AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
250 PM CDT SUN JUL 19 2015

.DISCUSSION...

LOW LEVEL MOISTURE AXIS...MOST LIKELY ENHANCED BY THE PREVIOUS
DAYS RAINFALL...WAS LOCATED NEAR THE I-59 CORRIDOR. AS WE REACHED
THE CONVECTIVE TEMPERATURE...MEAN MOISTURE VALUES AND K INDICES
WERE HIGH ENOUGH FOR THUNDERSTORM DEVELOPMENT. THE ACTIVITY WILL
USUALLY BE SOMEWHAT BRIEF AND MOVE/PROPAGATE SOUTHEAST THE
REMAINDER OF THE AFTERNOON. THIS ACTIVITY HAS INITIALLY DEVELOPED
IN A ZONE WHERE DRY AIR ALOFT IS LOCATED. SBCAPE VALUES OF
5000J...DOWNDRAFT CAPE AROUND 1000J AND A BIT MORE LOW LEVEL
MOISTURE CONVERGENCE WILL LEAD TO BETTER COVERAGE THIS
AFTERNOON...BUT IT SHOULD STILL DIMINISH QUICKLY AFTER SUNSET.
THE STORMS THAT DO DEVELOP MAY BECOME MARGINALLY SEVERE WITH GUSTY
WINDS AROUND 50 MPH...BRIEF HEAVY RAIN AND DEADLY LIGHTNING. ONCE
AGAIN...MEAN LAYER WINDS AND BULK SHEAR ARE LOW.

IT ALMOST SEEMS LIKE A BROKEN RECORD THESE DAYS AS THESE
DISCUSSIONS DON'T EVER TAKE ON A NEW FLAVOR. UNFORTUNATELY...NOT
ANY MORE CHANGES OR TRICKS IN THE CARDS THIS PACKAGE. MUGGY...
HOT AND HUMID CONDITIONS WILL HANG AROUND CENTRAL ALABAMA FOR
SEVERAL MORE DAYS. THE MODEL SUITE CONTINUES ITS GENERAL AGREEMENT
WITH THE SYNOPTIC EVOLUTION THROUGH THE PERIOD. LOW LEVEL
THICKNESSES REALLY DO NOT CHANGE MUCH THE ENTIRE WEEK...BUT THE
UPPER RIDGE DOES RETROGRADE WESTWARD. THIS WILL GRADUALLY INCREASE
POPS OVER CENTRAL ALABAMA AS A NORTHERLY COMPONENT AFFECTS US
AGAIN WITH TEMPS REMAINING WELL INTO THE 90S. CONFIDENCE ON THE
TEMPS AND DEW POINTS COMBINING FOR HEAT ADVISORY CRITERIA AS WELL
AS INCREASED RAIN CHANCES BEYOND MONDAY AND HAVE HELD THE
ADVISORY ONLY ONE MORE DAY AT THIS TIME. KEPT THE MENTION OF
THIS POTENTIAL HEAT EACH DAY THIS WEEK...BUT CONFIDENCE IS
REDUCED.

BY TUESDAY...THE UPPER DISTURBANCES START GETTING CLOSER OFF TO
THE NORTH AND RIDE THROUGH THE TENNESSEE VALLEY. BY WEDNESDAY
THROUGH FRIDAY...THE RIDGE RETROGRADES AND WILL PUT IS IN THE PATH
OF ANY SUBSEQUENT UPPER DISTURBANCES IN THE NORTHWEST FLOW. WILL
CONTINUE TO CLOSELY MONITOR THIS POTENTIAL ORGANIZED THUNDERSTORM
CHANCE AT PERIODS END.

&&

.AVIATION...
18Z TAF DISCUSSION.

VIGOROUS SHOWER AND THUNDERSTORM DEVELOPMENT IS ALREADY OCCURRING
AND WILL INCLUDE VCTS AT ALL SITES THROUGH THE AFTERNOON.
PREVAILING VFR CONDITIONS ARE EXPECTED THROUGH THE PERIOD BUT MAY
BE INTERRUPTED BY THUNDERSTORMS. WITH RELATIVELY DRY AIR ALOFT...
MICROBURST POTENTIAL IS HIGH AND WILL POSE A RISK TO AIRCRAFT.

87/GRANTHAM

.FIRE WEATHER...

CONTINUED HOT AND HUMID THROUGH THE WEEKEND WITH BELOW AVERAGE
RAIN CHANCES...ALTHOUGH A FEW ISOLATED THUNDERSTORMS WILL OCCUR.
NO FIRE WEATHER ISSUES ARE ANTICIPATED.
