AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PADUCAH KY
200 PM CDT FRI APR 22 2005

MAIN CONCERNS ARE THE LINGERING EFFECTS OF THIS UPPER LOW TONIGHT
AND EARLY SATURDAY...THEN WITH POSSIBLE WIDESPREAD FREEZE SUNDAY
MORNING.

CURRENT WEATHER SITUATION IS CHARACTERIZED BY AN UPPER LEVEL LOW
NEAR KSTL WITH A VERY STRONG SHORTWAVE ASSOCIATED WITH IT. AS OF
100PM...CU FIELD ALREADY BEGINNING TO POP AND WE EXPECT RAPID
DEVELOPMENT HERE THIS AFTERNOON. WILL WAIT UNTIL PRESS TIME TO
DECIDE ON HOW TO ORIENTATE POPS FOR TONIGHT GIVEN LATEST RADAR
TRENDS. WE NOW HAVE A SVR THUNDERSTORM WATCH FOR OUR EASTERN
COUNTIES. PRIMARY THREAT WILL BE LARGE HAIL AND DAMAGING WINDS.

MAIN CONCERN TONIGHT WILL BE REMNANT PRECIP IN ASSOCIATION WITH THIS
UPPER LOW. MODELS STILL DEVELOPING VERY DEEP AND CLOSED OFF UPPER
LEVEL CYCLONE JUST TO OUR EAST FOR THE WEEKEND...RESULTING IN MUCH
COOLER WEATHER. WITH STRONG NORTHWEST WINDS...IT WILL BE QUITE
BLUSTERY...ESPECIALLY ON SATURDAY.  H85 TEMPS TAKE A NOSE DIVE
BEGINNING LATE TONIGHT...AND CONTINUE TO DROP INTO SATURDAY. THIS
WILL RESULT IN HIGH TEMPERATURES ON SATURDAY TO BE IN 50 TO 57
RANGE...WITH COOLEST READINGS IN CLOUDIER AREAS OF SW INDIANA AND NW
KY. NAM/GFS BRING ANOTHER PIECE OF ENERGY DOWN THE BACK SIDE OF THE
UPPER LOW SATURDAY...WHICH COULD RESULT IN A FEW SHOWERS ACROSS OUR
EASTERN COUNTIES...SO OPTED TO ADD A 20 POP IN THOSE LOCATIONS. THIS
LINES UP BETTER WITH OUR EASTERN NEIGHBORS.

H85 TEMPS CONTINUE TO DIVE EVEN FURTHER ON SATURDAY NIGHT...TO WHERE
H85 TEMPS RANGE FROM -5 TO -8 DEG C BY SUNDAY MORNING...SO SFC TEMPS
WILL BE CLOSE TO FREEZING IN MOST AREAS. WINDS SHOULD STAY UP
SATURDAY NIGHT/SUNDAY MORNING...SO A FREEZE WARNING MAY BE
NEEDED...BUT FROST SHOULD NOT BE AN ISSUE DUE TO THE WINDS STAYING
UP. SO HAVE HOISTED A FREEZE WATCH FOR NOW FOR ALL AREAS.

BY SUNDAY AFTERNOON...THE 06Z GFS AND 00Z ECMWF ARE IN GOOD
AGREEMENT AND SHOW MAIN RIDGE AXIS OVER THE CENTRAL PLAINS...WITH
THE WOUND UP SURFACE/UPPER LEVEL SYSTEM OVER THE EASTERN GREAT LAKES
REGION.

BY SUNDAY EVENING...A SURFACE LOW DEVELOPS IN THE EASTERN ROCKIES
AND SLIDES SOUTH A BIT INTO THE SOUTHERN PLAINS AND THEN EAST TOWARD
THE AREA. THE ETA IS FASTER IN BRINGING THIS LOW EASTWARD...MEANING
WE COULD HAVE A CHANCE OF PRECIP IN OUR WESTERN COUNTIES MONDAY
AFTERNOON. THE GFS ALSO INDICATES THAT PRECIP COULD BEGIN IN OUR
WESTERN COUNTIES BY LATER IN THE AFTERNOON. SO WILL ADD A SLIGHT
CHANCE POP IN OUR WESTERN COUNTIES AFTER 18Z MONDAY. THE 12Z GFS
INDICATES A 40KT H85 JET AHEAD OF THE FRONT ON MONDAY NIGHT...WHICH
COULD ACT TO ENHANCE THINGS A BIT...AND WE ALREADY HAVE A MENTION OF
POSSIBLE STRONG STORMS IN THE HWO FOR THIS TIME PERIOD. THE COLD
FRONT ASSOCIATED WITH THIS SYSTEM IS FORECAST TO BISECT THE AREA BY
12Z TUESDAY.

HIGH PRESSURE SHOULD BUILD INTO THE AREA FOR WEDNESDAY AND 850MB
TEMPS ONCE AGAIN FALL BELOW ZERO AS EARLY AS LATE TUESDAY NIGHT
BEHIND FRONT...SO WILL OPT TO LOWER TEMPS A BIT FOR WED MORNING AND
AFTERNOON. A WEAK FRONT WILL ATTEMPT TO BREAK DOWN THE SFC RIDGE
WEDNESDAY NIGHT INTO THURSDAY...BUT ACCORDING TO THE NEW GFS...THE
RIDGE REMAINS STRONG ENOUGH TO WARD OFF ANY PRECIP. HOWEVER BY
THURSDAY...ANOTHER SFC LOW DEVELOPS ACROSS THE ROCKIES AND MOVES
EAST WITH TIME AND A FRONTAL BOUNDARY SETS UP ACROSS OUR CWA BY
THURSDAY NIGHT AND INTO EARLY FRIDAY. THE PREVIOUS RUN OF THE GFS
DOES NOT SEEM TO HAVE THIS SAME OUTPUT. WITH MANY OTHER THINGS TO
WORRY ABOUT IN THE NEAR TERM (I.E. SEVERE WX EARLY
TONIGHT...FREEZING TEMPS POSSIBLE SUNDAY MORNING...EARLY WEEK PRECIP
CHANCES)...WILL LEAVE DRY FOR NOW.

GUIDANCE TEMPS NOT TOO FAR OFF FROM ONE ANOTHER...WILL FOLLOW
CLOSELY. ONLY MINOR DOWNWARD TWEEKS ARE REALLY NECESSARY THOUGH.
