AREA FORECAST DISCUSSION

.DISCUSSION...
OVERALL UPPER LEVEL PATTERN CHARACTERIZED BY THE UPPER RIDGE OVER
THE DESERT SW UP THROUGH THE WRN CENTRAL PLAINS...AND A WEAK
SHORTWAVE OVER THE GREAT LAKES REGION. BASE OF THE RESIDENT UPPER
TROF THAT HAS BEEN PRESENT OVER THE ERN U.S. OVER THE LAST SEVERAL
DAYS HAS BECOME CUT OFF AND IS READILY SEEN IN THE WV IMAGERY OVER
SRN MS/AL. WEAK COLD FRONT ASSOCIATED WITH THE GREAT LAKES
SHORTWAVE IS CURRENTLY DRAPED ACROSS NRN OK AND IS SERVING AS A
FOCUS FOR CONVECTION ALONG AND AHEAD OF THE FRONT. WE ARE EVEN
SEEING SOME VERY LIGHT SHWRS ACROSS OUR NRN SECTIONS. THIS
ACTIVITY MAY INCREASE MOVING INTO THE DAYLIGHT HOURS TODAY...
ALTHOUGH THE FRONT WILL BEGIN TO LOSE ITS SWD PUSH AS ITS
ASSOCIATED SHORTWAVE DEPARTS TO THE E. AT ANY RATE...HAVE
CONTINUED WITH THE ONGOING SLIGHT CHANCE POPS AND HAVE EVEN
EXTENDED THEM A LITTLE FURTHER SWD.

FOR THE REMAINDER OF THE WEEKEND AND INTO THE WORK WEEK...GENERAL
WEAKNESS ON THE ERN PERIPHERY OF THE RIDGE...AND THE RETROGRADING
UPPER LOW /CURRENTLY OVER MS/AL/ WILL LEAD TO CHANCES FOR DAILY
ISOLD SHWRS/TSTMS. BY MIDWEEK...THE UPPER LOW IS EXPECTED TO BE
OVHD...WHICH WILL AID IN PUMPING DEEP-LAYER MOISTURE INTO THE
REGION. THIS...COMBINED WITH LIFT FROM THE LOW ITSELF AND AN
ENHANCED SEA BREEZE WILL BRING BETTER CHANCES FOR CONVECTION FOR
THE LATTER HALF OF THE WORK WEEK.

FOR TEMPS...WITH NO COLD FRONT/TROF OR OPPRESSIVE UPPER RIDGE TO
TIP US EITHER SIDE OF LATE AUGUST/EARLY SEPTEMBER NORMALS...WE
LOOK TO TRACK RIGHT DOWN THE SEASONAL NORMAL PATH THROUGHOUT THE
FCST PD. HAVE STAYED VERY CLOSE TO GUIDANCE WITH REGARD TO TEMPS
AS A RESULT. /12/
