NATIONAL WEATHER SERVICE OKLAHOMA CITY OK
630 AM CST SUN MAR 24 1996

THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS FROM LATE MORNING
TO EARLY THIS EVENING ACROSS PORTIONS OF EAST CENTRAL AND SOUTHEAST
OKLAHOMA.

THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS THIS MORNING IN WESTERN

THUNDERSTORMS ARE EXPECTED TO DEVELOP THIS MORNING IN WESTERN PORTIONS
OF OKLAHOMA AND NORTH TEXAS ALONG AND AHEAD OF A DRYLINE. A COLD FRONT
MOVING INTO NORTHWEST OKLAHOMA TODAY WILL PROVIDE A SECOND FOCUS FOR
THUNDERSTORM DEVELOPMENT.

STRONG WINDS OF 50 TO 100 MPH AT MID AND UPPER LEVELS OF THE ATMOSPHERE
MOVING INTO THE SOUTHERN PLAINS WILL INCREASE THE THREAT OF HIGH WINDS
IN SOME THUNDERSTORMS.

LIMITING FACTORS FOR WIDESPREAD SEVERE WEATHER... ESPECIALLY THIS
MORNING... WILL BE MARGINAL INSTABILITIES. HOWEVER... DAYTIME HEATING...
COMBINED WITH COOLING TEMPERATURES ALOFT... WILL RESULT IN A MORE
UNSTABLE AIRMASS ACROSS EASTERN OKLAHOMA.
