AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
114 PM CDT SAT MAY 23 2009

...UPDATE TO PUBLIC AND AVIATION...

.UPDATE...

A BAND OF SHOWERS AND THUNDERSTORMS CONTINUES TO SLOWLY PUSH
NORTHWEST ACROSS THE INTERSTATE 44 CORRIDOR EARLY THIS AFTERNOON.
OTHER THUNDERSTORMS ARE BEGINNING TO DEVELOP ELSEWHERE ACROSS THE
OZARKS AS CONVECTIVE TEMPERATURES ARE BEING REACHED. THE MOST
EFFICIENT OF UPDRAFTS ARE PRODUCING SMALL HAIL. RADAR AND SURFACE
OBSERVATIONS HAVE ALSO INDICATED WEAK DOWNBURST SIGNATURES...WITH
WIND GUSTS GENERALLY BELOW 40 MPH. THE BIGGEST CONCERN NOW AND FOR
THE REMAINDER OF THE AFTERNOON WILL BE THE THREAT FOR HEAVY
RAINFALL AND LOCALIZED FLOODING. THE RECENT STORMS OVER
SPRINGFIELD ARE PRODUCING RAINFALL RATES NEARING TWO INCHES PER
HOUR...WHICH IS CONCERNING GIVEN THE SLOW NORTHWESTWARD DRIFT OF
THE STORMS. WILL BE MONITORING CLOSELY FOR REGENERATION OF STORMS
OVER THE SAME AREAS AS OUTFLOW INTERACTS WITH THE WEAK AMBIENT
HORIZONTAL SHEAR.

.DISCUSSION...

THE FOCUS OF THE FORECAST IS ON CHANCES FOR THUNDERSTORMS THROUGH
THE HOLIDAY WEEKEND INTO EARLY NEXT WEEK.

WATER VAPOR IMAGERY SHOWS AN UPPER LEVEL LOW TRACKING NORTHWEST
INTO THE MISSISSIPPI DELTA REGION. SHOWERS AND THUNDERSTORMS HAVE
DEVELOPED OVERNIGHT ACROSS SOUTHERN ARKANSAS ASSOCIATED WITH
DEEPER GULF MOISTURE RETURN. THE UPPER LEVEL LOW WILL CONTINUE TO
TRANSPORT GULF MOISTURE NORTH INTO THE PLAINS AND THE OZARKS WITH
EAST SOUTHEAST FLOW ALOFT. TODAY SCATTERED THUNDERSTORM
DEVELOPMENT WILL FAVOR THE AFTERNOON AND EARLY EVENING HOURS
AIDED BY DAYTIME HEATING WITH A WEAKLY CAPPED ATMOSPHERE.

THE UPPER LEVEL LOW WILL MOVE THROUGH THE LOWER MISSISSIPPI
VALLEY OVER THE HOLIDAY WEEKEND. MODEL CONSENSUS IS FOR THE LOW
TO PROPAGATE THROUGH ARKANSAS SUNDAY AND THEN MIGRATE NORTHEAST
THROUGH MISSOURI MONDAY WITH THE REMNANT LOW PHASING WITH THE
WESTERLIES ACROSS THE MIDWEST TUESDAY AND WEDNESDAY.

SHOWERS AND THUNDERSTORMS ARE EXPECTED TO BECOME MORE NUMEROUS
ACROSS SOUTHWEST MISSOURI AND SOUTHEAST KANSAS SUNDAY AND MONDAY
AS LIFT INCREASES WITH THE PASSAGE OF THE LOW. SCATTERED SHOWERS
AND THUNDERSTORMS COULD PERSIST SUNDAY NIGHT AND MONDAY AS A
RESULT. MONDAY WILL LIKELY BE THE COOLEST DAY OF THE HOLIDAY
WEEKEND DUE TO WIDESPREAD CLOUD COVER KEEPING HIGH TEMPERATURES
IN THE MID 70S. OTHERWISE...HIGHS NEAR 80 AND LOWS NEAR 60 ARE
ANTICIPATED.

DUE TO LIMITED INSTABILITY AND WEAK SHEAR THE POTENTIAL OF SEVERE
THUNDERSTORMS OVER THE HOLIDAY WEEKEND REMAINS LOW. HOWEVER WITH
PRECIPITABLE WATER VALUES NEAR AN INCH AND A HALF ACROSS THE
REGION...LOCALLY HEAVY RAINFALL COULD POTENTIALLY LEAD TO
LOCALIZED FLASH FLOODING WHERE STRONGER THUNDERSTORM UPDRAFTS
DEVELOP AND WHERE THUNDERSTORMS TRAIN ALONG RESIDUAL OUTFLOW
BOUNDARIES.

SLIGHT CHANCES FOR SHOWERS AND THUNDERSTORMS CONTINUE INTO THE
MIDDLE OF NEXT WEEK WITH RESIDUAL MOISTURE AND WEAK DISTURBANCES
MOVING THROUGH NORTHWEST FLOW ALOFT. HOWEVER COVERAGE IS EXPECTED
TO BE ISOLATED TO SCATTERED AND PRIMARILY DIURNALLY DRIVEN.

.AVIATION...

THUNDERSTORMS CONTINUE EARLY THIS AFTERNOON IN THE VICINITY OF
KSGF AND ARE APPROACHING KJLN FROM THE EAST. THESE STORMS WILL
REMAIN SCATTERED ACROSS SOUTHWEST MISSOURI FOR THE REMAINDER OF
THIS AFTERNOON AND DIMINISH EARLY THIS EVENING. EXPECT MVFR
CEILINGS AND VISIBILITIES WITH THESE STORMS...WITH BRIEF
REDUCTIONS TO IFR VISIBILITIES. WE MAY THEN SEE SOME LIGHT FOG
DEVELOP LATER TONIGHT WITH MORE STORMS EXPECTED STARTING AROUND
MID MORNING ON SUNDAY.
