.DISCUSSION...
/ISSUED 1050 AM CDT WED JUN 10 2015/
A WEAK CONVERGENCE BOUNDARY...REMNANTS OF THE FRONTAL BOUNDARY THAT
BROUGHT US RAIN AND SOME SEVERE WEATHER MONDAY NIGHT...CURRENTLY
EXTENDS FROM NORTH CENTRAL GEORGIA TO JEFFERSON COUNTY IN CENTRAL
ALABAMA. A WEAK LOW AT 850 MB CAN BE SEEN IN 12Z UPPER AIR ANALYSIS
OVER CENTRAL ALABAMA AS WELL. THIS IS CREATING CLOUDY CONDITIONS
OVER CENTRAL ALABAMA...WITH CLEAR SKIES AND SOME DISSIPATING PATCHY
MORNING FOG OVER NORTHERN ALABAMA.

EXPECT SCATTERED SHOWERS AND STORMS TO DEVELOP NEAR THIS WEAK 850 MB
LOW LATE THIS AFTERNOON AND EVENING. HOWEVER...FROM CULLMAN COUNTY
NORTHWARD ONLY EXPECT ISOLATED COVERAGE OF SHOWERS AND STORMS. A FEW
STRONGER STORMS WILL BE CAPABLE OF GUSTY WINDS TO 35 OR 40 MPH...BUT
WILL MAINLY PRODUCE HEAVY DOWNPOURS.

SCATTERED ACTIVITY...FROM THE WEAK 850 MB LOW...COULD MAKE IT INTO
CULLMAN COUNTY BY THIS EVENING...BUT THAT IS CURRENTLY OUTSIDE OF THE
UPDATE PERIOD.

TEMPERATURES AT 10 AM ARE ALREADY IN THE LOWER TO MID 80S WEST OF
INTERSTATE 65. SINCE EXPECTING MAINLY PARTLY CLOUDY SKIES...TEMPS
COULD CLIMB TO 90 TO 95 DEGREES IN MOST LOCATIONS. EXPECT HUNTSVILLE
AND MUSCLE SHOALS COULD CLIMB TO 95 OR 96 DEGREES. THIS IS REFLECTED
IN THE FORECAST GRIDS. OTHERWISE TWEAKED POPS...TO KEEP ISOLATED OUT
OF LAUDERDALE COUNTY AND LINCOLN/MOORE COUNTIES IN TENNESSEE.

KTW

&&

.AVIATION...
FOR 18Z TAFS...VFR CONDITIONS ARE EXPECTED THROUGH THE TAF PERIOD.
MODELS HINT AT SOME ISOLATED CONVECTION THIS EVENING UNTIL AROUND
11/06Z. HOWEVER...DUE TO LOW CONFIDENCE THIS ACTIVITY WILL DEVELOP
THAT FAR NORTH IN THE VICINITY OF THE TERMINALS...LEAVING IT OUT OF
TAFS FOR NOW. A SLIGHT REDUCTION IN VSBYS COULD OCCUR TONIGHT DUE TO
LIGHT WINDS...BUT EXPECT INCREASING CLOUDINESS TO CURTAIL THAT...SO
ONLY DROPPING VSBYS TO 6 SM AROUND DAYBREAK.
