AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE LITTLE ROCK AR
843 PM CDT TUE MAY 24 2011

.UPDATE...

HAVE UPDATED FORECAST TO INCLUDE TOR WATCH 364 THROUGH 08Z. HAVE
ALSO BUMPED POPS ACROSS WRN AR...AS WELL AS ADDED SVR WORDING TO
THOSE AREAS OF THE CWA. OTHERWISE...NO OTHER SIGNIFICANT CHANGES
EXPECTED.

&&

.PREV DISCUSSION... /ISSUED 635 PM CDT TUE MAY 24 2011/

AVIATION...

SCATTERED CONVECTION WILL MOVE INTO WESTERN ARKANSAS THIS EVENING
AND EVENTUALLY SPREAD EAST THROUGH THE PERIOD. THUNDERSTORM
ACTIVITY WILL GRADUALLY EVOLVE INTO A SQUALL LINE OVERNIGHT AND
IMPACT MAINLY KHRO AND KBPK WHERE MVFR/IFR CONDITIONS WILL OCCUR.
PRECIPITATION CHANCES WILL BE LESS AT THE REMAINDER OF THE TAF
SITES BUT OCCASIONAL MVFR CONDITIONS WILL BE POSSIBLE. THE
ASSOCIATED SURFACE LOW WILL BE CENTERED OVER CENTRAL KANSAS EARLY
WEDNESDAY MORNING. THIS WILL RESULT IN BREEZY SOUTHERLY FLOW
ACROSS THE TERMINALS. LOW CLOUDS ARE LIKELY TO DEVELOP AND SPREAD
INTO SOUTHERN AND CENTRAL ARKANSAS LATER TONIGHT. PRECIPITATION
CHANCES WILL RETURN LATE IN THE PERIOD AS ANOTHER DISTURBANCE
SWINGS AROUND THE PARENT LOW PRESSURE SYSTEM.

PREV DISCUSSION... /ISSUED 308 PM CDT TUE MAY 24 2011/

SHORT TERM...TONIGHT THROUGH FRIDAY NIGHT

THE MAIN CONCERN IN THE SHORT TERM REVOLVES AROUND THE LOCATION
AND PROBABILITY OF SEVERE WEATHER. A SIGNIFICANT SEVERE WEATHER
EVENT IS UNFOLDING ACROSS OKLAHOMA THIS AFTERNOON AND
EVENING. EVENTUALLY...THUNDERSTORMS WILL SHIFT EAST ACROSS
NORTHERN ARKANSAS TONIGHT. THE BEST CHANCES WILL ROUGHLY BE
NORTHWEST OF A LINE FROM CLARKSVILLE TO MOUNTAIN HOME. I BELIEVE
THE BIGGEST THREAT WILL BE WIND AND TO A LESSER EXTENT HAIL. WHILE
LOW LEVEL SHEAR WILL BE FAIRLY HIGH TONIGHT...THE LATE ARRIVAL
TIME OF STORMS SHOULD ALLOW A FAIRLY DEEP AND STABLE SFC INVERSION
TO SET UP...THUS INHIBITING TORNADIC POTENTIAL TONIGHT. WILL KEEP
CHANCE POPS IN CENTRAL AR IN THE VICINITY OF THE I-40
CORRIDOR...WITH SLIGHT CHANCE POPS IN THE SOUTH AS HIRES MODELS
SHOW SOME INDICATION OF A MCS MOVING ACROSS THE SOUTHERN CWA
TONIGHT.

FOR WEDNESDAY...THE BEST CHANCES FOR SEVERE WEATHER WILL BE IN THE
EAST HALF OF THE CWA. SOME LINGERING SHOWERS WILL LIKELY BE
PRESENT DURING THE EARLY PART OF THE DAY TOMORROW...BUT MORE
SIGNIFICANT STORM DEVELOPMENT WILL OCCUR IN THE AFTERNOON. STORM
PARAMETERS WILL SUPPORT DAMAGING WINDS...LARGE HAIL AND EVEN
TORNADOES. THE UPPER LOW AND ASSOCIATED COLD FRONT THAT ARE
RESPONSIBLE FOR THIS ROUND OF SEVERE WEATHER WILL SHIFT EAST OF
THE AREA LATE WED NIGHT. PRECIP CHANCES WILL DIMINISH QUICKLY FROM
THE WEST WEDNESDAY NIGHT.

COOLER AIR WILL FILTER INTO THE STATE BEHIND THE FRONT. HIGHS ON
THURSDAY WILL RANGE FROM AROUND 70 IN THE NORTH TO AROUND 80 IN
THE SOUTH...A GOOD 5-10 DEGREES COOLER THAN THOSE ON WEDNESDAY.
FRIDAY WILL BE A TAD WARMER AS SOUTHERLY FLOW RESUMES ACROSS THE
STATE.

LONG TERM...SATURDAY THROUGH TUESDAY

MODELS ARE IN REASONABLE AGREEMENT THRU THE PD AS WE TRANSITION TO A
WARM AND DRY PATTERN. UPR LVL HIGH PRES WL STRENGTHEN OVR THE SERN
STATES...INCLUDING THE MID SOUTH. A WARM FNT WL BE RETREATING TO THE
N OF AR EARLY ON SAT...WITH SOME LINGERING SHRA/TSRA POSSIBLE.
OTHERWISE...WARM SLY WINDS WL LEAD TO ABV NORMAL TEMPS ACRS THE FA
AS THE PD PROGRESSES. LTL SUPPORT FOR ORGANIZED PRECIP...SO CONTD
WITH A DRY FCST.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR A LARGE PART OF ARKANSAS.

.DAY ONE...TONIGHT

ANOTHER ROUND OF STRONG AND SEVERE THUNDERSTORMS IS EXPECTED TO
IMPACT MUCH OF ARKANSAS TONIGHT. THERE IS A RISK OF SEVERE WEATHER
OVER MUCH OF NORTHERN AND CENTRAL SECTIONS OF THE STATE. A TORNADO
WATCH IS NOW IN EFFECT UNTIL 3 AM WEDNESDAY MORNING ROUGHLY ALONG A
LINE FROM MELBOURNE TO CLINTON TO PERRYVILLE TO HOT SPRINGS TO
ARKADELPHIA AND POINTS WEST.

LOW PRESSURE LOCATED OVER WESTERN KANSAS WILL CONTINUE TO TRACK TO
THE EAST THROUGH THE OVERNIGHT HOURS. NUMEROUS THUNDERSTORMS HAVE
DEVELOPED ALONG A COLD FRONT THIS EVENING THAT EXTENDS FROM THE LOW
OVER EASTERN OKLAHOMA AND WILL BE SWEEPING EASTWARD DURING THE
OVERNIGHT HOURS.

THE STORMS THAT HAVE FORMED TO THE WEST OF ARKANSAS HAVE HAD A
HISTORY OF PRODUCING SEVERE WEATHER. FORECAST WIND PROFILES INDICATE
THAT THESE STORMS WILL BE CAPABLE OF ROTATING AND POSSIBLY PRODUCE
TORNADOES.

AS THE EVENING PROGRESSES...THE STORMS WILL INCREASE IN COVERAGE AND
CONVERGE INTO A SQUALL LINE. DAMAGING WINDS AND LARGE HAIL WILL BE
THE PRIMARY THREAT ...ALTHOUGH ISOLATED TORNADOES CANNOT BE RULED
OUT. THE THUNDERSTORMS WILL SLOWLY WEAKEN WITH TIME THE FURTHER EAST
THEY MOVE.

IN ADDITION...ANY THUNDERSTORM THAT DEVELOPS COULD PRODUCE LOCALLY
HEAVY RAINFALL. A FLASH FLOOD WATCH REMAINS IN EFFECT THROUGH
WEDNESDAY MORNING FOR THE NORTHERN HALF OF ARKANSAS.

RIVER FLOODING CONTINUES ACROSS EASTERN ARKANSAS. WHILE MOST RIVERS
HAVE CRESTED...SOME ARE RISING AGAIN...AND THE WATER WILL BE VERY
SLOW TO RECEDE. A FEW ROADS IN EASTERN SECTIONS OF THE STATE REMAIN
CLOSED.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY

SEVERE WEATHER WILL AGAIN BE POSSIBLE ON WEDNESDAY ACROSS MUCH OF
ARKANSAS. THIS IS DUE TO A STALLED FRONT TO THE NORTH AND WEST OF
ARKANSAS...ALONG WITH A SERIES OF UPPER LEVEL STORM SYSTEMS THAT
WILL INTERACT WITH THE FRONT. ALL OF ARKANSAS WILL HAVE A RISK OF
SEVERE WEATHER WEDNESDAY AFTERNOON AND EVENING...WITH THE GREATEST
CHANCES EAST OF A MOUNTAIN HOME...HOT SPRINGS...TO GURDON TO CAMDEN
LINE. ONCE AGAIN...THE PRIMARY THREATS WILL BE DAMAGING WINDS...
LARGE HAIL AND ISOLATED TORNADOES.

RAINFALL AMOUNTS OF ONE TO THREE INCHES ARE POSSIBLE IN THE NORTHERN
AND CENTRAL COUNTIES NEAREST THE FRONT. THIS COULD LEAD TO RISES ON
AREA RIVERS...BUT NOT TO THE LEVELS REACHED EARLIER THIS MONTH. A
FLASH FLOOD WATCH REMAINS IN EFFECT FOR NORTHERN ARKANSAS THROUGH
WEDNESDAY MORNING.

IT APPEARS THE FRONT WILL FINALLY GAIN SOME MOMENTUM AND MOVE TO THE
SOUTHEAST OF ARKANSAS BY THURSDAY. IT APPEARS FRIDAY AND MOST OF THE
UPCOMING HOLIDAY WEEKEND WILL BE DRY AND WARM AS HIGH PRESSURE
SETTLES OVER THE AREA.

RIVER FLOODING WILL REMAIN AN ISSUE ACROSS EASTERN ARKANSAS FOR THE
NEXT SEVERAL DAYS.

STAY TUNED TO LATER FORECASTS. INDIVIDUALS ARE ENCOURAGED TO MONITOR
NATIONAL WEATHER SERVICE FORECASTS FOR THE LATEST ON RIVER LEVELS.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION IS EXPECTED LATE THIS AFTERNOON AND TONIGHT.
