AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOUISVILLE KY
258 PM EDT SAT OCT 1 2011
.SHORT TERM (TONIGHT AND SUNDAY)...
...FROST TONIGHT...
UPPER LEVEL LOW VERY EVIDENT ON WATER VAPOR OVER VA CONTINUES TO
STREAM BROKEN STRATO-CU SKIES ON THE BACK SIDE OF IT ACROSS OUR
EASTERN HALF OF THE CWA. BECAUSE OF THIS...SOME LOCATIONS ACROSS SE
INDIANA AND OUR BLUEGRASS COUNTIES OF KY HAVE NOT REACHED 50 DEGREES
YET. A SMALL BREAK IN THE CLOUDS THOUGH OVER THE NEXT COUPLE OF
HOURS WOULD CHANGE THAT. THESE CLOUDS KEEPING TEMPS DOWN TODAY WILL
ALLOW A HEAD/S START AT A COOL DOWN TONIGHT. MOST CLOUDS ALONG AND
WEST OF A LINE FROM MADISON IN TO BURKESVILLE KY SHOULD WANE BY
SUNSET TONIGHT. SOME CLOUDS WILL STICK AROUND OVER THE BLUEGRASS BUT
AS THE UPPER LOW MOVES EASTWARD...CLOUDS SHOULD MOVE EAST WITH IT.
LOW-LEVEL MOISTURE FIELDS FROM THE NAM AND GFS CLEAR OUT LEXINGTON
BY 06-07Z.
SO WITH CLEARING SKIES OVERNIGHT AND RELAXING WINDS...AT LEAST
PATCHY FROST IS EXPECTED TO DEVELOP OVERNIGHT. THE ONLY THING THAT
MAY KEEP WIDESPREAD FROST FROM OCCURRING WILL BE THE WINDS.
NORTH-NORTHWEST WINDS OF 4-6MPH SHOULD OCCUR IN MANY SPOTS WHICH
WILL BE ENOUGH OF A WIND TO HELP PRECLUDE FROST FORMATION. HOWEVER
AREAS OF FROST MAY OCCUR NEAREST THE APPROACHING SFC HIGH PRESSURE
THAT IS NOW OVER NRN IL...OR OVER THE BLUEGRASS REGION OF KY WHERE
TEMPS ARE LOWER THAN EVERYWHERE ELSE/AND MORE SHELTERED LOCATIONS
EXIST. IT MAY BE A BORDERLINE EVENT...BUT WILL ISSUE A FROST
ADVISORY OVER OUR NRN TIER OF INDIANA COUNTIES AS WELL AS FROM
TRIMBLE...HENRY AND FRANKLIN COUNTIES ON DOWN TO CUMBERLAND AND
EASTWARD TOWARDS DAWN TOMORROW. OVERNIGHT LOWS IN THE MID TO UPPER
30S WILL BE THE RULE.
TOMORROW SHOULD BE NEARLY A REPEAT OF TODAY...ONLY SLIGHTLY WARMER
AND WITH LESS CLOUDINESS AROUND. HAVE MID/UPPER 60S WEST TO AROUND
60 EAST FOR HIGHS SUNDAY UNDER MOSTLY SUNNY SKIES. MORE STRATO-CU
MAY DEVELOP AROUND THE LEX METRO AREA AGAIN AS ANOTHER LOBE OF
ENERGY ROTATES AROUND THE EAST COAST UPPER LOW. SIMILAR TO TODAY AS
WELL...WE WILL SEE GUSTY NORTHWEST WINDS FROM LATE MORNING THROUGH
THE AFTERNOON HOURS ON SUNDAY. MOST GUSTY WINDS WILL OCCUR EAST OF
I-65.
.LONG TERM (SUNDAY - FRIDAY)...
DRY PATTERN LOOKS TO STAY IN FOR THE LONG TERM PERIOD WITH A WARMUP
IN STORE...SHOULD BE PLEASANT FALL WEATHER. SUNDAY NIGHT A LARGE
UPPER LOW WILL BE SPINNING AROUND WV/NORTHERN VA...WITH OUR REGION
ON THE DRY SIDE. SURFACE HIGH PRESSURE WILL BE HELD AT BAY TO OUR
WEST...KEEPING A WEAKER BUT STEADY NORTHERLY WIND ACROSS THE AREA.
ONCE AGAIN THE EAST WILL HAVE THE BEST CHANCE AT KEEPING CLOUDS
IN...BECAUSE OF IT/S PROXIMITY TO THE LOW.
BY TUESDAY...THE INFLUENCE OF THAT UPPER LOW SHOULD START FADING
AWAY AS IT HEADS OFF TO THE MID ATLANTIC COAST. THICKNESSES WILL
INCREASE AS RIDGING BUILDS IN BEHIND THE LOW. THE REST OF THE
FORECAST LOOKS STRAIGHTFORWARD. AS THIS RIDGING BUILDS IN A SURFACE
RIDGE WILL DOMINATE THE NORTHEAST U.S. WILL SEE TEMPERATURES RISE TO
THE UPPER 70S/AROUND 80 BY THE SECOND HALF OF THE WORK WEEK.
DGEX HINTING AT SOME RAIN CHANCES IMMEDIATELY WEST OF THE REGION
JUST AFTER THIS FORECAST PERIOD...BUT GFS AND 00Z ECMWF KEEP THE
OHIO VALLEY DRY FOR A FEW MORE DAYS BEYOND IT.
&&
.AVIATION (18Z TAF ISSUANCE)...
UPPER LEVEL LOW CONTINUES TO FILTER IN BKN-OVC MVFR CIGS INTO THE
LEX TERMINAL. SKIES THERE SHOULD BECOME MORE BKN THAN OVC...BUT WILL
HOVER AROUND THE MVFR/VFR THRESHOLD. SDF SKIES SHOULD RANGE FROM
SCT-BKN AROUND 3KFT...AND BWG SHOULD STAY SCATTERED AROUND THE SAME
HEIGHT FOR THE REST OF TODAY. GUSTY NNW WILL CONTINUE AS WELL...WITH
SUSTAINED WINDS FROM 8-13 KNOTS AND GUSTS UP TO AND AROUND 20 KNOTS.
TONIGHT...SKIES WILL CLEAR AT BWG AND SDF MOST LIKELY BY
00Z...PERHAPS BY 06Z AT LEX (OR AT LEAST DROP BACK TO FEW-SCT). NO
VSBY RESTRICTIONS EXPECTED TONIGHT AS ANY LOW-LEVEL MOISTURE WOULD
BECOME FROST...NOT FOG.
FOR SUNDAY...SKIES WILL BE MOSTLY SUNNY FOR BWG AND SDF...PERHAPS
SOME SCT LATE MORNING STRATO-CU DEVELOPING AGAIN FOR LEX AND
POSSIBLY AS FAR WEST AS SDF. GUSTY NNW WINDS WILL AGAIN OCCUR BUT
MOSTLY AT LEX.
