.DISCUSSION...
/351 PM CDT TUE MAY 13 2008/
SEVERAL WAVES OF SCATTERED ELEVATED THUNDERSTORMS WHICH HAVE
TRAVERSED PORTIONS OF THE AREA TODAY HAVE MUDDIED THE FORECAST FOR
TONIGHT. THE ASSOCIATED CLOUD COVER AND COOL AIR FROM THE
THUNDERSTORMS HAVE HAMPERED WARMING OVER MUCH OF EASTERN MO AND IL.
THIS SEEMS TO BE THE STORY THIS SPRING WHEN WE GET A DECENT COLD
FRONTAL PASSAGE. ANYWAY THERE WILL BE SOME LOW LEVEL AIR MASS
RECOVERY THOUGH THE REMAINDER OF THE AFTERNOON BUT IT WILL BE
MINIMAL AND LOW LEVEL ADVECTIVE PROCESSES WILL HAVE TO CONTRIBUTE
TONIGHT AND COMBINE WITH THE STEEP LAPSE RATES THAT STILL REMAIN IN
PLACE VIS THE 18Z SGF/TOP SOUNDINGS.  THE ANTICIPATION IS STILL THAT
SCATTERED CONVECTION WILL DEVELOP ALONG THE COLD FRONT LATER THIS
AFTERNOON INTO EARLY EVENING ACROSS WRN MO AND SE KS ONCE THE CAP IS
BROKEN WHERE THE BEST SFC BASED INSTABILITY RESIDES...AND THIS
ACTIVITY SHOULD GROW UPSCALE INTO SEVERAL LINES OR CLUSTERS AS THEY
MOVE EASTWARD IN ASSOCIATION WITH DEEPENING LARGER SCALE ASCENT IN
TANDEM WITH THE MIGRATING COLD FRONT.  GIVEN THE STEEP LAPSE RATES I
STILL CANT RULE OUT ISOLD/SCT ELEVATED STORMS WELL AHEAD OF THE
COLD FRONT BUT DONT THINK THIS WILL REALLY BE THE MAIN PLAYER TNGT.
THE SEVERE WEATHER THREAT ISNT VERY CLEAR.  ANY ELEVATED STORMS
COULD PRODUCE SOME HAIL BUT OTHER THAN THAT THE BEST SEVERE
POTENTIAL WOULD APPEAR TO BE CONFINED TO CENTRAL MO THIS
EVENING...WITH A MORE ISOLD THREAT ACROSS THE REMAINDER OF THE
AREA.

THE FRONT SHOULD RESIDE FROM CENTRAL IL INTO SE MO AT DAYBREAK ON
WEDENSDAY WITH AN ATTENDANT THREAT OF RESIDUAL SHOWERS AND
THUNDERSTORMS MAINLY IN THE MORNING HOURS.  BY AFTERNOON THE FRONT
SHOULD BE SETTLING SOUTH/SOUTHEAST WITH WEAK HIGH PRESSURE SLIDING
INTO THE MID MS VLY.

ATTENTION THEN TURNS TO THE UPR LOW/TROF IN THE SRN STREAM PRESENTLY
INVOF OF THE DESERT SOUTHWEST.  THE MODELS ARE ALL IN AGREEMENT THAT
A SFC LOW WILL DEVELOP ON THE WRN EXTENSION OF THE FRONT ACROSS THE
SRN PLAINS WED NGT...WITH THE SFC LOW TRACKING NEWD ACROSS THE
LOWER MS VLY ON THURS AND INTO THE OH VLY BY FRIDAY MORNING. IN
RESPONSE TO THE LARGE SCALE ASCENT WITH THE TROF/LOW AND MID
LEVEL FRONTOGENETIC FORCING...A SIZEABLE SHIELD OF DEFORMATION
ZONE PRECIPITATION SHOULD EVOLVE. THE TIMING...ONSET...AND NRN
EXTENT OF THE PCPN ARE THE BIGGEST UNCERTAINTIES AND WHERE THE
MODELS DIFFER. THE GFS IS THE FASTEST AND FURTHEST NORTH AND ATTM
HAS BEEN TONED DOWN A BIT IN FAVOR OF THE NAM AND LATEST SREF. IN
THIS SCENARIO I EXPECT A SHIELD OF RAIN TO JUST BE SPREADING INTO
CENTRAL AND SE MO IN THE PREDAWN HOURS ON THURSDAY...AND MOVE NEWD
ENCOMPASSING MUCH OF THE SRN 2/3RDS OF THE CWA DURING THE DAY. THE
CLOUDS AND RAIN WILL MAKE FOR A COOL DAY WITH TEMPS ONCE AGAIN
WELL BLO NORMAL.

IN THE EXTENDED WE ARE STILL LOOKING AT A WEST COAST RIDGE
DOMINATING AND AN ERN U.S. TROF.  THE POSITION AND DEPTH OF THE ERN
TROF REMAINS UP IN THE AIR AND THE GUIDANCE HAS GENERALLY BEEN
SHOWING MORE NWLY FLOW ALOFT THAN NLY AND A TREND TOWARDS SLIGHTLY
WARMER TEMPERATURES.  I FOLLOWED SUITE IN THIS REGARDS.  THERE CUD
BE SOME SCT SHRA IMPACTING PORTIONS OF THE AREA SAT AND BEYOND BUT
THE PSN AND YO-YOING MODEL FCSTS LEAD TO VERY LIMITED CONFIDENCE AND
THEREFORE HAVE LEFT THE FCST DRY.
