AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOBILE AL
230 AM CDT FRI JUL 18 2003

.SHORT TERM...PERSISTENT TROF CONTINUES OVER THE EASTERN U.S.
WITH STRONG UPPER RIDGE HOLDING ACROSS MUCH OF THE SOUTH CENTRAL
U.S...STRETCHING EAST TO THE MID MS RIVER VALLEY. EAST OF THE RIDGE
CONVECTION CONTINUES TO DEVELOP ALONG ITS PERIPHERY AS A SERIES OF
VORTS CONTINUE TO TRACK SOUTHWARD ACROSS MUCH OF THE SE. LATEST
IR/WV LOOPS SHOW WEAKENING VORT MOVING OFF THE LA COAST WITH THE
NEXT IMPULSE MOVING SOUTHWARD ACROSS TN INTO N AL. WITH THIS BELIEVE
ANOTHER ROUND OF MOSTLY AFTERNOON AND EARLY EVENING CONVECTION WILL
BE LIKELY WITH THE BEST COVERAGE OCCURRING ACROSS THE SOUTHERN HALF
OF THE CWFA DUE TO BETTER MOISTURE CONVERGE FROM AFTERNOON SEABREEZE
EFFECTS. CURRENT RAOB AND MODEL SOUNDINGS SUGGEST A FEW STORMS COULD
BE STRONG TO SEVERE AS DRY AIR CONTINUES IN THE MID LEVELS...ALONG
WITH SLIGHTLY STEEPER LAPSE RATES OCCURRING WELL INLAND WHERE STORMS
WILL INITIALLY DEVELOP BEFORE MOVING SOUTHWARD TOWARDS THE COAST.
WILL STAY CLOSE TO CURRENT FORECAST TEMPS THOUGH DID NOTICE TEMPS
WERE SLIGHTLY WARMER YESTERDAY OVER MUCH OF THE WESTERN HALF OF THE
CWFA DUE TO INCREASED SUBSIDENCE FORM THE WEST.

.EXTENDED...STRONG UPPER RIDGE WILL RETROGRADE WEST AS DEEPENING
TROUGH DEVELOPS ACROSS MUCH OF THE EASTERN U.S. BY EARLY NEXT WEEK
TROF BECOMES WELL AMPLIFIED GIVING WAY TO INCREASED FORCING ALOFT AS
A SERIES OF VORTS TRACK EASTWARD ACROSS THE DEEP SOUTH. BASICALLY A
WETTER PATTERN LOOKS TO BE DEVELOPING FOR AT LEAST THE FIRST HALF OF
NEXT WEEK POSSIBLY GIVING WAY TO MORE MINOR FLOODING PROBLEMS DUE TO
SATURATED CONDITIONS ALREADY IN PLACE.

.MARINE...WILL CONTINUE WITH A LIGHT TO MODERATE WEST TO SOUTHWEST
FLOW THROUGH MUCH OF THE WEEKEND WITH SEAS AROUND 2 FEET. AS EASTERN
TROF DIGS LATE IN THE WEEKEND INTO NEXT WEEK PRESSURE GRADIENTS OVER
NORTH CENTRAL GULF WILL INCREASE AS TROF INTERACTS WITH BERMUDA LIKE
SFC HIGH OVER THE EAST AND NORTH CENTRAL GULF.

.FIRE...NO CONCERNS.
