AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LITTLE ROCK AR 350 AM CDT THU MAY 4 2006 .SHORT TERM...TODAY THROUGH SUNDAY RADAR AND SATELLITE IMAGERY CURRENTLY SHOWING SEVERAL MESOSCALE SYSTEMS AFFECTING THE FORECAST AREA. FIRST SYSTEM OVER NORTH CENTRAL/ NORTHEAST ARKANSAS DEVELOPED ALONG THE REMNANTS OF AN OLD FRONTAL BOUNDARY. EASILY SEEN OUTFLOW GENERATED BY THIS SYSTEM WILL NO DOUBT ACT AS SOME FOCUS FOR ADDITIONAL DEVELOPMENT ONCE THE HEATING OF THE DAY KICKS IN. THE OTHER SYSTEM DEVELOPED OVER EASTERN OKLAHOMA INVOF SURFACE LOW AND ATTENDANT COLD FRONT. THE FRONT IS CURRENTLY MOVING INTO FAR NORTHWEST ARKANSAS. CURRENT SYSTEM IN OKLAHOMA/NORTHWEST ARKANSAS WILL WEAKEN IN THE NEXT SEVERAL HOURS. HOWEVER...ADDITIONAL SHOWERS AND THUNDERSTORMS WILL OCCUR AS THE FRONT MAKES ITS WAY INTO THE STATE AND INTERACTS WITH DAYTIME HEATING AND OUTFLOW FROM PREVIOUS CONVECTION. PRIMARY CONCERN WITH THIS PACKAGE WILL BE THREAT OF LOCALLY HEAVY RAINFALL TODAY AND TONIGHT. AS THE SURFACE FRONT SAGS SOUTHWARD INTO ARKANSAS...A SHORTWAVE TROUGH WILL MOVE THROUGH AND INTERACT WITH THE SYSTEM. THIS INTERACTION...ALONG WITH PLENTY OF ISENTROPIC UPLIFT AND PRECIPITABLE WATER VALUES IN THE 1-2 INCH RANGE WILL ALLOW FOR ONE TO TWO INCH RAINFALL AMOUNTS IN PORTIONS OF NORTHERN AND WESTERN ARKANSAS. STORM MOTION WILL BE AROUND 10-15 KNOTS... MEANING THAT THE STORMS WILL BE SLOW MOVERS. AS HAS BEEN THE TREND OVER THE LAST FEW HOURS...STORMS WILL LIKELY FORM AND MOVE OVER THE SAME AREAS WHICH WILL ALSO INCREASE THE FLASH FLOOD THREAT. AS LOW AS FLASH FLOOD GUIDANCE IS...AND AS SATURATED AS THE GROUND HAS BEEN...AM GOING TO GO WITH A FLASH FLOOD WATCH FOR AREAS NORTH OF A LINE FROM WALDRON...TO CONWAY...TO AUGUSTA. SEVERE STORM THREAT WILL CONTINUE TODAY THROUGH FRIDAY...WITH HAIL AND WIND BEING THE PRIMARY CONCERN. AS THE UPPER FLOW BUCKLES EARLY FRIDAY MORNING...THE FRONT WILL GAIN A LITTLE MORE MOMENTUM. THE FRONT WILL PUSH OUT OF THE STATE BY LATE FRIDAY NIGHT. HOWEVER...MOISTURE WILL REMAIN ABUNDANT OVER THE REGION...WITH SEVERAL UPPER LEVEL SYSTEMS MOVING THROUGH. THUS... KEPT POPS IN THE FORECAST THROUGH SUNDAY TO ACCOUNT FOR THIS. FRONT ITSELF WILL STALL OUT JUST SOUTH OF ARKANSAS ON SUNDAY...MOVING BACK TO THE NORTH SOME TIME NEXT WEEK. THANKS TO WFO TULSA FOR COORDINATION THIS MORNING. && .LONG TERM...SUNDAY NIGHT THROUGH WEDNESDAY MOISTURE REMAINS HIGH ACROSS THE AREA THROUGH THE PERIOD. SURFACE HIGH PRESSURE TO THE NORTH WILL COVER THE AREA AT FIRST WITH COOLER AIR IN PLACE BUT THIS WEAKENS ON MONDAY ALLOWING FOR WINDS TO TURN AROUND TO THE SOUTH AND BRING MORE MOISTURE IN. MEANWHILE THE UPPER LOW OVER THE SOUTHWEST WILL COME OUT EARLY NEXT WEEK BUT WEAKEN AS IT GETS ABSORBED INTO THE MAIN UPPER FLOW. A COLD FRONT THEN APPROACHES THE AREA FROM THE NORTHWEST TUESDAY AS AN UPPER LOW SETTLES INTO SOUTHERN CANADA. INDICATIONS ARE THIS FRONT WILL REACH NORTHERN AREAS OF THE CWA THEN STALL BEFORE FINALLY MOVING THROUGH WEDNESDAY NIGHT. OF COURSE THIS TIMING IS SUBJECT TO CHANGE. AT ANY RATE WILL NEED TO HAVE MENTION OF SOME CHANCE OF SHOWERS AND THUNDERSTORMS IN THE FORECAST THROUGH MOST OF THE PERIOD. KEPT FORECAST DRY FOR SUNDAY NIGHT THEN HAVE POPS IN THE 20 TO 40 PERCENT RANGE FOR THE REST OF THE PERIOD. KEPT TEMP FORECASTS THE SAME EXCEPT FOR MINS NEXT WEDNESDAY NIGHT. RAISED THEM SOME AS THE COLD FRONT IS INDICATED TO BE HANGING TO THE NORTH OF THE AREA. && .PRELIMINARY POINT TEMPS/POPS...
