Hail in Missouri, April 6, 2003

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
125 AM CST SUN APR 6 2003

FORECAST CONCERNS: INTENSITY/LONGEVITY OF INITIAL RAINFALL THIS
MORNING. CHANCE OF STRONG/SEVERE STORMS OVER EXTREME SOUTHERN
MISSOURI SUNDAY AFTERNOON.

REGION RADAR SHOWING INCREASING SHOWERS AND THUNDERSTORMS OVER
SOUTHEAST KANSAS AND THE WESTERN 1/2 OF FORECAST AREA SINCE 11 PM.
THIS IS RIGHT ON TARGET AS PREVIOUSLY ADVERTISED AND WITH
INTENSIFYING LOW LEVEL JET AND UPPER LEVEL JET ENERGY MOVING OVER
THE REGION DURING THE NEXT 6 TO 12 HOURS...EXPECT THE CONTINUATION
OF SHOWERS AND THUNDERSTORMS THROUGHOUT THE AREA.

INITIALLY DRY LOW LEVELS NEAR THE SURFACE WILL PRECLUDE SOME OF THE
HEAVIEST RAINFALL IN SOUTH CENTRAL MISSOURI UNTIL AROUND DAWN AS
MOISTURE FEED FROM THE SOUTH NEARLY SATURATES THE SOUNDINGS
THROUGHOUT THE AREA (ALSO NOSE OF LOW LEVEL JET IS MORE IN LINE FOR
SOUTHWEST MISSOURI THAN SOUTH CENTRAL). DUE TO A VERY LOW WET BULB
HEIGHT...NUMEROUS REPORTS OF PEA SIZE HAIL WERE OCCURRING ACROSS THE
OZARKS...ESPECIALLY WITH RADAR ECHOES LIFT ABOVE 10000 FEET. THIS
WILL LIKELY CONTINUE THROUGH THE EARLY MORNING HOURS BEFORE WET BULB
HEIGHTS RISE SLOWLY AS WARMER AIR ADVECTS NORTHWARD.

AS THE LOW LEVEL JET SHIFTS NORTHWARD THIS MORNING AND THE UPPER
LEVEL JET ENERGY MOVES EAST OF THE REGION...EXPECT AN OVERALL
DECREASE IN THE COVERAGE. HOWEVER RESIDUAL SHOWERS AND ISOLATED
THUNDERSTORMS WILL LIKELY CONTINUE THROUGH THE AFTERNOON (WEAK
OMAGES BETWEEN 70-50H). AS FOR SEVERE STORMS...SURFACE LOW AND WARM
SECTOR MAY REACH AS FAR NORTH AS EXTREME SOUTHWEST MISSOURI DURING
THE LATE AFTERNOON HOURS. CAPES INCREASE TO 1500 J/KG (NO CAP)
DURING THIS TIME...AND WITH WINDS VEERING FROM THE
SOUTHEAST...SURFACE BASED STORMS ARE POSSIBLE. WILL HIGHLIGHT HWO
THIS MORNING ON THIS POTENTIAL PROBLEM.

ANYWAY THE MAIN ENERGY SHIFTS NORTHWARD SUNDAY NIGHT WITH RESIDUAL
CLOUD COVER EXPECTED ON MONDAY. MODELS ARE ALSO HINTING ON
PRECIPITATION TUESDAY AS MAIN UPPER TROUGH MOVES THROUGH. WILL
CONTINUE DRY FORECAST...BUT MODELS HAVE BEEN CONSISTENT WITH THIS
FEATURE DURING THE LAST TWO RUNS. ALSO THICKNESSES ARE LOW ENOUGH
FOR A MIXTURE OF FROZEN PRECIPITATION EXTENDED PERIODS CONTINUE TO
LOOK DRY AS HIGH PRESSURE DOMINATES THE CENTRAL U.S. THROUGH LATE
WEEK. EXPECT A SLOW MODERATION OF TEMPERATURES DURING THIS PERIOD AS
THE AIR MASS REMAINS RELATIVITY COOL FOR THIS TIME OF YEAR.

FINAL ISC GRIDS WILL BE SENT BY 3 AM.
