DISCUSSION...

MAIN CONCERNS THIS FORECAST CYCLE ARE CHANCES OF
CONVECTION...DIURNAL INITIALLY...THEN BETTER CHANCES WITH A
FRONTAL BOUNDARY THURSDAY TO FRIDAY. OVERALL LOW CHANCE OF SEVERE
STORMS. ON GOING HIGH WILD FIRE DANGER ACROSS ARKANSAS.

THIS AFTERNOON...ISOLATED CONVECTION HAS FORMED OVER WESTERN TO
SOUTHERN AR. SURFACE ANALYSIS HAS THE WEAK FRONT NEARLY
STATIONARY OVER SOUTH CENTRAL AR...JUST SOUTH OF KLIT...NORTH OF
KHOT...WHILE TO THE NW NEAR KFSM. DRIER AIR IS NW OF THE BOUNDARY
WITH MID 60S DEW POINTS...WHILE STILL 70S DEW POINT TEMPS SOUTH OF
THE BOUNDARY. ATMOSPHERE SOUTH OF THE BOUNDARY IS MORE MOIST AND
UNSTABLE...WHILE NORTH LESS. THE UPPER NW FLOW IS BRINGING SOME
SHORT WAVE ENERGY SW OVER OK TO FAR W AR...AND THESE STORMS SHOULD
MOVE SSE. QUITE DRY ALOFT AND STRONG DOWN BURST WINDS WOULD BE
BEST THREAT OF ANY STRONG STORM. AFTER SUNSET CONVECTION SHOULD
GRADUALLY WEAKEN AND DISSIPATE.

SHORT TERM...TONIGHT THROUGH FRIDAY NIGHT

WILL HAVE A SLIGHT CHANCE GOING THIS LATE AFTERNOON TO EVENING
OVER WEST...PARTS OF CENTRAL...AND TO SOUTHERN AR. ANY WHERE SOUTH
OF THE BOUNDARY WILL HAVE A CHANCE. THE FRONT IS EXPECTED TO SAG A
BIT MORE SOUTH TONIGHT...BUT STALL OVER SOUTH CENTRAL AR...BEFORE
SLOWLY LIFTING NORTH ON WEDNESDAY. MAINLY SLIGHT CHANCES OF
CONVECTION WEDNESDAY WITH THE WEAK FRONT AS IT LIFTS NORTH OVER
AR. THEN THURSDAY TO FRIDAY...A COLD FRONT WILL GRADUALLY MOVE
ACROSS THE STATE AND BRING BETTER CHANCES FOR CONVECTION. ISOLATED
STRONG TO SEVERE STORMS WILL BE POSSIBLE. LATER FRIDAY THE FRONT
IS EXPECTED TO GRADUALLY MOVE SE TO SOUTHERN PARTS OF AR AND THE
PRECIP WITH IT. THE UPPER TROUGH DEEPENS TO ALLOW THE FRONT TO SAG
THROUGH AS WELL AS MODERATING TEMPS. TEMPS REMAIN WARM AND AT OR
ABOVE NORMAL WEDNESDAY AND THURSDAY...THEN COOLING FRIDAY AND
INTO THE WEEKEND TO NORMAL TO A BIT BELOW NORMAL TEMPS. RAIN
AMOUNTS WILL AGAIN BE QUITE QUESTIONABLE. SOME LOCATIONS MAY
RECEIVE OVER AN INCH...WHILE MOST LESS THAN A QUARTER INCH OR LESS.

LONG TERM...SATURDAY THROUGH TUESDAY

UPPER HIGH PRESSURE WILL BE OVER THE FOUR CORNERS REGION TO BEGIN
THE PERIOD. AN UPPER LOW PRESSURE SYSTEM WILL BE EXITING THE GREAT
LAKES. NORTHWEST FLOW WILL REMAIN OVER ARKANSAS THROUGH THE PERIOD.

THE NORTHWEST FLOW ALOFT WILL BRING SEVERAL SHORT WAVES THROUGH
ARKANSAS THROUGH THE PERIOD. WILL BRING IN A SLIGHT CHANCE OF
SHOWERS AND THUNDERSTORMS SATURDAY NIGHT AS MOISTURE INCREASES IN
THE NORTH. RAIN CHANCES WILL SPREAD SOUTHWARD SUNDAY...AND WILL
BECOME AREA WIDE THROUGH THE REST OF THE PERIOD. HIGH TEMPERATURES
WILL GENERALLY BE IN THE MID 80S TO MID 90S...WITH LOWS IN THE MID
