Area forecast discussion, Mar 29, 9:25 PM CDT, 43 minutes before

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE ST LOUIS MO
925 PM CDT SUN MAR 29 2009

.UPDATE...
/925 PM CDT SUN MAR 29 2009/

NO UPDATES ANTICIPATED. THIN CI CLOUDS MOVING OVERHEAD NOW
SPILLING OVER LO-AMPLITUDE MID AND UPR LEVEL RIDGE WHICH IS IN
PLACE OVER THE CNTRL CONUS. BEST CHC FOR PATCHY FOG WILL REMAIN TO
THE E OF KSTL OVER SWRN IL WHERE THEY WERE THE LAST TO CLEAR OUT
THIS AFTN. TEMPS LOOK ON TARGET WITH AOB MEAN MOS VALUES
EXPECTED.

.DISCUSSION...
/309 PM CDT SUN MAR 29 2009/

MAIN FORECAST CONCERN DEALS WITH PRECIPITATION CHANCES MONDAY NIGHT
INTO TUESDAY.  UPPER LOW THAT BROUGHT SNOW TO PARTS OVER THE REGION
LAST NIGHT HAS ALREADY MOVED INTO THE ERN GREAT LAKES AND SKIES HAVE
CLEARED OVER ALL BUT THE ERN PART OF THE CWA.  SNOWFALL HAS MELTED
RAPIDLY TODAY INCLUDING THE 3-5 INCH REPORTS OVER E CNTRL MO/SWRN IL
BECAUSE OF THE STRONG LATE MARCH SUN AND TEMPERATURES CLIMBING INTO
THE MID 40S.  LOWS TONIGHT WILL BE INFLUENCED BY SURFACE RIDGE AXIS
NOW OVER WRN MO THAT WILL MOVE ACROSS THE CWA TONIGHT WHICH WILL
ALLOW WINDS TO TURN SELY AND INCREASE SLIGHTLY OVER CNTRL MO TOWARD
DAYBREAK.  SAME AREA WILL BE THE FIRST TO SEE CIRRUS CURRENTLY OVER
THE CNTRL HIGH PLAINS TO MOVE IN TONIGHT...SO HAVE WARMEST LOWS
OVER CNTRL MO...AND THE COOLEST OVER W CNTRL AND S CNTRL IL WHICH
WILL RADIATE THE BEST. THIS FALLS IN LINE WITH A NAM MOS/2M SREF
MEAN FOR LOWS. GROWING SEASON HAS NOT STARTED YET OVER THE NRN
AND ERN PART OF THE CWA...SO NO NEED YET FOR A FROST/FREEZE
HEADLINE. HAVE ALSO SCALED BACK PATCHY FOG TO S CNTRL IL WHERE
THERE HAS BEEN LITTLE MIXING SO TEMPERATURES WILL FALL CLOSE TO
DEWPOINTS.

THERE IS NOT THAT MUCH DIFFERENCE BETWEEN THE GFS/NAM THAT WILL
AFFECT THE SENSIBLE WEATHER WITH THE SYSTEM MONDAY NIGHT/TUESDAY.
CHANCES OF PRECIPITATION WILL INCREASE GREATLY BY MONDAY EVENING AS
50KT LOW LEVEL JET CAUSES DECENT LOW LEVEL MOISTURE CONVERGENCE/
TRANSPORT AT THE SAME TIME LARGE ASCENT INCREASES IN ADVANCE OF
STRONG UPPER LOW/ACCOMPANYING TROUGH. HAVE KEPT LIKELY POPS GOING
INTO TUESDAY AHEAD OF THE COLD FRONT...AND CUT POST FRONTAL POPS.
HAVE GONE WITH JUST CHANCE OF TSRA WITH THIS SYSTEM AS GFS IS
SHOWING MID LEVEL INSTABILITY...BUT VERY LITTLE MUCAPE.

FOR TEMPERATURES BEYOND TONIGHT...HAVE SIDED WITH WARMER GFS MOS FOR
TEMPS ON MONDAY GIVEN THE WARM AIR ADVECTION AND SUNSHINE WE WILL
SEE MOST OF THE DAY. ALSO FOLLOWED THE GFS MOS CLOSELY THROUGH
TUESDAY NIGHT.

UPPER PATTERN IN THE EXTENDED GOES FROM A BROAD TROUGH OVER THE
CENTRAL CONUS WITH SHORTWAVES OVER THE ERN GREAT LAKES AND THE SRN
ROCKIES TO A MORE AMPLIFIED TROUGH WITH RIDGES OVER THE EAST COAST
AND ROCKIES BY SUNDAY. THE OPERATIONAL RUNS OF THE GFS/ECMWF ARE
IN RELATIVELY GOOD AGREEMENT WITH THE TIMING AND AMPLITUDE WITH
THESE SYSTEMS UNTIL SUNDAY WHEN GFS IS FARTHER NW WITH UPPER LOW
THAN THE ECWMF. EVEN WITH THIS SMALL DISAGREEMENT...THEY AGREE
ENOUGH TO USE A BLEND OF THE TWO FOR THE FORECAST. WITH THIS IN
MIND...HAVE KEPT CHANCE OF SHRA WEDNESDAY NIGHT/THURSDAY AS TROUGH
MOVES ACROSS MO/IL AND THEN AGAIN SATURDAY NIGHT/SUNDAY AS
ANOTHER/DEEPER TROUGH MOVES IN FROM THE WEST. FORECAST
TEMPERATURES/CRITICAL THICKNESSES KEEP PRECIPITATION AS ALL LIQUID
FOR NOW AS WE GO INTO EARLY APRIL.

.AVIATION...
/642 PM CDT SUN MAR 29 2009/

FOR THE 00Z TAFS...PRIMARY EMPHASIS OF FORECAST EVOLVES AROUND
WIND DETAILS. GUSTY WEST WINDS OF LATE THIS AFTN WL RPDLY TAPER
OFF NEXT HOUR OR TWO AS SFC RIDGE PROGRESSES THROUGH AND E OF
MSVLY...FOLLOWED BY INCREASING SE WINDS ON MON AS GRADIENT
INTENSIFIES IN ADVANCE OF LOW PRESSURE SYSTEM DEVELOPING OVER
PLAINS. ONLY TRUE WX CONCERN IS THE POTENTIAL OF FOG DUE TO VRY
WET GROUND. IT WOULD CERTAINLY APPEAR THAT MIXING DURING THE
PREDAWN HOURS WILL LIMIT THIS THREAT...WITH PERHAPS THE EXCEPTION
OF SUS WHERE RIVER VALLEY INVERSION WL INHIBIT MIXING UNTIL AFT
12Z. HAVE CONTINUED MENTION OF MVFR VSBYS AT SUS FOR SVRL HRS
