.DISCUSSION...

COLD FRONT IS CROSSING THE AREA THIS AFTERNOON...WITH A BROKEN LINE
OF SHOWERS CURRENTLY STRETCHING FROM BLOUNT COUNTY TO DALLAS COUNTY.
CANT RULE OUT AN ISOLATED THUNDERSTORM THIS AFTERNOON ACROSS THE
NORTHEAST. BIGGER PROBLEM IS THE GUSTY WINDS ASSOCIATED WITH THE
FRONT...EXPECT WIND GUSTS UP TO 40MPH JUST BEHIND THE LINE...AND
GUSTS UP TO 30MPH WELL INTO THIS EVENING AS COLD AIR FILTERS INTO
THE AREA UNDER NORTHWESTERLY FLOW. FRONT WILL BE EAST OF CENTRAL
ALABAMA BY SUNSET. MODEL GUIDANCE WANTS TO CLEAR SKIES OUT RATHER
QUICKLY THIS EVENING. HAVE LEANED MORE TOWARD CURRENT SATELLITE
TRENDS AND LEFT PARTLY TO MOSTLY CLOUDY SKIES IN FOR MUCH OF THE
AREA UNTIL LATE TONIGHT. THIS CLOUD COVER PLUS THE BREEZY WINDS
OVERNIGHT WILL KEEP TEMPERATURES FROM FALLING TO AROUND 30 DEGREES.
LOW TO MID 30S IN THE NORTH TO AROUND 40 DEGREES IN THE SOUTH IS
STILL EXPECTED. IF CLOUDS DO CLEAR...TEMPERATURES COULD BE SEVERAL
DEGREES COOLER...PUTTING NORTHERN SITES AT OR JUST BELOW FREEZING.
WILL MONITOR TEMP TRENDS THIS EVENING FOR POSSIBLE UPDATES.

A QUIET WEATHER PATTERN WILL SETUP ACROSS THE AREA FOR MUCH OF THE
WEEK. A LONGWAVE TROUGH WILL REMAIN ACROSS THE EASTERN CONUS WITH
RIDGING ACROSS THE WEST. SHORTWAVE ENERGY ROUNDING THE BASE OF THE
TROUGH WILL BECOME ELONGATED AND SKIRT THE AREA TO THE NORTH MONDAY
NIGHT. MOISTURE PROFILES WILL BE VERY SHALLOW...AND ALTHOUGH THERE
WILL BE DECENT LIFT NEARBY...DO NOT EXPECT ANY PRECIPITATION OTHER
THAN ISOLATED FLURRIES ACROSS THE FAR NORTH. CHANCES ARE NOT HIGH
ENOUGH TO MENTION IN THE FORECAST AT THIS TIME.  AN ELONGATED
SURFACE RIDGE WILL BUILD SLOWLY ACROSS THE EASTERN CONUS THROUGH THE
END OF THE WEEK. NORTHWESTERLY FLOW WILL CONTINUE TO REINFORCE THE
COOL AIR ACROSS CENTRAL ALABAMA...MAKING FOR SEVERAL MORNINGS WHERE
TEMPERATURES ARE EXPECTED TO DROP BELOW 32. LOCATIONS IN THE NORTH
AND WEST COULD SEE UPPER 20S MONDAY AND TUESDAY NIGHTS.

SEVERAL IMPULSES WITHIN NORTHWESTERLY FLOW WILL WORK THEIR WAY
TOWARD THE TENNESSEE VALLEY BY THE END OF THE WEEK. MODELS USUALLY
DO NOT HANDLE TIMING AND LOCATION OF THESE IMPULSES VERY
WELL...ESPECIALLY THIS FAR OUT. WILL CARRY SLIGHT POPS FOR A FEW
PERIODS NEXT WEEKEND...WITH A LEAN TOWARD THE DRIER ECMWF.
TEMPERATURES WILL MODERATE THROUGH THE END OF THE WEEK...WITH HIGHS
IN THE 60S BY THURSDAY AND OVERNIGHT LOWS IN THE 40S.

.AVIATION...
00Z TAF DISCUSSION

VFR CONDITIONS CURRENTLY ACROSS THE TERMINALS AND WILL CONTINUE
THROUGHOUT THE TAF CYCLE. THE MAIN IMPACT OVER THE NEXT 24 HRS
WILL BE THE STRONG WESTERLY WINDS. CURRENTLY THE COLD FRONT IS
MOVING TROUGH KTOI. WINDS HAVE BEEN GUSTING TO OVER 30 KTS IN A
FEW LOCATIONS OVER THE LAST COUPLE OF HOURS. WIND GUST WILL CONTINUE
UNTIL 05Z OR SO AND GUSTS SHOULD SUBSIDE BUT WINDS WILL REMAIN
ABOVE 12 KTS. AS MIXING OCCURS TOMORROW...WESTERLY WINDS WILL
BECOME GUSTY AGAIN AFTER 14Z WITH GUSTS OVER 30 KTS POSSIBLE. A
VFR CLOUD DECK WILL IMPACT THE NORTHERN TERMINALS DURING THE
OVERNIGHT HOURS WITH CEILINGS AROUND 4 KFT. A FEW MODELS ARE
TRYING TO SHOW MVFR CEILINGS ACROSS THE NORTH BUT WINDS SHOULD
KEEP CEILINGS VFR.
