AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LITTLE ROCK AR
234 PM CDT SAT MAY 25 2013
.SHORT TERM...TONIGHT THROUGH TUESDAY NIGHT
CLOUDS WILL CONTINUE TO BE PREVALENT TONIGHT...AS MOISTURE
GRADIENT NEAR THE REMNANTS OF AN OLD FRONTAL BOUNDARY SURGE
NORTHWARD ACROSS THE STATE. AT THE SAME TIME...AN UPPER LEVEL
SYSTEM WILL MOVE THROUGH AND INTERACT WITH THESE REMNANTS. THE
RESULT WILL BE A CHANCE OF SHOWERS AND THUNDERSTORMS OVER THE
REGION TONIGHT THROUGH SUNDAY NIGHT.
MODELS HAVE COME BACK A LITTLE MORE BULLISH ON PRECIP CHANCES...
AND AS SUCH RAISED THEM SLIGHTLY IN MOST AREAS. STILL THOUGH...
AT THIS TIME...ONLY ISOLATED/SCATTERED SHOWERS/STORMS ARE
EXPECTED.
ANY LINGERING PRECIP ON SUNDAY EVENING WILL MOVE NORTHEAST OF THE
REGION BY LATE SUNDAY NIGHT...AS UPPER RIDGING BUILDS IN FROM THE
SOUTHWEST. THROUGH THE EARLY PART OF THE WEEK...A SLOW WARMING
TREND WILL BE NOTED...WITH AFTERNOON TEMPERATURES MAINLY IN THE
80S AND OVERNIGHT LOWS MAINLY IN THE 60S.
WITH LOW PRESSURE DEVELOPING IN THE PLAINS EARLY IN THE WEEK...THE
PRESSURE GRADIENT BETWEEN IT AND HIGH PRESSURE CENTERED OVER THE
SOUTHEAST CONUS WILL ALLOW FOR ELEVATED WINDS OVER THE REGION ON
MONDAY AND TUESDAY.
&&
.LONG TERM...WEDNESDAY THROUGH SATURDAY
SOUTHWESTERLY UPPER LEVEL FLOW WILL PREVAIL ACROSS THE MID SOUTH
DURING THIS PERIOD. EXPECT WIDELY SCATTERED...DIURNALLY DRIVEN
CONVECTION ACROSS AT LEAST WESTERN SECTIONS EACH DAY. NEAR NORMAL
TEMPERATURES ARE EXPECTED THROUGH THE PERIOD.

HIGH LEVEL CLOUDS WILL FILTER IN OVER AR...WHILE SOME SCATTERED
CLOUDS AT 4K FEET THIS AFTERNOON. WINDS WILL BE E TO S 5 TO 15 KNOTS
TODAY. ISOLATED LIGHT SHOWERS WILL BE SEEN THIS MORNING OVER
NORTHWEST AR...WHILE THIS AFTERNOON TO EARLY EVENING...ISOLATED
CONVECTION MAY BE SEEN OVER PARTS OF WESTERN AR. AT THIS TIME CHANCE
OF RAIN WILL BE LOW AND HAVE ONLY USED VCSH IN NORTHERN TAFS DUE TO
UNCERTAINTY. (59)

SHORT TERM...TODAY THROUGH TUESDAY NIGHT
UPPER LEVEL RIDGING CURRENTLY RESIDES OVER THE CENTRAL
CONUS...WITH THE RIDGE AXIS SITUATED FROM EASTERN TEXAS UP TO
EASTERN NEBRASKA...AND UPPER TROUGHS OVER NEW ENGLAND AND THE
PACIFIC NORTHWEST. TRAPPED BENEATH THE UPPER RIDGE IS A WEAK UPPER
DISTURBANCE OVER CENTRAL TEXAS...WHICH IS CAUSING SOME ONGOING
CONVECTION ACROSS TEXAS THIS MORNING.
THIS ENTIRE LONGWAVE PATTERN WILL SLOWLY SHIFT EAST OVER THE NEXT
DAY OR TWO BEFORE THE RIDGE FLATTENS OUT A BIT AND UPPER LEVEL
FLOW BECOMES SLIGHTLY MORE ZONAL ACROSS THE CONUS BY MONDAY
AFTERNOON. EXPECT MUCH OF THE SHORT TERM TO BE DRY...THOUGH SOME
RAIN CHANCES WILL EXIST MAINLY IN WESTERN THIS AFTERNOON AND THEN
IN WESTERN AND NORTHERN ARKANSAS ON SUNDAY. THE PROBLEM IN
CONVEYING THIS THROUGH THE FORECAST IS HOW HIGH OF RAIN CHANCES TO
PUT IN. FEEL PRETTY CONFIDENT THAT SHOWERS AND THUNDERSTORMS WILL
EXIST...BUT THEY ARE LIKELY TO BE ISOLATED TO WIDELY SCATTERED SO
MOST LOCALES...EVEN IN THE FAVORED AREAS...MAY NOT SEE ANY RAIN AT
ALL. AS SUCH...JUST LEFT SLIGHT CHANCE POPS IN FOR WESTERN
ARKANSAS THIS AFTERNOON AND THEN ACROSS MUCH OF THE FORECAST AREA
ON SUNDAY. RAIN CHANCES WILL BE HIGHEST ON SUNDAY...THANKS TO
INCREASING INFLUENCE FROM THE AFOREMENTIONED DISTURBANCE TRAPPED
BENEATH THE RIDGE AND ALSO ANOTHER WAVE TOPPING THE RIDGE AND
DROPPING SOUTHEAST ACROSS SOUTHERN MISSOURI.
DRY CONDITIONS ARE EXPECTED ON MONDAY AND TUESDAY.
WILL SEE A GRADUAL WARMING TREND MOVING THROUGH THE SHORT TERM.
HIGHS TODAY WILL BE IN THE MID 70S TO LOW 80S. BY TUESDAY
THOUGH...HIGHS SHOULD BE IN THE MID TO UPPER 80S STATEWIDE.
LONG TERM...WEDNESDAY THROUGH FRIDAY
MODELS ARE IN GOOD OVERALL AGREEMENT...WITH THE UPPER RIDGE OVER THE
EASTERN U.S. WHICH WILL GRADUALLY MOVE EAST AS A DEEPENING UPPER
TROUGH AND CUT OFF LOW OVER THE ROCKY MOUNTAINS WILL MOVE EAST. DRY
AND WARM WEATHER IS EXPECTED FOR WEDNESDAY AS INCREASING SOUTH WIND
FLOW RAISES MOISTURE LEVELS. THEN THE CHANCE OF RAIN ENTERS THE
FORECAST FOR THURSDAY AND FRIDAY...MAINLY IN THE WEST ON
THURSDAY...THEN OVER MUCH OF AR ON FRIDAY. THE UPPER AND SURFACE
SYSTEMS MOVE CLOSER TO AR...AND CHANCES OF CONVECTION GRADUALLY
INCREASE. ALTHOUGH THE MAIN CORE OF LIFT WITH THE UPPER TROUGH DOES
STAY WEST OF AR THURSDAY...THEN SHEERS OUT OVER AR ON FRIDAY.
THEREFORE AT THIS TIME ONLY A SLIGHT TO LOW CHANCE OF CONVECTION IS

1235 PM CDT FRI MAY 24 2013
.AVIATION...
HIGH PRESSURE CONTINUES OVER THE AREA. WINDS ARE FROM THE
NORTHEAST AND EAST WITH VERY FEW CLOUDS OVER THE AREA. WINDS WILL
BE GUSTY AT TIMES THIS AFTERNOON THEN DECREASE AFTER SUNSET.
CIRRUS WILL INCREASE OVER THE AREA LATE TONIGHT AND SATURDAY
MORNING. VFR CONDITIOINS WILL PREVAIL.
&&
.PREV DISCUSSION... /ISSUED 637 AM CDT FRI MAY 24 2013/
DISCUSSION...
UPDATED FOR THE 12Z AVIATION DISCUSSION BELOW.
AVIATION...
VFR CONDITIONS WILL PREVAIL THROUGH THE PERIOD. WINDS WILL BE
EASTERLY AROUND 10-12 KT AT ALL SITES...WITH SOME GUSTS INTO THE
MID TEENS DURING THE LATE MORNING AND AFTERNOON HOURS. WHILE THE
ATMOSPHERE IS CAPPED...THERE SHOULD BE ENOUGH SOLAR HEATING TO
DEVELOP SOME SPARSE AFTERNOON CU TODAY SO HAVE FEW040 MENTIONED AT
ALL SITES. SOME BKN040 CIGS MAY EXIST FROM JUST WEST OF
KLLQ...NORTHWEST THROUGH KHOT AND TOWARDS KFSM THIS AFTERNOON.
THIS WOULD BE IN A REGION OF HIGHEST MOISTURE CONVERGENCE JUST
NORTHEAST OF A STALLED FRONTAL BOUNDARY ACROSS NE TEXAS AND NRN
LOUISIANA. SOME CONVECTION WILL FIRE ALONG THAT BOUNDARY TODAY BUT
EXPECT ONLY CIRRUS BLOW OFF FROM IT ACROSS ARKANSAS.
PREV DISCUSSION... /ISSUED 309 AM CDT FRI MAY 24 2013/
SHORT TERM...TODAY THROUGH MONDAY
DRY CONDITIONS SEEN ACROSS THE STATE THIS MORNING AS WINDS FROM THE
NE USHER IN DRY AIR BEHIND A COLD FRONT. SKIES WERE PARTLY TO MOSTLY
CLOUDY AS HIGH CLOUDS FROM THE WEST MOVED OVER AR. EXPECT DRY
CONDITIONS TO PERSIST THROUGH THIS FRI AS DRIER AND COOLER AIR MOVES
INTO THE STATE. SOME LOCATIONS ACROSS THE FAR WEST AND SW COULD SEE
SOME ISOLATED CONVECTION...BUT KEEP BELOW MENTION POPS FOR NOW AS
POTENTIAL SEEMS TOO LOW AT THIS TIME. TEMPS WILL BE BELOW NORMAL FOR
HIGHS...WITH TEMPS MAINLY IN THE UPPER 60S TO UPPER 70S.
AFTER A COOL MORNING ON SAT...WITH MORNING LOWS IN THE UPPER 40S TO
UPPER 50S...MOISTURE LEVELS WILL BEGIN RETURNING ACROSS THE WEST AS
SFC HIGH PRESSURE SHIFTS EAST...AND UPPER LEVEL RIDGE AXIS BEGINS
SHIFTING EAST AS WELL. MOST LOCATIONS SHOULD REMAIN DRY HOWEVER...BUT
DO MENTION POPS ACROSS THE FAR WEST AND NW AS THERE WILL BE HIGHER
MOISTURE LEVELS IN THAT PORTION OF AR. BETTER POPS WILL BE SEEN ON
SAT NIGHT AND ESPECIALLY ON SUN AS A WEAK UPPER DISTURBANCE ROTATES
AROUND THE TOP OF THE RIDGE IN PLACE...MAINLY OVER NWRN AR. BEST
POPS WILL BE ACROSS THE NWRN AND NRN COUNTIES FOR SUN.
UPPER RIDGE WILL REMAIN IN PLACE THROUGH THE END OF THE
FORECAST...WITH MOST LOCATIONS REMAINING DRY FOR MON.
HOWEVER...COULD SEEN SOME DIURNALLY DRIVEN CONVECTION DURING THE
HEATING OF THE AFTERNOON HRS. WILL KEEP POPS BELOW MENTION AT THIS
TIME HOWEVER.
LONG TERM...TUESDAY THROUGH THURSDAY
NO NOTABLE CHANGES MADE TO THE LONG TERM FORECAST TONIGHT. MODELS
ARE GENERALLY IN GOOD AGREEMENT THROUGH THE PERIOD...SHOWING A RIDGE
UP UPPER LEVEL HIGH PRESSURE SITUATED OVER THE SOUTHEASTERN
CONUS..AND AN UPPER TROUGH OR CLOSED LOW DIGGING OUT A HOME ACROSS
THE DESERT SOUTHWEST. AS SUCH...THE FORECAST AREA SHOULD BE MOSTLY
DRY. HOWEVER WITH PERSISTENT AND SOMEWHAT DEEP SOUTHERLY FLOW AN
ISOLATED AFTERNOON SHOWER OR THUNDERSTORM WILL CERTAINLY BE POSSIBLE
EACH DAY. DID NOT PUT MENTION OF PRECIP IN THE FORECAST THOUGH AS
ANY CONVECTION SHOULD BE ISOLATED ENOUGH IN NATURE NOT TO WARRANT
BROAD-BRUSHED SLIGHT CHANCE POPS.
OTHERWISE...THE ONLY TWEAKS MADE TO THE FORECAST WOULD BE MINOR
TEMPERATURE ADJUSTMENTS TO ALIGN WITH LATEST GUIDANCE AND ALSO TO
ADJUST CLOUD COVER FORECASTS TO A MORE DIURNALLY FAVORED TREND.

.DISCUSSION...
UPDATED FOR THE 12Z AVIATION DISCUSSION BELOW.
&&
.AVIATION...
VFR CONDITIONS WILL PREVAIL THROUGH THE PERIOD. WINDS WILL BE
EASTERLY AROUND 10-12 KT AT ALL SITES...WITH SOME GUSTS INTO THE
MID TEENS DURING THE LATE MORNING AND AFTERNOON HOURS. WHILE THE
ATMOSPHERE IS CAPPED...THERE SHOULD BE ENOUGH SOLAR HEATING TO
DEVELOP SOME SPARSE AFTERNOON CU TODAY SO HAVE FEW040 MENTIONED AT
ALL SITES. SOME BKN040 CIGS MAY EXIST FROM JUST WEST OF
KLLQ...NORTHWEST THROUGH KHOT AND TOWARDS KFSM THIS AFTERNOON.
THIS WOULD BE IN A REGION OF HIGHEST MOISTURE CONVERGENCE JUST
NORTHEAST OF A STALLED FRONTAL BOUNDARY ACROSS NE TEXAS AND NRN
LOUISIANA. SOME CONVECTION WILL FIRE ALONG THAT BOUNDARY TODAY BUT
EXPECT ONLY CIRRUS BLOW OFF FROM IT ACROSS ARKANSAS.
&&
.PREV DISCUSSION... /ISSUED 309 AM CDT FRI MAY 24 2013/
SHORT TERM...TODAY THROUGH MONDAY
DRY CONDITIONS SEEN ACROSS THE STATE THIS MORNING AS WINDS FROM THE
NE USHER IN DRY AIR BEHIND A COLD FRONT. SKIES WERE PARTLY TO MOSTLY
CLOUDY AS HIGH CLOUDS FROM THE WEST MOVED OVER AR. EXPECT DRY
CONDITIONS TO PERSIST THROUGH THIS FRI AS DRIER AND COOLER AIR MOVES
INTO THE STATE. SOME LOCATIONS ACROSS THE FAR WEST AND SW COULD SEE
SOME ISOLATED CONVECTION...BUT KEEP BELOW MENTION POPS FOR NOW AS
POTENTIAL SEEMS TOO LOW AT THIS TIME. TEMPS WILL BE BELOW NORMAL FOR
HIGHS...WITH TEMPS MAINLY IN THE UPPER 60S TO UPPER 70S.
AFTER A COOL MORNING ON SAT...WITH MORNING LOWS IN THE UPPER 40S TO
UPPER 50S...MOISTURE LEVELS WILL BEGIN RETURNING ACROSS THE WEST AS
SFC HIGH PRESSURE SHIFTS EAST...AND UPPER LEVEL RIDGE AXIS BEGINS
SHIFTING EAST AS WELL. MOST LOCATIONS SHOULD REMAIN DRY HOWEVER...BUT
DO MENTION POPS ACROSS THE FAR WEST AND NW AS THERE WILL BE HIGHER
MOISTURE LEVELS IN THAT PORTION OF AR. BETTER POPS WILL BE SEEN ON
SAT NIGHT AND ESPECIALLY ON SUN AS A WEAK UPPER DISTURBANCE ROTATES
AROUND THE TOP OF THE RIDGE IN PLACE...MAINLY OVER NWRN AR. BEST
POPS WILL BE ACROSS THE NWRN AND NRN COUNTIES FOR SUN.
UPPER RIDGE WILL REMAIN IN PLACE THROUGH THE END OF THE
FORECAST...WITH MOST LOCATIONS REMAINING DRY FOR MON.
HOWEVER...COULD SEEN SOME DIURNALLY DRIVEN CONVECTION DURING THE
HEATING OF THE AFTERNOON HRS. WILL KEEP POPS BELOW MENTION AT THIS
TIME HOWEVER.
LONG TERM...TUESDAY THROUGH THURSDAY
NO NOTABLE CHANGES MADE TO THE LONG TERM FORECAST TONIGHT. MODELS
ARE GENERALLY IN GOOD AGREEMENT THROUGH THE PERIOD...SHOWING A RIDGE
UP UPPER LEVEL HIGH PRESSURE SITUATED OVER THE SOUTHEASTERN
CONUS..AND AN UPPER TROUGH OR CLOSED LOW DIGGING OUT A HOME ACROSS
THE DESERT SOUTHWEST. AS SUCH...THE FORECAST AREA SHOULD BE MOSTLY
DRY. HOWEVER WITH PERSISTENT AND SOMEWHAT DEEP SOUTHERLY FLOW AN
ISOLATED AFTERNOON SHOWER OR THUNDERSTORM WILL CERTAINLY BE POSSIBLE
EACH DAY. DID NOT PUT MENTION OF PRECIP IN THE FORECAST THOUGH AS
ANY CONVECTION SHOULD BE ISOLATED ENOUGH IN NATURE NOT TO WARRANT
BROAD-BRUSHED SLIGHT CHANCE POPS.
OTHERWISE...THE ONLY TWEAKS MADE TO THE FORECAST WOULD BE MINOR
TEMPERATURE ADJUSTMENTS TO ALIGN WITH LATEST GUIDANCE AND ALSO TO
ADJUST CLOUD COVER FORECASTS TO A MORE DIURNALLY FAVORED TREND.
MORNING CLOUDINESS SHOULD BE FAIRLY PREVALENT EACH DAY...ESPECIALLY
IN THE WEST...BUT THIS SHOULD GIVE WAY TO AFTERNOON CUMULUS AND THEN
CLEARING SKIES IN THE EVENING WITH LOSS OF DAYTIME HEATING.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LITTLE ROCK AR
1025 PM CDT THU MAY 23 2013
.UPDATE...
MADE A FEW ADJUSTMENTS TO THE FORECAST OVERNIGHT BASED
ON LATEST TRENDS IN TEMPS...CLOUDS...AND WINDS. NO MAJOR CHANGES
BUT I LOWERED WIND SPEEDS JUST A BIT OVERNIGHT AND RAISED
DEWPOINTS AND TEMPERATURES JUST A DEGREE OR TWO ACROSS THE
NORTHERN HALF OF THE STATE. LOOKS AS IF THE COOLER AND DRIER AIR
IS A BIT SLOWER FILTERING IN THAN EXPECTED AND A BIT MORE CLOUD
COVER HAS KEPT TEMPS JUST A BIT HIGHER TONIGHT THAN EXPECTED. 53
.PREV DISCUSSION... /ISSUED 624 PM CDT THU MAY 23 2013/
AVIATION...
VFR THROUGH0UT THIS FORECAST PERIOD. SCT MID CLOUDS AT TIMES WITH
BKN HIGH CLOUDS ABOVE. LOOKS LIKE WE WILL HAVE SOME BREEZY WINDS
BEGINNING SOON AFTER SUNRISE IN CENTRAL AND S AR...SO BUMPED UP
THE WIND FORECAST THEN.
PREV DISCUSSION... /ISSUED 239 PM CDT THU MAY 23 2013/
SHORT TERM...TONIGHT THROUGH SUNDAY NIGHT
AT THE SURFACE...A STATIONARY FRONTAL BOUNDARY IS SET UP JUST TO
THE SOUTH OF THE REGION. UPPER WAVE HAS TOUCHED OFF SHOWERS/STORMS
IN OKLAHOMA...WHICH HAVE WANED IN THE LAST FEW HOURS. THE CIRRUS
SHIELD FROM THE STORMS HAS KEPT TEMPERATURES MOSTLY IN THE 70S IN
THE NORTHWEST HALF OF THE STATE...WHILE READINGS ELSEWHERE HAVE
BEEN IN THE LOWER TO MID 80S.
THERE WILL BE SMALL CHANCES FOR SHOWERS/STORMS THIS EVENING IN THE
FAR SOUTHWEST...CLOSE TO THE FRONTAL BOUNDARY AND ANY INTERACTION
WITH THE REMNANTS FROM THE MORNING SYSTEM. OTHERWISE...COOLER AND
DRIER AIR WILL CONTINUE TO PUSH INTO THE REGION BEHIND THE FRONT...
WITH UPPER RIDGING BUILDING SOMEWHAT OVER THE REGION.
WITH CLOUD COVER AND NORTHEAST/EASTERLY FLOW...HIGHS ON FRIDAY
WILL MOSTLY BE IN THE 70S. LOWS TONIGHT AND FRIDAY NIGHT WILL
MAINLY BE IN THE 50S.
SLOW WARMING WILL COMMENCE DURING THE WEEKEND. EVEN SO...FAIRLY
PLEASANT TEMPERATURES WILL CONTINUE. BY LATE SATURDAY INTO SUNDAY...
THE AFOREMENTIONED UPPER RIDGE WILL SHIFT A BIT...ALLOWING FOR
SEVERAL WAVES TO MOVE THROUGH AROUND THE PERIPHERY OF IT. AT THE
SAME TIME...THE FRONTAL BOUNDARY THAT MOVED THROUGH TODAY WILL
MOVE BACK TO THE NORTH AS A WARM FRONT. THIS WILL ALLOW FOR
SCATTERED SHOWERS/STORMS TO BE POSSIBLE...MAINLY IN THE AFTERNOON
AND EARLY EVENING HOURS AS THE SYSTEMS INTERACT.
LONG TERM...MONDAY THROUGH THURSDAY
AN UPPER RIDGE WILL BE OVER THE AREA TO BEGIN THE PERIOD WITH AN
UPPER TROUGH OVER THE WESTERN U.S. AND AN UPPER LOW OVER THE
NORTHEAST U.S. THE UPPER RIDGE STARTS TO MOVE EAST TUESDAY AND THE
UPPER TROUGH MOVES TO THE ROCKIES WEDNESDAY. SOUTHWEST FLOW ALOFT
WILL BE OVER ARKANSAS WEDNESDAY AND THURSDAY.
MODELS ARE IN SIMILAR AGREEMENT FOR THE EXTENDED PERIOD. A
STATIONARY FRONT IS EXPECTED TO BE OVER SOUTHERN ARKANSAS MONDAY
MORNING. MOISTURE OVERRUNNING THIS FRONT MAY CAUSE ISOLATED SHOWERS
AND THUNDERSTORMS ACROSS THE NORTH. KEPT THE SLIGHT CHANCE IN THE
NORTH FOR MONDAY THROUGH TUESDAY MORNING. SURFACE HIGH PRESSURE
BUILDS INTO THE AREA FROM THE EAST WEDNESDAY AND THURSDAY AND THIS
SHOULD DECREASE PRECIPITATION CHANCES. TEMPERATURES WILL BE SLIGHTLY
WARMER BEHIND THE FRONT AND WILL REMAIN ABOVE NORMAL THROUGH THE
PERIOD.
