AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ST LOUIS MO
338 AM CDT SUN SEP 20 2009

.DISCUSSION...
/335 AM CDT SUN SEP 20 2009/

LARGE SCALE LIFT IN ADVANCE OF A WEAK SHORTWV TROF ROTATING ENE
THRU ERN KS/ERN OK AND SUSTAINED LOW LEVEL MOISTURE CONVERGENCE
HAVE BEEN RESPONSIBLE FOR A GROWING AREA OF RAIN AND EMBEDDED
THUNDERSTORMS ACROSS CENTRAL PORTIONS OF MO. SOME DECENT RAINFALL
AMOUNTS HAVE BEEN OCCURING WITH THE THUNDERSTORMS IN SOUTH CENTRAL
MO WHERE RAFL RATES ARE SEVERAL INCHES/HR. THE WHOLE PCPN AREA IS
PRESENTLY LIFTING NWD AND SHOULD SWING EWD THIS MORNING AS WELL...AS
THE AFOREMENTIONED SHRTWV TROF AND ACCOMPANYING LOW LEVEL
CIRCULATIONS LIFT NEWD. THIS WILL RESULT IN LIKELY POPS IN MOST
LOCATIONS TODAY. BY EARLY THIS EVENING I THINK ANY PCPN THREAT
THAT LINGERS WILL BE PRIMARILY ACROSS IL IN CONJUNCTION WITH THE
BETTER LOW LEVEL FORCING. GUIDANCE SUGGESTS THERE WILL BE QUITE A
BIT OF CLOUDINESS IN THE WAKE OF THE PCPN...WITH STRATUS AND FOG
DEVELOPING WHERE ANY CLEARING OR BREAKS OCCUR.

I THINK MONDAY FOR THE MOST PART WILL BE A DRY DAY WITH MAINLY
MORNING CLOUDS AND FOG. THERE CUD BE A RESIDUAL SHOWER EARLY OVER
FAR SOUTH CENTRAL IL. ACROSS CENTRAL MO I THINK THE MAJORITY OF
PCPN ASSOCIATED WITH THE NEXT CDFNT AND DEEPENING TROF WILL HOLD
OFF UNTIL MONDAY NIGHT. LOOKS LIKE THE CDFNT WILL BE A SLOW MOVER
GIVEN THE AMPLICATION OF THE PLAINS TROF/CLOSED LOW DEVELOPMENT...
WHICH SHOULD KEEP THE THREAT OF PCPN IN THE FORECAST THROUGH AT
LEAST TUESDAY NIGHT ACROSS PORTIONS OF ERN MO AND WRN IL. BEYOND
THAT PERIOD THERE IS QUITE A BIT OF UNCERTAINTY TO THE FORECAST
DUE TO THE FUTURE OF THE CLOSED LOW...AND DIDNT MAKE ANY
CHANGES...ALTHO ANOTHER SURGE OF PCPN IS PSBL IN THE THURS
NIGHT/FRI TIME FRAME.

TEMPS WILL BE SURPRESSED TODAY DUE TO CLOUDS AND PCPN WITH DECENT
RECOVERY ON MONDAY AFTER THE CLOUDS/FOG BREAK-UP.

.AVIATION...
/1141 PM CDT SAT SEP 19 2009/

FOR THE 06Z TAFS...SCATTERED SHOWER ACTIVITY IS PERSISTING OVER THE
REGION AS IT MAKES ITS WAY NORTHWARD TOWARDS KCOU/KSUS/KSTL...SO
KEPT VCSH MENTION THROUGH 13Z. OTHERWISE...MAIN FORECAST ISSUE WILL
BE CEILINGS LATER TODAY AS WEAK SURFACE LOW LIFTS NORTHEASTERLY AND
WEAKENS WITH TIME. WITH SO MUCH LOW LEVEL MOISTURE WOULD NOT BE
SURPRISED TO SEE SOME MVFR STRATUS AND/OR FOG FOR PORTIONS OF THE
AREA...ESPECIALLY TOWARDS 01Z...THOUGH HAVE SCATTERED MENTION OF
STRATUS AS EARLY AS 13Z THIS MORNING AT KSUS/KSTL. WILL NEED TO KEEP
A WATCHFUL EYE ON THE POSSIBLE LOW CIGS/VSBYS LATER TODAY AND
TONIGHT.
