AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
236 AM CDT SAT MAY 25 2013

.SHORT TERM...(TODAY THROUGH SUNDAY)
ISSUED AT 233 AM CDT SAT MAY 25 2013

HIGH PRESSURE CONTINUES TO PULL EAST ACROSS THE GREAT LAKES AND OHIO
VALLEY THIS MORNING...WITH SOUTHERLY FLOW INCREASING ACROSS THE
REGION IN RESPONSE...ESPECIALLY OVER THE WESTERN HALF OR SO OF THE
CWA.  THIS INCREASE IN LOW LEVEL FLOW/WAA HAS RESULTED IN RATHER
MILD CONDITIONS FOR WESTERN MISSOURI AND SOUTHEASTERN KANSAS...WITH
READINGS ONLY DROPPING TO THE LOW TO MID 60S AS OF 2 AM.  FURTHER
EAST...WHERE HIGH PRESSURE REMAINS THE DOMINATE FEATURE...MORNING
LOWS DROPPED INTO THE 40S.

ANOTHER WARM AND OVERALL PLEASANT DAY IS EXPECTED ACROSS THE REGION
TODAY...AS HIGH TEMPERATURES WARM INTO THE LOW 80S. MOST LOCATIONS
LOOK TO REMAIN DRY...BUT A FEW ISOLATED THUNDERSTORMS MAY DEVELOP
DURING THE DAY TODAY.  THE BEST POTENTIAL FOR ISOLATED TO SCATTERED
STORMS WILL BE ACROSS CENTRAL MISSOURI...WHERE THE CONVECTIVE
REMNANTS/MCV ASSOCIATED WITH ELEVATED CONVECTION CURRENTLY OVER
EASTERN NEBRASKA/WESTERN IOWA MAY CLIP THE AREA.  AGAIN
THOUGH...MOST PLACES SHOULD REMAIN DRY.

A FEW SCATTERED STORMS WILL REMAIN POSSIBLE OVER CENTRAL MISSOURI
TONIGHT...BEFORE MORE WIDESPREAD THUNDERSTORM POTENTIAL DEVELOPS FOR
SUNDAY.  THE CONVECTIVE SCENARIO FOR SUNDAY IS SOMEWHAT COMPLEX...AS
TWO DISTINCT FEATURES WILL BE IN PLAY.  THE FIRST WILL BE THE
POTENTIAL FOR A MCV TO DROP SOUTH FROM NORTHERN KANSAS/SOUTHERN
NEBRASKA DURING THE DAYTIME HOURS SUNDAY.  WHILE MODEL GUIDANCE IS
IN SURPRISINGLY GOOD AGREEMENT REGARDING THIS FEATURE...SUCH
MCS-INDUCED FEATURES ARE NOTORIOUSLY FICKLE IN "MODEL WORLD".  THE
OTHER FEATURE OF NOTE WILL BE THE BROAD SUBTROPICAL VORT THAT HAS
BEEN MOVING SLOWLY ACROSS TEXAS THE LAST DAY OR TWO.  IT IS PROGGED
TO MOVE EAST-NORTHEAST WITH TIME INTO ARKANSAS...AND THE RESULTING
INCREASE IN MOISTURE AND LIFT WITH THIS VORT SHOULD BE ENOUGH TO SET
OFF SCATTERED STORMS DURING THE DAY SUNDAY.  STILL DON`T THINK
RAINFALL WILL BE WIDESPREAD ENOUGH TO WASH OUT MOST HOLIDAY WEEKEND
PLANS...BUT ANYONE WITH OUTDOOR PLANS SHOULD REMAIN AWARE OF THE
RAIN/LIGHTNING RISK.

.LONG TERM...(MONDAY THROUGH FRIDAY)
ISSUED AT 233 AM CDT SAT MAY 25 2013

TEMPERATURES SUNDAY AND AGAIN MONDAY WILL BE IN THE LOW TO MID
80S...JUST A FEW DEGREES ABOVE NORMAL FOR THIS TIME OF YEAR.  AS THE
MAIN UPPER LEVEL RIDGE AXIS LIFTS A BIT NORTHEAST ON
MONDAY...THUNDERSTORM CHANCES SHOULD DECREASE AS THE POTENTIAL IS
SHUNTED TO THE NORTH OF THE FORECAST AREA.

A SEVERAL DAY LONG STRETCH OF GENERALLY DRY AND SEASONABLY WARM
WEATHER IS EXPECTED FOR THE FIRST FEW DAYS OF THE SHORTENED
WORKWEEK...AS SOUTHWEST FLOW IS ESTABLISHED OVER MUCH OF THE
NATION`S MID SECTION.  DESPITE AN INCREASE IN LOW LEVEL
MOISTURE...CAPPING ALOFT WILL LIMIT THUNDERSTORM POTENTIAL.

THE NEXT CHANCE OF WIDESPREAD RAINFALL LOOKS TO ARRIVE IN THE DAY
6/7 TIMEFRAME...AS THE WESTERN TROUGH BEGINS TO TRANSLATE EAST AND
HEIGHT FALLS START TO OVERSPREAD THE REGION.  SOME SIGNIFICANT
DIFFERENCES REMAIN AMONG THE VARIOUS MEMBERS OF THE EXTENDED
GUIDANCE SUITE...ESPECIALLY WITH THE STRENGTH/TIMING OF VARIOUS
SHORTWAVES AND ASSOCIATED FRONTAL BOUNDARIES.  THAT SAID...THERE
DOES SEEM TO BE BROAD AGREEMENT IN A RELATIVELY ACTIVE END TO THE
MONTH OF MAY AND START TO JUNE...WITH SEVERAL CHANCES FOR RAIN
HEADING INTO NEXT WEEKEND.
