EVENT...CONVECTIVE WEDGE OVER THE SOUTHERN HALF OF THE OZARKS PRODUCING
LOCALLY HEAVY RAIN
.
SATELLITE ANALYSIS AND TRENDS...WELL DEFINED CONVECTIVE WEDGE HAS BEEN
ANCHORED OVER THE SOUTHERN HALF OF THE OZARKS REGION OF NW AR FOR THE
LAST 2 HOURS AND MANUAL SATELLITE ESTIMATES SUGGEST THAT 1-3" OF RAIN
HAS FELL OVER THE APPROXIMATE AREAS OF BENTON/CARROLL/MADISON COUNTIES.
.
LATEST WATER VAPOR IMAGERY SHOWS A NNE/SSW ORIENTED VORTICITY
LOBE EXTENDING FROM E IA THROUGH W MO THAT IS AIDING IN SYNOPTIC
DESTABILIZATION OVER THE REGION.  IN ADDITION, A BROADLY DIFFLUENT MID
AND UPPER LEVEL FLOW BETWEEN A SOMEWHAT AMPLIFYING EASTERN TROF AND
RIDGE OVER THE ROCKIES IS PROVIDING ADDITIONAL UPPER LEVEL SUPPORT.
SLOW MOVING/STATIONARY FRONTAL BOUNDARY HAS PLENTY OF MOISTURE TO WORK
WITH PER RECENT GPW/GOES DERIVED PRECIPITABLE WATERS OF NEAR 2.0".
.
VEERING LLJ CONTINUES TO FEED MOIST AND UNSTABLE AIR INTO THE BACK END
OF CONVECTIVE COMPLEX AND THIS HAS ALLOWED FOR CONTINUING CONVECTIVE
REGENERATION NEAR THE VIC OF BENTON COUNTY.  THE LAST SEVERAL IMAGES IT
DOES APPEAR AS THOUGH BACK END OF COMPLEX HAS MADE SOME SE PROGRESS BUT
STILL OVERALL CLOUD CANOPY CONTINUES TO COOL AND EXPAND ON LATEST 1215Z
IMAGERY WHICH SUGGESTS INTENSIFYING RAINFALL RATES DOWNSTREAM NEAR S
CARROLL/N MADISON ESE TO SEARCY COUNTY.  LOCAL AREA SOUNDINGS SHOWING
A HIGHLY PRECIP EFFICIENT PROFILE WITH DEEP MOISTURE ENVIRONMENT AND
LITTLE CLOUD LAYER SHEAR WHICH COULD LEAD TO LOCAL 2.0"/HR RAINFALL RATES.
.
BELIEVE OVERALL PATTERN OF BROADLY DIFFLUENT MID AND UPPER LEVEL FLOW,
SLOW MOVING FRONTAL BOUNDARY AND A UPSTRAEM DIFFLUENT THICKNESS PATTERN
SHOULD CONTINUE THE THREAT FOR LOCALLY HEAVY RAINFALL THROUGHOUT THE DAY.
WILL CONTINUE TO MONITOR.
