.DISCUSSION...

THE SURFACE FRONT THIS MORNING IS CLEAR DOWN TO THE COASTAL
WATERS...WITH DECENT NORTHERLY FLOW BEHIND IT. THERE STILL
REMAINS A SPREAD IN DEW POINTS ACROSS THE AREA AS DRIER AIR
ATTEMPTS TO FILTER INTO THE REGION. DUE TO THIS DIFFERENCE IN
MOISTURE. SOME AREAS GENERALLY ALONG AND SOUTH OF INTERSTATE 59
WILL SEE SOME PATCHY DENSE FOG THROUGH THE EARLY MORNING HOURS.
HOWEVER...MAY NOT HAVE AN ISSUE ACROSS PIKE/BARBOUR COUNTIES AS
THEY HAVE NOT CLEARED OUT YET WITH A PRETTY MUCH OVERCAST 9 KFT
CIGS. A COOL DAY MINUS THE RAIN FROM YESTERDAY WILL BE ON TAP WITH
HIGH PRESSURE OVER THE AREA.

EXPECTING ANOTHER SURFACE FRONT TO SINK ACROSS THE CENTRAL
U.S. TODAY OUT OF CANADA. THE ATMOSPHERE ACROSS ALABAMA WILL NOT
HAVE MUCH TIME TO RECOVER BETWEEN SYSTEMS AND ONLY MEAGER MOISTURE
WILL BE AVAILABLE. HOWEVER...ALTHOUGH SHALLOW...A FEW ISOLATED
SHOWERS WILL BE POSSIBLE ACROSS THE NORTH/EAST PART OF THE STATE
WITH THE PASSAGE DURING THE DAY FRIDAY. THE MAIN STORY WITH THE
FRONTAL PASSAGE WILL BE THE SIGNIFICANT 1030 PLUS RIDGE THAT WILL
SINK INTO THE CENTRAL PLAINS WITH TIGHT GRADIENTS AND NORTHERLY
FLOW ACROSS ALABAMA. ALTHOUGH THE MUCH COOLER CONDITIONS WILL
LIKELY BE AFTER TRICK OR TREAT TIME...TEMPERATURES WILL BE
DROPPING OFF NICELY AFTER SUNSET. NOT ONLY WILL IT GET COLDER
FRIDAY NIGHT ON THROUGH THE WEEKEND...IT WILL BE WINDY DURING THE
DAY SATURDAY. WHILE NOT WINDY ENOUGH FOR A WIND ADVISORY...WE WILL
SEE WIND CHILLS IN THE 20S FOR SATURDAY MORNING EARLY FOR THE
FIRST PART OF THE DAY. WILL DEFINITELY NEED THE JACKET/WIND
BREAKER ON SATURDAY. THE BETTER CHANCE FOR FROST WILL BE ON SUNDAY
MORNING AS THE RIDGE SHIFTS EASTWARD ACROSS THE EASTERN U.S. AND
LIGHTER GRADIENTS/WINDS ARE ANTICIPATED WITH CLEAR SKIES.

TEMPERATURES BEGIN TO MODERATE FOR THE END OF THE WEEKEND INTO THE
MONDAY/TUESDAY TIME FRAME AS THE RIDGE WEAKENS OVER ALABAMA
SHIFTING TOWARD THE ATLANTIC. BY THE LATER PART OF THE FORECAST...
RAIN CHANCES RETURN BY LATE TUESDAY INTO MID WEEK AS ANOTHER
FRONTAL SYSTEM PUSHES INTO THE STATE.

OTHER THAN A FEW MINOR GUSTS THIS AFTERNOON...NO AVIATION ISSUES
THROUGH THE NEXT 24 HOURS. THE FOG THAT FORMED NEAR ANB THIS
MORNING IS NOT EXPECTED TO REDEVELOP TONIGHT AS THE MOISTURE
CONTINUES TO DRY UP ACROSS THE AREA. WINDS WILL REMAIN NORTHERLY.
