AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOBILE AL
ISSUED BY NATIONAL WEATHER SERVICE TALLAHASSEE FL
1020 AM CDT TUE JUL 10 2012

.SYNOPSIS...
13 UTC SURFACE ANALYSIS SHOWS A FRONTAL BOUNDARY ACROSS THE MID
SOUTH AND INTO THE CAROLINA PIEDMONT. SOUTHERLY WINDS SOUTH OF THIS
BOUNDARY AROUND A HIGH PRESSURE AREA NEAR THE FLORIDA PENINSULA IS
INCREASING LOW LEVEL MOISTURE SIGNIFICANTLY THIS MORNING.
OBSERVATIONS SHOW A POOL OF 75 PLUS DEGREE DEWPOINTS NOT FAR OFF THE
ALABAMA COASTLINE.

UPPER AIR DATA FROM 12 UTC CONTINUES TO SHOW THE PERSISTENT WEAK
UPPER LOW CENTERED ABOUT NEAR JACKSON MS. THIS DISTURBANCE WILL
COMBINE WITH A LARGE DEEP LAYER MOISTURE PLUME TO GENERATE SCATTERED
TO NUMEROUS SHOWERS AND THUNDERSTORMS ACROSS THE REGION.

.NEAR TERM...
THIS UPPER LEVEL LOW MOVING EASTWARD FROM LOUISIANA INTO ALABAMA. AS
A RESULT...NEW ORLEANS IS ALREADY EXPERIENCING SHOWERS ACROSS THEIR
ENTIRE REGION. THIS WILL SPREAD SHOWERS AND THUNDERSTORMS INTO IN
OUR REGION LATER TODAY WITH GUSTY WINDS AND POTENTIALLY SMALL HAIL.
THE TEMPERATURES TODAY WILL BE IN THE HIGH 80S TO MID 90S ALL ACROSS
OUR AREA.

VISIBLE SATELLITE AND RADAR DATA SHOW THE CONVECTIVE CLUSTER OF
STORMS JUST NORTH OF NEW ORLEANS MOVING NORTHEAST ACROSS LAKE
PONTCHARTRAIN TOWARD SOUTHEASTERN MISSISSIPPI. THE CONVECTIVE
OUTFLOW FROM THESE STORMS WILL ONLY SERVE TO PROVIDE ENHANCED
CONVERGENCE AND LEAD TO ADDITIONAL STORM DEVELOPMENT LATER THIS
MORNING AND ESPECIALLY THIS AFTERNOON AS THE BOUNDARY MOVES INTO A
PROGRESSIVELY MORE UNSTABLE AIRMASS ACROSS SOUTHEASTERN MISS AND
INTO SOUTHWESTERN ALABAMA. MODIFIED 12 UTC SOUNDING DATA CONFIRMS
THE POTENTIAL FOR MODERATE TO SIGNIFICANT INSTABILITY THIS AFTERNOON
WITH SBCAPES LIKELY IN THE 2500 J/KG TO 3000 J/KG RANGE. THIS IS WHY
THE CURRENT THINKING IS FOR SMALL HAIL AND GUSTY WINDS THIS
AFTERNOON...SO ADDED THIS INTO THE ONGOING FORECASTS. ALSO INCREASED
RAIN CHANCES INTO THE LIKELY CATEGORY...AROUND 60 PERCENT...AND THIS
MAY NEED TO BE UPDATED LATER THIS AFTERNOON SHOULD CONVECTIVE TRENDS
SUPPORT MORE STORM ORGANIZATION.

&&

.AVIATION...SCATTERED TO NUMEROUS THUNDERSTORMS WILL CONTINUE TO
DEVELOP LATE THIS MORNING AND COULD AFFECT THE TAF SITES WITH SOME
BRIEF IFR OR MVFR AND GUSTY WINDS...PARTICULARLY MOB AND BFM. CHANCE
FOR STORMS IN THE AFTERNOON SEEMS TO BE HIGHER AT PNS...AS EARLIER
ACTIVITY AROUND MOBILE WILL LIKELY STABILIZE THE ATMOSPHERE A BIT.
FOR AIRCRAFT FLYING IN OR OUT OF ANY OF THE THREE TERMINALS...EXPECT
SCT-NUM TSRA AROUND MUCH OF THE REGION THROUGH SUNSET. ANY STORMS
SHOULD START TO DIMINISH IN THE EVENING HOURS.

&&

.MARINE...LITTLE CHANGE THIS MORNING TO THE COASTAL WATERS FORECAST
ASIDE FROM ADDING MENTION OF WATERSPOUTS THIS MORNING NEAR THE COAST
AND INTO MOBILE BAY. WINDS AND SEAS WILL REMAIN GENERALLY LOW
OUTSIDE THE SEA BREEZE ZONE. LOCALIZED INCREASES IN WINDS AND SEAS
ARE EXPECTED IN AND NEAR STRONG SHOWERS AND THUNDERSTORMS TODAY.
