AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
306 AM CDT FRI JUN 01 2007

.DISCUSSION...
SEVERAL FORECAST CHALLENGES EXISTED IN TODAYS ANALYSIS.  A LARGE
COMPLEX OF CONVECTION WILL SWEEP ACROSS THE CWA THIS
MORNING...AND TODAYS WEATHER WILL BE DEPENDENT UPON HOW THIS SYSTEM
EVOLVES WITH TIME.  A 35 - 50 KNOT LOW LEVEL JET CONTINUES TO PUMP
COPIOUS AMOUNTS OF MOISTURE TRANSPORT INTO THE SYSTEM.

WITH THE WELL ESTABLISHED COLD POOL MY INITIAL THINKING IS THAT GOOD
AREAL COVERAGE IN MEASURABLE RAIN WILL OCCUR THROUGH THE MORNING
HOURS.  THERE ARE ALSO SOME INDICATIONS ON RADAR THAT A VORTICITY
CENTER HAS DEVELOPED WITHIN THE COMPLEX...WHICH WILL ALSO BE A
FOCUSING MECHANISM FOR CONVECTION TODAY AS IT TRACKS INTO SOUTHERN
MISSOURI.  HAVE YET TO DECIDE HOW WE WILL FOCUS POPS...SO THIS WILL
BE A LAST MINUTE DECISION JUST PRIOR TO PACKAGE ISSUANCE TIME.

THE KANSAS COLD FRONT FINALLY PUSHES INTO SOUTHWEST MISSOURI
SATURDAY NIGHT...THEREFORE A VERY MOIST AND SOMEWHAT UNSTABLE
AIRMASS WILL BE ANCHORED OVER THE CWA THROUGH SATURDAY.  THIS ZONE
OF BAROCLINICITY WILL BE A FOCUS FOR CONVECTION IN JUST ABOUT EVERY
FORECAST PERIOD.  THE LOW LEVEL AIRMASS FINALLY BEGINS TO DRY OUT
SOME BY SUNDAY AS THE FRONT PUSHES SOUTH OF THE CWA.
HOWEVER...MODELS INDICATE SEVERAL SHORTWAVES MIGRATING THROUGH THE
NORTHWEST FLOW...WHICH WILL CAUSE PERIODS OF LIFT AND POSSIBLE RAIN
INTO NEXT WORK WEEK.  WHILE RAIN CHANCES WILL DECREASE...I CAN NOT
COMPLETELY RULE THEM OUT...THEREFORE WILL HAVE AT LEAST A SLIGHT
CHANCE GOING WITHIN THE GRIDS THROUGH WEDNESDAY.

TEMPERATURES IN THE SHORT TERM WERE EXTREMELY CHALLENGING...AND WILL
BE DEPENDENT UPON CLOUD COVER AND PRECIPITATION.  LARGE DIFFERENCES
EXISTED BETWEEN THE MAV AND MET GUIDANCE IN THIS AFTERNOONS MAX
READINGS.  NOT COMPLETELY KNOWING HOW TODAYS CONVECTIVE COMPLEX WILL
EVOLVE...I TOOK A COMPROMISE BETWEEN THE TWO GUIDANCES.  THE REST OF
THE PERIODS I LEANED TOWARD THE WARMER MAV GUIDANCE.  WOULD THINK
THAT EVEN THE MAV MOS IS TOO COOL WITH OVERNIGHT LOWS THROUGH
SATURDAY NIGHT.  WITH THE MOIST AIRMASS...CLOUDS...AND
PRECIP...OVERNIGHT READINGS MAY HANG IN THE UPPER 60S.

.AVIATION...
THUNDERSTORMS ACROSS KANSAS AND NORTHERN OKLAHOMA WILL SPREAD EAST
INTO SOUTHWEST MISSOURI DURING THE EARLY MORNING HOURS. THE STORMS
WILL LIKELY REACH JOPLIN AROUND 09Z AND SPRINGFIELD AROUND 11Z.
GUSTY WINDS IN EXCESS OF 30 KTS AND MVFR VISIBILITIES AND CEILINGS
WILL LIKELY ACCOMPANY THE CONVECTION. UNCERTAINTY INCREASES WITH
TIME TO THE CONVERGE AND DURATION OF THE STORMS AND INCLUDED THUNDER
IN THE VICINITY THROUGH THE PERIOD. WHILE THE CAVITY WILL DECREASE
FRIDAY MORNING...ADDITIONAL DEVELOPMENT WILL BE POSSIBLE THROUGH THE
DAY FRIDAY.
