AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE JACKSON KY
1047 AM EDT THU AUG 9 2012

.UPDATE...
ISSUED AT 1045 AM EDT THU AUG 9 2012

SHOWERS AND THUNDERSTORMS ARE MOVING INTO THE SWRN COUNTIES OF OUR
CWFA. CURRENTLY ONLY ISOLATED BUT SOME OF THEM COULD BECOME QUITE
STRONG. CURRENT POPS ARE GOOD AND WITH THE CLOUD CLVER THE TEMPS ARE
GOOD AS WELL. HAVE UPDATED GRIDS WITH LATEST ESTF DAT UPLOAD BUT
ZONES ARE IN GOOD SHAPE. ONE FEATURE TO WATCH IS A STRONG OUTFLOW
FROM THE MCS IN OHIO THAT IS PUSHING THRU OUR NERN COUNTIES. THIS
FEATURE MAY SPARK ADDITIONAL STORMS WITH THE DAY TIME HEATING.

UPDATE ISSUED AT 757 AM EDT THU AUG 9 2012

UPDATED THE FORECAST TO BETTER REFLECT CURRENT CONDITIONS AND MODEL
TRENDS. THE ONLY CHANGE WAS TO INCREASE THE CLOUDS FOR TODAY.

&&

.SHORT TERM...(TODAY THROUGH FRIDAY)
ISSUED AT 254 AM EDT THU AUG 9 2012

THE MODELS ARE IN GOOD GENERAL AGREEMENT SHOWING A SHORT WAVE MOVING
TOWARD THE AREA FROM THE NORTHWEST TODAY. THE SHORT WAVE WILL PUSH A
COLD FRONT TOWARDS THE AREA. THE INITIAL SHORT WAVE WILL BE A WEAK ONE
AND BEFORE THE FRONT CAN MOVE INTO THE AREA...A STRONG SHORT WAVE
ASSOCIATED WITH THE UPPER LOW DROPPING DOWN ACROSS WISCONSIN TONIGHT
WILL PRODUCE A WAVE ON THE FRONT AND KEPT IT NORTH OF THE AREA AND
KEEP THE FRONT FROM ACTUALLY MOVING ACROSS THE AREA UNTIL FRIDAY
DURING THE DAY. THE MOST IMPORTANT FORECAST ISSUE FOR TODAY IS THE
SEVERE WEATHER POTENTIAL. SPC HAS PUT MOST OF EASTERN KENTUCKY IN A
SLIGHT RISK (15 PERCENT) FOR SEVERE THUNDERSTORMS TODAY. THE NAM BUFR
SOUNDING FOR THIS AFTERNOON IS SHOWING VERY UNSTABLE AIR OVER THE
AREA WITH LIFTED INDEX VALUES OF -8 AND TOTAL TOTALS OF 53 OVER THE
AREA AT 4 PM. THE POTENTIAL ENERGY...AS MEASURED BY THE CAPE...IS
AROUND 2000. THERE IS SOME DECENT TURNING OF THE WINDS FROM 5-20K FT
WHICH WILL BE CONDUCIVE FOR LARGE HAIL FORMATION. THE FREEZING LEVEL
IS ALSO A BIT LOWER THAN IT WAS THE LAST COUPLE OF WEEKS. AT 2
PM...THE NAM BUFR IS SHOWING SOME DRY AIR ALOFT WHICH WOULD BE
CONDUCIVE FOR STRONG WIND GUSTS...HOWEVER BY 4 PM...SOME MID LEVEL
MOISTURE WILL BE MOVING INTO THE AREA. THE SINGLE MISSING ELEMENT IS
THE FORCING WHICH IS NEEDED TO INITIATE THE CONVECTION. DUE TO THE
WEAK FORCING...HAVE ONLY FORECAST SCATTERED ACTIVITY THIS AFTERNOON
AND THEN UPPED THINGS TO LIKELY THIS EVENING AS THE FRONT GETS CLOSER TO
THE AREA. A COMBINATION OF THE STORM MOTION OF 10-15 MPH AND
PRECIPITABLE WATER VALUES OF 1.25 TO 1.5 INCHES THIS AFTERNOON SHOULD
HELP LIMIT ANY HEAVY PRECIPITATION AMOUNTS. THE ONLY FLASH FLOODING
POTENTIAL SHOULD BE LIMITED ONLY TO A RARE CASE WHERE STORMS TRAIN
ACROSS THE SAME AREA. ON FRIDAY THE PRECIPITABLE WATER
INCREASES...HOWEVER THE STORM MOTION ALSO PICKS UP TO 20-30 MPH.
TEMPERATURES WERE ONLY TWEAKED A LITTLE TO BETTER REFLECT MODEL
TRENDS.

.LONG TERM...(FRIDAY NIGHT THROUGH WEDNESDAY)
ISSUED AT 323 AM EDT THU AUG 9 2012

THE MODELS REMAIN IN GOOD AGREEMENT WITH A PROGRESSIVE TREND TO THE
EXITING UPPER LEVEL LOW THROUGH THE FIRST PART OF THE WEEKEND...WITH
SCATTERED SHOWERS AND AN ISOLATED THUNDERSTORM OR TWO ENDING IN THE
EVENING ACROSS EASTERN KENTUCKY. MUCH MORE COMFORTABLE AIR WILL
ARRIVE BEHIND THIS SYSTEM...WITH SATURDAY HIGHS PEAKING IN THE MIDDLE
TO UPPER 70S WITH DEW POINTS DOWN INTO THE LOWER AND MIDDLE 50S.

GENERALLY DRY WEATHER WILL HOLD ON THROUGH THE MIDDLE OF NEXT
WEEK...WITH SLOWLY MODIFYING TEMPERATURES...REACHING SLIGHTLY ABOVE
NORMAL VALUES BY WEDNESDAY. ONE POTENTIAL FLY IN THE OINTMENT WILL BE
A PASSING SHORT WAVE TROUGH FROM MONDAY NIGHT THROUGH TUESDAY. THE
ECMWF HAD BEEN MUCH WEAKER AND DECISIVELY DRY WITH THIS
FEATURE...WHILE THE GFS HAS BEEN PLAYING THIS UP IN MORE RECENT RUNS.
THE LATEST 00Z ECMWF HAS COME IN A BIT MORE LIKE THE GFS...SO SOME
LOW CHANCE POPS MAY BE NEEDED IF THIS TREND HOLDS.

&&

.AVIATION...(FOR THE 12Z TAFS THROUGH 12Z FRIDAY MORNING)
ISSUED AT 757 AM EDT THU AUG 9 2012

FOG WILL BE BURNING OFF BETWEEN 8 AND 9 AM THIS MORNING. SOME OF THE
RIVER VALLEYS HAD SOME VLIFR FOG THIS MORNING HOWEVER ONLY LONDON HAD
SOME MVFR. THE REST OF THE TAF STATIONS WERE MVFR. EXPECTING SOME
SCATTERED THUNDERSTORMS TO FORM THIS AFTERNOON...HOWEVER F CONFIDENCE
IN THE LOCATIONS AND TIMING OF STORMS IS LOW. WILL HAVE A BETTER IDEA
THIS AFTERNOON TO SEE WHERE THE CONVECTION WILL FORM. IF
THUNDERSTORMS DO FORM...CIGS SHOULD STAY VFR...HOWEVER SOME TEMPO IFR
VSBY WILL BE POSSIBLE NEAR THE STRONGEST STORMS. LARGE HAIL AND
DAMAGING WINDS ARE ALSO POSSIBLE TODAY NEAR THE STRONGEST STORMS.
EXPECT WIDESPREAD RAIN TO START AFTER 6Z.
