THUNDERSTORM OUTLOOK
NATIONAL WEATHER SERVICE OKLAHOMA CITY OK
630 AM CDT FRI JUN 09 1995

THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS OVER NEARLY ALL OF
OKLAHOMA AND WESTERN NORTH TEXAS.  THE PRIMARY THREATS WILL BE LARGE
HAIL...DAMAGING WINDS...AND TORNADOES.

THE ATMOSPHERE OVER THE SOUTHERN PLAINS STATES WILL BE VERY UNSTABLE
THROUGH TONIGHT.  IN ADDITION...LOW LEVEL MOISTURE WILL CONTINUE TO BE
FED INTO THE REGION AS SOUTH TO SOUTHEAST WINDS PERSIST ACROSS TEXAS AND
OKLAHOMA.  THESE CONDITIONS WILL FAVOR THE DEVELOPMENT OF STRONG
THUNDERSTORMS THROUGH THE DAY AND INTO TONIGHT.  THE LOCATION OF THE
DEVELOPMENT WILL BE DETERMINED MAINLY BY THE LOCATION OF SURFACE
BOUNDARIES.  AN OUTFLOW BOUNDARY...RESULTING FROM OVERNIGHT STORMS...
LAY ACROSS OKLAHOMA ABOUT 75 MILES NORTH OF THE RED RIVER AT 630 AM.
THIS BOUNDARY WILL MOVE SLOWLY NORTH DURING THE DAY AND WILL PROVIDE ONE
FOCUS FOR STORM DEVELOPMENT.  OUTFLOW FROM DEVELOPING STORMS IN THE
EASTERN TEXAS PANHANDLE AND NORTHWEST OKLAHOMA THIS MORNING WILL LIKELY
PRODUCE ANOTHER BOUNDARY WHERE STORMS WILL BE LIKELY TO DEVELOP.
THE WIND PROFILE...ESPECIALLY IN COMBINATION WITH STRONG INSTABILITY...
WILL FAVOR THE DEVELOPMENT OF SUPERCELLS AND A FEW TORNADOES.

BASED ON THESE FACTORS...IT APPEARS THAT CENTRAL OKLAHOMA WILL HAVE THE
GREATEST RISK OF SEVERE WEATHER TODAY AND TONIGHT.

HEAVY RAINFALL WILL BE LIKELY WITH MANY OF THE STORMS AND RENEWED
FLOODING WILL BE A PROBLEM IN SOME AREAS.

STORM SPOTTERS AND EMERGENCY MANAGERS SHOULD MONITOR THE LATEST
FORECASTS AND BE PREPARED FOR ACTIVATION TODAY AND TONIGHT.
