AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LITTLE ROCK AR
241 PM CDT WED JUL 13 2011

.SHORT TERM...TONIGHT THROUGH SATURDAY NIGHT

SHOWERS AND THUNDERSTORMS ARE DEVELOPING THIS AFTERNOON IN
WESTERN AND SOUTHWESTERN ARKANSAS. FOR THE NEXT COUPLE OF HOURS
THE FOCUS WILL BE PRIMARILY ALONG AN OUTFLOW BOUNDARY IN SWRN
ARKANSAS THAT WAS EJECTED SOUTHWARD FROM CONVECTION IN THE NRN
PART OF THE STATE THIS MORNING. HOWEVER AS THE MUCH TALKED ABOUT
UPPER WAVE...CURRENTLY OVER NE OK...MOVES OVER ARKANSAS OVER THE
NEXT 24 HOURS...MORE SCATTERED CONVECTION SHOULD DEVELOP ACROSS
THE STATE. HAVE BROAD BRUSHED 40 PERCENT POPS THIS EVENING TO
ACCOUNT FOR SCT THUNDERSTORMS. WITH REGARD TO THREATS...STRONGER
STORMS WILL BE CAPABLE OF STRONG WINDS AND SOME LARGER HAIL. FLASH
FLOODING COULD BE A CONCERN AS WELL AS SOME AREAS HAVE ALREADY
SHOWN EVIDENCE OF TRAINING STORMS...BUT THIS WOULD BE A LESS
WIDESPREAD THREAT.

IN TERMS OF TEMPERATURES AND HEAT ADVISORIES...THE UPPER RIDGE
WILL CONTINUE TO REMAIN IN CONTROL OF THE WEATHER ACROSS THE
STATE OVER THE NEXT FEW DAYS SO TEMPERATURES WILL CONTINUE TO BE
WARM AND SUMMER LIKE. HAVE CONTINUED THE HEAT ADVISORY THROUGH THIS
EVENING FOR CENTRAL ARKANSAS...AND THROUGH THURSDAY FOR THE SE
PART OF THE FORECAST AREA. HOWEVER...CONDITIONS IN THE NORTH
WERE COOLED SIGNIFICANTLY THIS MORNING FROM CONVECTION OVER THE
FAR NRN PARTS OF THE STATE. SIMILAR CONDITIONS COULD OCCUR OVER
PARTS OF SRN AND SERN ARKANSAS TONIGHT...WHICH WOULD MEAN THE HEAT
ADVISORY COVERING THOSE AREAS MAY GET MASSAGED A BIT BY LATER SHIFTS.

STILL...TEMPS IN THE MID TO UPPER 90S IN THE SOUTH WITH HEAT INDEX
VALUES AROUND OR SLIGHTLY OVER 100 SEEM PROBABLE TOMORROW.

FOR FRIDAY...HAVE ONLY SLIGHT CHANCE POPS IN THE FORECAST. UPPER
WAVE WILL NOT BE AS POTENT BUT ENOUGH ENERGY WILL REMAIN...AND
LIKELY ENOUGH REMNANT SFC BOUNDARIES IN PLACE...TO SPARK OFF AT
LEAST SOME ISOLATED STORMS FRI AFTERNOON. WILL NEED TO LOOK AT
HEAT ADVISORIES FOR FRIDAY AS HEAT INDEX VALUES WILL ONCE AGAIN BE
BACK ABOVE 105 DEGREES FOR A LARGE PART OF THE FORECAST AREA.

&&

.LONG TERM...SUNDAY THROUGH WEDNESDAY

NOT MUCH CHANGE TO THE LONG TERM...WITH THE STRONG UPPER LEVEL
RIDGE SCOOTING NORTH INTO MO AND ALLOWING GULF MOISTURE TO RIDE
THROUGH LA AND INTO SOUTHERN AR. BEST CHANCE FOR PRECIP WILL EXIST
OVER THE SOUTHERN HALF OF THE STATE THROUGH THE PERIOD...AND IN
THE AFTERNOON/EVENING HOURS. TEMPS AND DEW PTS WILL REMAIN 3 TO 5
DEGREES ABOVE SEASONAL AVERAGES...BUT WILL BE A FEW DEGREES COOLER
THAN THIS WEEK.

SEVERE WEATHER IS NOT EXPECTED...THOUGH ANY STORM THAT DOES FORM
COULD BECOME STRONG TO SEVERE WITH DAMAGING WINDS THE GREATEST
THREAT.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY

SOME MINOR RELIEF IN THE VERY HOT TEMPERATURES IS EXPECTED FOR THE
LATTER HALF OF THE WORK WEEK AS THE PERSISTENT UPPER LEVEL HIGH
WEAKENS. THIS WILL ALLOW SEVERAL UPPER LEVEL IMPULSES TO PASS ACROSS
ARKANSAS...RESULTING IN ISOLATED TO SCATTERED SHOWERS AND
THUNDERSTORMS EACH AFTERNOON AND EVENING.

WIDESPREAD AND ORGANIZED SEVERE WEATHER IS NOT EXPECTED...THOUGH ANY
STORM THAT DOES FORM COULD BECOME STRONG TO SEVERE WITH DAMAGING
