AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
253 PM CDT MON MAY 8 2006

.DISCUSSION...
MAIN FORECAST CONCERNS IN THE SHORT TERM INVOLVE SEVERE WEATHER
POTENTIAL...ESPECIALLY LATE TUESDAY...AS WELL AS HEAVY RAIN
POTENTIAL IN THE FAR NORTH TONIGHT AND OVER MUCH OF THE AREA TUE NIGHT.

FEW ELEVATED STORMS CONTINUE ACROSS SE OKLAHOMA THIS AFTERNOON.
THERE REMAINS A SLIM CHANCE OF LARGE HAIL WITH THESE STORMS WHICH
SHOULD BE OUT OF THE AREA BY 00Z. BETTER SEVERE CHANCES WILL BE
WITH POTENTIAL MCS AFFECTING FAR NE OKLAHOMA AND NW ARKANSAS LATE
TONIGHT. 12Z MODELS OFFER A SURPRISINGLY SIMILAR SOLUTION OF
STORMS DEVELOPING ALONG DRYLINE IN WESTERN KANSAS LATE THIS
AFTERNOON THEN BLOSSOMING INTO MCS AFTER MIDNIGHT NEAR THE NOSE OF
45KT LOW LEVEL JET. THIS NOT ONLY WILL PROVIDE AMPLE SHEAR FOR A
FEW ELEVATED SEVERE STORMS...BUT LOW LEVEL MOISTURE TRANSPORT IS
IMPRESSIVE. ALTHOUGH THE HEAVIEST RAINFALL WILL LIKELY OCCUR JUST
TO OUR NORTH...6 HOUR FFG OF AROUND 2 INCHES NEAR THE KS BORDER.
WILL NOT ISSUE A WATCH AT THIS TIME BUT MAY ULTIMATELY NEED TO
INCLUDE A FEW COUNTIES ALONG THE KS BORDER AS MCS EVOLUTION
BECOMES MORE CERTAIN.

MCS WILL BE ONGOING EARLY TUESDAY MORNING AND WILL LEAVE AN
OUTFLOW BOUNDARY SOMEWHERE ACROSS EASTERN OK INTO WESTERN ARK. HOW
THIS PLAYS OUT WILL HAVE A LARGE BEARING ON SEVERE POTENTIAL TUE
AFTERNOON AND EVENING...BUT INSTABILITY WILL LIKELY BECOME VERY
IMPRESSIVE ACROSS MUCH OF THE AREA...ESPECIALLY SE OKLAHOMA. WARM
FRONT ALSO APPEARS TO BE REINFORCED OVER SE OKLAHOMA BY LATE
AFTERNOON. WHILE UPPER WINDS ARE LESS THAN IDEAL...SRH IN LOWEST
1KM NEAR SFC BOUNDARIES WOULD IMPLY A HIGH SEVERE POTENTIAL. WARM
SECTOR AIRMASS ACROSS SE WILL BE STRONGLY CAPPED BUT APPROACHING
UPPER WAVE SHOULD BE SUFFICIENT TO BREAK IT.

STORMS SHOULD DEVELOP INTO ANOTHER MCS TUE NIGHT WITH MORE SEVERE
POTENTIAL. ALSO BECOMING CONCERNED ABOUT HEAVY RAIN TUE NIGHT...
ESPECIALLY IF HEAVY RAIN FALLS IN SAME AREAS AS EXPECTED TONIGHT
AS PWAT VALUES WELL ABOVE CLIMO. SYNOPTIC COLD FRONT WILL PUSH
THROUGH BY EARLY WEDNESDAY AND END THE PRECIP FROM THE WEST. 12Z
GFS HAS TRENDED A LITTLE STRONGER WITH UPPER WAVE OVER THE MIDWEST
WED EVENING AND IF THIS CONTINUES SOME LOW POPS MAY BE NEEDED WED
EVENING IN THE NORTH.

MADE NO CHANGES TO THE EXTENDED FORECAST. DRY AND LITTLE COOLER
FOR THURSDAY...WITH THUNDERSTORM CHANCES RETURNING BY 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...SOUTH EAST OKLAHOMA AND WEST CENTRAL ARKANSAS.
	ONSET...ONGOING.

DISCUSSION...
THUNDERSTORMS WILL MOVE ACROSS SOUTHEASTERN OKLAHOMA DURING THE
EARLY AFTERNOON. WITH CONDITIONS BECOMING MORE UNSTABLE AS SURFACE
TEMPERATURES WARM... EXPECT TO SEE ISOLATED STRONG TO SEVERE
STORMS ACROSS THE SOUTHERN PORTION OF THE FORECAST AREA. THE MAIN
THREAT FROM THIS ACTIVITY WILL BE LARGE HAIL... BRIEF HEAVY
RAIN... AND FREQUENT LIGHTNING.

IN ADDITION...THUNDERSTORMS ARE EXPECTED TO DEVELOP BY LATE
AFTERNOON OVER PORTIONS OF WESTERN KANSAS SOUTHWARD INTO THE TEXAS
PANHANDLE. AS THE LOW-LEVEL JET STRENGTHENS TO 30 TO 40 KNOTS
DURING THE EVENING...THIS ACTIVITY WILL EVOLVE INTO A COMPLEX OF
STORMS AND DROP SOUTHEAST. THUNDERSTORMS SHOULD REACH PARTS OF
NORTHEAST OKLAHOMA AROUND MIDNIGHT AND MOVE INTO NORTHWEST
ARKANSAS AFTER 3 AM. WEAKER INSTABILITY IS FORECAST OVERNIGHT
ACROSS NORTHEAST OKLAHOMA AND NORTHWEST ARKANSAS...BUT MARGINALLY
SEVERE WINDS AND HAIL WILL BE POSSIBLE...ESPECIALLY IF A
SIGNIFICANT COLD POOL DEVELOPS WITH THE THUNDERSTORM COMPLEX.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
SPOTTER ACTIVATION MAY BE NEEDED FOR OVERNIGHT ACTIVITY.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY.
TUESDAY...SEVERE THUNDERSTORM POTENTIAL.
WEDNESDAY...THUNDERSTORM POTENTIAL.
THURSDAY...NO HAZARDS.
FRIDAY...NO HAZARDS.
SATURDAY...THUNDERSTORM POTENTIAL.
SUNDAY...NO HAZARDS.

EXTENDED DISCUSSION...
SEVERE WEATHER POTENTIAL FOR TUESDAY WILL HINGE ON THE IMPACT OF THE
MONDAY NIGHT THUNDERSTORM COMPLEX. A THUNDERSTORM OUTFLOW BOUNDARY
IS EXPECTED TO BE SOMEWHERE ACROSS THE AREA...LIKELY ACROSS SOUTHEAST
OKLAHOMA. THIS BOUNDARY COULD BE THE FOCUS FOR ADDITIONAL
THUNDERSTORMS DURING THE DAY. AS THE LOW-LEVEL JET STRENGTHENS...ONE
OR MORE THUNDERSTORM COMPLEXES MAY DEVELOP AND MOVE ACROSS THE AREA
TUESDAY EVENING AND OVERNIGHT. GIVEN THE STRONG WIND FIELDS AND
DEGREE OF INSTABILITY...SEVERE WEATHER APPEARS LIKELY.

QUIETER WEATHER IS EXPECTED FOR LATE IN THE WEEK AS SURFACE HIGH
PRESSURE MOVES INTO THE SOUTHERN PLAINS. THUNDERSTORM CHANCES RETURN
FOR THE WEEKEND AS A SURFACE BOUNDARY APPROACHES THE AREA.

EMERGENCY MANAGEMENT PLANNING STATEMENT...
EMERGENCY MANAGEMENT ORGANIZATIONS SHOULD PLAN ON AN ACTIVE SEVERE
WEATHER DAY FOR TUESDAY AND TUESDAY NIGHT.
