.DISCUSSION...

UPPER LEVEL TROUGHING STILL IN PLACE ACROSS THE EASTERN CONUS
WITH RIDGING ACROSS THE DESERT SOUTHWEST. AT THE SFC NORTHERLY
FLOW CONTINUES ACROSS ALABAMA WITH HIGH PRESSURE TO THE NORTH OVER
THE GREAT LAKES REGION. SKIES ARE CLEAR AND TEMPS HAVE FALLEN INTO
THE LOW/MID 60S IN MOST LOCATIONS...WITH A FEW UPPER 50S BEING
REPORTED IN THE FAR NORTH. TEMPS WILL DROP A COUPLE MORE DEGREES
BY SUNRISE. DRY CONDITIONS WILL CONTINUE TODAY WITH TEMPS A COUPLE
DEGREES WARMER THAN YESTERDAY.

SFC WINDS WILL BECOME EASTERLY ON FRIDAY AS THE RIDGE TRANSLATES
EASTWARD TOWARD THE ATLANTIC COAST. MEANWHILE...IN THE UPPER
LEVELS AN EASTERLY WAVE WILL CROSS FLORIDA AND A CUTOFF LOW IS
STILL PROGGED TO DEVELOP ACROSS THE NORTHERN GULF. MOISTURE VALUES
STILL APPEAR TOO LOW ON FRIDAY TO SUPPORT MUCH PRECIP ACROSS
CENTRAL ALABAMA BUT MOISTURE VALUES INCREASE BY SATURDAY WITH PW
VALUES BACK NEAR 1.5 INCHES. WITH DECENT MOISTURE AND LIFT FROM
THE UPPER LOW SCATTERED CONVECTION APPEARS LIKELY OVER THE
WEEKEND.

THE UPPER LOW EJECTS NORTHEAST INTO THE OHIO VALLEY ON MONDAY AS A
SHORTWAVE DIVES SOUTHWARD ACROSS THE MIDWEST. MEANWHILE MODELS
BRING WHAT IS CURRENTLY TS ERIKA NORTHWARD ALONG THE EAST COAST OF
FLORIDA. CURRENT GUIDANCE WOULD KEEP ERIKA FAR ENOUGH TO OUR EAST
AND WOULD HAVE VERY MINIMAL IMPACTS FOR CENTRAL ALABAMA...BUT
UNCERTAINTIES IN THE TRACK STILL REMAIN. FOR NOW WILL CARRY 20-30
POPS IN THE EXTENDED. TEMPS WILL GENERALLY BE NEAR CLIMATOLOGICAL
NORMS.
