THUNDERSTORM OUTLOOK
NATIONAL WEATHER SERVICE OKLAHOMA CITY OK
630 AM CDT FRI MAY 26 1995

THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS MAINLY TONIGHT
OVER WESTERN PORTIONS OF OKLAHOMA AND NORTH TEXAS. THE AREA IS GENERALLY
WEST OF A LINE FROM CHEROKEE OKLAHOMA TO HENRIETTA TEXAS. THERE IS ALSO
A SLIGHT RISK OF SEVERE THUNDERSTORMS TODAY AND TONIGHT FOR PORTIONS OF
CENTRAL AND SOUTHERN OKLAHOMA EAST OF THE MODERATE RISK AREA AND WEST OF
A PONCA CITY TO HOLDENVILLE TO CLAYTON LINE.

A WARM FRONT EXTENDED FROM A LOW IN SOUTHWEST TEXAS NORTHEASTWARD INTO
NORTHEAST TEXAS THIS MORNING. TO THE NORTH OF THE WARM FRONT A
RELATIVELY SHALLOW LAYER OF COOL AIR REMAINED OVER MUCH OF OKLAHOMA AND
WESTERN PARTS OF NORTH TEXAS. ABOVE THIS SHALLOW COOL AIRMASS SOUTHERLY
WINDS ARE BRINGING WARM MOIST NORTHWARD. SCATTERED THUNDERSTORMS WILL
CONTINUE TO DEVELOP TODAY AS THE WARM MOIST AIR RIDES UP OVER THE
SHALLOW COOL AIRMASS. ALTHOUGH THE MAIN THREAT FROM THESE STORMS WILL BE
HEAVY RAINFALL...SOME OF THESE THUNDERSTORMS COULD PRODUCE LARGE HAIL.

AN UPPER LEVEL STORM SYSTEM OVER THE SOUTHWEST U.S. WILL MOVE
NORTHEASTWARD TODAY AND TONIGHT. AS THIS SYSTEM APPROACHES THE WARM
FRONT IS EXPECTED TO LIFT NORTHWARD ALLOWING WARMER AND MORE UNSTABLE
AIR TO SPREAD NORTHWARD OVER THE AREA.  THUNDERSTORMS ARE EXPECTED
TO DEVELOP NEAR THE DRY LINE IN WEST TEXAS THIS AFTERNOON AND MOVE INTO
WESTERN SECTIONS OF OKLAHOMA AND NORTH TEXAS LATE THIS AFTERNOON
TONIGHT. WIND PROFILES WILL BE FAVORABLE FOR SUPERCELL DEVELOPMENT IN
THE MODERATE RISK AREA LATE THIS AFTERNOON AND TONIGHT. LARGE
HAIL...DAMAGING WINDS AND ISOLATED TORNADOES WILL BE POSSIBLE.

SPOTTER GROUPS IN THE RISK AREA SHOULD STAY INFORMED ON THE LATEST
WEATHER CONDITIONS AND FORECASTS AND BE PREPARED FOR POSSIBLE ACTIVATION
THIS AFTERNOON AND TONIGHT.
