AREA FORECAST DISCUSSION...UPDATED AVIATION

.DISCUSSION...
/500 AM CDT MON JUN 27 2011/
EARLY THIS MORNING...NEAR ZONAL H500 FLOW EXISTED ACROSS THE AREA
WITH A H500 RIDGE EXPANDING OVER THE S CNTRL CONUS. A SFC FRONTAL
BOUNDARY EXTENDS W-E FROM A PARENT LO OVER S CNTRL KS THRU SRN MO
AND INTO SRN IL. THIS FRONT WAS A WRMFNT UNTIL YET ANOTHER SERIES
OF TSRA COMPLEXES ROLLED THRU AND HAS EFFECTIVELY SUPPRESSED ANY NWD
MOVEMENT...AT LEAST TEMPORARILY. A VEERED 60KT H850 JET EXISTED
NOSING INTO SWRN MO AND HAS HELPED TO EXPAND SRN EDGE OF CONVECTION
WITH RATHER SOLID AREAS OF RAIN AND TSRA OVER CNTRL AND NRN MO AND
MUCH OF IL. OUTFLOW BOUNDARY HAS BEEN SHOVED TO FAR SRN MO AND SRN
IL. TEMPS HAVE COOLED INTO THE LOW-MID 60S WHERE RAIN HAS FALLEN
AND TO A LESSER EXTENT ELSEWHERE IN THE SRN FA BEHIND THE OUTFLOW.
PERSISTENT CONVECTION BEING MAINTAINED BY LO LEVEL JET IN THE S...
MCV IN THE N WITH FRONTOGENETICAL FORCING AND OLD MCV. MUCH OF THIS
SHOULD PERSIST AT LEAST INTO MID MORNING BEFORE BEGINNING TO FADE
AND/OR EXIT THE FA. CONVECTIVE DEBRIS CLOUDS LATER THIS MORNING
WILL PREVENT TEMPS FROM GETTING TOO WARM TOO QUICKLY FOR MANY
AREAS...BUT WITH DIMINISHING PCPN COVERAGE...AND UPSTREAM LO PRES
WAVE...FRONT SHOULD FIND THE MOTIVATION TO BEGIN A TOO LITTLE...TOO
LATE NWD ADVANCE AND WILL LIKELY FALL SHORT OF CLEARING THE NRN FA
BEFORE CDFNT ARRIVES THIS AFTERNOON AND MOVES THRU THIS EVENING TO
SWEEP IT ALL AWAY. FAVORED COOLER METMOS TEMPS MUCH OF THE AREA...
AND WENT BELOW METMOS IN THE FAR NRN FA...WHERE WRM FROPA IS
DOUBTFUL.
NEW TSRA DEVELOPMENT SHOULD OCCUR BY MID AFTERNOON ALONG CDFNT AND
WILL PROBABLY BE A BIT FURTHER S AT INITIATION TIME THEN ORIGINALLY
ANTICIPATED. THIS WILL THEN CONTINUE ITS DEVELOPMENT THRU THE
EVENING HOURS AS THE CDFNT IS EXPECTED TO CLEAR THE SRN FA BY
MIDNIGHT TONIGHT. AFTERNOON DE-STABILIZATION...WHILE EXPECTED
ENOUGH TO RE-IGNITE TSRA ALONG FRONT...THE DEGREE TO WHICH IS IN
QUESTION AND PROBABLY WON/T REACH ITS FULL POTENTIAL.
NEVERTHELESS...SEVERE STORMS ARE EXPECTED AGAIN WITH CD FROPA THRU
THIS EVENING.
THE PERIODS OF HEAVY RAINFALL OVER THE PAST COUPLE OF DAYS HAVE
TAKEN THEIR TOLL AND WITH MORE LAST NIGHT...HAVE EXTENDED THE FFA
THRU THIS EVENING OVER MUCH OF THE FA...EXPANDING IT ALSO INTO CNTRL
MO WHERE A COUPLE ROUNDS OF HEAVY RAINFALL WILL CATCH THEM UP THIS
MORNING.
QUIET WX FINALLY ARRIVES BEGINNING TUESDAY...WITH A DANDY OF A DAY
EXPECTED WITH HIGHS IN THE LO-MID 80S AND LO HUMIDITY. AMPLIFYING
H500 FLOW HEADING INTO MID WEEK WILL HELP ALLOW THIS FRONT TO DIVE
WELL S OF THE FA AND STAY TO THE S UNTIL AT LEAST THURSDAY...WHEN IT
WILL PASS TO OUR N AS A SHORT WRMFNT. SHOULD SEE PERIOD OF MAINLY
DRY WX CONTINUE THROUGH THE END OF THE WORK WEEK...BUT WILL COME AT
A PRICE...WITH RETURN OF VERY WARM AND HUMID WX AND MAY MEAN SOME
HEAT ADVISORIES WILL BE NEEDED.
