AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOBILE AL
331 PM CDT WED AUG 5 2009

.SHORT TERM...(TONIGHT THROUGH FRIDAY NIGHT)TAKING A LOOK AT THE
CURRENT SITUATION OVER THE CONUS AND SURROUNDING AREAS...UPPER LEVEL
HIGH PRESSURE WAS ANALYZED OVER NM WITH A RIDGE STRETCHING
NNW OVER/WEST OF THE ROCKIES. A CLOSED LOW WAS ANALYZED OFF THE
CALIFORNIA COAST...WITH ANOTHER NEAR HUDSON BAY. AN UPPER TROUGH
STRETCHED SOUTH OVER EASTERN CA/CONUS...BISECTING THE UPPER RIDGE
STRETCHING EAST OVER THE GULF OF MEX FROM THE NM RIDGE. OF IMMEDIATE
INTEREST TO THE FA IS A SHORTWAVE SYSTEM MOVING OVER THE LOWER MISS
RIVER VALLEY AND WESTERN AREAS OF THE SOUTHEASTERN CONUS. THIS HAS
HELPED TOUCH OFF SCATTERED TSRA OVER THE SOUTHEASTERN HALF OF THE
FA...ROUGH ALONG AND SOUTHEAST OF I-65. ABUNDANT MOISTURE IS PRESENT
IN THE LEVELS AROUND 10K AND BELOW IS HELPING WITH THE
INSTABILITY...WITH A BAND OF BETTER MOISTURE STRETCHING FROM THE LA
GULF COAST NW OVER ATLANTA. ALSO HELPING IS AN OUTFLOW BOUNDARY
WORKING ITS WAY SOUTH OVER THE FA FROM CONVECTIVE ACTIVITY WHICH
MOVED SOUTH OVER E-RN AR/W-RN TN/N-RN MS EARLY THIS MORNING....WHICH
WAS GENERATED ALONG A STATIONARY FRONT STRETCHING FROM THE TX/OK
PANHANDLE EASTWARD TO THE MID ATLANTIC REGION.

FOR TONIGHT THROUGH THURSDAY...THE SHORTWAVE ENERGY CAUSING THE
CURRENT WEATHER WILL MOVE THROUGH ...AS MORE SHORTWAVE ENERGY MOVES
THROUGH THE NORTHERN END OF THE EASTERN TROUGH...TILTING THE UPPER
TROUGH OVER THE SOUTHEASTERN CONUS A BIT. THE UPPER LOW OFF THE
CALIFORNIA COAST ORGANIZES AND SWINGS EAST...SHIFTING THE UPPER RIDGE
OVER NM EASTWARD. AM STILL EXPECTING GULF BREEZE INDUCED ACTIVITY FOR
THURSDAY INTO THURSDAY EVENING...SO HAVE WENT ABOVE THE GFS/MAV
GUIDANCE...MORE IN LINE WITH THE NAM/MET.

THURSDAY NIGHT INTO FRIDAY NIGHT...GUIDANCE DIVERGES...WITH GFS
ADVERTISING DRIER AIR TO THE NORTH PUSHING A BIT FARTHER SOUTH AS
SURFACE HIGH PRESSURE MOVES FROM THE NORTHERN PLAINS TO THE MID
ATLANTIC REGION. AM AGAIN LEANING TOWARDS THE NAM/MET
SPECIFICS...ESPECIALLY ALONG THE COAST...AS FEEL WITH THE DRIER
NORTHERLY AIR WILL LOSE ITS PUSH AS THE DRIVING SURFACE HIGH MOVES
OVER...THEN EAST OF THE MID ATLANTIC REGION FRIDAY INTO FRIDAY NIGHT.
BOTH NAM AND GFS HAVE SOUTHERLY FLOW OVER THE SOUTHERN HALF OF THE
LAND FA...HELPING TO RE-ENFORCE THIS DECISION. THE NM UPPER RIDGE
CONTINUES TO GET PUSHED EAST AS THE WESTERN UPPER LOW...SO AM
EXPECTING TEMPS TO BE A BIT ABOVE SEASONAL FOR FRIDAY...ESPECIALLY
NORTHERN AREAS OF THE FA

.LONG TERM...SATURDAY ON...FOR THE WEEKEND...MEDIUM RANGE GUIDANCE
CONTINUES TO ADVERTISE THE UPPER RIDGE...CENTERED OVER THE
SOUTHEASTERN CONUS BY SATURDAY MORN...CONTINUING TO GET PUSHED EAST A
BIT BEFORE BECOMING CENTERED OVER THE NC/SC/GA/FL ATLANTIC COAST BY
MONDAY MORN. SURFACE HIGH PRESSURE RE-ESTABLISHES ITSELF OVER THE
NORTHERN GULF COAST...PROVIDING SOUTHERLY FLOW OVER THE AREA FOR THE
WEEKEND INTO THE EARLY PART OF THE COMING WEEK.

&&

.MARINE...A GENERAL WEST TO SOUTHWEST FLOW IS EXPECTED IN THE NEAR
TERM. HOWEVER...CONVECTION DEVELOPING OVER THE COASTAL COUNTIES
MOVING OFFSHORE WILL TEMPORARILY ALTER WINDS AND SEAS FOR THE REST OF
THIS AFTERNOON INTO TONIGHT. WINDS AND SEAS WILL BE LOCALLY HIGHER
IN AND NEAR SHOWERS AND THUNDERSTORMS. A PREDOMINATE SOUTHEASTERLY
FLOW DEVELOPS BY FRIDAY AND PERSISTS INTO EARLY NEXT WEEK AS HIGH
PRESSURE STRENGTHENS OVER THE SOUTHEAST STATES INTO THE SOUTHEAST
ATLANTIC. OUTSIDE OF CONVECTION...SEAS ARE EXPECTED TO AVERAGE
BETWEEN 1 TO 2 FT THROUGH THE PERIOD. 34/JFB

&&

.FIRE WEATHER...THE AIRMASS OVER THE AREA WILL DRY OUT SOMEWHAT...ESPECIALLY
OVER NORTHERN SECTIONS...AS A SURFACE HIGH PASSING WELL NORTH OF THE AREA
TRIES TO PUSH A WEAK FRONT TOWARDS THE NORTHERN GULF COAST TONIGHT INTO
THURSDAY NIGHT. A TEMPORARY SWITCH IN THE LOW LEVEL FLOW TO NORTHERLY WILL
OCCUR LATE THURSDAY INTO FRIDAY...BUT AS LOW LEVEL HIGH PRESSURE STRETCHING
WEST OVER THE NORTHERN GULF OF MEXICO REGAINS CONTROL...LOW LEVEL FLOW WILL
RETURN TO SOUTHERLY BY SATURDAY.
