AREA FORECAST DISCUSSION

1150 PM CDT FRI MAR 29 2013

.AVIATION...
CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM.
CONDITIONS WILL BE QUITE VARIABLE ACROSS THE REGION WITH
SCATTERED SHOWERS AND THUNDERSTORMS AFFECTING THE AREA
OVERNIGHT AND INTO SATURDAY MORNING. MVFR TO IFR CONDITIONS
WILL BE POSSIBLE IN THE SHOWERS AND THUNDERSTORMS. CONDITIONS
WILL IMPROVE SOME LATE SATURDAY MORNING BEFORE MORE SHOWERS
AND THUNDERSTORMS DEVELOP SATURDAY AFTERNOON AND EVENING.

&&

.PREV DISCUSSION... /ISSUED 932 PM CDT FRI MAR 29 2013/

DISCUSSION...

THE 00Z NAM REMAINS CONSISTENT WITH THE 18Z RUN IN SUGGESTING 2
MAIN AREAS OF CONVECTION DURING THE OVERNIGHT HOURS. BAND OF
STORMS ACROSS NORTHEAST OK FORCED BY WARM ADVECTION/ISENTROPIC
LIFT IS FORECAST TO EXPAND IN COVERAGE AND MOVE EAST...EVENTUALLY
AFFECTING NORTHWEST AR LATER. THE STORMS HAVE INCREASED IN
INTENSITY...BUT ELEVATED INSTABILITY IS WEAKER OVER EASTERN OK
THAN AREAS TO OUR WEST...SO THE SEVERE RISK FOR LARGE HAIL REMAINS
LIMITED AND ISOLATED.

ANOTHER AREA OF CONVECTION ALONG THE RED RIVER IS FORECAST TO
TRACK EAST AND WILL EVENTUALLY AFFECT SOUTHEAST OK LATER. THERE IS
ALSO SUGGESTION THAT THIS CLUSTER WILL ALSO EXPAND IN
COVERAGE TOWARD 12Z...POSSIBLY DUE TO UPPER IMPULSE EVIDENT ON WV
IMAGERY MOVING INTO THE SOUTHERN HI PLAINS.

I HAVE EXPANDED THE LIKELY POPS NORTHWARD TO INCLUDE MORE OF
NORTHEAST OK. TEXT PRODUCTS WILL BE OUT SHORTLY.

AVIATION...
CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM.
CEILINGS WILL BE WIDELY VARIED ACROSS THE AREA DURING THE
VALID PERIOD WITH MVFR CONDITIONS EXPECTED LATER TONIGHT
WITH SCATTERED SHOWERS AND THUNDERSTORMS AFFECTING MOST OF
THE TAF SITES THROUGH SATURDAY MORNING. CONDITIONS WILL IMPROVE
LATE SATURDAY MORNING INTO SATURDAY AFTERNOON.

PREV DISCUSSION... /ISSUED 403 PM CDT FRI MAR 29 2013/

DISCUSSION...
WEAK SURFACE BOUNDARY LYING ACROSS THE FORECAST AREA WILL BECOME
MORE DIFFUSE WITH TIME BUT WILL BE THE FOCUS FOR SHOWER AND
THUNDERSTORM DEVELOPMENT TONIGHT INTO SATURDAY MORNING AS AN UPPER
LEVEL IMPULSE MOVES ACROSS THE AREA. ANOTHER WEAK FRONTAL BOUNDARY
WILL MOVE SOUTH INTO THE AREA SATURDAY NIGHT WITH SCATTERED
SHOWERS AND THUNDERSTORMS LIKELY TO DEVELOP IN ITS VICINITY AS
WELL. THERE WILL BE A HAIL THREAT WITH SOME OF THE STORMS TONIGHT
THROUGH SATURDAY NIGHT. STORM CHANCES SUNDAY SHOULD REMAIN
CONFINED TO SOUTHEAST OKLAHOMA AND WEST CENTRAL ARKANSAS.

A MUCH STRONGER AND UNSEASONABLY STRONG COLD FRONT WILL MOVE SOUTH
ACROSS THE AREA LATE SUNDAY NIGHT AND MONDAY MORNING. AREAS OF
RAIN ARE LIKELY TO DEVELOP BEHIND THE FRONT DURING THE DAY MONDAY
BEFORE ENDING MONDAY EVENING. BELIEVE THE NAM IS OVERDONE IN
SHOWING WINTRY WEATHER POTENTIAL GIVEN FIRST OF APRIL
CLIMATOLOGY...BUT DO BELIEVE THAT THE MUCH COLDER NAM SURFACE
TEMPERATURES ARE AT LEAST CLOSER TO REALITY THAN THE OTHER MODELS
INCLUDING THE ECMWF.

THE ECMWF DEPICTS A STRONGER UPPER SYSTEM MOVING ACROSS THE AREA
DURING THE MIDDLE PART OF NEXT WEEK THAN ALL OTHER MODELS. GIVEN
THAT THE UKMET IS NOT ONBOARD WITH THE ECMWF SOLUTION...PREFER TO
SIDE WITH THE CONSENSUS AT THIS TIME AND KEEP IT DRY BUT STILL
COOL FOR EARLY APRIL. A ROBUST WARMING TREND WILL BEGIN NEXT
FRIDAY AND CONTINUE INTO THE FOLLOWING WEEKEND.

WENT NEAR OR ABOVE GUIDANCE TEMPERATURES THE NEXT COUPLE DAYS.

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

.DAY ONE...TONIGHT.

SEVERE THUNDERSTORM.
	RISK...LIMITED.
	AREA...EASTERN OKLAHOMA.
	ONSET...ONGOING.

FLASH FLOOD.
	RISK...LIMITED.
	AREA...EASTERN OKLAHOMA.
	ONSET...TONIGHT.

HEAVY RAIN.
	RISK...LIMITED.
	AREA...EASTERN OKLAHOMA.
	ONSET...TONIGHT.

DISCUSSION...

THUNDERSTORMS ARE INCREASING IN COVERAGE OVER NORTHEAST OKLAHOMA
THIS EVENING AS WARM ADVECTION STRENGTHENS. THE STORMS ARE FORECAST
TO GRADUALLY INCREASE IN COVERAGE AND SPREAD EAST EVENTUALLY INTO
NORTHWEST ARKANSAS TOWARD MORNING. ANOTHER CLUSTER OF THUNDERSTORMS
DOWN NEAR THE RED RIVER IS EXPECTED TO EXPAND IN COVERAGE AND SPREAD
EAST DURING THE OVERNIGHT AND EVENTUALLY AFFECT SOUTHEAST OK.
ELEVATED INSTABILITY AND SHEAR ARE GREAT ENOUGH TO WARRANT A LIMITED
RISK OF SEVERE HAIL TO THE SIZE OF HALF DOLLARS. SOME LOCALLY HEAVY
RAIN IS ALSO POSSIBLE AS THE STORMS GROW INTO CLUSTERS AND MOVE
ACROSS THE REGION TONIGHT. HOWEVER...A SIGNIFICANT FLOOD RISK IS NOT
EXPECTED.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
LOCAL SPOTTER ACTIVATION MAY BE NEEDED.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY.
SATURDAY AND SUNDAY...THUNDERSTORM POTENTIAL.
MONDAY...HIGH WIND POTENTIAL.
TUESDAY THRU THURSDAY...NO HAZARDS.

EXTENDED DISCUSSION...

INSTABILITY WILL BE GREATER ON SATURDAY...HOWEVER THE LACK OF A
FOCUSING MECHANISM WILL KEEP THE THREAT FOR SEVERE WEATHER MORE
ISOLATED. THE COMBINATION OF NORTHWESTERLY SHEAR AND STRONG
INSTABILITY DOES WARRANT A LIMITED TO LOW END ELEVATED RISK OF
SEVERE STORMS MAINLY OVER FAR EASTERN OKLAHOMA INTO WESTERN
ARKANSAS. THE POTENTIAL FOR VERY LARGE HAIL IN EXCESS OF 2 INCHES
IN DIAMETER EXISTS.

A CHANCE OF THUNDERSTORMS WILL CONTINUE MAINLY ALONG AND SOUTH OF
INTERSTATE 40 ON SUNDAY.

A STRONG COLD FRONT WILL ARRIVE MONDAY MORNING AND WILL BE
ACCOMPANIED BY STRONG NORTH WINDS.
