NEAR TERM /NOW THROUGH THURSDAY/
 
SURFACE RIDGE OF HIGH PRESSURE  
CONTINUES ACROSS THE AREA, BUT THE RIDGE AXIS IF NOW JUST OFF TO  
THE EAST WITH A SOUTHEASTERLY RETURN FLOW SETTING UP ACROSS THE  
REGION. TEMPERATURES APPROACHING THE MIDDLE 70S OVER INTERIOR  
AREAS EARLY THIS AFTERNOON, AND NEAR 70 ALONG THE COAST. PATCHY  
FOG FROM EARLIER THIS MORNING, WHICH WAS MOST WIDESPREAD AROUND  
THE MOBILE BAY AREA, HAS DISSIPATED. NO FORECAST ADJUSTMENTS FOR  
THIS AFTERNOON ARE NECESSARY AT THIS TIME.  
 
NEARLY ZONAL FLOW ALOFT WILL PERSIST ACROSS THE REGION THROUGH  
THURSDAY. AT THE SURFACE, WINDS WILL SHIFT MORE TOWARD THE SOUTHWEST  
LATE TONIGHT AHEAD OF A WEAK COLD FRONT APPROACHING THE FORECAST  
AREA FROM THE NORTHWEST. THE FRONT WILL THEN ADVANCE FURTHER  
SOUTHWARD THURSDAY MORNING AND THEN STALL IN A WEST-EAST ORIENTED  
FASHION (HANGING UP IN THE NEAR ZONAL FLOW ALOFT) ABOUT HALFWAY  
THROUGH THE FORECAST AREA BY THURSDAY AFTERNOON. A COUPLE OF  
WEAK SHORTWAVE IMPULSES EMBEDDED WITHIN THE ZONAL FLOW PATTERN  
ALOFT WILL MOVE ACROSS OUR FORECAST AREA LATE TONIGHT INTO  
THURSDAY. WEAK ASCENT ASSOCIATED WITH THESE FEATURES AND WEAK  
MOISTURE RETURN POOLING UP ALONG THE STALLED FRONTAL BOUNDARY MAY  
AID IN THE DEVELOPMENT OF A FEW LIGHT RAIN SHOWERS ACROSS OUR  
NORTHWESTERN ZONES LATE TONIGHT AND INTO THURSDAY. WITH THE LOW  
LEVEL MOISTURE CONTINUING LATE TONIGHT INTO THURSDAY MORNING,  
THERE IS AGAIN A GOOD SIGNAL FOR FOG DEVELOPMENT IN THE MODELS AND  
CONDITIONS WOULD SUGGEST IT TO BE A LITTLE MORE PRONOUNCED OVER  
SOUTHERN AND EASTERN PORTIONS OF OUR FORECAST AREA DURING THAT  
TIME. WE HAVE MAINTAINED PATCHY FOG WORDING IN THE FORECAST FOR  
NOW, AND MAY HAVE TO CONSIDER POSSIBLE DENSE FOG ADVISORIES FOR AT  
LEAST PORTIONS OF THE SOUTHERN HALF OF THE FORECAST AREA FOR LATE  
TONIGHT INTO EARLY THURSDAY MORNING. MILDER TEMPERATURES WILL  
RETURN TONIGHT AHEAD OF THE FRONT, WITH LOWS RANGING IN THE 50S.  
TEMPERATURES ON THURSDAY WILL AGAIN BE WELL ABOVE SEASONAL NORMS,  
WITH HIGHS RANGING IN THE LOW TO MID 70S ACROSS THE REGION.  
THE RIP CURRENT RISK IS LOW THROUGH THURSDAY. /12  
 

 
   
AVIATION
 
 
24/18Z ISSUANCE...PATCHY FOG BURNED OFF EARLIER THIS MORNING AND

OVER THE SOUTHERN HALF OF THE FORECAST AREA. FOG MAY BE LOCALLY  
DENSE DOWN NEAR THE COAST. OTHERWISE, A LIGHT MAINLY SOUTHERLY  
FLOW THIS AFTERNOON AND EVENING, WITH CALM TO VERY LIGHT  
NORTHWESTERLY FLOW (MAINLY NEAR THE COAST) LATE TONIGHT AND EARLY  
THURSDAY MORNING. /12
