.DISCUSSION...
/ISSUED 859 PM CDT WED OCT 1 2014/
ANOTHER PLEASANT EVENING IS UNDERWAY ACROSS THE TENNESSEE VALLEY WITH
AREA TEMPERATURES RANGING FROM 64F IN FORT PAYNE (4A9) TO A BALMY
75F STILL AT THE HUNTSVILLE AIRPORT (HSV). WHILE MOST OF THE FEW/SCT
CLOUDS THAT LINGERED ACROSS THE AREA LATE THIS AFTERNOON HAVE SINCE
DISSIPATED WITH SUNSET, A FEW ROGUE CLOUDS ARE APPROACHING NW AL AT
THIS HOUR (THE REMNANTS OF CONVECTION OVER THE MS RIVER/MEMPHIS AREA
A FEW HOURS AGO). THESE CLOUDS WILL CONTINUE TO DISSIPATE AS THEY
TRACK EASTWARD, WITH ONLY A FEW CLOUDS HERE/THERE OVERNIGHT TONIGHT.

THE POTENTIAL FOR PATCHY/DENSE FOG AGAIN TONIGHT WILL BE MUCH LESS IN
COVERAGE AS COMPARED TO LAST NIGHT, THANKS TO LIGHT WINDS EXPECTED
OVERNIGHT. I STILL WOULDN`T BE SURPRISED IF A FEW NOTORIOUSLY FOGGY
LOCATIONS (I.E. SHELTERED VALLEY LOCATIONS IN NE AL/SRN MIDDLE TN)
HAD REDUCED VSBYS TOMORROW MORNING AROUND SUNRISE, BUT GENERALLY,
ENOUGH MIXING IS EXPECTED OVERNIGHT AS THE SFC COLD FRONT TO OUR WEST
APPROACHES TO KEEP MUCH OF THIS DEVELOPMENT AT BAY.

THIS AFOREMENTIONED COLD FRONT IS CURRENTLY SPRAWLED SW TO NE ACROSS
THE CENTRAL PLAINS, ATTACHED TO A SFC LOW CENTERED IN ERN KS. IT`S
THIS FEATURE THAT WILL APPROACH THE AREA THROUGH THE DAY TOMORROW,
INCREASING CLOUDS AND THE CHANCES FOR SHOWERS/STORMS BY THIS TIME
TOMORROW.

FOR THE PUBLIC FORECAST UPDATE THIS EVENING: ONLY A FEW CHANGES WERE
NECESSARY. THESE CHANGES MAINLY CENTERED AROUND ADJUSTING HOURLY
TEMPS TO MATCH OBSERVATIONAL TRENDS ACROSS THE AREA, AS WELL AS TO
TWEAK SKY COVER TO FOLLOW IN LINE WITH SATELLITE TRENDS. OTHERWISE,
MORNING LOWS ARE ON TRACK TO FALL INTO THE UPPER 50S TO LOWER 60S. NO
ADDITIONAL CHANGES WERE NECESSARY.

UPDATED PRODUCTS WILL BE SENT SHORTLY.

.AVIATION...
FOR 06Z TAFS...
VFR CONDS ARE EXPECTED AT BOTH TAF SITES THROUGH AT LEAST MID-MORNING
TODAY, WITH A COLD FRONT APPROACHING THE AREA FROM THE WEST. LOW/MID
CLOUDS WILL INCREASE BY MIDDAY, WITH SHOWERS/STORMS DEVELOPING IN THE
VICINITY OF KMSL BY EARLY AFTERNOON (AND KHSV BY SUNSET). AS THE COLD
FRONT NEARS, A LINE OF TSTORMS WILL BEGIN IMPACTING KMSL BY/JUST
AFTER MIDNIGHT, SO MVFR CONDS WERE OFFICIALLY ADDED WITH THIS
ISSUANCE AFTER 03/05Z. THIS ACTIVITY WILL GRADUALLY SPREAD EASTWARD,
ARRIVING AT KHSV AFTER THE END OF THE TAF PERIOD.
