AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PADUCAH KY

.UPDATE...
UPDATED FOR 12Z AVIATION FORECAST DISCUSSION.

..SIGNIFICANT HEAVY RAIN EVENT APPEARS INCREASINGLY LIKELY FRIDAY
NIGHT THROUGH SUNDAY...
.DISCUSSION...
BIGGEST CHALLENGE WITH THIS PACKAGE WILL BE THE HANDLING OF THE
HEAVY RAIN EVENT.
THE STAGE IS BEING SET FOR A SIGNIFICANT HEAVY RAIN EVENT FRIDAY
NIGHT THROUGH SUNDAY EVENING...OVER ABOUT A 48 HOUR PERIOD. MOST
AREAS WILL BE AFFECTED TONIGHT AND SATURDAY NIGHT...AND THEN
SUNDAY ACROSS THE PENNYRILE REGION OF WEST KENTUCKY. A FLASH FLOOD
WATCH IS IN EFFECT THROUGH SUNDAY AFTERNOON.
THE SYNOPTIC SCENARIO IS RATHER SIMPLE. A FRONTAL BOUNDARY WILL
MOVE INTO THE QUAD STATE REGION TONIGHT AND DUE TO DEEP SOUTHWEST
FLOW ALOFT OVER THE REGION...THE BOUNDARY WILL BECOME STATIONARY.
IN THE MEANTIME STRONG SOUTHERLY WINDS WILL BRING COPIOUS AMOUNTS
OF TROPOSPHERIC MOISTURE INTO THE AREA. WITH THE ACTIVE BOUNDARY
IN THE VICINITY COUPLED WITH HIGH MOISTURE LEVELS AND A STEADY
BARRAGE OF EMBEDDED UPPER LEVEL DISTURBANCES IN THE SOUTHWEST FLOW
ALOFT...MOST AREAS HAVE THE POTENTIAL FOR GETTING MULTIPLE INCHES
OF RAIN THROUGH SUNDAY. THE KEY TO THE GREATEST RAIN POTENTIAL WILL BE
WHERE THE ACTIVE BOUNDARY SETS UP...AND HOW LONG IT REMAINS THERE.
MODELS ARE SUGGESTING THAT SOUTHEAST OF A PRINCETON INDIANA TO
DEXTER MISSOURI LINE...2 TO 5 INCHES OF RAIN WILL BE
POSSIBLE...WITH 5 TO 7 INCH AMOUNTS POSSIBLE IN ENHANCED ZONES OF
CONVECTION. UNFORTUNATELY IT IS NOT UNCOMMON FOR THE MODELS TO
UNDERESTIMATE STORM TOTAL VALUES FOR SOME LOCALES IN A PATTERN
SUCH AS THIS. THE KEY WILL BE A STEADY STREAM OF DEEP MOISTURE
TRANSPORT FROM THE GULF REGION THROUGH THE PERIOD...WITH ITS
CULMINATION AND SPEED CONVERGENCE BEING FOCUSED ACROSS THE LOWER
OHIO...MID MISSISSIPPI AND TENNESSEE VALLEY REGIONS.
SOMETIMES CONVECTION TO OUR SOUTH WILL IMPEDE THIS INFLUX...BUT
MODELS ARE INCREDIBLY CONSISTENT WITH RESPECT TO KEY PARAMETERS
FAVORABLE FOR HEAVY RAIN...AND ARE INCREASINGLY CONSISTENT IN QPF
AMOUNTS. THE AREA OF GREATEST CONCERN IS WEST KENTUCKY...PORTIONS
OF SOUTHEAST MISSOURI...THE SOUTHERN TIP OF ILLINOIS AND SOUTHWEST
INDIANA. THE FARTHER NORTH AND WEST YOU GO...THE LESS TOTAL QPF WE
EXPECT. SATURDAY NIGHT INTO SUNDAY COULD YIELD SOME OF THE MORE
IMPRESSIVE RAIN AMOUNTS...AS THE UPPER JET DYNAMICS WILL BE MORE
IN PHASE WITH THE LOW LEVEL JET. SUNDAY...THE FOCUS SHOULD SHIFT
MOSTLY INTO WEST KENTUCKY AND PERHAPS A SMALL PART OF SOUTHWEST
INDIANA...SO THE WATCH OVER THE NORTHWEST PART OF THE AREA MAY BE
CANCELLED EARLY.
THE KEY FOR SEVERE POTENTIAL WILL AGAIN BE INSTABILITY...OR THE
LACK THEREOF. MODELS SHOW SLIGHTLY THE MOST FAVORABLE INSTABILITY
PARAMETERS OVER SOUTHEAST MISSOURI THIS EVENING. THE ENTIRE REGION
IS IN THE DAY 2 AND DAY 3 OUTLOOK FOR SLIGHT RISK. HOWEVER...
USUALLY IN A PATTERN LIKE THIS...THE SEVERE THREAT IS SOMEWHAT
LIMITED DUE TO GREATER MOISTURE THROUGHOUT THE COLUMN RESTRICTING
EVAPORATIVE POTENTIAL...AND A WARMER THERMAL PROFILE LIMITING THE
PRODUCTION OF HAIL. CANNOT RULE IT OUT COMPLETELY. WILL CONTINUE
TO MONITOR.
&&
.AVIATION...
WINDS WILL PICK UP BY 14-15Z TODAY...AND THEY ARE ALREADY GUSTING
AT KCGI/KPAH ATTM. SHOULD SEE SOME GUSTS IN THE 20-25KT RANGE. LOW
VFR CIGS HAVE MOVED INTO SOUTHEAST MO...SOUTHWEST IL AND FAR
WEST KY THIS MORNING. THESE CLOUDS WILL CONTINUE TO OVERSPREAD THE
REST OF THE AREA. MVFR CIGS ARE NOTED TO OUR SOUTH AND WILL
LIKELY IMPACT KCGI AND KPAH SOON. SOME SCATTERED LIGHT -SHRA COULD
IMPACT KCGI/KPAH FROM MIDDAY THROUGH MID AFTERNOON. HOWEVER...BETTER
CHANCES OF SHRA/TSRA WILL BEGIN OVER SOUTHEAST MISSOURI BY THIS
EVENING. THIS ACTIVITY WILL THEN MOVE EAST TO ENCOMPASS THE REST
OF THE TERMINALS BY 06Z AND BEYOND.
