AREA FORECAST DISCUSSION...UPDATED FOR FLASH FLOOD WATCH
NATIONAL WEATHER SERVICE SPRINGFIELD MO
340 PM CDT TUE OCT 9 2001

DECIDED TO ISSUE A FLASH FLOOD WATCH FOR WEDNESDAY FOR OUR WESTERN
ZONES.

LOOKS LIKE ACTIVE WEATHER PATTERN SETTING UP AS ADVERTISED THIS
AFTERNOON. EXPANDING AREA OF SHOWERS/STORMS EXTENDS FROM PARSONS
SEWD TO NEAR FORT SMITH. EXPECT THIS AREA OF PRECIP TO CONTINUE
SPREADING NORTHEAST AS INITIAL SHORTWAVE MOVES ACROSS THE REGION.
LATEST AVN SEEMS TO HAVE THE BEST HANDLE ON FIRST ROUND OF PRECIP.
SECOND ROUND DEVELOPING OVER CENTRAL KS/WEST CENTRAL OK WILL MOVE IN
AROUND MIDNIGHT.

HAVE BEEN LOOKING AT SEVERE WEATHER AND HEAVY RAINFALL PARAMETERS
FOR EARLY PERIODS. MESOETA SOUNDING FORECAST SHOW LIS FROM -1 TO -5
WITH CAPES AS HIGH AS 1800 J/KG. HELICITY VALUES ARE JUMPING UP TO
OVER 450 M2/S2 TONIGHT...NO SUPRISE THERE WITH GIVEN/FORECAST WIND
PROFILES. OVERALL THERE IS ENOUGH POTENTIAL GIVEN APPROACHING
DYNAMICS TO CONTINUE MENTION OF SEVERE IN ZONES FOR
TONIGHT...ESPECIALLY OVER AREAS WEST OF SPRINGFIELD. CHECKING OUT
HEAVY RAIN POTENTIAL...PWS AVERAGE 1-1.5 INCHES WITH K INDICES
HOVERING AROUND 30. PROGGED FAST MOVEMENT OF STORMS SHOULD LIMIT
FLOOD THREAT...BUT TWO OR THREE BLASTS OF HEAVY RAIN MAY BE ENOUGH
TO PRODUCE FLOODING IN LOW/FLOOD PRONE AREAS.

STILL EXPECT FROPA BEGINNING LATE WEDNESDAY AFTERNOON FOR NORTHWEST
ZONES...THEN CLEARING AREA BY MIDNIGHT THURSDAY. CURRENT TREND WITH
PRECIP THROUGH THURSDAY MORNING STILL LOOKS GOOD...WITH DRY
CONDITIONS THROUGH EARLY FRIDAY. WILL BRING MENTION OF PRECIP BACK
IN ZONES FOR FRIDAY NIGHT THROUGH SATURDAY...AS SECONDARY FRONT AND
COLDER AIR PUSHES INTO THE REGION. ALSO CONTINUED TREND OF COOLER
TEMPERATURES FOR SUNDAY THROUGH TUESDAY. LATEST MRF INTRODUCES
PRECIP ON MONDAY. HOWEVER...WITH TOO MUCH INCONSISTENCY FROM
PREVIOUS RUN...WILL LEAVE FORECAST DRY FOR NOW.
