AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE LITTLE ROCK AR
221 PM CDT TUE MAY 6 2003

.SHORT TERM...MESO ETA HAS BEEN THE BEST MODEL OF LATE DEALING WITH
THIS PROLONGED STRETCH OF CONVECTIVE WEATHER. REALLY SEE NO REASON
TO DEVIATE AT THIS POINT. OTHER MODELS IN CLOSE ENOUGH AGREEMENT
THAT A BLENDS OF SOLUTIONS IS PREFERRED.

LATEST SURFACE ANALYSIS SHOWS WARM FRONT OVER CENTRAL MISSOURI
MOVING NORTH AND LOW PRESSURE OVER NORTH CENTRAL OKLAHOMA. DRY LINE
LOCATED OVER EAST CENTRAL OKLAHOMA. AIR MASS CONTINUES TO BE PRIMED
FOR CONVECTION WITH THE DRY LINE THE TRIGGER. COPIOUS LOW LEVEL
MOISTURE AND IMPRESSIVE CAPE IN PLACE.... FAVORABLE JET DYNAMICS
ALSO IN THE MIX. ANOTHER ROUND OF SEVERE WEATHER LIKELY ACROSS THE
CWA TONIGHT. 18Z LAUNCH SHOWS SIGNIFICANT CAP OVER THE AREA WHICH
WILL DELAY CONVECTION WHICH ONLY CONFIRMS EARLIER SUSPICION THE
EVENT WILL BE LATE IN THE DAY/OVERNIGHT.

CONVECTION SHOULD CONTINUE MOST OF THE NIGHT BEFORE RELAXING A BIT
WEDNESDAY. BREAK WILL BE BRIEF AS MID LEVEL TROUGH WILL REMAIN OVER
THE WESTERN THIRD OF THE NATION AND TROUGH WILL CONTINUE TO EJECT
SHORTWAVES.  QUASI STATIONARY FRONT WILL REMAIN ACROSS THE NORTH
WITH SOUPY AIRMASS REMAINING IN PLACE. CONVECTION LIKELY ONCE AGAIN
BUT WIDESPREAD SEVERE IS NOT EXPECTED WITH THE BEST CHANCES OF
SEEING SEVERE WEATHER OVER THE CENTRAL AND NORTH. QUIET WEATHER
FINALLY RETURNS TO THE CWA ON FRIDAY BUT STILL CARRY SLIGHT CHANCE
POPS AS ENOUGH RESIDUAL MOISTURE WILL BE AROUND WITH NUMEROUS
BOUNDARIES STILL LURKING.  WENT WITH A BLEND OF FWC/MAV NUMBERS
THROUGHOUT.

.EXTENDED...MODELS IN DECENT AGREEMENT IN THE MEDIUM RANGE WITH
REGARDS TO DEVELOPING LOW FOR THE EARLY PART OF THE WEEKEND.
DIFFERENCES DO EXIST BETWEEN THE MODELS SO A BLEND OF SOLUTIONS IS
PREFERRED WITH A LEAN TOWARDS THE GFS. PACIFIC ENERGY CRASHES ON
SHORE AND DIVES INTO THE GREAT BASIN CARVING OUT A DEEP UPPER LOW.
LOW MOVES EASTWARD THROUGH THE PLAINS REACHING THE GREAT LAKES BY
SUNDAY EVENING. SURFACE REFLECTION LOCATED IN CENTRAL NEBRASKA
SATURDAY MORNING WITH TRAILING COLD FRONT INTO WESTERN TEXAS. LOW
MOVES OFF TO THE NORTHWEST AND FRONT MOVES THROUGH CWA SATURDAY AND
SATURDAY NIGHT. DYNAMICS AND MOISTURE NOT TERRIBLY IMPRESSIVE WITH
THIS SYSTEM BUT SCATTERED SHOWERS AND THUNDERSTORMS ARE WARRANTED.
HIGH PRESSURE FINALLY BUILDS IN FOR EARLY NEXT WEEK FOR COOLER AND
DRIER WEATHER OVER THE CWA. ENOUGH MOISTURE WILL BE AROUND FOR
PARTLY CLOUDY CONDITIONS.
