.DISCUSSION...
/ISSUED 317 AM CDT WED AUG 3 2011/
MEMORABLE DAY OF HEAT YESTERDAY WITH RECORD HIGH TEMPERATURES SET
AT JLN/SGF/UNO AND RECORD WARM LOW TEMPERATURE RECORDS SET AT
JLN/SGF/UNO/VIH. RECORD HIGH TEMPERATURES FOR AUGUST WERE SET AT
SGF/JLN. WHILE WE WON/T QUITE REACH THESE HALLOWED RECORDS...WE
WILL REMAIN ENTRENCHED IN A HEAT WAVE FOR AT LEAST THE NEXT COUPLE
OF DAYS.
CURRENTLY...IT IS STILL QUITE WARM ACROSS THE AREA. TEMPERATURES
OVERALL ARE IN THE LOWER TO MIDDLE 80S. A WEAK COLD FRONT IS
MOVING THROUGH THE OZARKS AT THIS TIME...JUST ABOUT ALONG A LINE
FROM ROLLA TO SPRINGFIELD TO JOPLIN. VERY LITTLE IN THE WAY OF
CLOUD COVER ASSOCIATED WITH THIS FRONT...THOUGH SCATTERED CUMULUS
CONTINUES TO FESTER ALONG THE MO/ARK BORDER. INTERS TINGLY...
SURFACE DEWPOINTS ARE RISING BEHIND THE FRONT...WITH READINGS
RISING INTO THE MID 70S. CAN/T RULE OUT A FEW SHOWERS POPPING UP
OVER THE NEXT FEW HOURS ACROSS SOUTHERN MO.
TODAY AND THURSDAY...JUDGING FROM AREA 88D VERTICAL WIND
PROFILES...THE FRONT MOVING INTO THE AREA IS RATHER SHALLOW. AS
SUCH...THERE ARE CONCERNS THE FRONT COULD BECOME RATHER DIFFUSE
DUE TO MIXING. 850MB TEMPS WILL DROP BACK AROUND 2C TO 3C TODAY
AND HAVE SCALED TEMPERATURES BACK COMPARED TO YESTERDAY/S
EXTRAORDINARY VALUES. 850MB TEMPS ARE COMPARABLE TO SUN/MON...IN
THE MID 20S C...AND HAVE FOLLOWED THE ASSOCIATED HIGHS
ACCORDINGLY. THIS WILL RESULT IN TEMPERATURES RANGING FROM THE
MID/UPPER 90S ACROSS CENTRAL MO/EASTERN OZARKS TO THE 100 TO 105
DEGREE RANGE ELSEWHERE. WARMEST CONDITIONS WILL BE SOUTH OF
HIGHWAY 60 AND WEST OF HIGHWAY 65. DEWPOINTS WILL BE HIGHER
TODAY...ESPECIALLY ALONG AND NORTH OF HIGHWAY 60...SO WHILE AIR
TEMPS WILL BE A TAD LOWER IT WILL FEEL A BIT MORE MUGGY. FOR
THURSDAY...AIR TEMPS WILL LIKELY DROP BACK A FEW MORE DEGREES...
HOWEVER WE WILL REMAIN ON THE MUGGY SIDE...KEEPING HEAT INDEX
VALUES IN THE 100 TO 110 RANGE. WILL KEEP THE GOING HEAT HEADLINES
AS IS...THOUGH IT IS PLAUSIBLE THAT PORTIONS OF CENTRAL MO MAY BE
NEED TO BE PRUNED FROM THE WARNING THURSDAY IF CONFIDENCE IN
SLIGHTLY COOLER CONDITIONS INCREASES.
AS FAR AS RAIN CHANCES GO TODAY AND THURSDAY...CANNOT RULE OUT
ISOLATED CONVECTION TODAY...WITH THE POTENTIAL FOR BETTER COVERAGE
THURSDAY AFTERNOON. WHILE SHEAR IS WEAK...SHOULD SEE DECENT LAPSE
RATES IN THE LOW LEVELS WHICH WILL SUPPORT A FEW POTENTIALLY
SEVERE DOWNBURSTS. COVERAGE OF ANY SEVERE WILL BE ISOLATED.
FRIDAY ONWARD...00Z OPERATIONAL MODEL OUTPUT CONTINUES TO SUPPORT
A SLOW WESTWARD RETROGRESSION OF THE UPPER LEVEL RIDGE OF HIGH
PRESSURE. THIS WILL RESULT IN TEMPERATURES COOLING SLIGHTLY EACH
DAY...BACKING DOWN TO AT/JUST ABOVE AVERAGE BY EARLY NEXT WEEK.
AS NORTHWEST FLOW BEGINS TO DEVELOP OVER THE REGION...PERIODIC
CHANCES FOR SHOWERS AND STORMS WILL SLOWLY INCREASE EACH DAY.
CONFIDENCE IN TIMING ANY PARTICULAR WAVES IN THIS NORTHWEST FLOW
IS FRUITLESS AT THIS POINT AND HAVE BROAD BRUSHED LOW CHANCES FOR
RAIN EACH DAY. WILL REFINE WITH FUTURE FORECASTS AS CONFIDENCE
INCREASES.
GAGAN
&&
.AVIATION...
FOR THE 06Z TAFS...LITTLE CHANGE FROM THE PREVIOUS FORECAST AT
THIS TIME DESPITE A WEAKENING COLD FRONT MOVING SOUTH ACROSS THE
REGION. VFR CONDITIONS ARE EXPECTED TO PREVAIL THROUGH THE
OVERNIGHT AND INTO WEDNESDAY. THE FRONT IS EXPECTED TO WASH OUT
OVER THE ARE AND COULD PROVIDE A FOCUS FOR SOME THUNDERSTORMS
WEDNESDAY BUT COVERAGE AND TIMING REMAIN UNCERTAIN AND HAVE OPTED
TO GO WITH CB FOR GENERALLY 12Z AND ON FOR TOMORROW.
