AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ST LOUIS MO
312 PM CDT THU APR 3 2008
.DISCUSSION...
MAIN FORECAST CONCERN STILL DEALS WITH CONCERN FOR ADDITIONAL HEAVY
RAINFALL OVER THE SRN AND ERN PARTS OF THE CWA. RISK FOR WIDESPREAD
HEAVY RAINFALL HAS DECREASED AS ALL OF THE 12Z MODEL RUNS HAVE
PUSHED AXIS OF HEAVIEST RAINFALL TO THE SOUTHEAST OF THE CWA.
HOWEVER...AREA GROUND REMAINS VERY SATURATED AS THIS MORNINGS
RAIN BROUGHT ANOTHER 1/4 TO 3/4 OF AN INCH...AND EVEN THE QUICK
MOVING ELEVATED SUPERCELLS OVER CNTRL MO EARLIER THIS AFTERNOON
PRODUCED SOME MINOR FLOODING. SO WILL LEAVE THE FLASH FLOOD WATCH
AS IS THROUGH TONIGHT FOR THE THREAT OF LOCALLY HEAVY RAINFALL
PRODUCED BY INTENSE RAINFALL RATES FROM INDIVIDUAL THUNDERSTORMS.
AREA OF SHRA AND TSRA CURRENTLY OVER ERN MO/SWRN IL IS EXPECTED TO
CONTINUE TO PUSH EASTWARD THROUGH LATE AFTERNOON. ADDITIONAL TSRA
HAVE DEVELOPED OVER OK IN RESPONSE TO WEAK SHORTWAVE TROUGH
CURRENTLY MOVING ACROSS THE CNTRL PLAINS. DO EXPECT THIS AREA TO
SPREAD NEWD INTO THE CWA THIS EVENING. MUCAPES WILL INCREASE INTO
THE 500-1000 J/KG RANGE AND PRECIPITABLE WATERS CLIMB INTO THE
1-1.25 RANGE. ALSO WILL HAVE THE RISK FOR CONTINUED SEVERE
WEATHER AS 0-6KM SHEAR REMAINS IN THE 60-70KT RANGE. MAIN THREAT
WILL BE HAIL CAUSE BY ELEVATED SUPERCELLS. PRECIPITATION CHANCES
AND THE THREAT FOR HEAVY RAINFALL WILL BEGIN TO DECREASE BY LATE
TONIGHT AS THE BEST LOW LEVEL FORCING BEGINS TO SHIFT SOUTHEAST OF
THE CWA. WILL KEEP CHANCE OF SHRA OVER THE SERN COUNTIES INTO
TOMORROW MORNING AS THE MAIN TROUGH WILL TAKE A WHILE TO MOVE
THROUGH MO/IL. DRY WEATHER IS THEN EXPECTED THROUGH SUNDAY
AFTERNOON AS LARGE SCALE SUBSIDENCE AND LACK OF SIGNIFICANT
MOISTURE MOVES IN BEHIND TROUGH. A WEAK TROUGH AND ASSOCIATED COLD
FRONT WILL THEN MOVE INTO ACROSS MO/IL LATE SUNDAY AND SUNDAY
NIGHT WITH SCT SHRA/TSRA. AM NOT EXPECTING A GREAT DEAL OF
MOISTURE RETURNING AHEAD OF THIS FRONT...BUT GFS HAS STEEP MID
LEVEL LAPSE RATES AND A SHORT DURATION OF MODEST LARGE SCALE
ASCENT.
NAM AND GFS MOS TEMPERATURES ARE IN GOOD AGREEMENT AND FOLLOWED THEM
CLOSELY FOR TEMPS THE NEXT FEW DAYS.
STILL HAVE LOW CONFIDENCE IN THE EXTENDED PART OF THE FORECAST
(SUNDAY NIGHT TO NEXT THURSDAY) AS THE PATTERN ADJUSTS FROM ZONAL
FLOW EARLY IN THE WEEK TO A FAIRLY AMPLYFIED ONE BY THE MIDDLE OF
THE WEEK. MEDIUM RANGE MODELS HAVE SHOWN SOME SIGNIFICANT CHANGES
SINCE YESTERDAY AS BOTH THE GFS AND ECWMF ARE SHOWING DIFFERENCES THAT
CAUSES ADJUSTMENT IN TIMING OF CHANCES OF PRECIPITATION DURING THE
PERIOD. HAVE NO STRONG PREFERENCE FOR ANY OF THE MODELS...SO USED
A CONSENSUS OF THE CMC/GFS/ECMWF TO DECIDE WHEN TO HAVE SHRA/TSRA
IN THE FORECAST. HAVE KEPT CHANCE OF SHRA IN THE FORECAST SUNDAY
NIGHT AS FRONT MOVES THROUGH THE AREA. ALSO HAVE CHC OF SHRA/TSRA
NOW FOR MONDAY NIGHT/TUESDAY AS ANOTHER TROUGH/FRONT MOVES ACROSS
THE REGION AND CONTINUED THEM INTO NEXT THURSDAY AS THE DEEP TROUGH
BEGINS TO INFLUENCE THE AREA. TEMPERATURES ARE A COMBINATION OF
PERSISTENCE...HPC GUIDANCE AND MEAN GFS ENSEMBLE MOS.

.AVIATION...
FOR THE 18Z TAFS...
SCATTERED THUNDERSTORMS ACROSS CENTRAL AND SOUTH CENTRAL MO APPEAR
TO BE OCCURRING ON THE LEADING EDGE OF ASCENT ASSOCIATED WITH THE
SHORTWV TROF MOVING THRU ERN NEBRASKA AND ERN KS. THEY ARE ALSO
LOCATED ALONG THE ERN PERIPHERY OF ELEVATED INSTABILITY/STEEP MID
LEVEL LAPSE RATES. THE ENTIRE ZONE OF PCPN WILL SHIFT EWD WITH THE
MIGRATION OF THE SHORTWV BUT HOW LONG THE THUNDERSTORMS CAN
MAINTAIN THEMSELVES IS A LITTLE MORE QUESTIONABLE. HAVE INTRODUCED
THUNDER INTO THE KCOU TAF AND VCNTY IN THE STL AREA TAFS. IFR CIGS
SHOULD PREVAIL IN THOSE ALREADY SEEING THEM ALONG AND SOUTH OF
I-70 AND SHOULD GRADUALLY SPREAD INTO KUIN THIS EVENING. LOTS OF
UNCERTAINTY WITH THE PCPN TRENDS BEYOND THIS FIRST WAVE OF
SHOWERS AND THUNDERSTORMS FOR THE INDIVIDUAL TAF SITES...BUT FEEL
MAIN THEAT AREA TONIGHT WILL SHIFT TO SE MO AND SRN IL AND STL
WILL BE ON THE NRN FRINGE.

.HYDROLOGY...
RIVER FORECASTS THIS MORNING TAKE INTO ACCOUNT THE PRECIPITATION
FROM LAST NIGHT AND THE EXPECTED AMOUNT OVER THE NEXT 24 HOURS.
THEY SHOULD NOW BE FAIRLY REPRESENTATIVE OF WHAT IS EXPECTED ALONG
AREA RIVERS WHICH CALLS FOR MINOR TO SOME MODERATE FLOODING GOING
INTO THE WEEKEND. SEE LOCAL FLOOD STATEMENTS FOR FURTHER DETAILS.
