.DISCUSSION...
/355 PM CDT TUE JUL 26 2011/
CENTER OF RIDGE ALOFT...NOW IN THE PROCESS OF OSCILLATING BACK TO
THE E...WILL ALSO RESULT IN RISING HEIGHTS OVERHEAD THRU THURSDAY
WITH SOME DEGREE OF MAINTENANCE OF THESE HEIGHTS INTO FRIDAY AS
RIDGE AMPLIFIES A BIT MORE TO OUR W GIVING US A SLIGHT NW FLOW BY
FRIDAY. THIS WILL RESULT IN INCREASING LEVELS OF HEAT WITH
PERSISTENT LEVELS OF HUMIDITY OVER THE AREA THRU AT LEAST
THURSDAY...ALTHOUGH WE ARE NOW GETTING INTO THAT TIME OF YEAR WHERE
IN THE ABSENCE OF A FRONT TO POOL HIGHER DEWPOINT AIR...INCREASED
DEWPOINTS DUE TO EVAPOTRANSPIRATION SEEM TO BE BECOMING LESS AND
LESS LIKELY AS THIS HOT AND...FOR MOST AREAS...DRY PERIOD DRONES
ON. WHILE THIS MAY SEEM LIKE SOME WELCOME RELIEF...THIS WILL ONLY
TEND TO ALLOW MAX AMBIENT TEMPS TO GO HIGHER WITH THE OVERALL EFFECT
ON ANY DECREASED HEAT INDEX VALUES BEING NULL.
WILL MANTAIN THE CURRENT SUITE OF HEAT PRODUCTS WITH ONE CHANGE...
EXPANDING THE HEAT WARNING FURTHER N TO INCLUDE THE REST OF NERN MO
AND W CNTRL IL AS THEY HIT AROUND 105 ON THE HEAT INDEX MONDAY SO
THIS WILL BE RETROACTIVE TO THEN. ALL HEADLINES GO UNTIL THURSDAY
EVENING.
PCPN CHCS AFTER TODAY WILL REVOLVE AROUND APPROACH OF CDFNT FROM THE
N BEGINNING THURSDAY AS ELSEWHERE THE ATMOSPHERE SHOULD BE TOO
CAPPED. MCS OVER IA ON WEDNESDAY NIGHT SHOULD EJECT AN OUTFLOW SWD
INTO THE NRN FA ON LATE WEDNESDAY NIGHT AND INTO THURSDAY AND THIS
MAY RESULT IN SOME PCPN FOR THAT AREA BEFORE OUTFLOW WASHES OUT
LATER IN THE DAY. A REPEAT OF THIS SCENARIO IS THEN EXPECTED
THURSDAY NIGHT AND INTO FRIDAY...BUT FURTHER S AND DEEPER INTO THE
FA...AS THE FRONT SAGS S AND OUTFLOWS WILL INDUCE THIS BEHAVIOR EVEN
MORE. BECAUSE OF THIS ON FRIDAY FOR A MUCH LARGER SECTION OF THE
FA...WILL REFRAIN FROM TEMPORAL EXPANSION OF HEAT HEADLINES AT THIS
TIME.
FOR THE MEDIUM RANGE (FRIDAY NIGHT - TUESDAY)...RIDGE ALOFT WILL
DOMINATE MUCH OF THE CNTRL AND SRN CONUS THRU-OUT THIS PERIOD...IT
JUST COMES DOWN TO WHERE THE CENTER OF IT WILL BE AT ANY GIVEN
PERIOD WHICH WILL...IN TURN...INFLUENCE ABILITY OF CDFNTS TO
PENETRATE SWD INTO OUR AREA OR NOT. IT STILL LOOKS LIKE THE CENTER
OF THIS RIDGE ALOFT WILL BE IN THE PROCESS OF RETROGRADING BACK TO
THE W AT THE BEGINNING OF THIS PERIOD WHICH WILL ALLOW A SFC CDFNT
TO PENETRATE SWD INTO OUR REGION AND THEN LINGER AND/OR DISSIPATE.
HAVE MAINTAINED CHANCE POPS THRU SATURDAY AFTERNOON AND MAY CONTINUE
INTO SATURDAY NIGHT AND SUNDAY DEPENDING ON EXACTLY HOW FAST THE
FRONT LOSES ITS IDENTITY. OTHERWISE...THE REMAINDER OF THIS PERIOD
LOOKS MAINLY DRY. BEGAN THE PERIOD FAVORING TEMPS THAT ARE NEAR THE
ENSEMBLE MEAN...WHICH INCIDENTALLY IS ALSO CLOSE TO THE
CLIMATOLOGICAL AVERAGE...THANKS TO PRESENCE OF FRONT AND ENHANCED
RAIN CHANCES...AND THEN ADJUSTED UPWARD TO AOA THE HI MEMBER OF THE
ENSEMBLES FOR EARLY NEXT WEEK. ANY RELIEF WE DO GET FROM THE HEAT
FOR LATE THIS WEEK APPEARS TO BE BRIEF WITH NEAR PERPETUAL
EXCEEDANCE OF 100F ON THE HEAT INDEX EXPECTED EVEN DURING THIS
/RELIEF/...WITH ANOTHER BUILD-UP EXPECTED FOR MUCH OF NEXT WEEK.
ONLY CURE FOR THIS HEAT WAVE MAY BE ARRIVAL OF AUTUMN.
