AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE NORMAN OK 1015 PM CDT SUN MAY 7 2006 UPDATE FOR RADAR FAILURES... KTLX WAS TAKEN DOWN EARLIER THIS EVENING TO PERFORM MANDATORY MAINTENANCE TO AVOID FAILURE OF THE RADAR AT A MORE CRUCIAL TIME TONIGHT. TECHNICIANS ARE AT THE SITE WITH HOPES OF MAINTENANCE BEING COMPLETED BY MIDNIGHT. KFDR RECENTLY CRASHED DUE TO A KLYSTRON CURRENT FAILURE. MAINTENANCE HAS BEEN NOTIFIED...BUT IT IS UNKNOWN WHEN THE RADAR WILL BE BACK IN SERVICE. JAMES ----------------------- 925 PM CDT SUN MAY 7 2006 A WEAKENING LINE OF CONVECTION CONTINUES TO EXPAND SOUTHEASTWARD FROM GREAT BAND KANSAS INTO THE SOUTHWEST CORNER OF THE STATE WITH THESE STORMS PAST THEIR PEAK INTENSITY...WITH AN ISOLATED SUPERCELL SOUTHEAST OF GUYMON. CONVECTIVE INDICES AND REGIONAL RAOBS SHOW A SHARP DROP OFF IN CONVECTIVE POTENTIAL EAST OF THE TEXAS PANHANDLE WITH THE OUN SOUNDING DEPICTING A 6 DEGREE C INVERSION AT 820 MB. SHORTWAVE TROUGH CONTINUES TO APPROACH THE AREA AND HIGHER BASED MOISTURE SHOULD BE TRANSPORTED NORTHWARD WITH THE LOW LEVEL JET SO SOME MODIFICATION IS EXPECTED OVERNIGHT BUT JUST HOW MUCH REMAINS TO BE SEEN. STORMS WILL SOON MOVE INTO NORTHWEST OKLAHOMA WITH THESE STORMS EXPECTED TO CONTINUE A WEAKENING TREND. OTHER STORMS ARE EXPECTED TO BEGIN DEVELOPING SOUTHWARD INTO THE TEXAS PANHANDLE THIS EVENING AS THE LOW LEVEL JET DEVELOPS...WITH THESE STORMS EVENTUALLY ENTERING SOUTHWEST SECTIONS OF THE AREA. STEEP LAPSE RATES AND GREATER SHEAR WARRANTS THE MENTION OF SLIGHT RISK FOR THESE AREAS. IF STORMS BECOME TOO NUMEROUS NEAR SAN ANGELO HOWEVER...STORM COVERAGE MAY BE RESTRICTED FARTHER NORTH. WILL BE LOWERING POPS A BIT MORE ACROSS EASTERN SECTIONS OF THE AREA TONIGHT WHERE CIN IS SO HIGH THAT IS SEEM UNLIKELY THAT THEY WILL RECEIVE ANY PRECIPITATION...AND IF THEY DO...MAINLY HIGH BASED DEVELOPMENT WITH LOW QPF SEEMS MOST LIKELY. JAMES ------------------------ 308 PM CDT SUN MAY 7 2006 .DISCUSSION... LOW CLOUD COVER HARD TO GET RID OF ACROSS MOST AREAS TODAY...BUT WESTERN AND SOUTHERN SECTIONS ARE EXPECTED TO SEE A PERIOD OF AT LEAST PARTIAL SUN BEFORE IT SETS. LEAST LIKELY AREA FOR CLEARING WILL BE CENTRAL/NORTH-CENTRAL ZONES. WEAK WAVE WILL APPROACH REGION THIS EVENING AND OVERNIGHT...AND WITH RELATIVELY DEEP/RICH MOISTURE IN PLACE OR INCREASING IN WEAKLY CAPPED ENVIRONMENT...SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS STILL EXPECTED OVERNIGHT THROUGH TOMORROW MORNING. LIKELY POPS WERE RETAINED AND REORIENTED SLIGHTLY BASED ON NEW MODEL DATA. RUN TO RUN CONSISTENCY OF SHORT TERM MODELS AIDS IN ENOUGH CONFIDENCE TO KEEP THESE HIGHER POPS. SEVERE POTENTIAL WILL NOT BE ALL THAT HIGH...BUT IN NORTHWEST FLOW REGIME...ELEVATED SUPERCELL TYPE ACTIVITY CANNOT BE RULED OUT. BETTER SEVERE WEATHER PROSPECTS WILL BE NEAR DRY LINE TOMORROW ACROSS WESTERN ZONES WITH HIGH INSTABILITY...AND ESPECIALLY ON TUESDAY WITH STRONG FRONT/DRY LINE INTERACTION. LINGERING POST- FRONTAL RAIN POSSIBLE ON WEDNESDAY BEFORE DRIER AIR AND LOW- LEVEL RIDGING TAKES HOLD. WEAK WAVE IN NORTHWEST FLOW FORECASTED BY MOST MODELS FOR THURSDAY NIGHT INTO FRIDAY. MODEL TREND MAKING SENSE THAT FOCUS OF PRECIP WOULD MOST LIKELY AFFECT SOUTHWEST PORTIONS OF COUNTY WARNING AREA NEARER LOW LEVEL THETA-E GRADIENT. WILL ADD POPS ACROSS SOUTHWEST PORTIONS OF FORECAST AREA FOR THIS SCENARIO. THIS REGIME LASTS INTO THE FOLLOWING WEEK...BUT CONFIDENCE IN S/WV STRENGTH AND TIMING DECREASES WITH TIME. ALSO...LATEST RUN OF MEDIUM RANGE ALLOWING REINFORCING SHOT OF COOLER/DRIER AIR ON SATURDAY-SUNDAY. GIVEN UPPER PATTERN AND LARGE GREAT LAKES VORTEX...THIS SEEMS REASONABLE AND WILL KEEP TEMPS COOLER/DRIER INTO THE WEEKEND...ESPECIALLY CENTRAL AND EAST. && .PRELIMINARY POINT TEMPS/POPS...

THIS HAZARDOUS WEATHER OUTLOOK COVERS NORTHERN...WESTERN...
CENTRAL...AND SOUTHERN OKLAHOMA...AND WESTERN NORTH TEXAS.
.DAY ONE...THIS EVENING AND TONIGHT...
THUNDERSTORM OUTLOOK...
THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS THROUGH TONIGHT
ACROSS PORTIONS OF SOUTHWEST OKLAHOMA AND WESTERN NORTH TEXAS.
LOCATION...
MAINLY WEST OF A LINE FROM ERICK...TO LAWTON...DUNCAN...AND WAURIKA.
TIMING...
FROM 10 PM THROUGH OVERNIGHT.
IMPACTS...
GOLFBALL SIZE HAIL IS THE PRIMARY CONCERN WITH 60 MPH WINDS A
SECONDARY CONCERN.
RECOMMENDED ACTIONS...
STORM SPOTTER GROUPS AND EMERGENCY MANAGEMENT PERSONNEL ACROSS THE
RISK AREA SHOULD BE PREPARED FOR THE POSSIBILITY OF SEVERE WEATHER
OVERNIGHT.
DISCUSSION...
THUNDERSTORMS ARE EXPECTED TO INCREASE IN NUMBER AND INTENSITY
ACROSS THE TEXAS PANHANDLE THIS EVENING...BEFORE SPREADING INTO
SOUTHWEST OKLAHOMA AND WESTERN NORTH TEXAS OVERNIGHT. THE
COMBINATION OF MODERATE INSTABILITY AND SHEAR WILL SUPPORT THE
POTENTIAL FOR HIGH BASED SUPERCELLS WITH GOLFBALL SIZE HAIL
POSSIBLE. THE POTENTIAL ALSO EXISTS FOR STORMS TO EVENTUALLY MERGE
INTO ONE OR MORE CLUSTERS AS THEY MOVE SOUTHEASTWARD...WITH THE
LEADING EDGE OF STORMS POSSIBLY ACCOMPANIED BY 60 MPH WINDS.
OTHER LESS INTENSE STORMS ARE ALSO EXPECTED TO ORGANIZE ACROSS
KANSAS AND NORTHWEST OKLAHOMA. ALTHOUGH AN ISOLATED SEVERE STORM OR
TWO CAN NOT BE RULED OUT...WEAKER INSTABILITY AND SHEAR SHOULD ALLOW
STORMS TO GRADUALLY WEAKEN AS THEY MOVE INTO THE AREA.
PROBABILITY TABLE...
VALID THROUGH 700 AM CDT MONDAY MAY 8.
PROBABILITY OF THUNDERSTORMS OCCURRING IN THE
NWS NORMAN COUNTY WARNING AREA...100 PERCENT.
PROBABILITY OF SEVERE STORMS IF STORMS OCCUR...30 PERCENT.
OTHER HAZARDOUS WEATHER...
NONE.
.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY...
THUNDERSTORM OUTLOOK...
THUNDERSTORMS MAY BE ONGOING MONDAY MORNING IN SOUTHERN AND CENTRAL
OKLAHOMA WITH A LOW THREAT FOR HAIL AND STRONG WINDS. ATTENTION WILL
TURN TO FAR WESTERN OKLAHOMA AND WESTERN NORTH TEXAS MONDAY
AFTERNOON...ALONG A DEVELOPING DRYLINE. WITH A STRONG CAP...BUT ALSO
LARGE INSTABILITY...ISOLATED THUNDERSTORMS MAY FORM ALONG THE
DRYLINE. WIND SHEAR WOULD THEN BE FAVORABLE FOR A FEW SUPERCELLS
WITH POTENTIAL TO PRODUCE SEVERE WEATHER. A MORE POTENT SETUP FOR
WIDESPREAD THUNDERSTORMS...SOME POSSIBLY SEVERE...WILL DEVELOP LATE
TUESDAY INTO TUESDAY NIGHT...AS A DRYLINE...COLD FRONT...AND
STRENGTHENING UPPER LEVEL WINDS CONVERGE ON THE SOUTHERN PLAINS.
THUNDERSTORMS MAY PERSIST INTO WEDNESDAY...DEPENDING ON THE MOVEMENT
OF THE COLD FRONT. DRY AND STABLE HIGH PRESSURE WILL SETTLE OVER THE
AREA WEDNESDAY NIGHT...SIGNALING AN END TO THUNDERSTORM CHANCES FOR
THE REST OF THE WEEK.
OTHER HAZARDOUS WEATHER...
NONE.
THE NEXT SCHEDULED HAZARDOUS WEATHER OUTLOOK WILL BE ISSUED AT 7 AM
MONDAY MAY 7TH.
