AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ST LOUIS MO
237 PM CDT SUN APR 16 2006

.DISCUSSION...
MAIN FORECAST CHALLENGES DEAL WITH HOW QUICKLY TSRA WILL EXIT THE
AREA TONIGHT...AND CHANCES OF TSRA AGAIN WITH COLD FRONT THAT WILL
MOVE ACROSS THE REGION LATE TUESDAY INTO WEDNESDAY.  GFS/NAM ARE IN
PRETTY GOOD AGREEMENT WITH MOVING THE UPPER LOW CURRENTLY OVER IA
EASTWARD AND PHASING IT WITH THE LARGER UPPER LOW OFF THE NERN U.S.
COAST.  MEANWHILE...UPPER TROUGH NOW ENTERING NW PAC COAST WILL MOVE
EWD THRU THE ROCKIES AND EVENTUALLY CLOSE OFF OVER THE N CNTRL CONUS
BY TUESDAY NIGHT.

AREAL CONVERAGE AND INTENSITY IS EXPECTED TO GRADUALLY INCREASE OVER
FAR ERN MO AND OVER IL LATE THIS AFTERNOON/EARLY EVENING.  LATEST
SPC MESOANALYSIS SHOWS LOW LEVEL CONVERGENCE IS CONTINUING TO
INCREASE ALONG SFC COLD FRONT AT THE SAME TIME MLCAPES HAVE
INCREASED >1,000 J/KG WITH LITTLE CINH ALONG THE FRONT.  DEEP LAYER
SHEAR IS CONDUCIVE FOR SUPERCELL DEVELOPMENT.  RUC SHOWS THAT THIS
FRONT WILL CLEAR THE ERN PART OF THE CWA BY MID EVENING...SO WILL GO
DRY OVERNIGHT.  WILL THEN BE DRY FOR MONDAY INTO MOST OF TUESDAY AS RIDGE
BUILDS OVER AREA IN BETWEEN SYSTEMS.  CHC OF TSRA WILL RETURN ON
TUESDAY NIGHT INTO WEDNESDAY AS LOW LEVEL MOISTURE CONVERGENCE AND
LARGE SCALE UPWARD MOTION CAUSED BY UPPER TROUGH MOVES THROUGH
MO/IL.  INTENSE TSRA LOOKS LIKE THEY WILL DEVELOP OVR ERN KS AND WRN
MO ON TUE AFTN/EVENING AND MOVE EWD...AND FORECAST INSTABILITY
DEPICTED BY NAM HAS MUCAPES (MAINLY ELEVATED PARCELS) IN THE
400-2,000J/KG RANGE. WILL KEEP MENTION OF POTENTIAL SEVERE IN THE
HWO.

TEMP GUIDANCE IS IN GENERAL AGREEMENT AND HAVE FOLLOWED A BLEND.

IN THE EXTENDED (THU-SUN)...HAVE NOT MADE TOO MUCH CHANGE THROUGH
NEXT WEEKEND.  SAME IDEA AS YESTERDAY THAT CLOSED LOW WILL MOVE
NEWD...AND BEST MOISTURE AND INSTABILITY WILL STAY SOUTH OF THE AREA
ONCE THE MIDWEEK FRONT MOVES THROUGH. DID GO WITH THE SLOWER IDEA
OF FRONTAL PASSAGE THOUGH LIKE THE ECMWF WHICH MAKES MORE SENSE
WITH A CLOSED LOW. UPPER RIDGE WILL BUILD IN AS THE LOW MOVES
EWD...ALLOWING FOR NEXT WEEKEND TO BE DRY.

BRITT

.AVIATION...
FOR THE 18Z TAFS...TSRA CHANCES WILL BE GREATEST INVOF CDFNT NOW
MOVING THRU THE FA...WITH A WIND SHIFT TO WSW EXPECTED AFTER
FROPA. THEN LOOK FOR CIGS TO BEGIN FALLING AS LO LEVEL WINDS
EVENTUALLY GAIN A NLY COMPONENT AND ARE ABLE TO DRAW IN THE LOWER
CIGS ALREADY IN PLACE ACROSS IA. EXPECT MVFR CIGS BY LATE TONIGHT
FOR ALL LOCATIONS...WITH AREAS DIPPING INTO IFR RANGE FOR AREAS
ACROSS THE STL METRO AREA AND N AND E. A SLOW RECOVERY IN CIGS
THEN EXPECTED FOR MONDAY MORNING WITH MORE SIGNIFICANT IMPROVMENT
AROUND MIDDAY.
