AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON KY
925 PM EDT THU MAY 25 2006

.DISCUSSION...

ANOTHER QUICK UPDATE TO THE ZONES TO ADJUST POPS AS LINE OF SHOWERS
AND THUNDERSTORMS HAS ENTERED THE BLUEGRASS COUNTIES. ALSO ADDED THE
SEVERE THUNDERSTORM WATCH. UPDATED ZONES ALREADY OUT.

&&

.PREV DISCUSSION...

706 PM EDT THU MAY 25 2006

JUST MADE A QUICK UPDATE TO UPDATE THE TIMING OF THE THUNDERSTORMS
AND ADD THE TORNADO WATCH TO THE FAR SOUTHWESTERN COUNTIES OF THE
CWA.

338 PM EDT THU MAY 25 2006

.SHORT TERM...(TONIGHT THROUGH FRIDAY)

FRONTAL BOUNDARY DRAPED FROM SOUTHEAST WI DOWN THROUGH
CENTRAL MO WILL DROP SOUTHEAST ACROSS THE AREA BY TOMORROW AFTERNOON.
TONGUE OF VERY JUICY AIR HAS SET UP OUT AHEAD OF THE FRONT...WITH
CONVECTION STARTING TO POP ALONG THIS TONGUE OF MOISTURE AS WELL AS
THE FRONT...AS A VIGOROUS SHORT WAVE CYCLES IN FROM WESTERN IL. SO
FAR VERY UNEVENTFUL ACROSS EASTERN KENTUCKY...WITH ONLY LOW TOPPED
FORMING AT BEST AS DEPARTING OVERNIGHT CONVECTION HAS LEFT US IN AN
AREA OF SUBSIDENCE.

EXPECT THIS TO ALL CHANGE LATER THIS EVENING AS A SQUALL LINE WILL
PUSH ONCE AGAIN TO THE SOUTHEAST. BIG DIFFERENCE COMPARED TO LAST
NIGHT WILL BE A MUCH MORE FAVORABLE LOW LEVEL AIR MASS OVER EASTERN
KENTUCKY. STORMS WILL NOT BE SO QUICK TO WEAKEN. DAMAGING WINDS WILL
BE THE MAIN THREAT WITH SOME LARGE HAIL A POSSIBILITY WITH ANY
PARTICULARLY DEEP CORES AS WET BULBS ARE NEAR 11K.

THIS ROUND OF PRECIPITATION WILL EXIT THE AREA AROUND DAWN...BEFORE
THE TROUGH AXIS AND COLD FRONT MOVE THROUGH...BRINGING ANOTHER ROUND
OF SHOWERS AND THUNDERSTORMS. SOME OF THESE STORMS COULD BECOME
SEVERE WITH GOOD INSTABILITY IN PLACE. LARGE HAIL AND DAMAGING WINDS
WILL BE THE MAIN THREAT.

LONG TERM...(FRIDAY NIGHT THROUGH THURSDAY)

LARGE SCALE RIDGING WILL TAKE PLACE ACROSS THE OH AND TN VALLEYS
BEGINNING FRIDAY NIGHT. ABOVE NORMAL TEMPERATURES WILL LAST
THROUGHOUT THE PERIOD...WITH DRY WEATHER PERSISTING THROUGH MONDAY
MORNING...BEFORE RIDGE BEGINS TO FLATTEN THROUGH THE REST OF THE
WORK WEEK AND MOISTURE GRADUALLY INCREASES. THINK THE LATEST GFS IS
A BIT TOO AGGRESSIVE WITH THE MOISTURE RETURN...SO HAVE CONTINUED
WITH DIURNALLY DRIVEN LOW CHANCE POPS FROM MONDAY THROUGH THURSDAY.

1137 AM EDT THU MAY 25 2006

14Z SFC ANALYSIS SHOWS A BOWLING BALL OF LOW PRESSURE ROLLING FROM
THE UPPER MIDWEST INTO THE GREAT LAKES. WITH THIS LOW...A COLD FRONT
EXTENDS FROM THE MIDDLE OF WISCONSIN TO JUST SOUTHEAST OF KANSAS
CITY. EARLIER CONVECTION FROM THE FIRST PART OF THE MORNING HAS MOVED
EAST OF KENTUCKY ATTM WITH ANOTHER BATCH WALLOPING CENTRAL TENNESSEE
..LIKELY TO STAY SOUTH OF OUR CWA. HOWEVER...MID AND HIGH LEVEL
CLOUDINESS FROM THESE STORMS ARE DRIFTING ACROSS EAST KENTUCKY AND
SHOULD HINDER ANY REDEVELOPMENT UNTIL LATE THIS AFTERNOON AT THE
EARLIEST AND PROBABLY NOT UNTIL MID EVENING AHEAD OF THE APPROACHING
COLD FRONT. THAT SAID...SHOULD SOMETHING POP EARLIER THEY WOULD HAVE
LITTLE TROUBLE BECOMING STRONG TO SEVERE WITH LIS TO -8 AND CAPE TO
3000 J/KG...THOUGH WEAK HELICITY WOULD TEND TO FAVOR PULSE TYPE
STORMS. AS SUCH...WILL TAKE DOWN POPS SIGNIFICANTLY FOR THE AFTERNOON
AND ALSO FINE TUNE SKY COVER...TEMPS AND DEWPOINTS. UPDATE TO THE
GRIDS AND TEXT PRODUCTS WILL BE ISSUED SHORTLY.

524 AM EDT THU MAY 25 2006

REMNANTS OF A LARGE MCS COMPLEX TRYING TO PUSH ACROSS ERN KY BUT IS
RUNNING OUT OF STEAM AS IT ENCOUNTERS THE MUCH DRIER AIR AND A
DOWNSLOPING SE WIND. STILL IT SHOULD MOISTEN THE AIR IN PREPARATION
FOR THE WARM FNT TO ENTER THE PICTURE THIS AFTERNOON. BETWEEN THE
DYING PCPN AND THE WARM FNT...THE SKY SHOULD BRIEFLY CLEAR ENUF TO
ALLOW TEMPS TO CLIMB INTO THE LOWER 80S AND PRODUCE SUFFICIENT LIFT
TO FORM TSRA THIS AFTERNOON WITH THE WARM FNT PROVIDING THE EXTRA
LIFT AND ADDITIONAL ADVECTION OF LLVL MOISTURE. WITH THE CURRENT
LACK OF AVAILABLE LLVL MOISTURE THE GREATEST RISK FOR SVR WX SHOULD
REMAIN WEST OF THE CWFA. HOWEVER CANNOT RULE OUT ISOLATED CELLS.

LOW PRESS IN THE WRN GT LKS WILL MOVE EAST AND DRAG A COLD FNT THRU
THE AREA ON FRI FOR ANOTHER ROUND OF TSRA. WITH THE RESIDUAL
MOISTURE AND A DECENT LLVL JET WE STAND A BETTER CHC FOR SEVERE WX.
RIDGE REASSERTS ITSELF RAPIDLY FRI NITE WITH THE HOLIDAY WEEKEND
FCST TO BE RAIN FREE BUT TEMPS WILL CLIMB INTO THE 80S WITH SOME
AREAS INTO THE UPPER 80S. BY EARLY NEXT WEEK THE UPPER LVL PATTERN
BECOMES MORE ZONAL WITH THE STORM TRACK TO REMAIN ACROSS THE NRN GT
LKS. THIS WILL PUT ER KY INTO A MORE SUMMERLIKE CONVECTIVE PATTERN
WITH A DIURNAL FLAIR TO THE PCPN EACH AFTERNOON INTO THE EVENING
WHILE THE OVERNIGHT INTO MORNING PD SHOULD BE CALM WITH LITTLE WX
OTHER THAN SOME FOG.
