AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOUISVILLE KY
315 PM EST SUN JAN 22 2006

...LOCALLY HEAVY RAIN TONIGHT...

.SHORT TERM (TONIGHT AND MONDAY)...

THE FIRST ROUND OF PRECIPITATION IS OCCURRING OVER CENTRAL KENTUCKY
INTO SOUTH CENTRAL CENTRAL INDIANA AT MID AFTERNOON. THERE HAS BEEN
SOME DECREASE ACROSS THE SOUTHERN PART OF THE RAIN AREA. HOWEVER THE
NEXT ROUND OF PRECIPITATION IS MOVING NORTHEAST THROUGH NORTHEAST
TEXAS AND ARKANSAS.

MAIN CHALLENGES WITH TONIGHT/S FORECAST ARE TIMING THE PRECIPITATION
AND HOW HEAVY THE RAIN WILL BE. MODELS ARE GIVING THE SAME GENERAL
SOLUTION WITH MINOR DIFFERENCES IN TIMING THE ENDING OF THE RAIN
LATE TONIGHT AND MONDAY. THE GFS HAS HANDLED THE ONSET OF THE
PRECIPITATION WELL WITH THE NAM MUCH SLOWER TO ADVANCE THE RAIN
NORTHWARD. THE GFS BRINGS A QUICK HEAVY BAND OF RAIN ACROSS THE
CENTRAL AND SOUTHERN PARTS OF THE FORECAST AREA THIS EVENING AND INTO
THE EARLY OVERNIGHT HOURS. WHILE THE NAM SHOWS LIGHTER PRECIPITATION
BUT KEEPS THE HIGH RH IN A LITTLE LONGER. FOR THE MOST PART PREFER
THE GFS BUT WILL SLOW THE ENDING OF THE RAIN A FEW HOURS...BLENDING
HERE A LITTLE TOWARD THE NAM.

HEAVY RAIN STILL APPEARS ON TRACK...BOTH NAM AND GFS SHOW LOW LEVEL
JET INCREASING ACROSS SOUTHEAST KENTUCKY THIS EVENING WHILE AT THE
SAME TIME UPPER LEVEL JET RIGHT ENTRANCE REGION BRINGS UPPER LEVEL
DIVERGENCE ACROSS THE SOUTHERN PART OF THE FORECAST AREA. ISENTROPIC
LIFT ALSO INCREASES OVER THE AREA AFTER 00Z. CURRENT PLACEMENT OF
HEAVY RAIN AND FLOOD WATCH LOOK GOOD AND WILL LEAVE PLACE. WILL ALSO
KEEP ISOLATED THUNDER ACROSS THE FAR SOUTH...EXPECT ADDED LIFT FROM
JETS AND ISENTROPIC LIFT TO HELP TRIGGER THUNDER.

OTHER PROBLEM WILL BE TIMING THE ENDING OF THE PRECIPITATION. RAIN
SHOULD END OVER THE NORTHWEST SECTIONS BEFORE MORNING AND WILL END
ACROSS THE REST OF THE FORECAST AREA BY 18Z. WILL ALSO ALLOW CLOUDS
TO DECREASE FROM NORTHWEST TO SOUTHEAST ACROSS THE AREA...REACHING
THE SOUTHEAST AND EAST BY 00Z.

TEMPERATURES WILL STAY IN THE 30S OVERNIGHT THEN RISE ONLY INTO THE
MID AND UPPER 40S ON MONDAY.

SCHOLZ

.LONG TERM (MONDAY NIGHT THROUGH WEDNESDAY)...

NORTHWEST FLOW WILL DEVELOP DURING THIS FORECAST. HOWEVER WE WILL
SEE BACKING WINDS TUESDAY AFTERNOON IN RESPONSE TO A TROUGH DROPPING
THROUGH THE EASTERN GREAT LAKES. TEMPERATURES WILL RESPOND WITH
HIGHS EXPECTED TO WARM INTO THE MID 50S. WITH A NORTHWEST FLOW IN
PLACE WEDNESDAY TEMPERATURES WILL BE SOME 5 TO 10 DEGREES COOLER
THAN TUESDAY. SKIES WILL BE MOSTLY CLEAR EXPECT AS THE COOL FRONT
DROPS THROUGH THE REGION TUESDAY NIGHT.

(THURSDAY THROUGH SUNDAY)

UPPER LEVEL NORTHERN STREAM TROUGH WILL MOVE TO THE EAST COAST AT
THE BEGINNING OF THIS FORECAST PERIOD AND WE WILL SEE A RETURN TO A
ZONAL OR SOUTHWEST FLOW. MODELS ARE HAVING A HARD TIME WITH THE
EVENTUAL TRACK OF THE WESTERN UNITED STATES CLOSED LOW WITH THE GFS
BRINGING THE SYSTEM EAST ACROSS THE UNITED STATES WHILE THE EUROPEAN
AND CANADIAN MODELS WEAKEN IT AS IT MOVES NORTHEAST INTO THE GREAT
LAKES. EVEN THE GFS ENSEMBLE MEMBERS ARE HAVING A HARD TIME AT THE
END OF THE WEEK WITH A STANDARD DEVIATION OF 5 TO 8 FOR
TEMPERATURES AND 8 TO 10 FOR PRECIPITATION.

WITH THIS UNCERTAINTY AND POPS ONLY AROUND 30% WE WILL LEAVE THIS
FORECAST DRY FOR NOW.

WILL FOLLOW THE GFS ENSEMBLE AVERAGES.  - JA
