AREA FORECAST DISCUSSION...UPDATE
NATIONAL WEATHER SERVICE PADUCAH KY
1220 AM CDT SAT JUL 17 2004

.UPDATE...

SLOW MOVING NE/SW ORIENTED TROUGH FROM 925-500 MB SPRAWLED ACROSS
NRN LIMIT OF PAH FORECAST AREA. THIS WAS EVIDENT IN THE PROFILER
NETWORK AND DRY PUNCH ASSOCIATED WITH UPPER LEVEL JET IN THE WATER
VAPOR IMAGERY. MSAS MEAN SEA LEVEL PRESSURE SHOWING TWO MINOR SFC
LOW PERSISTING WEST OF FARMINGTON MO/KFAM/ AND BETWEEN MATTOON
/KMTO/ AND OLNEY /KOLY/ THE LAST FEW HOURS.

DEEP MOISTURE FROM SFC TO AT LEAST 700 MB STILL EVIDENT IN 00Z UPPER
AIR ANALYSIS. THE 925-850 MB MANUAL ANALYSIS SHOWS DECENT MOISTURE
RIDGE PARALLEL WITH UPPER TROF.

UPDATED ZONES FOR THE REST OF TONIGHT TO ENHANCE HEAVY RAIN
POTENTIAL OVER SWRN INDIANA...AS WELL AS ADJACENT PARTS OF SERN IL
AND NORTHWEST KY. THIS WILL KEEP FORECAST IN LINE WITH CURRENT SHORT
FUSE FLASH FLOOD AND URBAN/SMALL STREAM ADVISORIES FOR THE REST OF
TONIGHT. RUC AND GFS KEEP FOCUS OF HEAVY RAIN ACROSS SWRN IN THROUGH
AT LEAST 09Z.

.EVENING DISCUSSION...

ISOLATED STORMS NORTH OF INTERSTATE 64 CONTINUE TO MOVE SLOWLY
SOUTHEAST. LOOKING AT WATER VAPOR IMAGERY...THESE STORMS APPEAR TO
BE RELATED TO AN UPPER LEVEL JET STREAK OVER THE MID/UPPER
MISSISSIPPI VALLEY. RUC MODEL 250 MB PROGS SEEM TO HAVE A GOOD
HANDLE ON THIS FEATURE...TAKING 80 TO 90 KNOT JETLET ACROSS THE
WABASH VALLEY OVERNIGHT. WITH THIS IN MIND...WILL MAINTAIN THE
CHANCE POPS IN THE FORECAST OVERNIGHT. SLOW MOVEMENT OF THE
CONVECTION WILL RESULT IN LOCALLY VERY HEAVY RAIN...ESPECIALLY AS
THE STORMS MOVE INTO A HIGHER PW ENVIRONMENT OVER THE LOWER OHIO
VALLEY.

&&

.AFTERNOON DISCUSSION...

MAIN FORECAST CONCERN REMAINS THE CHANCE FOR LINGERING SHOWERS AND
THUNDERSTORMS TONIGHT...THEN IF ANY PRECIPITATION WILL OCCUR OVER
THE WEEKEND.

REMNANTS OF CONVECTIVE SYSTEM FINALLY EXITING THE FORECAST AREA AS
OF MID AFTERNOON...WITH RAIN SHOWERS LINGERING OVER THE PURCHASE
AREA OF WESTERN KENTUCKY. A FEW SHOWERS/STORMS HAD DEVELOPED OVER
THE EVANSVILLE TRI-STATE AREA IN RESPONSE TO DESTABILIZATION.
FORTUNATELY...THE ABUNDANT CLOUD COVER KEPT THE REST OF THE AREA
FROM REALLY EVER DESTABILIZING. AS A RESULT...OUR ATTENTION TURNS TO
THE CONVECTIVE ACTIVITY FIRING OVER THE UPPER MIDWEST ALONG A
SOUTHWARD-ADVANCING FRONTAL BOUNDARY. CURRENT THINKING IS THAT MOST
OF THIS ACTIVITY...IF IT EVEN HOLDS TOGETHER...WILL AFFECT MAINLY
AREAS TO OUR EAST TONIGHT. AS THE PUSH OF COOLER...DRIER AIR WILL
MAKE IT HERE OVERNIGHT...DID KEEP SMALL CHANCES IN THE FORECAST...
WITH HIGHEST POPS OVER EASTERN COUNTIES.

OVER THE WEEKEND...THE MODELS STILL CLOSE OFF AN UPPER-LEVEL LOW
OVER THE OHIO VALLEY WITH NORTH/NORTHWEST FLOW ACROSS THE FORECAST
AREA. IN THIS FLOW...THERE WILL LIKELY BE ENOUGH MOISTURE AROUND TO
RESULT IN INTERVALS OF CLOUDINESS...ESPECIALLY FROM LATE MORNING
THROUGH EARLY EVENING BOTH SATURDAY AND SUNDAY. HAVE PULLED ANY
MENTION OF PRECIPITATION FOR NOW...AS THE BEST COMBINATION OF
MOISTURE AND LIFT SHOULD STAY JUST EAST OF THE AREA.

BY SUNDAY NIGHT...THE UPPER LOW SHOULD BEGIN TO SHIFT EAST OF THE
REGION. FOR THE BEGINNING OF NEXT WEEK...A MAINLY DRY NORTHWEST
FLOW PATTERN IS EXPECTED TO PERSIST...WITH HIGH PRESSURE ANCHORED
OVER THE SOUTHWESTERN STATES AND A LOW PRESSURE TROUGH OVER THE
EASTERN STATES. THE GFS SHOWS THE PASSAGE OF AN UPPER-LEVEL TROUGH
ON TUESDAY...BUT THE BEST COMBINATION OF MOISTURE AND LIFT SHOULD
REMAIN EAST AND NORTHEAST OF THE AREA WITH THIS WEAK SYSTEM.

THE NEXT CHANCE FOR PRECIPITATION IS SLATED FOR THURSDAY AND
THURSDAY NIGHT...WHEN THE GFS FORECASTS THE NEXT FRONTAL PASSAGE.
OPTED TO TAKE THE DRY ROUTE FOR FRIDAY AS THE FRONT SAGS JUST SOUTH
OF THE MISSOURI/ARKANSAS AND KENTUCKY/TENNESSEE STATE LINES.

WITH REGARD TO TEMPERATURES...GENERALLY SPLIT THE DIFFERENCE BETWEEN
THE ETA AND GFS MOS GUIDANCE THROUGH THE WEEKEND. IN THE EXTENDED...
DID NOT STRAY FAR FROM GFS MOS...AS GOING FORECAST IS ALSO IN THE
BALLPARK.
