CURRENT ZONE FCST HAS CONDITIONS WELL COVERED. PCPN TRYING TO MOVE
INTO SERN KY...BUT STILL VERRRY LIGHT...AND ONLY INTO A COUPLE OF
COUNTIES.  HOWEVER...DEEP MOISTURE WITH 60 DEG F DWPTS IN WRN KY
MOVING EAST SO SHOULD SEE AN INCREASE IN OUR CWFA AND WILL CONTINUE
POPS FOR TONIGHT. MAIN ENERGY WITH S/WV TO MOVE UP THE OH RVR BUT
SHOULD TRAIL A TROF THROUGH AREA. TIMING WRONG FOR SVR WX BY THE

404 PM EST SAT NOV 9 2002

WINDS AND INCREASED CLOUD COVER WILL KEEP TEMPS UP TONIGHT. HAVE
OPTED TO GO WITH MIDDLE TO UPPER 50S. KEEPING A CHANCE POP THIS
EVENING AS SHORTWAVE IS PROGGED TO MOVE THROUGH OVERNIGHT. TOMORROW
MORNING MAY HAVE A SLIGHT BREAK IN THE CLOUD COVER AS S/W MOVES OUT
AND LEAVES US OUT AHEAD OF THE STRONG COLD FRONT. GOING TO GO WITH
AN AFTERNOON AND EVENING STRESS ON THE CONVECTION...AS BOUNDARY
BARRELS THROUGH LATER IN THE DAY. WIND PROFILE STILL LOOKS
IMPRESSIVE ALL THE WAY UP ALONG WITH GOOD MOISTURE TRANSPORT AND
TONS OF LIFT. THEREFORE WILL MENTION THE POSSIBILITY OF STRONG WIND
GUSTS IN SOME OF THE STORMS. STILL NOT READY TO KILL POPS COMPLETELY
MONDAY THROUGH LATE TUESDAY...AS LOW LEVEL MOISTURE IS STILL IN
PLACE ACROSS THE AREA AND SHORT WAVES ROTATING THROUGH OUT AHEAD OF
THE MAIN TROUGH WILL BE DIFFICULT TO PLACE AS WELL AS TIME.

1035 AM EST SAT NOV 9 2002

ZONE PACKAGE HAS THINGS COVERED PRETTY WELL. CLOUDS HAVE INCREASED
THIS MORNING ACROSS THE CWA AND THIS SHOULD KEEP THE TEMPS IN CHECK
TO SOME EXTENT. WITH STRONG SFC GRADIENT WINDS WILL BLOW TODAY
AROUND 15 MPH OR SO (BUT STRONGER IN THE MORE OPEN TERRAIN TO OUR
WEST).

BASED ON SAT PICS AND RADAR TRENDS...WILL UPDATE ZONES TO MAKE
MENTION OF AFTERNOON SPRINKLES OR MAYBE A 20 POP. AREA OF LIGHT PCPN
OVER CENTRAL KY IS MOVING STEADILY TO THE EAST...AIDED IN PART BY A
5H VORT MAX AND STRONG WINDS ALOFT. UPDATED ZONES AND GRIDS OUT
BEFORE LONG.

------------------------------------------------------------------
430  AM EST SAT NOV 9 2002

BIG CHALLENGE THIS FORECAST PERIOD IS HOW MUCH WARMING WILL OCCUR
AHEAD OF THE NEXT TROF. STRONG GRADIENT FLOW HAS KEPT THE BOUNDARY
LAYER WELL MIXED THIS MORNING AND EXPECT THAT THE STRONG WAA WILL
KICK IN BEFORE SUNRISE. CLOUDS ARE ON THE INCREASE AND THE
INSOLATION MAY BE KEPT DOWN A BIT...STILL ONLY EXPECT THAT TO
PREVENT A COUPLE OF DEGREES WARMING. DO NOT ANTICIPATE PCPN UNTIL
LATER TONIGHT.

NEXT BIG CHALLENGE IS THE FRONTAL BOUNDARY MOVING INTO THE REGION
SUNDAY. THIS APPEARS TO BE A SIGNIFICANT PUSH WITH THE POTENTIAL FOR
STRONG THUNDERSTORMS OVER THE OHIO RIVER VALLEY AND INTO THE EASTERN
COALFIELDS. THE TIMING IS CRITICAL. ALTHOUGH THE ETA CONTINUES TO
PUSH THIS FRONT THROUGH QUICKLY, THE UPPER LEVEL TROF AND ASSOCIATED
SYNOPTIC FORCING CONTINUES TO KEEP CLOUDS OVER EASTERN KENTUCKY
THROUGH MONDAY NIGHT. HAVE UPDATED GRIDS AND ZONES TO TREND DOWN THE
CHANCES OF PCPN MONDAY NIGHT...BUT THAT IS SHORT LIVED AS THE
CYCLONIC NORTHWEST FLOW REMAINS IN PLACE THROUGH THE EARLY PART OF
THE WORK WEEK.

PREVIOUS FORECAST PACKAGE WELL IN HAND.
