AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
235 PM CDT TUE JUN 4 2002

PRIMARY FORECAST CONCERN WILL BE FLOODING POTENTIAL TONIGHT AND
WEDNESDAY.

CONVECTION NUDGING ITS WAY SOUTHEASTWARD ALONG AND BEHIND A SAGGING
COLD FRONT THAT STRETCHED FROM NEAR MOLINE IL TO CHANUTE KS. WATER
VAPOR SHOWS A WELL DEFINED TROUGH PUSHING ACROSS THE ROCKIES WITH
A SHORTWAVE EJECTING NORTHEAST ACROSS THE OKLAHOMA PANHANDLE.  RUC
SHOWS UPPER DIVERGENCE INCREASING AHEAD OF THIS IMPULSE AND RADAR
GIVES EVIDENCE OF THIS AS WELL. ISOLATED STORMS HAVE FORMED ACROSS
SOUTHERN MISSOURI IN TROPICAL LIKE AIRMASS. PLENTY OF MOISTURE
POOLING AHEAD OF THE FRONT WITH SURFACE DEWPOINTS NEAR 70 ACROSS THE
OZARKS.  LAPS SOUNDING OVER SPRINGFIELD SHOWED CAPES OF 3800 J/KG
AND A LIFTED INDEX OF -8.

THE FRONT WILL ONLY DRIFT SLOWLY SOUTHEAST TONIGHT AS UPPER FLOW
BACKS IN ADVANCE OF THE APPROACHING TROUGH.  I AM CONCERNED ABOUT
FLOOD POTENTIAL ACROSS MUCH OF THE AREA BUT ESPECIALLY SOUTHWEST
MISSOURI AND FAR SOUTHEAST KANSAS TONIGHT THROUGH WEDNESDAY
MORNING.  GOOD LOW LEVEL MOISTURE CONVERGENCE...PERSISTENT UPPER
LEVEL DIVERGENCE ...850 MB DEWPOINTS NEAR 15 DEGREES...PRECIPITABLE
WATER VALUES NEAR 2 INCHES...AND A SLOW MOVING FRONT ALL SUPPORT
HEAVY RAIN POTENTIAL. WILL ISSUE A FLOOD WATCH FOR ALL BUT SOUTH
CENTRAL MISSOURI.  ISOLATED SEVERE STORMS WITH LARGE HAIL POSSIBLE
BEHIND THE FRONT AND PERHAPS A WET MICROBURST ALONG THE FRONT...BUT
OVERALL SEVERE RISK LOOKS LOW.

ONGOING CONVECTION WILL CONTINUE THROUGH WEDNESDAY MORNING AND
GRADUALLY SHIFT SOUTHWARD. MOST OF THE RAIN DURING THE AFTERNOON
SHOULD BE FOCUSED SOUTH OF I-44.  HEAVY RAINFALL THREAT WILL SPREAD
INTO SOUTH CENTRAL MISSOURI BUT INTENSITY OF CONVECTION IS IN
QUESTION.  CLOUDS...SHOWERS...AND A NORTHEAST WIND WILL BRING A
SIGNIFICANTLY COOLER DAY.

LESS HUMID AIRMASS WILL MAKES ITS WAY INTO THE REGION BY THURSDAY AS
THE SURFACE HIGH BUILDS OVER THE AREA. A WARMING TREND WILL BEGIN
FRIDAY AND CONTINUE INTO THE WEEKEND.  STILL UNCERTAINTY WITH
PROGRESSION OF THE NEXT TROUGH AND ASSOCIATED FRONT.  WILL CONTINUE
