AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ST LOUIS MO
1151 AM CDT MON APR 7 2008

.DISCUSSION...
00Z MODEL OUTPUT CONTINUES TO INDICATE TWO WAVES OF UNSETTLED WX FOR
THE REGION DURING THE UPCOMING WORK WEEK...THE FIRST BGNG LT
TNGT...CONTG ON TUE...THEN EXITING AREA BY TUE EVE...WITH WAVE #2
OCRG IN THE WED NGT-THU-THU NGT TIME FRAME.

IN GENL...ONLY MINOR CHGS NEEDED TO GOING FCSTS DUE TO THE GOOD RUN
TO RUN CONSISTENCY BEING EXHIBITED BY MODELS.   FOR THE FIRST 36 HRS
OF THE FCST THE PRIMARY TWEEKS WERE TO DELAY ONSET OF PCPN LTR TNGT
IN THE E AREAS OF THE FA...AND TO GO WITH A MORE S TRACK OF THE SFC
LO ON TUE.  ECMWF AND UKMET HAD BEEN HINTING AT A MORE N TRACK OF
THE LOW...BUT CONSENSUS NOW SEEMS TO SUGGEST RUFLY A JLN-SPI
CORRIDOR IN THE 18Z TUE-00Z WED TIME FRAME. HV ATTEMPTED TO
SHARPEN UP THE MAX TEMP GRADIENT BASED ON THIS TRACK...WITH MAX
TEMPS RANGING FROM ARND 50 IN OUR XTRM NW COUNTIES TO ARND 70 IN
OUR S COUNTIES WHICH SHUD GET WELL INTO THE WARM SECTOR DURING THE
AFTN.

BASIC SCENARIO FOR PCPN DVLPMT AND SVR WX TRENDS IN THE 12-36 HR
TIME PD RMNS THE SAME...WITH ELEVATED TSRA OVRSPRDG AREA LT TNGT

TO INCLUDE WIND AND A FEW TORNADOES. SHEAR IS CERTAINLY FAVORABLE
FOR SUPERCELLS...BUT BIG QUESTION MARK WRT EXTENT OF SVR WX IS AMT
OF INSTABILITY THAT WL BE REALIZED IN AND NR THE WRM SECTOR.

DUE TO THE RECENT WET WX...ANOTHER CONCERN FOR TUE AND TUE EVE IS
HVY RAIN THRT.  MOST WDSPRD AND HVIEST QPF WL BE IN THE ZN OF VRY
INTS LFT ASSOC WITH WAA/ISENTROPIC LIFT OCRG AHD OF THE LOW.  IT
APRS THAT THIS WL BE OCRG PRIMARILY IN N SECTIONS OF OUR FA...WHICH

HVY RAINS WL OCR WITH STGR TSRA THAT FORM DURG THE AFTN.

TSRA SHUD TAPER OFF FROM W TO E DURG THE LT AFTN AND EVE TUE WITH
PASSAGE OF CDFNT. HV ENDED MOST OF THE PCPN BY 06Z...AS EXPECT
THAT STG CNVTN WL PUSH THE BULK OF THE TSRA WELL AHD OF THE CDFNT
BY THAT TIME. THERE SHUD BE A BRIEF BRK IN THE WET WX ON WED...BFR
A REPEAT PERFORMANCE OCRS WITH ROUND TWO WED NGT...THU...AND THU
NGT. 00Z RUNS DO BGN TO DIVERGE CONSIDERABLY WITH THE SPECIFICS

YIELDED A MORE WDSPRD SWATH OF ELEVATED TSRA IN THE WAA PTRN AHD
OF THIS SYS. GFS OUTPUT...WHICH FOCUSES WED NGT CNVTN OVR THE S IN
RESPONSE TO WK WAVE AHD OF MAIN SYS...LOOKS TO BE CNVTVLY INDUCED

ULTIMATELY DETERMINE WHERE AND WHEN MOST OF THE ACTION OCRS...THE
INTENSITY OF UPR LVL TROF...PROGGED WIND FIELDS...AND AVBL MSTR
SUGGEST THAT MORE HVY RAIN AND SVRL ROUNDS OF SVR WX WILL BE A VRY
