AREA FORECAST DISCUSSION...UPDATED AVIATION
NATIONAL WEATHER SERVICE ST LOUIS MO
1138 PM CDT SUN MAR 21 2010

.DISCUSSION...
/235 PM CDT SUN MAR 21 2010/

MAIN CHALLENGE INITIALLY DEALS WITH WHEN PRECIPITATION WILL EXIT THE
AREA.  THERE IS GOOD AGREEMENT AMONGST THE MODELS THAT THE UPPER LOW
CURRENTLY ALONG THE AR/LA BORDER WILL LIFT NEWD INTO ERN TENNESSEE
BY LATE MONDAY.  THIS WILL CAUSE THE DEFORMATION ZONE RAIN THAT
CURRENTLY COVERS THE SERN HALF OF THE CWA TO SLOWLY END FROM WEST TO
EAST OVER THE NEXT 24 HOURS.  WILL HAVE A SHARP POP GRADIENT ON THE
NRN EDGE OF THE DEFORMATION AND WILL KEEP CATEGORICAL POPS THIS
EVENING BASICALLY WHERE IT IS RAINING NOW WITH DRY POPS GOING FROM
COU NEWD INTO UIN...AND THEN SHIFT IT SLIGHTLY EWD OVERNIGHT.  KEPT
CHANCE POPS GOING OVER SWRN AND S CNTRL IL ON MONDAY MORNING BEFORE
ENDING IT BY AFTERNOON. FORECAST SOUNDINGS ARE SHOWING THE LOW LEVEL
THERMAL PROFILES WILL REMAIN ABOVE FREEZING UNTIL THE PRECIPITATION
ENDS. AREA WILL LIE UNDER LARGE SCALE SUBSIDENCE AS RIDGING BUILDS
IN BEHIND THE UPPER LOW...SO HAVE DRY WEATHER GOING THROUGH
WEDNESDAY.

WENT TOWARD THE COOLER NAM MOS FOR HIGHS TOMORROW WHICH IS SUPPORTED
BY MIXING DOWN 925MB TEMPS FROM BOTH THE NAM/GFS. CNTRL MO MAY BE
INHIBITED A BIT BY WRN MO SNOW PACK AND CLOUDS WILL TAKE A WHILE
TO CLEAR IN THE EAST. MOSTLY SUNNY SKIES AND SWLY WINDS AHEAD OF A
COLD FRONT JUSTIFY THE WARMER GFS MOS TEMPS ON TUESDAY.

TWO STORM SYSTEMS WILL BRING PRECIPITATION TO THE AREA ON
WEDNESDAY NIGHT INTO THURSDAY NIGHT...AND THEN AGAIN SATURDAY
NIGHT AND NEXT SUNDAY. WHILE THERE IS SOME CONTINUITY ISSUES
WITHIN THE INDIVIDUAL MEDIUM RANGE MODELS...THEY ARE SHOWING
DECENT AGREEMENT WITH THE TIMING OF BOTH SYSTEMS. SOUNDINGS AND
FORECAST SURFACE TEMPERATURES STILL SUGGEST THERE WILL BE NO
FREEZING/FROZEN PRECIP WITH THESE LATE MARCH SYSTEMS AND DO NOT
SEE ENOUGH INSTABILITY OR LOW LEVEL MOISTURE TO INCLUDE THUNDER AT
THIS TIME.
