THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF NORTHERN...
WESTERN...CENTRAL...AND SOUTHERN OKLAHOMA...AND WESTERN NORTH
TEXAS.

.DAY ONE...TODAY AND TONIGHT...

.THUNDERSTORMS...
THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS ALL OF
OKLAHOMA AND WESTERN NORTH TEXAS THROUGH TONIGHT.

TIMING...
STRONG TO SEVERE STORMS WILL BE POSSIBLE THROUGHOUT THE DAY
TODAY. THE MOST LIKELY TIME FOR SEVERE STORMS ACROSS NORTHERN
OKLAHOMA WILL BE BEFORE SUNRISE. STRONG TO SEVERE STORMS WILL THEN
BE POSSIBLE OVER CENTRAL OK FROM NOON TO 6 PM. THE LAST ROUND OF
STRONG TO SEVERE STORMS WILL LIKELY IMPACT SOUTHERN OKLAHOMA AND
WESTERN OKLAHOMA FROM AROUND 4 PM TO MIDNIGHT.

IMPACTS...
THE PRIMARY HAZARDS WILL BE HAIL UP THE SIZE OF HALF DOLLARS AND
WIND GUSTS NEAR 60 TO 70 MPH. LOCALIZED HEAVY RAINFALL MAY ALSO
LEAD TO FLASH FLOODING.

DISCUSSION...
A SMALL LINE OF THUNDERSTORMS IS CURRENTLY MAKING ITS WAY ACROSS
NORTH CENTRAL OKLAHOMA EARLY THIS MORNING. SEVERE WIND GUSTS HAVE
BEEN OBSERVED WITH THIS LINE AND WILL LIKELY CONTINUE THROUGH
SUNRISE ACROSS NORTHERN OKLAHOMA. OTHER THUNDERSTORMS WERE
DEVELOPING JUST NORTHWEST OF THE OKLAHOMA CITY METRO THIS MORNING.
AT LEAST SMALL HAIL UP TO THE SIZE OF NICKELS WILL ACCOMPANY THESE
STORMS AS THEY LIFT NORTHEASTWARD INTO THE I35 CORRIDOR. IT IS
UNCLEAR HOW MANY STORMS WILL DEVELOP THIS AFTERNOON AND EVENING...BUT
AN OUTFLOW BOUNDARY FROM THE EARLY MORNING ACTIVITY WILL LIKELY
REMAIN THE FOCUS NEAR THE I40 AND I44 CORRIDORS ACROSS CENTRAL
OKLAHOMA.

ADDITIONAL DEVELOPMENT WILL THEN BE POSSIBLE THROUGH THE OVERNIGHT
HOURS MAINLY ALONG AND SOUTH OF I40 AS AN UPPER LEVEL STORM SYSTEM
APPROACHES.

.SPOTTER AND EMERGENCY MANAGEMENT STATEMENT...
STORM SPOTTER GROUPS AND EMERGENCY MANAGEMENT PERSONNEL ACROSS
THE RISK AREA SHOULD BE PREPARED FOR SEVERE WEATHER OPERATIONS
THROUGH TONIGHT.

.HEAVY RAINFALL...
ANY OF THE THUNDERSTORMS WILL HAVE THE POTENTIAL FOR HEAVY
RAINFALL THAT COULD LEAD TO LOCALIZED FLOODING. THE RISK FOR
FLOODING WILL BE GREATEST WHERE HEAVY RAINFALL HAS FALLEN
RECENTLY.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY...

.THUNDERSTORMS...
STRONG THUNDERSTORMS WILL REMAIN POSSIBLE THROUGH WEDNESDAY...
ALTHOUGH THE RISK FOR WIDESPREAD SEVERE WEATHER WILL REMAIN LOW.
THUNDERSTORM CHANCES WILL SLOWLY SHIFT SOUTHWARD THURSDAY THROUGH
SUNDAY. SMALL HAIL...STRONG WIND GUSTS...AND LOCALIZED FLOODING
WILL REMAIN POSSIBLE.
