Area forecast discussion, Jul 3, 2:38 PM CDT, 1 hour 10 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
238 PM CDT SUN JUL 3 2011

.DISCUSSION...

ERN OK AND NW AR ARE SANDWICHED BETWEEN 2 MID LVL RIDGES...ONE
CENTERED NEAR THE FOUR CORNERS...AND ANOTHER OVER THE LOWER
MISSISSIPPI VALLEY. A SUBTLE SHORTWAVE TROUGH IS NOTED ON WV
IMAGERY MOVING SOUTHEAST ACROSS THE CENTRAL PLAINS...WHILE A WEAK
FRONTAL BOUNDARY IS DRAPED ACROSS KS/MO. TO THE SOUTH OF THE
FRONT...A HOT AND DEEPLY MIXED LOW LVL ENVIRONMENT PREVAILS...WITH
TEMPS SOARING INTO THE UPPER 90S AND LOW 100S. DEWPOINTS HAVE
MIXED DOWN INTO THE UPPER 50S AND LOW 60S AND THUS HAVE MITIGATED
ANY ISSUES WITH THE HEAT INDEX. POPCORN SHOWERS AND STORMS HAVE
DEVELOPED OVER THE HIGHER TERRAIN OF NW AR AND SE OK...AND THIS
ACTIVITY WILL DIE OFF AS THE SUN SETS THIS EVENING.

THERE COULD BE SOME SCT SHOWERS AND STORMS IN ASSOCIATION WITH THE
FRONT THIS EVENING AS IT DROPS SOUTH FROM KS...OTHERWISE MOST
AREAS WILL REMAIN DRY. THE CENTRAL PLAINS SHORTWAVE AND DECAYING
FRONTAL BOUNDARY WILL BE OVER ERN OK AND NW AR ON MONDAY...AND
THUS THERE WILL BE AT LEAST SOME CHANCE OF MAINLY AFTERNOON
SHOWERS AND STORMS OVER MUCH OF THE FORECAST AREA. THE BETTER
CHANCES FOR AFTERNOON SHOWERS AND STORMS WILL SHIFT TO THE SOUTH
AND EAST ON TUESDAY.

ANOTHER FRONTAL BOUNDARY IS EXPECTED TO MAKE A RUN AT US LATE
WEDNESDAY INTO THURSDAY. THIS BOUNDARY WILL LIKELY TAKE SEVERAL
DEGREES OFF THE HIGHS AND WILL BRING MOST LIKELY THE BEST CHANCES
FOR RAIN FOR THIS UPCOMING WEEK. MODELS SUGGEST THERE COULD BE
SOME MCS ACTIVITY AS WELL IN A WEAK NWRLY FLOW ALOFT.

RAIN CHANCES GENERALLY DECREASE NEXT WEEKEND AS THE MID LVL RIDGE
REFORTIFIES SOME OVER THE SOUTHERN PLAINS. HOWEVER...SOME ISOLATED
AFTERNOON HIGHER TERRAIN SHOWERS AND STORMS STILL APPEAR
POSSIBLE...AND SOME LOW POPS WERE INSERTED IN THE EASTERN AREAS AS
A RESULT. TEMPERATURES WILL ALSO REBOUND BACK INTO THE UPPER 90S
TO NEAR 100 NEXT WEEKEND.

THIS OUTLOOK IS FOR NORTHWEST AND WEST CENTRAL ARKANSAS AS WELL AS
MUCH OF EASTERN OKLAHOMA.

.DAY ONE...TODAY AND TONIGHT.

SEVERE THUNDERSTORM.
	RISK...LIMITED.
	AREA...MAINLY NORTHWEST ARKANSAS AND FAR NORTHEAST OKLAHOMA.
	ONSET...3 PM.

DANGEROUS HEAT.

	ONSET...ONGOING.

DISCUSSION...
TEMPERATURES WILL AGAIN REACH 100 TO 104 DEGREES ACROSS MUCH OF
EASTERN OKLAHOMA AND WEST CENTRAL ARKANSAS THIS AFTERNOON. HEAT
INDEX VALUES WILL CLOSELY MIRROR TEMPERATURES DUE TO LOW HUMIDITY
LEVELS AND REMAIN SHORT OF 105.

ISOLATED TO WIDELY SCATTERED LATE AFTERNOON THUNDERSTORMS ARE
POSSIBLE THIS AFTERNOON MOST ANYWHERE...THOUGH THE HIGHER TERRAIN
AREAS OF NORTHWEST ARKANSAS WILL BE THE MOST FAVORED AREA FOR
DEVELOPMENT. WHILE THEY WILL BE SHORT LIVED...ANY THUNDERSTORM
THAT CAN DEVELOP WOULD HAVE THE POTENTIAL TO PRODUCE DAMAGING
DOWNBURST WINDS.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
SPOTTER ACTIVATION NOT ANTICIPATED DUE TO THE ISOLATED NATURE OF
THE SEVERE WEATHER THREAT.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY.
MONDAY THROUGH TUESDAY...THUNDERSTORM POTENTIAL...DANGEROUS HEAT
POTENTIAL.
WEDNESDAY THROUGH FRIDAY...THUNDERSTORM POTENTIAL.
SATURDAY...NO HAZARDS.

EXTENDED DISCUSSION...
THE MASSIVE UPPER RIDGE OVER THE SOUTHERN STATES MAY BUCKLE
JUST ENOUGH TO ALLOW A WEAK FRONTAL BOUNDARY TO REACH NORTHEAST
OKLAHOMA AND NORTHWEST ARKANSAS MONDAY. OTHERWISE...SMALL CHANCES
OF THUNDERSTORMS THE NEXT SEVERAL DAYS WILL DEPEND ON OUTFLOW
BOUNDARIES FROM CONVECTIVE ACTIVITY IN KANSAS OR MISSOURI OR
ISOLATED...PRIMARILY TERRAIN INDUCED STORMS. TEMPERATURES WILL
REMAIN HOT THROUGH AT LEAST EARLY NEXT WEEK.
