AND THE HIGHEST CHANCES WILL BE MOSTLY ACROSS THE SOUTHEAST 2/3 OR SO OF OUR AREA... WITH SOME DAY-TO-DAY VARIATIONS. RAIN CHANCES SLOWLY DECREASE INTO EARLY NEXT WEEK AS THE FORCING WEAKENS. HIGH PRESSURE MAY BE FORCEFUL ENOUGH TO SHUT OFF THE RAIN BY MID- WEEK. TEMPERATURES WILL DROP SIGNIFICANTLY WITH THE PASSAGE OF THE COLD FRONT TONIGHT AND TOMORROW. THE EXPECTED RAIN BAND ALONG/NORTHWEST OF THE FRONT WILL FURTHER COOL TEMPERATURES TOMORROW. AS A RESULT... THURSDAY WILL BE A CHILLY DAMP DAY FOR THE MOST PART ACROSS ABOUT THE SOUTHEAST HALF OF OUR AREA.

THIS HAZARDOUS WEATHER OUTLOOK COVERS NORTHERN...WESTERN...
CENTRAL...AND SOUTHERN OKLAHOMA...AND WESTERN NORTH TEXAS.
.DAY ONE...THIS AFTERNOON AND TONIGHT...
THUNDERSTORM OUTLOOK...
THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER WESTERN NORTH
TEXAS AND MUCH OF CENTRAL AND WESTERN OKLAHOMA.
LOCATION...
THE SLIGHT RISK AREA IS GENERALLY NORTHWEST OF A LINE FROM
HOLDENVILLE TO MARIETTA...AND SOUTHEAST OF AN ERICK TO WOODWARD
LINE.
TIMING...
THE MOST LIKELY TIME FOR SEVERE THUNDERSTORMS WILL BE AFTER 5 PM.
IMPACTS...
THE MAIN IMPACTS WILL BE VERY LARGE HAIL... POSSIBLY LARGER THAN
BASEBALLS. DAMAGING STRAIGHT LINE WINDS... HEAVY RAIN... AND
ISOLATED TORNADOES ALSO WILL BE POSSIBLE.
RECOMMENDED ACTIONS...
STORM SPOTTER GROUPS AND EMERGENCY MANAGEMENT PERSONNEL ACROSS THE
RISK AREA SHOULD BE PREPARED FOR SEVERE WEATHER OPERATIONS FROM LATE
AFTERNOON THROUGH THE EVENING.
DISCUSSION...
A WARM AND VERY UNSTABLE AIR MASS WILL REMAIN IN PLACE OVER OKLAHOMA
AND WESTERN NORTH TEXAS TODAY. ELEVATED SHOWERS AND SCATTERED
THUNDERSTORMS WERE DEVELOPING AT MIDDAY FROM FAR SOUTHWESTERN
OKLAHOMA... SOUTH AND SOUTHWESTWARD ACROSS TEXAS TOWARD THE BIG BEND
AREA. THESE SHOWERS WERE MOVING RAPIDLY NORTHEASTWARD. SURFACE
HEATING AND DESTABILIZATION WILL ALLOW SOME OF THESE SHOWERS AND
STORMS TO INTENSIFY AS THEY BECOME ROOTED MORE IN THE SURFACE AIR
LATER THIS AFTERNOON. WITH EXTREMELY UNSTABLE CONDITIONS ALREADY IN
PLACE... CAPE VALUES IN THE RANGE OF 3000 TO 4000... A FEW OF THESE
STORMS MAY BECOME SEVERE BY LATE AFTERNOON AS THEY MOVE ACROSS NORTH
CENTRAL TEXAS AND TOWARD CENTRAL OKLAHOMA. VERY LARGE HAIL WILL BE
THE MAIN CONCERN.
OTHER THUNDERSTORMS ARE LIKELY TO FORM LATE IN THE DAY... MOST
LIKELY BETWEEN 5 AND 7 PM... ALONG A COLD FRONT OVER NORTHWESTERN
OKLAHOMA... AND SOUTHWARD ALONG A DRY LINE INTO FAR WESTERN PARTS OF
NORTH TEXAS. VERTICAL WIND SHEAR WILL SUPPORT ORGANIZED SEVERE
THUNDERSTORMS... INCLUDING SUPERCELLS. THE EXTREME INSTABILITY
PRESENT WILL SUPPORT THE GENERATION OF VERY LARGE HAIL... BUT
DAMAGING WINDS AND A FEW TORNADOES ALSO WILL BE POSSIBLE. THE
COMBINATION OF SHEAR AND INSTABILITY... AND THE PRESENCE OF A
SURFACE BOUNDARY NEARBY... WILL PLACE THE AREA FROM WEST CENTRAL
INTO NORTH CENTRAL OKLAHOMA IN THE GREATEST RISK OF GIANT HAIL AND
ISOLATED TORNADOES LATE TODAY AND THIS EVENING.
THE STORMS ARE EXPECTED TO GRADUALLY EVOLVE INTO A LARGER COMPLEX OF
STORMS... WHICH WILL MOVE SOUTHEASTWARD WITH THE COLD FRONT
OVERNIGHT. LARGE HAIL...DAMAGING WINDS...AND HEAVY RAIN WILL BE THE
MAIN THREATS WITH THESE STORMS.
PROBABILITY TABLE...
VALID THROUGH 700 AM CDT THURSDAY MAY 13.
PROBABILITY OF THUNDERSTORMS OCCURRING IN THE
NWS NORMAN COUNTY WARNING AREA...100 PERCENT.
PROBABILITY OF SEVERE STORMS IF STORMS OCCUR..80 PERCENT.
OTHER HAZARDOUS WEATHER...
NONE.
.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY...
THUNDERSTORM OUTLOOK...
THUNDERSTORM CHANCES WILL REMAIN HIGH THURSDAY AND FRIDAY AS THE
FRONTAL BOUNDARY MOVES SLOWLY SOUTHWARD. ALTHOUGH THE SEVERE WEATHER
THREAT WILL DECREASE...THE THREAT FOR HEAVY RAIN WILL CONTINUE IN
SOUTHWEST AND CENTRAL OKLAHOMA THURSDAY...SHIFTING INTO SOUTHERN
OKLAHOMA AND WESTERN NORTH TEXAS FRIDAY AND POSSIBLE SATURDAY.
CHANCES FOR THUNDERSTORM WILL DECREASE BY EARLY NEXT WEEK AS THE
UPPER LEVEL TROUGH OVER THE ROCKIES GRADUALLY MOVES EASTWARD THROUGH
THE CENTRAL U.S.
OTHER HAZARDOUS WEATHER...
NONE.
THE NEXT SCHEDULED HAZARDOUS WEATHER OUTLOOK WILL BE ISSUED BY 5 AM
THURSDAY.In the hours before
