Damaging Wind in Kentucky, June 20, 2006

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE JACKSON KY
1015 AM EDT TUE JUN 20 2006

.DISCUSSION...

13Z SFC ANALYSIS SHOWS WEAK HIGH PRESSURE THROUGH EAST KENTUCKY WITH
A DEVELOPING WARM FRONT JUST TO THE NORTHWEST OF THE CWA. ON
RADAR...A FEW ROGUE THUNDERSTORMS HAVE POPPED UP ON OUR FRINGES
DURING THE PAST COUPLE OF HOURS. THE STRONGEST IS SLIPPING PAST TO
THE EAST OF PIKE COUNTY...HOWEVER ITS OUTFLOW APPEARS TO BE ENOUGH TO
INITIATE ADDITIONAL CONVECTION TO THE WEST. THE CURRENT FORECAST IS
IN GOOD SHAPE WITH RESPECT TO TEMPERATURES AND SKY COVER. WILL UPDATE
TO ALLOW A SLIGHT CHANCE OF A SHOWER OR THUNDERSTORM DURING THE REST
OF THE DAY...ESPECIALLY GIVEN THE CURRENT SCOPE. THE THREAT SHOULD
BE DIMINISHING THIS AFTERNOON...THOUGH...AS THE COLUMN DRIES OUT AND
A MID LEVEL CAP DEVELOPS. ALTHOUGH...WITH THE OUTFLOW BOUNDARIES
AROUND AND DEWPOINTS IN THE MID AND UPPER 60S WOULD NOT WANT TO GO
COMPLETELY DRY THIS AFTERNOON. WILL REPRESENT THE POP TRENDS IN THE
GRIDS...BUT THOSE DETAILS ARE PROBABLY TOO FINE TO BE PICKED UP IN
THE TEXT ZONES. UPDATES TO THE GRIDS AND TEXT PRODUCTS WILL BE ISSUED
SHORTLY.

.PREV DISCUSSION...
339 AM EDT TUE JUN 20 2006

COOLER POCKET OF AIR RUSHING IN BEHIND THE DEPARTING S/W HAS LED TO
SOME ELEVATED CONVECTION ACROSS SOUTHERN IN AND NORTH CENTRAL KY.
BEST CORES ARE STAYING CLOSER TO THE JUICY AIR MASS SET UP WEST OF A
LEX TO SME LINE...BUT A FEW SHOWERS AND STORMS HAVE MADE IT INTO THE
I 64 CORRIDOR. DEWPOINTS BEHIND THE PREFRONTAL TROUGH WHICH KICKED
OFF A BROKEN LINE OF CONVECTION ACROSS EASTERN KENTUCKY EARLIER THIS
EVENING...HAVE COOLED TO THE UPPER 50S IN SOME SPOTS. EXPECT THE
CURRENT ACTIVITY TO CONTINUE TO WANE WITH TIME AS THE S/W PULLS
FURTHER AWAY. MAIN FRONTAL BOUNDARY IS STILL LOCATED WELL NORTH OF
THE OHIO RIVER AND WILL CONTINUE TO STAY NORTH OVER THE NEXT FEW DAYS
AS UPPER LEVEL RIDGING REASSERTS ITSELF ACROSS THE OH AND TN VALLEYS.

PREVIOUS FORECAST HAD A GOOD HANDLE ON THIS AND ONLY MADE MINOR
TWEAKS TO TEMP AND POP REGIMES. MADE NO ADJUSTMENTS BEYOND FRIDAY.

1109 PM EDT MON JUN 19 2006

CONVECTION HAS BEEN ON THE WANE WITH THE LOSS OF HEATING AND AS S/W
EXITS. HAVE CANCELLED THE REST OF THE WATCH AND HAVE UPDATED THE POPS
TO ONLY INCLUDE A SLIGHT CHANCE THE REST OF THE NIGHT. WILL MAKE A
FEW OTHER TWEAKS TO THE GRIDS TO ACCOUNT FOR LATEST TRENDS. UPDATE
OUT SHORTLY.

820 PM EDT MON JUN 19 2006

UPDATE ISSUED FOR THE ZONES AND TEXT PRODUCTS FOR THE NEW WATCH AND
ADJUSTMENTS TO THE POPS...SKY COVER AND WEATHER ATTRIBUTES. OTHERWISE
FRISKY GUST FRONT STORMS ARE MOVING THROUGH NORTHEAST KENTUCKY.
HOWEVER...A FEW MORE ORGANIZED CELLS ARE CROSSING CENTRAL KENTUCKY
WITH WHAT APPEARS TO BE A DEVELOPING COLD POOL. WILL WATCH THIS AND
ANYTHING THEY SPAWN CLOSELY...BUT WITH THE SUN SETTING AND A
SLIGHTLY DRIER BOUNDARY LAYER OVER EAST KENTUCKY DO EXPECT A GRADUAL
WEAKENING TREND TO ENSUE. UPDATE TO WEB GRAPHICS AND NDFD GRIDS WILL
BE ISSUED SHORTLY.

434 PM EDT MON JUN 19 2006

NEW SEVERE THUNDERSTORM WATCH HAS JUST BEEN ISSUED FOR
BATH...MONTGOMERY...ELLIOTT...ROWAN AND FLEMING COUNTIES UNTIL 10 PM
THIS EVENING. RADAR SHOWING A LINE OF THUNDERSTORMS MOVING ESE
THROUGH SRN INDIANA AND SWRN OHIO. LAPS DATA SHOWING CAPES AROUND
1500 J/KG IN THAT AREA...WITH A LIFTED INDEX OF -5 TO -7. NAM AND RUC
SHOWS VORT MAX AND SURFACE TROUGH MOVING THROUGH THIS EVENING. MOST
OF THE THUNDERSTORM ACTIVITY SHOULD BE WITH THIS FEATURE AS IT MOVES
SOUTHEAST. WILL KEEP 20 POPS IN FOR TUESDAY AND TUESDAY NIGHT. DIURNAL
CONVECTION IS POSSIBLE ON TUESDAY...WITH JUST A WEAK CAP IN PLACE INDICATED
ON MODEL SOUNDINGS. MODELS ARE INDICATING A WEAK VORT MAX MOVING
THROUGH TUESDAY NIGHT...SO I HELD ON TO 20 POPS FOR A POSSIBILITY OF
SOME CONVECTION MOVING THROUGH. WE COULD STILL SEE SOME DIURNAL
CONVECTION FOR WEDNESDAY INTO WEDNESDAY NIGHT. MODELS INDICATE
INSTABILITY IN PLACE. NO STRONG TRIGGER TO SET OFF CONVECTION...BUT
WITH INSTABILITY AND LACK OF A CAP I KEPT 20 POPS IN THE FORECAST.

FOR THE THURSDAY THROUGH MONDAY PERIOD...GENERALLY USED DGEX MODEL
FOR GUIDANCE. USED 20 POPS FOR THURSDAY...AS IT LOOKS LIKE THE LEAST
LIKELY DAY WE SHOULD SEE PRECIP...BUT I CAN/T RULE OUT SOME
CONVECTION FIRING IN THE HEAT AND HUMIDITY. TAPERED POPS UP SLIGHTLY
FOR FRIDAY AND SATURDAY AS A FRONT TO THE NORTH SINKS SLOWLY SOUTH.
GFS WAS AFFECTED BY CONVECTIVE FEEDBACK...PRODUCING STRONGER SURFACE
AND UPPER AIR FEATURES THAT APPEAR TO BE ANOMALIES. DGEX SEEMED LIKE
A MORE REASONABLE SOLUTION...AND WAS ALSO SIMILAR TO ECMWF. USED THE
HIGHEST POPS FOR SUNDAY AS THE BEST DYNAMICS AND MOISTURE SHOULD BE
MOVING THROUGH THE AREA. STILL KEPT 20 POPS FOR MONDAY WITH SOME
LINGERING MOISTURE...AND THE UNCERTAINTY OF THE FRONTAL POSITION BY
THEN. WE WILL BE IN AN UNSTABLE SUMMERTIME PATTERN THROUGH THE 7 DAY
PERIOD.

TEMPS WILL BE HOT...ESPECIALLY WEDNESDAY. DEW POINTS SHOULD RISE INTO
THE MID 60S TO AROUND 70...SO THE HUMIDITY WILL BE MORE NOTICEABLE.
WITH INCREASED CLOUD COVER...WENT WITH HIGH TEMPS GRADUALLY LOWERING
BY LATE IN THE WEEK AND OVER THE WEEKEND. USED A COMBINATION OF MOS
GUIDANCE...AND 850 MB TEMPS FOR THE MAX AND MIN TEMP FORECAST THROUGH
THE PERIOD.

.JKL WATCHES/WARNINGS/ADVISORIES...NONE.
