AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LITTLE ROCK AR
656 PM CDT MON JUN 25 2012

.AVIATION...
WIDESPREAD VFR CONDITIONS WILL CONTINUE THROUGH THE PERIOD WITH
ONLY A FEW MID LEVEL CLOUDS EXPECTED. A WEAK COLD FRONT WILL MOVE
THROUGH THE STATE BUT NO PRECIPITATION IS EXPECTED WITH THIS
FEATURE AND ITS PASSAGE WILL ONLY BE MARKED BY A SUBTLE WIND
SHIFT.

&&

.PREV DISCUSSION... /ISSUED 245 PM CDT MON JUN 25 2012/

SHORT TERM...TONIGHT THROUGH THURSDAY NIGHT

19Z SURFACE OBSERVATIONS INDICATE A NUMBER OF LOCAL SITES HAVE
SURPASSED 100 DEGREES...WITH SOME SITES REACHING RECORD LEVELS FOR THE
DAY...AND A FEW REACHING RECORD HIGHS FOR THE MONTH.

19Z OBJECTIVE SURFACE ANALYSIS INDICATES A WEAK FRONTAL BOUNDARY
ACROSS CENTRAL MISSOURI. SOME MOISTURE POOLING WAS NOTED AHEAD OF
THIS FEATURE...CONTRIBUTING TO SUBSTANTIAL CAPE VALUES... >4000
J/KG. FORCING ALONG THE BOUNDARY APPEAR TO BE VERY WEAK. 18Z LZK
SOUNDING INDICATES SUBSTANTIAL CONVECTIVE INHIBITION REMAINING.
HOWEVER...IF ANY CONVECTION COULD FORM ALONG THE BOUNDARY...THERE
WOULD BE A MICROBURST THREAT.

COOLER TEMPERATURES SHOULD BE NOTED ACROSS AT LEAST THE NORTHERN
HALF OF THE FORECAST AREA FOR TUESDAY AND WEDNESDAY.  ABOVE NORMAL
TEMPERATURES WILL DEVELOP AGAIN LATE IN THE PERIOD...ALTHOUGH
THERE IS SOME INDICATIONS THAT THE STRONG UPPER LEVEL RIDGE ACROSS
THE CENTRAL PLAINS...THAT HAS CONTRIBUTED TO THE HOT
CONDITIONS...WILL SLIDE TO THE WEST AND WEAKEN.

LONG TERM...FRIDAY THROUGH MONDAY

OVERALL LITTLE CHANGE IN THE EXTENDED FORECAST. AN OVERALL ABSENCE
OF ANY SURFACE OR UPPER WEATHER SYSTEMS WILL CONTINUE THE DRY AND
HOT WEATHER OVER THE SOUTHERN PLAINS. THE UPPER LEVEL HIGH PRESSURE
RIDGE REMAINS THE MAIN FEATURE OVER THE AREA KEEPING A CAP ON ANY
CONVECTION POTENTIAL...AS WELL HAS HELPING KEEP TEMPERATURES HOT. AT
THE SURFACE LITTLE CHANGE IS SEEN WITH OVERALL SURFACE HIGH
PRESSURE. ON THURSDAY TO FRIDAY A SOUTH WIND FLOW WILL HAVE RETURNED
TO ARKANSAS AND HELP MOISTURE LEVELS GRADUALLY INCREASE...ALTHOUGH
SOME SW TO W FLOW COULD KEEP THIS AT BAY WITH A HOT AND DRY AIR MASS
OVER TEXAS. MODELS ARE OVERALL IN GOOD AGREEMENT. TEMPERATURES WILL
REMAIN IN THE MID TO UPPER 90S...WITH SOME AROUND 100 DEGREES. HEAT
INDEX VALUES WILL BE CLOSE TO ADVISORY CRITERIA.

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

.DAY ONE...TODAY AND TONIGHT

AFTERNOON HEAT INDEX VALUES WILL RANGE FROM 98 TO 105 THIS
AFTERNOON. ELEVATED HEAT STRESS CONDITIONS WILL BE MAXIMIZED BETWEEN
2 AND 7 PM.

WILDFIRE DANGER WILL REMAIN A CONCERN ACROSS THE REGION...AS THE
LACK OF SIGNIFICANT RAINFALL WILL ONLY WORSEN THE ALREADY DRY GROUND
CONDITIONS. ANY FIRE THAT STARTS COULD SPREAD RAPIDLY...AND QUICKLY
GET OUT OF CONTROL.

A COLD FRONT WILL MOVE INTO NORTHEAST ARKANSAS THIS EVENING. THERE
IS A SMALL CHANCE A THUNDERSTORM MAY DEVELOP AHEAD OF THE FRONT. DUE
TO THE HOT TEMPERATURES...ANY STORM THAT DEVELOPS HAS THE POTENTIAL
TO PRODUCE DAMAGING WINDS. THE MAIN AREA OF CONCERN IS NORTHEAST OF
A LINE FROM JASPER...TO CLINTON...TO CLARENDON...AND WILL LAST FROM
THE AFTERNOON HOURS UNTIL SHORTLY AFTER SUNSET.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY

HIGH WILDFIRE DANGER WILL CONTINUE ACROSS THE REGION...DUE TO THE
LACK OF SIGNIFICANT RAINFALL.

TEMPERATURES WILL CONTINUE TO BE HOT THIS WEEK...WITH THE WARMEST
DAYS LIKELY THURSDAY AND FRIDAY. THE WEAK COLD FRONT WILL BRING
SLIGHTLY COOLER READINGS FOR TUESDAY...BUT THE REST OF THE WEEK WILL
HAVE HIGHS IN THE UPPER 90S TO AROUND 100. THIS...COMBINED WITH THE
HIGH HUMIDITY...WILL LEAD TO HEAT INDEX VALUES RANGING FROM 100 TO
105 DEGREES DURING THE AFTERNOON HOURS. THESE CONDITIONS WILL
CONTINUE TO CREATE ELEVATED CONCERNS FOR HEAT RELATED ILLNESSES.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION IS NOT ANTICIPATED.
