SHORT TERM
 
 
A HEAT ADVISORY WILL BE ISSUED WITH THIS PACK TODAY. WINDS WILL  
BEGIN TO EASE TODAY CAUSING LESS VENTILATION OF THE COLUMN. THIS  
WILL HELP TEMPERATURES AND MOISTURE BECOME MORE COMPOUNDED TODAY  
AND MONDAY. CURRENTLY TEMPERATURES ARE IN THE UPPER 70S TO THE MID  
80S IN THE ADVISORY AREA AT 0330. GPT AND BOOTHVILLE ARE SHOWING  
85 THIS MORNING. CONCERNS FOR NOT REACHING FULL 108 TO 110 INDEX  
READINGS WILL BE CBRZ AND A FEW THUNDERSTORMS DEVELOPING. THIS  
SHOULD BEGIN TO OCCUR BETWEEN 2 AND 4PM TODAY. SO TIMING AND  
PLACEMENT OF ANY THUNDERSTORM ACTIVITY WILL KEEP TEMPS COOLER IN  
THOSE PLACES LUCKY ENOUGH TO GET THE CLOUD COVER OR THE RAIN. THE  
CBRZ WOULD ALSO HELP BY BRINGING SOME BREEZY CONDITIONS TO COOL  
TEMPS A BIT BUT IT MAY NOT PASS MOST LOCATIONS BEFORE MAX HEATING  
IS ACHIEVED.  
 
IT IS ALWAYS ADVISED DURING THE SUMMER TO CHECK AUTOMOBILES THAT  
ARE NOT RUNNING, ESPECIALLY ENCLOSED, FOR ANY PEOPLE OR ANIMALS.  
ESTIMATED TEMPERATURES CAN SOAR IN VEHICLES IN DIRECT SUNLIGHT TO  
120F WITHIN 15 MINUTES AND AS HIGH AS 140 WITHIN AN HOUR. THESE  
NUMBERS ARE ASSOCIATED WITH THE CONDITIONS THAT OUR AREA WILL  
EXPERIENCE TODAY AND POSSIBLY AGAIN ON MONDAY.  
 
FOR THOSE THAT GET THAT ISOLATED SHOWER OR TS, IT WILL BE A  
WELCOME RELIEF BUT FOR MOST, THE HEAT LOOKS TO STAY AROUND THROUGH  
AT LEAST THURSDAY. SOME DEEPER MOISTURE LOOKS TO MOVE INTO THE  
AREA POSSIBLY STARTING FRIDAY THROUGH THE WEEKEND. THIS WILL HELP  
BRING SOME CLOUDINESS AND SH/TS TO THE AREA BRINGING THE HIGH  
TEMPS DOWN TO SOMEWHAT MORE COMFORTABLE LEVELS. THE RAIN WILL BE  
WELCOMED BY THAT TIME AS WELL.  
 

 
   
AVIATION
 
 
EXPECT SOME MVFR CONDITIONS THIS MORNING BEFORE IMPROVING TO  
VFR CONDITIONS SHORTLY AFTER SUNRISE. THERE WILL BE A SLIGHT  
CHANCE OF SOME AFTERNOON CONVECTION ONCE THE SEABREEZE KICKS  
IN THIS AFTERNOON BUT THE CERTAINTY OF THE EXACT LOCATION OF  
SHOWERS OR STORMS IS NOT HIGH. HAVE NOT INCLUDED STORMS IN  
THE CURRENT TAFS THIS WILL HAVE TO BE WATCHED ESPECIALLY FOR  
THE 18Z TAFS. 13/MH  
   
MARINE
 
 
FAIRLY CLAM CONDITIONS ARE EXPECTED IN THE COASTAL WATERS  
THROUGH MOST OF THE WEEK AS HIGH PRESSURE BUILDS INTO THE  
AREA. THERE WILL BE A SLIGHT CHANCE EACH DAY FOR A STRAY SHOWER  
OR THUNDERSTORM BUT ORGANIZED CONVECTION IS LOW FOR THE BETTER PART  
OF THIS WEEK. 13/MH
