OKLAHOMA THUNDERSTORM OUTLOOK
NATIONAL WEATHER SERVICE OKLAHOMA CITY OK
1 PM CDT SAT APR 18 1992

THIS OUTLOOK APPLIES ONLY TO OKLAHOMA ZONES 4 THROUGH 21.

THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS ALL OF
CENTRAL AND WESTERN OKLAHOMA THIS EVENING AND TONIGHT WEST OF A
PONCA CITY TO WETUMKA TO MADILL LINE.

A STORM SYSTEM ACROSS NORTH TEXAS IS SPREADING WIDESPREAD CLOUDINESS
AS WELL AS SHOWER AND THUNDERSTORM ACTIVITY IN THAT AREA. THE LATEST
COMPUTER FORECASTS INDICATE THAT THIS SYSTEM WILL TAKE AWAY MUCH OF
THE MOIST UNSTABLE AIR WHICH WAS EXPECTED TO FEED A SECOND STORM
SYSTEM APPROACHING FROM THE WEST TODAY. THIS FIRST UPPER STORM SYSTEM
WILL MOVE NORTH INTO EASTERN OKLAHOMA DURING THE AFTERNOON AND CONTINUE
THE CLOUDS AND SCATTERED THUNDERSTORMS TO CENTRAL AND EASTERN OKLAHOMA.
A DRYLINE IS CURRENTLY LOCATED ACROSS THE EASTERN OKLAHOMA PANHANDLE AND
THE TEXAS PANHANDLE.

ACROSS NORTHWEST OKLAHOMA AND PORTIONS OF THE TEXAS PANHANDLE THE SKIES
HAVE CLEARED...ALLOWING THE TEMPERATURES TO RISE AND THE AIR TO BECOME
MORE UNSTABLE...BUT EVEN HERE THE AIR IS MARGINALLY UNSTABLE. SOME
STORMS MAY FIRE ALONG THE DRYLINE THIS AFTERNOON BUT MAY NOT BECOME
SEVERE UNTIL COOLER AIR IN THE UPPER LEVELS MAKES THE AIR CONSIDERABLY
MORE UNSTABLE LATER THIS EVENING. THESE STORMS ARE THEN EXPECTED TO
MOVE INTO THE EASTERN PART OF THE THREAT AREA OVERNIGHT.

OF GREATER CONCERN IS THE POSSIBILITY OF A SIGNIFICANT OUTBREAK OF
STORMS EASTER SUNDAY...INCLUDING SUPERCELLS WITH TORNADOES... ACROSS THE
EASTERN PORTION OF THE FORECAST AREA...FROM A BLACKWELL TO ARDMORE LINE
EASTWARD. THE CONDITIONS SHOULD BE CONSIDERABLY MORE FAVORABLE FOR
SEVERE STORM DEVELOPMENT WITH MUCH GREATER INSTABILTY
THROUGH THE ATMOSPHERE..AN ADVANCING SURFACE FRONT...AND A POWERFUL
UPPER LEVEL STORM SYSTEM. THE NATIONAL WEATHER SERVICE WILL
CONTINUE TO PROVIDE UPDATES ON THE SEVERE WEATHER POTENTIAL AS
MORE INFORMATION IS AVAILABLE. LISTEN TO RADIO AND TELEVISION... OR NOAA
WEATHER RADIO... FOR UPDATES.

EMERGENCY MANAGEMENT OFFICIALS ACROSS CENTRAL AND WESTERN OKLAHOMA
SHOULD KEEP UP WITH THE LATEST FORECASTS AND BE PREPARED FOR POMSSIBLE
ACTIVATION LATER THIS EVENING AND TONIGHT...AND EMERGENCY MANAGEMENT
OFFICIALS IN THE REMANINDER OF THE FORECAST AREA SHOULD BE ALERT
FOR THE POSSIBILITY OF SEVERE WEATHER SUNDAY.
