AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LITTLE ROCK AR
342 AM CST WED FEB 29 2012

.SHORT TERM...TODAY THROUGH SATURDAY

THUNDERSTORMS ONGOING ACROSS NRN AND PORTIONS OF NRN AR THIS
MORNING ALONG THE COLD FRONT. THIS FRONT WILL CONTINUE ITS
PROGRESS TO THE SE THROUGH THIS AFTERNOON...WITH CHANCES FOR
SHOWERS AND THUNDERSTORMS PERSISTING ALONG AND JUST AHEAD OF THE
FRONT. EARLY THIS MORNING...THE BIGGEST THREAT FOR SVR STORMS HAS
BEEN ACROSS THE NRN AR OZARKS NEAR THE MO BORDER WHERE STORMS ARE
IN CLOSER PROXIMITY TO THE BEST FORCING LIFTING NORTH OF THE
STATE. BIGGEST THREAT SO FAR HAS BEEN DAMAGING WINDS...THOUGH MID
LEVEL MESOS HAVE BEEN NOTED OVER TIME. THIS HAS ENHANCE THE HAIL
THREAT OFF AN ON...BUT WIND CONTINUES TO BE THE MAIN THREAT. LOW
LEVEL WIND FIELDS HAVE PREVENTED STORMS FROM TIGHTENING MUCH NEAR
THE SFC...WITH OBS AHEAD OF THE LINE SHOWING SW WINDS.
HOWEVER...THE POTENTIAL DOES STILL REMAIN FOR AN ISOLATED TORNADO
THREAT...AND WILL CONTINUE TO MONITOR CLOSELY TO SEE IF THE
TIGHTER CIRCULATIONS CAN EXTEND FURTHER DOWNWARD. TORNADO WATCH
CONTINUES FOR MUCH OF THE NRN AND NERN AR COUNTIES.

THROUGH THIS AFTERNOON...BEST POPS WILL REMAIN NEAR AND AHEAD OF THE
FRONT AS IT PROGRESSES SE ACROSS THE STATE. SOME STORMS COULD
BECOME STRONG TO SVR...MAINLY ACROSS SERN SECTIONS OF THE STATE
WHERE THE BETTER INSTABILITY WOULD EXIST. DEEP LAYER SHR WILL BE
PLENTIFUL THAT STORMS COULD ROTATE ALOFT...WITH MAINLY A WIND AND
HAIL THREAT EXPECTED. THE LOW LEVEL SHEAR LOOKS LIMITED ENOUGH THAT
ONLY AN ISOLATED HAIL THREAT WOULD EXIST. AGAIN...THE BEST THREAT
FOR SVR WX THIS AFTERNOON WILL BE ACROSS THE SERN COUNTIES.

THE NEXT SYSTEM WILL IMPACT THE NATURAL STATE STARTING THU NIGHT AS
MOISTURE SURGES BACK NORTH FROM THE GULF. SHOWERS AND THUNDERSTORMS
WILL DEVELOP ALONG AND AHEAD OF A COLD FRONT THAT WILL SURGE SE
ACROSS THE STATE FRI AFTERNOON. MOISTURE LEVEL WILL BE HIGH
ENOUGH...WITH INSTABILITY AND SHR LEVELS ALSO HIGH ENOUGH TO WARRANT
A MENTION OF STRONG TO SVR THUNDERSTORMS AS A POSSIBILITY.
HOWEVER...AS WITH THIS MORNINGS SCENARIO...THE BEST LARGE SCALE
FORCING WILL REMAIN WELL NORTH OF AR THAT THE THREAT FOR WIDESPREAD
SVR WX LOOKS SOMEWHAT LIMITED AT THIS TIME. HOWEVER...UNCERTAINTIES
DO REMAIN REGARDING THE TIMING AND LOCATIONS OF THE FINER
DETAILS...SO WILL REFER TO THE LATEST DATA IN THE NEXT 24-36 HRS TO
SEE HOW THIS LATE WEEK STORM SYSTEM EVOLVES.

&&

.LONG TERM...SUNDAY THROUGH TUESDAY

HIGH PRESSURE WILL BUILD OVER THE REGION FROM THE PLAINS TO START
THE PERIOD. FROM THERE...A NORTHWEST WIND FLOW ALOFT WILL QUICKLY
TRANSITION TO MORE ZONAL. AS THE HIGH EXITS TO THE EAST ON
MONDAY/TUESDAY...SURFACE WIND WILL BECOME SOUTHERLY. THERE ARE
INDICATIONS OF A DEWPOINT SURGE AND AN INCREASE IN LOW CLOUDS
TUESDAY NIGHT. ADDED A SLIGHT CHANCE OF SHOWERS AS WELL.

TEMPERATURES WILL MODIFY THROUGH THE PERIOD...ESPECIALLY AS THE
HIGH RETREATS. READINGS WILL BE MOSTLY ABOVE NORMAL.
