AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LITTLE ROCK AR
1249 PM CDT TUE MAR 20 2012

.AVIATION...
HIGH PRESSURE CONTINUES TO THE EAST OF ARKANSAS AND LOW PRESSURE
TO THE WEST. SHOWERS AND THUNDERSTORMS CONTINUE TO STREAM NORTH
THROUGH CENTRAL...WESTERN...AND SOUTH ARKANSAS. THE RAIN WILL
BECOME MORE WIDESPREAD THIS EVENING AND OVERNIGHT. THERE WILL BE
SCATTERED THUNDERSTORMS DURING THE AFTERNOON AND EVENING HOURS.
VFR AND MVFR CONDIONS ARE MAINLY EXPECTED. SOME IFR CONDITIONS
WILL BE NOTED IN THE MORNING WITH LOWER CEILINGS AND VISIBILITIES
DUE TO RAIN AND FOG.

&&

.PREV DISCUSSION... /ISSUED 645 AM CDT TUE MAR 20 2012 /

AVIATION...
MAINLY VFR CEILINGS ALL TAFS WITH AREAS OF MVFR CEILINGS THIS
MORNING AND AFTERNOON. AREA OF SHOWERS AND STORMS HAVE HELD ALONG
THE OK TO AR STATE LINE THIS MORNING BUT TODAY MOVEMENT WILL BE VERY
SLOW TO THE EAST. STARTED WITH VCSH ALL TAFS THEN GRADUALLY VCTS
WITH CB CLOUDS LATE MORNING TO EARLY AFTERNOON...WEST TO CENTRAL.
THEN BETTER CHANCES OF SHOWERS AND THUNDERSTORMS LATER IN THE
AFTERNOON TO TONIGHT AS THE SYSTEM SLOWLY MOVES EAST. MVFR CEILINGS
MAINLY EXPECTED WITH CONVECTION. WINDS FROM THE S TO E 5 TO 15 KNOTS
THIS MORNING BECOMING 9 TO 18 KNOTS WITH SOME GUSTS AROUND 25 KNOTS
IN THE AFTERNOON. (59)

PREV DISCUSSION... /ISSUED 456 AM CDT TUE MAR 20 2012/

SHORT TERM...TODAY THROUGH FRIDAY NIGHT

HEAVY RAINFALL EVENT UNFOLDING ACROSS EASTERN OKLAHOMA...AND WILL
SLOWLY MOVE INTO ARKANSAS TODAY AND TONIGHT. MODELS OVERALL ARE IN
GOOD AGREEMENT...AND FOR THE MOST PART...HAVE MAINLY JUST FINE TUNED
THE ONGOING FORECAST.

WESTERN ARKANSAS HAS RECEIVED BETWEEN 0.50 TO 1 INCH AMOUNTS OVER
THE LAST SIX HOURS...WITH THE HEAVIEST RAINFALL REMAINING WEST OF
THE STATE LINE. THE COLD FRONT HAS SLOWED/STALLED OVER FAR EASTERN
OKLAHOMA/WESTERN ARKANSAS...WITH RAINFALL REMAINING IN THE SAME
AREAS THROUGH SUNRISE. RAINFALL WILL GRADUALLY MOVE EAST THIS
MORNING...REACHING THE LITTLE ROCK AREA AFTER NOON.

MAIN CHANGE WITH THIS FORECAST WAS TO INCREASE RAINFALL AMOUNTS
ACROSS THE SOUTHWEST INTO SOUTHERN COUNTIES...AND EXPAND THE FLASH
FLOOD WATCH. GULF MOISTURE WILL POOL ACROSS NORTHERN LOUISIANA AND
SOUTHERN ARKANSAS...AND HAVE INCREASED RAINFALL AMOUNTS ACROSS THE
SOUTHERN COUNTIES...WITH FOUR TO SIX INCHES COMMON. WITH MUCH OF THE
EASTERN HALF OF THE STATE REMAINING DRY FOR MUCH OF TODAY...HAVE
HELD OFF ON THE FLASH FLOOD WATCH FOR THESE AREAS UNTIL
TONIGHT...AND CONTINUE THIS AREA THROUGH WEDNESDAY NIGHT.

MODELS ARE ALL SHOWING THE COLD FRONT MOVING EAST OF THE AREA
WEDNESDAY NIGHT...WITH THE UPPER LOW MOVING ACROSS SOUTHERN MISSOURI
THURSDAY. HOWEVER...MODELS ARE USUALLY TOO FAST WITH THESE
SYSTEMS...AND HAVE HELD ON TO SMALL RAIN CHANCES THROUGH FRIDAY.

ONCE AGAIN...HEAVY RAINFALL IS AND WILL REMAIN THE MAJOR CONCERN
WITH THIS SYSTEM. THERE IS A SLIGHT RISK OF SEVERE STORMS ACROSS
MUCH OF THE AREA. HOWEVER...WITH CLOUD COVER/RAINFALL...STRONG
STORMS WILL BE HARD TO COME BY. WILL CONTINUE TO HIGHLIGHT THE FLOOD
CONCERNS...WITH DAMAGING WINDS THE MAIN CONCERN WITH ANY STRONG
STORM.

LONG TERM...SATURDAY THROUGH MONDAY

MODELS ARE IN GOOD AGREEMENT BY SATURDAY WITH THE SURFACE AND UPPER
LOWS HAVING MOVED TO THE OH TO TN VALLEYS. A NORTHWEST UPPER FLOW
WILL BE OVER AR WITH A LIGHT NW SURFACE FLOW INTO AR ON SATURDAY.
THROUGH SUNDAY TO MONDAY THE UPPER LOW CONTINUES TO PUSH EAST...
WHILE UPPER RIDGING BUILDS INTO THE PLAINS. AT THE SURFACE...HIGH
PRESSURE WILL MAINLY BE IN CONTROL OVER THE SOUTHERN PLAINS. DRY
WEATHER CONDITIONS ARE EXPECTED WITH ABOVE NORMAL TEMPS OF 5 TO 10
DEGREES ABOVE NORMAL.

500 AM CDT TUE MAR 20 2012

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

.DAY ONE...TODAY AND TONIGHT

A SLIGHT RISK OF SEVERE STORMS WILL BE POSSIBLE TODAY OVER PARTS
OF WESTERN TO CENTRAL ARKANSAS...AS THE STRONG STORM SYSTEM SLOWLY
DRIFTS EAST. THE MAIN THREATS WOULD BE DAMAGING WINDS AND LARGE
HAIL. AN ISOLATED SEVERE STORM MAY PRODUCE A TORNADO BUT THE
OVERALL THREAT IS LOW. THE GREATER THREAT TODAY WILL BE HEAVY
RAIN WITH POSSIBLE FLASH FLOODING. A FLASH FLOOD WATCH IS IN
EFFECT FOR MOST OF WESTERN ARKANSAS TODAY...AND PARTS OF CENTRAL
ARKANSAS LATER TODAY. ALSO A LAKE WIND ADVISORY IS IN EFFECT FOR
MUCH OF THE STATE.

FLASH FLOODING WILL BEGIN TO BE A CONCERN THROUGH THE DAY AND
TONIGHT...AS MORE AND MORE RAIN FALLS OVER WESTERN AND CENTRAL
ARKANSAS. RAIN AMOUNTS TODAY AND TONIGHT WILL BE FROM 1 TO 3
INCHES WITH ISOLATED HIGHER AMOUNTS. RESIDENTS ACROSS ARKANSAS
SHOULD MONITOR THIS WEATHER SITUATION CLOSELY DUE TO THE POTENTIAL
FOR FLASH FLOODING.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY

THE SLOW MOVING STRONG STORM SYSTEM WILL MOVE ACROSS ARKANSAS WEDNESDAY
THROUGH FRIDAY...AND CONTINUE TO BRING ROUNDS OF SHOWERS AND
THUNDERSTORMS...WITH HEAVY RAIN. DUE TO THE EXTENDED PERIOD OF
RAIN...THERE WILL BE A HIGH RISK OF FLASH FLOODING AND SOME RIVER
FLOODING. RAIN AMOUNTS OF 2 TO 4 INCHES ARE EXPECTED THROUGH
THURSDAY WITH ISOLATED HIGHER AMOUNTS POSSIBLE. IF THE WEATHER
SYSTEM MOVES EVEN A LITTLE BIT SLOWER THAN CURRENTLY EXPECTED...
SOME TOTALS IN THE WEST COULD EASILY EXCEED 8 INCHES. THESE HIGH
RAIN AMOUNTS WILL BRING FLASH FLOODING...WITH THE POTENTIAL FOR
HIGH WATER RESCUES AND LIFE THREATENING SITUATIONS. RIVER FLOODING
WOULD ALSO RESULT. A FLASH FLOOD WATCH WILL BE IN EFFECT FOR MOST
OF WESTERN AND CENTRAL ARKANSAS THROUGH WEDNESDAY. WATCHES MAY
HAVE TO BE EXTENDED BEYOND THAT TIME IF CONDITIONS WARRANT.

AREA RESIDENTS SHOULD MONITOR THIS DEVELOPING WEATHER SITUATION
CLOSELY DUE TO THE IMPACT OF POSSIBLE FLOODING RAINS.

THE STORM SYSTEM IS EXPECTED TO PUSH OUT OF ARKANSAS ON FRIDAY
WITH THE RAIN BECOMING MUCH LIGHTER AND ENDING. DRY WEATHER IS
FORECAST FOR THE WEEKEND.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION MAY BE NEEDED TODAY DUE TO THE SLIGHT RISK OF
SEVERE STORMS...AND IF FLASH FLOODING BECOMES LIFE THREATENING
ACROSS THE STATE.
