AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
304 PM CST FRI APR 4 2003

ONCE CONVECTION CLEARS EAST OF THE AREA BY EARLY EVENING...MAIN
SHORT TERM FORECAST DILEMMA IS POSSIBLE FROST TONIGHT IN THE VERY
COLD AIR BEHIND THE FRONT. IN LATER PERIODS...THE TIMING OF
PRECIPITATION LATE SATURDAY NIGHT AND SUNDAY AND THEN COLD WEATHER
BEHIND THAT SYSTEM BECOME THE MAIN CONCERNS.

CONVECTION HAVING A TOUGH TIME TO GET GOING SO FAR. IN SOUTHERN
MO...STRONG CAP NOTED ON THE 18Z SGF SOUNDING AT AROUND 800MB...AND
ISOLATED HIGH BASED STORMS HAVE DEVELOPED IN THE LOCAL AREA...BUT
MOST GETTING SHEARED APART. CONVERGENCE RIGHT ALONG THE FRONT IS
LIMITED WITH VEERED SOUTHWEST WIND. OVERALL...BETTER CHANCES FOR
SEVERE WILL BE IN THE NORTHEASTERN PORTION OF THE FORECAST AREA
WHERE CAP IS WEAKER OR NON EXISTENT. UNIDIRECTIONAL WIND PROFILE AND
HIGH STORM BASES WILL LIMIT TORNADO PROBABILITIES...BUT HAIL AND
DAMAGING WINDS A THREAT WITH ANY STORMS THAT CAN GO SEVERE.

EXTENSIVE LOW CLOUDS BEHIND THE FRONT OVER EASTERN KS AND
NORTHWESTERN MO WILL MOVE INTO THE AREA LATE THIS AFTERNOON AND THIS
EVENING. ETA LOW LEVEL MOISTURE PROGS BECOME FAIRLY DRY AFTER
MIDNIGHT...AND WITH LIGHT WINDS UNDER WEAK SURFACE RIDGE BUILDING
INTO THE AREA...AREAS OF FROST WILL BE POSSIBLE. STILL ON THE FENCE
ABOUT A FROST ADVISORY...BUT WILL MENTION FROST IN PUBLIC FORECAST
TEXT EITHER WAY I DECIDE TO GO.

NEXT SYSTEM STILL ON TRACK FOR SUNDAY...AND HAVE NOT MADE MANY
CHANGES. STORMS DEVELOP ALONG THE RED RIVER LATE SATURDAY THEN LIFT
NORTHEAST AS A STORM COMPLEX SATURDAY NIGHT. LOW CENTER WILL MOVE
EAST ALONG THE OK/KS LINE SUNDAY WITH WARM FRONT MAKING IT AS FAR
NORTH AS THE ARKANSAS STATE LINE SUNDAY AFTERNOON. SURFACE BASED
CONVECTION WILL REMAIN SOUTH OF THE WARM FRONT...BUT RAIN WITH
EMBEDDED STORMS WILL BE LIKELY ON LATE SAT AND SUN. LARGE HAIL WILL
BE POSSIBLE WITH SEVERE STORMS LATE SAT NIGHT AND SUN. COLD AIR WILL
MOVE INTO THE AREA IN THE WAKE OF THIS SYSTEM WITH A COUPLE OF
NIGHTS OF FROST OR FREEZE POSSIBLE MON NIGHT/TUE MORNING AND TUE
NIGHT AND WED MORNING.

HAZARDOUS WEATHER OUTLOOK
NATIONAL WEATHER SERVICE SPRINGFIELD MO
105 PM CST FRI APR 4 2003

THIS HAZARDOUS WEATHER OUTLOOK IS FOR THE MISSOURI OZARKS AND EXTREME
SOUTHEAST KANSAS.

.DAY ONE...THIS AFTERNOON AND TONIGHT.

  WEATHER HAZARDS EXPECTED:

  SEVERE THUNDERSTORMS...MAIN HAZARDS LARGE HAIL AND DAMAGING WINDS.

  AREAS AFFECTED AND TIMING:

ALL OF CENTRAL AND SOUTHERN MISSOURI EAST OF A COLD FRONT THAT
EXTENDS FROM OSCEOLA TO JOPLIN. COUNTIES ALONG AND NORTH OF A LINE
FROM GREENFIELD TO ROLLA WILL HAVE THE BEST CHANCE FOR SEVERE
THUNDERSTORMS WHERE THE ATMOSPHERE IS EITHER NOT CAPPED OR JUST
WEAKLY CAPPED.

  DISCUSSION:

A STRONG COLD FRONT WILL MOVE EAST THROUGH THE REGION THIS
AFTERNOON. THE ATMOSPHERE IS CAPPED OVER SOUTHERN MISSOURI EARLY
THIS AFTERNOON...BUT IN CENTRAL MISSOURI THE AREAS IS ONLY WEAKLY
CAPPED. ISOLATED SHOWERS HAVE ALREADY BEGUN TO DEVELOP ALONG THE
FRONT FROM WARSAW TO JUST NORTH OF CASSVILLE. DAYTIME HEATING WILL
FURTHER ERODE THE CAP THIS AFTERNOON ALLOWING STRONG TO SEVERE
STORMS TO DEVELOP. GIVEN THE THERMODYNAMIC AND WIND
PROFILES...SUPERCELLS WITH DAMAGING WIND AND LARGE HAIL WILL BE
POSSIBLE WITH THESE STORMS. WHILE AN ISOLATED TORNADO CANNOT BE
RULED OUT...DEWPOINT DEPRESSIONS OF 20 DEGREES WILL NOT BE CONDUCIVE
TO OVERALL TORNADO DEVELOPMENT.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY.

THUNDERSTORMS WILL DEVELOP IN THE SOUTHERN PLAINS LATE SATURDAY
AHEAD OF ANOTHER STORM SYSTEM. THE STORMS WILL DEVELOP INTO A
COMPLEX OF STORMS ALONG A WARM FRONT AND MOVE NORTHWARD INTO
SOUTHWEST MISSOURI LATE SATURDAY NIGHT AND INTO THE ENTIRE AREA ON
SUNDAY. SOME OF THE STORMS WILL HAVE THE POTENTIAL TO PRODUCE LARGE
HAIL.

COLD AIR WILL MOVE INTO THE AREA EARLY NEXT WEEK AND NIGHTTIME
TEMPERATURES WILL FALL TO THE UPPER 20S AND LOWER 30S IN MANY AREAS
EARLY TUESDAY AND WEDNESDAY MORNINGS.

.SPOTTER INFORMATION STATEMENT...
