AREA FORECAST DISCUSSION...CORRECTED MARINE SECTION

350 AM EST THU JAN 26 2012

.SHORT TERM (TODAY-SATURDAY)...
MID/UPPER LEVEL CUTOFF LOW OVER TEXAS WILL MOVE INTO THE LOWER
MISSISSIPPI VALLEY TODAY AND OPEN UP AND PHASE WITH THE NEXT
NORTHERN STREAM SHORTWAVE AS IT MOVES INTO THE SOUTHEAST STATES
FRIDAY. AT THE SURFACE...HIGH PRESSURE OVER THE WESTERN ATLANTIC
WILL CONTINUE TO RIDGE WEST SOUTHWEST ACROSS FLORIDA TODAY WITH
THE COLD FRONT ASSOCIATED WITH THE MID/UPPER LEVEL LOW MOVING INTO
THE CENTRAL GULF. THIS FRONT WILL APPROACH THE REGION TONIGHT AND
MOVE ACROSS THE AREA DURING FRIDAY. HOWEVER...THE EXACT TIMING OF
THE FRONT AND ASSOCIATED PRECIPITATION CONTINUES TO VARY FROM
MODEL TO MODEL RUN...BUT THE LATEST MODELS HAVE COME IN LINE WITH
EACH OTHER. GUIDANCE IS NOW A LITTLE FASTER THAN PREVIOUS DAYS AND
BRINGS THE PRE-FRONTAL TROUGH AND ASSOCIATED SHOWERS AND
THUNDERSTORMS INTO THE COASTAL WATERS SHORTLY AFTER MIDNIGHT
TONIGHT AND INTO THE FLORIDA PENINSULA BY FRIDAY MORNING WITH MOST
OF THE CONVECTION EXITING THE SOUTHERN ZONES BY MID-AFTERNOON. THE
ACTUAL COLD FRONT WILL TRAIL THE PRE-FRONTAL TROUGH BY ABOUT SIX
HOURS AND MOVE ACROSS THE REGION DURING FRIDAY. POTENTIAL FOR A
FEW STRONG TO SEVERE STORMS CONTAINING STRONG/DAMAGING WINDS AND
AN ISOLATED WATERSPOUT/TORNADO STILL EXIST LATE TONIGHT INTO
FRIDAY MORNING WITH THE HIGHEST CHANCES ACROSS THE NORTHERN
COASTAL WATERS AND NATURE COAST WHERE THE BEST SHEAR AND
INSTABILITY WILL EXIST. HIGH PRESSURE WILL BUILD IN BEHIND THE
FRONT FRIDAY NIGHT AND SATURDAY WITH SOME COOLER DRIER AIR MOVING
INTO THE AREA. HOWEVER...IT LOOKS LIKE THE BOUNDARY WILL STALL
ACROSS SOUTH FLORIDA FRIDAY NIGHT AND THEN DRIFT NORTH SOME
SATURDAY AS THE NEXT SHORTWAVE MOVES THROUGH THE LONG WAVE TROUGH
OVER THE LOWER 48. THIS WILL CAUSE SOME CLOUDS AND POSSIBLY A
COUPLE OF SHOWERS TO MOVE BACK INTO THE SOUTHERN ZONES SATURDAY
AFTERNOON AND HAVE ADDED 20 POPS TO THIS AREA. TEMPERATURES WILL
REMAIN WELL ABOVE NORMAL TODAY AND TONIGHT THEN SLIGHTLY COOLER ON
FRIDAY THANKS TO THE CLOUDS AND RAIN...BUT STILL A FEW DEGREES
ABOVE NORMAL. TEMPERATURES WILL COOL TO BELOW NORMAL ACROSS THE
NORTH FRIDAY NIGHT AND REMAIN NEAR TO A FEW DEGREES ABOVE NORMAL
ACROSS THE CENTRAL AND SOUTH AS THE DRIER AIR MOVES IN AND THEN
CLIMB A FEW DEGREES ABOVE NORMAL ON SATURDAY.

.LONG TERM (SATURDAY NIGHT-WEDNESDAY)...
THE FRONTAL BOUNDARY LINGERS ACROSS SOUTH FLORIDA...BEYOND THE
CWA...AS UPPER LEVEL TROUGH FROM THE GREAT LAKES TO MEXICO WITH A
SURFACE HIGH OVER THE SOUTHERN PLAINS WORK EASTWARD...REACHING THE
EASTERN SEABOARD BY MONDAY NIGHT. THESE CONTINUE MOVING EAST...OUT
OVER THE ATLANTIC...TUESDAY AND WEDNESDAY WITH NEARLY ZONAL FLOW
OVER THE REGION WHILE THE SURFACE HIGH RIDGES BACK TO THE EASTERN
GULF.

EXPECT ANY PRECIPITATION WITH THE FRONT TO BE SOUTH OF THE AREA
AND WILL KEEP THE FORECAST DRY AT THIS TIME. AN INITIAL NORTHERLY
FLOW WILL INCREASE AS THE SURFACE HIGH TRACKS OVER THE GULF COAST
STATES WITH A TIGHTENING GRADIENT...AND VEERING WINDS TO THE
NORTHEAST AND THEN EAST AS THE HIGH MOVES BY TO THE NORTH. AS THE
HIGH SHIFTS OUT OVER THE ATLANTIC THE GRADIENT RELAXES WITH WINDS
BECOMING EAST AND SOUTHEAST. WIND SPEEDS WILL APPROACH CAUTION OR
ADVISORY LEVELS ON THE GULF FOR THE EARLY PART OF THE WEEK.
TEMPERATURES WILL BE JUST BELOW OR NEAR NORMAL SUNDAY THEN
GRADUALLY WARM WITH HIGHS IN THE UPPER 70S TO NEAR 80 BY
WEDNESDAY.

&&

.AVIATION...
ANTICIPATE ANOTHER NIGHT OF FOG...BUT SLIGHTLY HIGHER SOUTHEAST
WINDS WILL HELP LIMIT VISIBILITIES TO MAINLY MVFR WITH ONLY
ISOLATED IFR. WINDS VEER TO SOUTHERLY...AND GUSTY IN THE
AFTERNOON...AS THE FRONT APPROACHES WITH INCREASING MID AND HIGH
CLOUDS TONIGHT.

&&

.MARINE...
SOUTHERLY FLOW TODAY WILL BECOME SOUTHWEST TO WEST LATE TONIGHT AND
EARLY FRIDAY AND INCREASE AHEAD OF THE COLD FRONT THEN SHIFT TO
NORTHWEST TO NORTH BEHIND THE BOUNDARY DURING FRIDAY AND CONTINUE
THROUGH THE WEEKEND. WILL ISSUE A SMALL CRAFT ADVISORY FOR THE
NORTHERN AND CENTRAL OFFSHORE WATERS LATE THIS AFTERNOON AND TONIGHT
WITH EXERCISE CAUTION OVER THE NORTHERN AND CENTRAL NEAR SHORE
WATERS. WINDS WILL DIMINISH SOME FRIDAY NIGHT THROUGH SATURDAY NIGHT
THEN INCREASE EARLY NEXT WEEK AS THE GRADIENT TIGHTENS BETWEEN HIGH
PRESSURE TO THE NORTH AND THE STALLED OUT FRONT TO THE SOUTH.

&&

.FIRE WEATHER...
NO HIGHLIGHTS THROUGH SATURDAY AS RELATIVE HUMIDITY VALUES WILL
REMAIN ABOVE 35 PERCENT...THEN EARLY NEXT WEEK DRIER CONDITIONS
ARE EXPECTED.
