THIS HAZARDOUS WEATHER OUTLOOK COVERS NORTHERN...WESTERN...
CENTRAL...AND SOUTHERN OKLAHOMA...AND WESTERN NORTH TEXAS.
.DAY ONE...THIS AFTERNOON THROUGH TONIGHT...
THUNDERSTORM OUTLOOK...
A FEW STRONG THUNDERSTORMS ARE POSSIBLE TONIGHT.
DISCUSSION...
STRENGTHENING SOUTHERLY LOW LEVEL WINDS WILL TRANSPORT RICH GULF
MOISTURE NORTHWARD ACROSS THE SOUTHERN PLAINS THROUGH TONIGHT. AS
THIS OCCURS THE PROBABILITY FOR SHOWERS AND THUNDERSTORMS WILL
INCREASE. THROUGH THE DAYTIME HOURS INSTABILITY WILL REMAIN LIMITED
AND SEVERE WEATHER IS NOT ANTICIPATED... ALTHOUGH SMALL HAIL AND
CLOUD TO GROUND LIGHTNING WILL BE POSSIBLE WITH SOME STORMS.
A LOW LEVEL JET WILL DEVELOP TONIGHT... WHICH WILL AID IN DEVELOPING
A WARM... BUT MOIST ELEVATED LAYER ABOVE THE COOL STABLE AIRMASS AT
THE SURFACE. THIS WILL RESULT IN INCREASING INSTABILITY ABOVE THE
SURFACE AND IN THE DEVELOPMENT OF ELEVATED THUNDERSTORMS ACROSS
OKLAHOMA AND NORTH TEXAS OVERNIGHT. A FEW OF THESE STORMS WILL BE
CAPABLE OF PRODUCING MARGINALLY SEVERE HAIL.
PROBABILITY TABLE...
VALID THROUGH 700 AM CDT MONDAY MAY 10.
PROBABILITY OF THUNDERSTORMS OCCURRING IN THE
NWS NORMAN COUNTY WARNING AREA...100 PERCENT
PROBABILITY OF SEVERE STORMS IF STORMS OCCUR...20 PERCENT.
OTHER HAZARDOUS WEATHER...
NONE.
.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY...
THUNDERSTORM OUTLOOK...
A SMALL... BUT WELL DEFINED UPPER LEVEL DISTURBANCE WILL EJECT FROM
THE SOUTHERN ROCKIES ON MONDAY...PRODUCING A DEEP SURFACE LOW THAT
WILL LIKELY TRACK ACROSS KANSAS. THE LOW WILL DRAG A DRYLINE
INTO OKLAHOMA AND WESTERN NORTH TEXAS...MOST LIKELY BY EARLY
AFTERNOON. BY THAT TIME...RICH GULF MOISTURE WILL BE TRANSPORTED
INTO THE REGION AHEAD OF THE DRYLINE. ALTHOUGH A STRONG CAP WILL BE
IN PLACE...LIFTING ALONG THE DRYLINE SHOULD BE SUFFICIENT TO PRODUCE
THUNDERSTORMS MONDAY AFTERNOON AND EVENING. INSTABILITY AND WIND
SHEAR ARE FORECAST TO BE MORE THAN ADEQUATE FOR SUPERCELL
STORMS...CAPABLE OF PRODUCING VERY LARGE HAIL... DAMAGING WIND GUSTS
AND TORNADOES. CURRENTLY...THE GREATEST COVERAGE OF STORMS
IS FORECAST IN NORTHERN OKLAHOMA...BUT ISOLATED CELLS...EQUALLY
SEVERE...COULD FORM DOWN THE DRYLINE INTO WESTERN AND CENTRAL
OKLAHOMA...AND WESTERN NORTH TEXAS.
SEVERE THUNDERSTORMS ON MONDAY AFTERNOON AND EVENING...MAY MOVE AT
SPEEDS GREATER THAN 45 MPH...LEAVING LITTLE TIME FOR PEOPLE TO REACT
TO WARNINGS. YOU ARE ENCOURAGED TO THINK AHEAD TO WHERE YOU WILL BE
ON MONDAY...HOW YOU WILL RECEIVE WEATHER WARNINGS...AND WHERE YOU
WILL SHELTER IF A STORM APPROACHES YOUR LOCATION.
THE WEATHER SYSTEM ARRIVING MONDAY WILL LEAVE A FRONTAL BOUNDARY
STALLED SOMEWHERE ACROSS THE SOUTHERN PLAINS. FROM MID TO LATE
WEEK...ADDITIONAL UPPER LEVEL DISTURBANCES WILL INTERACT WITH THE
FRONT...MAINTAINING A CHANCE OF SEVERE STORMS...AND AN INCREASING
CHANCE OF HEAVY RAINFALL.
OTHER HAZARDOUS WEATHER...
VERY STRONG WINDS...WITH POTENTIALLY DAMAGING GUSTS...MAY OCCUR WEST
OF THE DRYLINE ON MONDAY AFTERNOON.
THE NEXT SCHEDULED HAZARDOUS WEATHER OUTLOOK WILL BE ISSUED BY 5 AM
MONDAY.
