AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOBILE AL
322 PM CDT TUE AUG 21 2007
.SYNOPSIS...FOR THE CURRENT FORECAST...TWO MAJOR ITEMS TO TAKE CARE
OF IN THE SHORT TERM...WITH THE FIRST BEING THE WELL ABOVE SEASONAL
DAYTIME TEMPS...AND THE SECOND BEING ANY EFFECTS FROM DEAN.
CURRENTLY...TAKING A LOOK AT THE UPPER AIR PATTERN OVER THE CONUS AND
SURROUNDING AREAS...HIGH PRESSURE HAAS SHIFTED WEST...BECOMING
CENTERED OVER SOUTHERN GA. HIGH PRESSURE WAS HANGING TOUGH OVER THE
DESERT SOUTHWEST...WITH THE WEAK TROUGH SEPARATING THEM OVER TX AT
THIS TIME. DEAN IS MOVING OVER THE SOUTHERN BAY OF CAMPECHE...WITH
ANOTHER SHORTWAVE SYSTEM MOVING OVER THE EASTERN CARIBBEAN. AIRMASS
HAS DRIED OUT OVER THE NORTHWEST AND N-CENTRAL GULF COASTAL
AREAS...WITH PRECIP H20 LEVEL REPORTED BY FELLOW COASTAL SITES RANGING
FROM 1.25 AT KLIX TO 1.47 AT KVPS. LOW LEVEL HIGH PRESSURE IS STILL
FIRMLY IN CONTROL OF THE SOUTHEASTERN CONUS...WITH A FEW SHRA POPPING
UP OVER THE FA...BUT THESE HAVE BEEN CONFINED TO THE COAST.
&&
.SHORT TERM (TONIGHT THROUGH THURSDAY NIGHT)...GUIDANCE IS CONTINUING
TO ADVERTISE THE UPPER LEVEL HIGH MEANDERING WESTWARD...CENTERED OVER THE
SOUTHEASTERN THIRD OF THE CONUS BY FRIDAY MORN. DIGGING ENERGY OVER THE
WESTERN CONUS HAS CREATED A SHALLOW TROUGH OVER THE NORTHWESTERN TWO-
THIRDS OF THE US BY THIS TIME. THE WESTWARD BUILDING RIDGE WILL HELP
TO MAINTAIN THE DRY AIRMASS OVER THE NORTHEASTERN COAST INTO
WEDNESDAY NIGHT. THURSDAY INTO THE WEEKEND...GUIDANCE IS ADVERTISING
A SHORTWAVE WORKING ITS WAY SOUTH OVER THE CAROLINA/GA
SEABOARD...BRINGING IN SOME MOISTURE FROM THE EAST. NAM IS THE MORE
AGGRESSIVE SOLUTION WITH THE MOISTURE/PRECIP RETURNING.
FOR THE FORECAST...WITH THE DEWPOINTS VERIFYING A COUPLE OF DEGREES
BELOW THE DRYER MAV/GFS SOLUTION...HAVE TRANSLATED THIS INTO
TOMORROW. FOR TEMPS...WITH FLOW OFF THE GULF...THE GFS SOLUTION HAS
BEEN DOING BETTER HANDLING THE EFFECTS OF FLOW OFF THE GULF...SO HAVE
PRETTY MUCH STUCK WITH THE MAV/GFS SOLUTION...WITH SOME TWEAKING
HEAR AND THERE.
.LONG TERM...PREVIOUS LONG TERM FROM 445 PM...
THE UPPER RIDGE OVER THE SOUTHEAST BUILDS FARTHER WEST ALONG THE
CENTRAL GULF COAST REGION THROUGH WEDNESDAY...WITH A RETURN OF HOT
AND HUMID CONDITIONS THROUGH AT LEAST THURSDAY. AT LEAST THIS NEXT
PERIOD OF HEAT LOOKS TO BE A BIT SHORTER IN DURATION THAN THE LAST
ONE WE SAW DURING THE FIRST COUPLE WEEKS OF AUGUST. THE AFTERNOON
HEAT INDEX READINGS ARE FORECAST NEAR 108 AT MOST INLAND LOCATIONS
WEDNESDAY AND THURSDAY...AND WE WILL HAVE TO MONITOR THE TRENDS FOR A
POSSIBLE HEAT ADVISORY THROUGH AT LEAST THURSDAY. FOR NOW...WE
HIGHLIGHTED THE HIGHER HEAT INDEX READINGS IN THE FORECAST
PRODUCTS...AND WILL OUTLOOK THE HEAT STRESS POTENTIAL IN THE
HAZARDOUS WEATHER OUTLOOK AND A SPECIAL WEATHER STATEMENT THAT WE
WILL RELEASE LATER THIS MORNING. THE UPPER RIDGE OVER THE SOUTHEAST
BREAKS DOWN LATE IN THE WEEK AND WE SEE SCATTERED DIURNAL CONVECTION
INCREASE GOING INTO THE WEEKEND AS DEEP LAYERED MOISTURE SLIPS EAST
FROM THE WESTERN ATLANTIC UNDER THE WEAKENING RIDGE. TEMPS ALSO
MODERATE BY LATE WEEK AS WELL. /05
&&
.MARINE...STRONG HIGH PRESSURE WILL CONTINUE TO BUILD OVER THE NORTH
CENTRAL GULF THROUGH MUCH OF THE WEEK...INTERACTING WITH HURRICANE
DEAN THROUGH LATE WEDNESDAY. AS A RESULT A MODERATE EASTERLY WIND
FLOW WILL PERSIST THROUGH WEDNESDAY...THEN GRADUALLY DECREASE
THROUGH THE REMAINDER OF THE WEEK. NORTHWARD PROPAGATING SWELLS...
ORIGINATING FROM DEAN...WILL CONTINUE TO AFFECT THE COASTAL WATERS
THROUGH MIDDAY WEDNESDAY. THEREFORE A SMALL CRAFT ADVISORY HAS BEEN
ISSUED FOR THE OFFSHORE LEGS OF THE MARINE FORECAST WHERE SEAS UP TO
7 FEET CAN BE EXPECTED. SEAS WILL BEGIN TO SUBSIDE LATE WEDNESDAY
THROUGH THURSDAY. KC/GB
&&
.FIRE WEATHER...HIGH PRESSURE OVER THE SOUTHEASTERN US WILL MAINTAIN
A DRY AIRMASS OVER THE AREA INTO MID WEEK...WITH DAYTIME RELATIVE
HUMIDITY VALUES DROPPING INTO THE 35 TO 40 PERCENT RANGE AWAY FROM
THE COAST. AS HIGH PRESSURE SHIFTS EAST OF THE AREA THE LATTER HALF
OF THE WEEK...MOISTURE LEVELS ARE EXPECTED TO RISE...ALONG WITH
THE CHANCES FOR RAIN. THE HOT TEMPERATURES ARE EXPECTED TO CREATE
A VERY DEEP DAYTIME MIXING LAYER...WITH DAYTIME DISPERSIONS EXPECTED
TO BE VERY HIGH.

HURRICANE DEAN CONTINUES TO MOVE WEST ACROSS THE THE BAY OF CAMPECHE. LONG PERIOD SWELLS PROPAGATING NORTHWARD WILL PUSH MORE WATER THAN NORMAL ONTO AREA BEACHES OVERNIGHT. SMALL CRAFT OPERATORS SHOULD BE ADVISED THAT SWELL HEIGHTS BETWEEN 7 AND 10 FEET ARE EXPECTED OVERNIGHT...MAINLY BEYOND 20 MILES OFFSHORE. CLOSER IN...EXPECT 4 TO 6 FEET WAVE HEIGHTS. THERE IS AN INCREASED RISK OF DANGEROUS RIP CURRENTS AS WELL...IN THE SURF ZONE THROUGH TONIGHT. .DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH SUNDAY. ABOVE NORMAL TEMPERATURES AND HEAT INDEX VALUES WILL CONTINUE THROUGH THURSDAY AS HIGH PRESSURE REMAINS ANCHORED OVER THE CENTRAL GULF COAST. THE AFTERNOON HEAT INDEX WEDNESDAY AND THURSDAY IS EXPECTED TO AVERAGE BETWEEN 105 AND 110 DEGREES. HEAT INDEX VALUES THIS HIGH INDICATES A GREATER RISK FOR HEAT RELATED STRESS FOR PERSONS WORKING OUTSIDE. TEMPERATURES BY LATE WEEK WILL START TO MODERATE AS THE HIGH PRESSURE SYSTEM OVER THE DEEP SOUTH WEAKENS. THE POSSIBILITY OF DANGEROUS RIP CURRENTS CONTINUE ALONG THE BEACHES ON WEDNESDAY AS SWELLS PROPAGATE NORTHWARD FROM THE SOUTHERN GULF. PERSONS PLANNING A TRIP TO THE BEACH SHOULD HEED THE ADVICE OF THE LOCAL BEACH PATROL OR FLAG WARNING SYSTEMS. SCATTERED THUNDERSTORMS CAN BE EXPECTED ACROSS THE REGION THIS WEEKEND INTO EARLY NEXT WEEK. .SPOTTER INFORMATION STATEMENT... ACTIVATION OF STORM SPOTTERS AND EMERGENCY MANAGEMENT PERSONNEL IS NOT ANTICIPATED AT THIS TIME.
