AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOBILE AL
408 AM CDT THU JUN 26 2008

.SHORT TERM (TODAY AND TONIGHT)...UPPER AIR ANALYSIS SHOWS A BREAK
IN THE MID TO HIGH LEVEL RIDGE OVER THE LOWER MISSISSIPPI RIVER
VALLEY AND GULF COAST.  WITHIN THIS WEAKNESS/SHEAR
AXIS...FORECASTERS NOTE A GOOD DEGREE OF DEEP LAYER MOISTURE (FROM
1.7 TO NEAR 2 INCH PRECIPITABLE WATERS) AS LOW LEVEL/SURFACE RIDGE
OFF THE SOUTHEAST COAST IMPARTS SOUTH TO SOUTHWEST FLOW OFF THE
GULF.  CONSIDERING THESE PLAYERS ALONG WITH DESTABILIZATION OF THE
LOCAL AIRMASS DURING THE DAY TODAY...THE STAGE APPEARS SET FOR
THUNDERSTORMS TO INITIATE ON WEAK MESOSCALE BOUNDARIES/SEA BREEZE
THROUGH THE COURSE OF THE DAY.  FORECASTERS ANTICIPATE ISOLATED
THUNDERSTORMS TO FORM UP ALONG THE COASTAL ZONES THIS MORNING WITH
AN INCREASE IN COVERAGE NORTHWARD.  THE ENVIRONMENT IS SUPPORTIVE OF
WATERSPOUTS AS WELL AND IF YOUR HEADING TO THE BEACHES THIS
MORNING...BE ON THE LOOKOUT FOR THESE.  WATERSPOUTS SHOULD SHOW A
DISSIPATING TREND BEFORE APPROACHING SHORE.

ANOTHER ITEM...OFFERING UP QUITE A CHALLENGE ON THE FORECAST PLATE
IS TEMPERATURES...MAINLY IN THE DAYTIME HIGHS.  WITH THE WEAKER
HEIGHTS ALOFT AND DEEPER LAYER MOISTURE...HAVE OPTED TO STAY VERY
CLOSE TO THE MAV MOS NUMBERS FOR THE OFFICIAL NUMBERS.  WE DID EDGE
SLIGHTLY ABOVE THE GUIDANCE IN THE NORTHEAST ZONES TODAY...WHERE
JUST MAY BE ENOUGH UPPER RIDGING TO AID IN COMPRESSIONAL WARMING AS
SUN BREAKS THROUGH CLOUDS BEFORE THUNDERSTORMS BRING TEMPERATURES
DOWN.  THAT IS THE CHALLENGE.  THUNDERSTORMS COULD BE STRONG WITH A
FEW POSSIBLY STRENGTHENING...BRIEFLY TO SEVERE LEVELS.  OUTSIDE OF
LOCALLY HEAVY RAINS AND FREQUENT LIGHTNING...STORMS WILL BE CAPABLE
OF PRODUCING BRIEF STRONG WINDS AND SMALL HAIL.  WITH THE WET BULB
ZERO HEIGHTS FROM 12.5 TO 13 KFT...STORMS THAT DEVELOP HIGH
REFLECTIVITY (55+ DBZ AT 26+ KFT) COULD PRODUCE PENNY SIZED HAIL AS
WELL AS BRIEF DAMAGING WINDS...UPON CORE COLLAPSE IN THESE STORMS.

TODAYS WET MICROBURST RISK IS MODERATE. /10

&&

.LONG TERM (FRIDAY THROUGH WEDNESDAY)...THE WEAK TROPICAL WAVE
CONTINUES WESTWARD ACROSS THE GULF ON FRIDAY WITH DEEP TROPICAL
MOISTURE OVER THE FORECAST AREA REFLECTED IN HIGH PRECIPITABLE WATER
VALUES NEAR TWO INCHES.  AN UPPER JET MAX DIVES OUT OF THE WESTERN
CANADIAN PROVINCES AND INTO THE NORTHERN PLAINS THROUGH SATURDAY
EVOLVING INTO A LONGWAVE TROF OVER THE EASTERN STATES...WITH A
SURFACE LOW MOVING ACROSS THE GREAT LAKES ON FRIDAY THEN EVOLVING
INTO A SLOW MOVING OCCLUDED SYSTEM OVER QUEBEC ON SUNDAY.  WHILE A
SURFACE RIDGE OVER THE NORTHERN GULF MAINTAINS A LIGHT ONSHORE
FLOW...A WEAKENING FRONT ASSOCIATED WITH THE SURFACE LOW SLOWLY
MOVES SOUTHWARD INTO THE SOUTHEAST STATES...EVENTUALLY MOVING
THROUGH THE FORECAST AREA ON MONDAY.  THE PATTERN SUPPORTS STAYING
WITH GOOD CHANCE TO LIKELY POPS THROUGH SUNDAY FOR THE MAINLY
DAYTIME AND EARLY EVENING CONVECTION...THEN CHANCE POPS FOR MONDAY
AS THE WEAKENING FRONT MOVES THROUGH.  CHANCE POPS CONTINUE FOR THE
REMAINDER OF THE FORECAST AS THE FRONT LINGERS NEAR THE COAST AND
DISSIPATES WHILE A PREDOMINATELY LIGHT ONSHORE FLOW RESUMES.
TEMPERATURES WILL BE NEAR SEASONABLE LEVELS THROUGH THE PERIOD. /29

&&

.MARINE...VERY LITTLE CHANGE IN THE SURFACE PATTERN WITH A RIDGE OF
HIGH PRESSURE LOOKING TO PERSIST FROM THE BAHAMAS INTO THE CENTRAL
GULF INTO THE WEEKEND. WINDS LOOK TO VARY FROM SOUTH TO SOUTHWEST
RANGING FROM 5 TO 15 KNOTS THROUGH MOST OF THE PERIOD. A WEAK
SURFACE TROF MAY EASE INTO THE DEEP SOUTH MONDAY...IMPARTING MORE OF
A WESTERLY COMPONENT TO THE WINDS THEN. LITTLE CHANGE IN SEAS IS
EXPECTED. MARINERS SHOULD PLAN FOR THUNDERSTORMS. WATERSPOUT
ACTIVITY ALSO A POSSIBILITY...ESPECIALLY IN THE MORNINGS. /10

&&

.FIRE WEATHER...NO CONCERNS AS AFTERNOON HUMIDITY LEVELS REMAIN WELL
ABOVE CRITICAL LEVELS THROUGH NEXT WEEK. /29
