AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
301 PM CDT FRI JUL 1 2005

.SHORT TERM...FINALLY SHRA AND TSRA LOOK TO OCCUR OVER THE REGION
AGAIN. SHRA AND TSRA ASSOCIATED WITH A MCS LAST NIGHT GOT INTO THE
CWA EARLY THIS MORNING LAID OUT AN OUTFLOW BNDRY THAT MOVED THROUGH
THE CWA. NUMEROUS ADDITIONAL TSRA DEVELOPED ALONG AND OUT AHEAD OF
THIS BNDRY. THIS BNDRY AND NOT NECESSARILY THE FRONT WILL STALL OUT
ACROSS STHRN AND WSTRN PORTIONS OF THE CWA. THIS COULD LEAD TO
ADDITIONAL SHRA AND TSRA TONIGHT AND TOMORROW.

TONIGHT LOOK FOR THE ACTIVITY TO BEGIN TO WANE BY SUNSET. WITH THE
EXCEPTION OF THE 06Z NAM THE MDLS DID NOT HANDLE THE SITUATION TODAY
WELL...ESPECIALLY THE ACTIVITY TO THE WEST. ACCORDING TO THE 12Z H5
ANALYSIS AND WHAT THE MDLS ARE SHOWING WE WILL BE IN A VERY WEAK NW
FLOW REGIME. THIS WILL TRY AND SEND A S/W WAVES ACROSS THE REGION
TONIGHT AND THROUGH THE WEEKEND. AS OUR BNDRY CONTINUES TO PUSH
SOUTH TONIGHT LOOK FOR IT TO STALL OUT SOMEWHERE OVER THE SWSTRN
HALF OF THE CWA. AT THE SAME TIME THE FIRST OF A COUPLE OF S/W WILL
BEGIN TO TRAVERSE ACROSS THE REGION. WHEREVER THE BNDRY FINALLY STALLS
WILL BE WHERE THE BEST CHANCE FOR RAIN WILL BE OVER THE NEXT 36HRS.
PWS WILL REMAIN ATA 2 AND H85 THETA E VALUES WILL BE OVER 340K.
WITH THAT THERE WILL LIKELY BE ANOTHER MCS TO DEVELOP TONIGHT AND
LOOKS TO PUSH ACROSS THE WESTERN HALF OF THE CWA. WITH THAT I WILL
TAPER MAY POPS FROM WEST TO EAST. AS FOR LOWS EXPECTING PRETTY GOOD
COVERAGE OF CLOUDS TONIGHT SO NOT EXPECTING LOWS TO DROP GET MUCH
LOWER THAN THE MID 70S IN MOST LOCALS.

TOMORROW...COULD SEE MUCH OF THE SAME AS NUMEROUS BNDRIES WILL
LIKELY BE OVER THE AREA FROM TDY AND TONIGHTS ACTIVITY. AS WE HEAT
UP TOMORROW THESE BNRDIES WILL BE THE FOCUS FOR SHRA AND TSRA
DEVELOPMENT. ALSO IN THE NW FLOW ALOFT ANOTHER S/W WILL PUSH DOWN
AND THIS WILL BRING THE NEEDED UPPER LEVEL ENERGY. AS WITH
TONIGHT...THE BEST CHANCE FOR RAIN WILL BE NEAR AND TO THE SOUTH AND
WEST OF THE STALLED FRONT. HIGHS TOMORROW WILL BE COOLER THAN WE
HAVE SEEN IN PAST FEW DAYS AS NUMEROUS CLOUDS AND COOLER H85
TEMPS...AROUND 18C...SUGGEST HIGHS WONT GET MUCH ABV THE UPPER 80S
TO NEAR 90. /CAB/

.LONG TERM...SUNDAY AND MONDAY
GFS HAS CONVECTIVE FEEDBACK PROBLEM AND DEEPENS A SURFACE LOW ALONG
BOUNDARY. BELIEVE THERE MAY BE A SATURDAY NIGHT...EARLY MORNING
SUNDAY MCS IN THE AREA...BUT DONT TRUST HOW THIS WILL PLAY OUT
SUNDAY AFTERNOON AND EVENING. WILL KEEP POPS RELATIVELY HIGH AND
TEMPERATURES A LITTLE LOWER BECAUSE OF THE CHANCE FOR MORNING
PRECIPITATION.

MONDAY TOUGH TO CALL...ESPECIALLY TEMPERATURE WISE.  IF SUFFICIENT
DRYING AND PUSH FROM FRONT DOES INDEED TAKE PLACE...COULD ACTUALLY
BE WARMER DUE TO STRONG INSOLATION AND NO CONVECTION.  JUST TOOK A
WILD GUESS ON THIS BUT HAD IT DRIER NORTH AND WETTER SOUTH.

TUESDAY AND WEDNESDAY...GFS...NAM...AND ECMWF ALL SHOW BLOB OF
TROPICAL MOISTURE IN NORTHWEST CARIBBEAN MOVING NORTH ACROSS GULF AND
MOVING INTO CENTRAL GULF COAST AREA TUESDAY. REGARDLESS OF HOW THIS
EVOLVES FROM TPC/NHC PERSPECTIVE...LOOKS LIKE 2 TO 2.4 PRECIPITABLE
WATER AIR CAN BE PULLED INTO FORECAST AREA. GOES DPI PW SUGGESTS THAT
THIS AIR IS ALREADY IN PLACE...WITH OBSERVED VALUES APPROACHING 60
MM. WENT NEAR HIGHEST GFS ENSEMBLE MEMBERS FOR POPS...ESPECIALLY
SOUTH. ALSO...TRIMMED TEMPERATURES CLOSER TO 90 AND EVEN UPPER 80S
SOUTH GIVEN EARLY CONVECTION AND PLENTY OF CLOUD COVER THAT WOULD
LIKELY OCCUR IN THAT REGIME.

THURSDAY AND FRIDAY...PROBABLY DRIES OUT SOMEWHAT DURING THE LATE
WEEK BUT REALLY NOT MUCH TO FOCUS ON. GUIDANCE SUGGESTS STRONG UPPER
HIGH OVER FLORIDA AND SOUTHERN PLAINS WITH WEAKNESS IN RIDGE ALONG
TEXAS COAST. THUS...PROBABLY ENOUGH EXCUSE TO LEAVE CLIMO POPS. /CRAVEN/
