.DISCUSSION...

A FEW SHOWERS AND THUNDERSTORMS WERE LOCATED ACROSS NORTH ALABAMA ALONG
A PRE-FRONTAL OUTFLOW BOUNDARY. THE REAL COLD FRONT WAS MARKED BY A
NICE DROP IN DEWPOINT TEMPERATURES. THE ACTUAL FRONT HAS MOVED THROUGH
MEMPHIS AND NASHVILLE WHERE DEWPOINTS WERE 61 AND 49 RESPECTIVELY.
DEWPOINT AT TUPELO WAS STILL A MUGGY 71 DEGREES. THE CONVECTION
WAS MOVING FAIRLY QUICKLY TO THE SOUTHEAST AND EXPECT THE RAIN TO
BE MOSTLY SOUTH OF I-20 BY MIDNIGHT. NORTH WINDS OVERNIGHT WILL
LIKELY KEEP TEMPERATURES UP A LITTLE AND RAISED OVERNIGHT LOWS A
FEW DEGREES MOST AREAS.

.AVIATION...
06Z TAF DISCUSSION.

SHOWERS AND STORMS HAVE DEVELOPED AS EXPECTED OUT AHEAD OF THE
COLD FRONT THAT HAS MOVED INTO NORTHERN ALABAMA LATE THIS EVENING.
MOST OF THE CONVECTION HAS REMAINED SCATTERED IN NATURE...AND
LIGHTNING OUTPUT HAS DIMINISHED GREATLY OVER THE PAST FEW HOURS.
FOR THE NORTHERN SITES THROUGH 07Z...EXPECT VICINITY SHOWERS OR A
THUNDERSTORM WITH THE PASSAGE OF THE COLD FRONT. BROKEN CIGS FROM
3 TO 5 THOUSAND FEET WILL BE EXPECTED THROUGH THE MORNING HOURS
ON MONDAY THEN CLEARING THROUGH THE AFTERNOON. FOR THE SOUTHERN
SITES...HAVE NOT INCLUDED ANY MENTION OF SHOWERS OR STORMS AT THIS
TIME DUE TO LOW CONFIDENCE OF CONVECTION REACHING KMGM OR KTOI.
SKIES SHOULD CLEAR THE SOUTHERN SITES BY THE LATE AFTERNOON AND
EVENING HOURS.

PREVAILING WINDS AT THE SURFACE WILL SHIFT TO THE NORTH OVERNIGHT
TONIGHT AND BECOME GUSTY BEHIND THE INITIAL COLD FRONTAL PASSAGE.
DURING THE DAY ON MONDAY...NORTH WINDS AROUND 10-12 KNOTS WILL
PREVAIL WITH SOME HIGHER GUSTS POSSIBLE. WINDS WILL DIMINISH AFTER
SUNSET.

NOTE...THE NATIONAL WEATHER SERVICE WILL BEGIN ISSUING SEASONAL
TERMINAL FORECASTS FOR THE TALLADEGA MUNICIPAL AIRPORT (KASN) IN
TALLADEGA...ALABAMA. THE FORECAST WILL BEGIN OCTOBER 5TH AT 00Z
AND LAST THROUGH AT LEAST THE 23RD OF OCTOBER.
