONTAIN FREQUENT
LIGHTNING, HEAVY DOWNPOURS, AND OCCASIONALLY GUSTY WINDS AT WORST.
