OKLAHOMA THUNDERSTORM OUTLOOK
NATIONAL WEATHER SERVICE OKLAHOMA CITY OK
300 PM CDT THU MAY 8 1986

A TORNADO WATCH IS IN EFFECT UNTIL 10 PM FOR MUCH OF WESTERN AND
CENTRAL OKLAHOMA. OTHERWISE THERE IS A MODERATE RISK OF SEVERE
THUNDERSTORMS THIS AFTERNOON AND TONIGHT OVER MOST OF WESTERN AND
CENTRAL OKLAHOMA. THE RISK AREA IS WEST OF A LINE FROM BARTLESVILLE
TO ARDMORE.. BUT EXCLUDES THE OKLAHOMA PANHANDLE. A SLIGHT RISK OF
SEVERE THUNDERSTORMS EXISTS LATE THIS AFTERNOON AND TONIGHT OVER THE
REST OF EASTERN OKLAHOMA.

A LINE OF STRONG THUNDERSTORMS HAS MOVED INTO EXTREME WESTERN OKLAHOMA
THIS AFTERNOON, WITH OTHER THUNDERSTORMS DEVELOPING OVER THE NORTHWEST
PART OF THE STATE. THE GREATEST NEAR-TERM CONCERN IS WITH THE LINE OF
STORMS NEAR THE WESTERN BORDER. SPOTTER NETWORKS IN WESTERN OKLAHOMA
SHOULD BE ACTIVATED OR ON STANDBY AT THIS TIME.

THE LINE OF THUNDERSTORMS IS ASSOCIATED WITH A DRY LINE MOVING SLOWLY
EASTWARD THROUGH THE EASTERN TEXAS PANHANDLE. AHEAD OF THE FRONT, THE
AIR REMAINS VERY MOIST AND VERY UNSTABLE OVER OKLAHOMA. ALOFT, A LARGE
UPPER LOW CENTER LIES OVER THE CENTRAL ROCKIES. WINDS ALOFT MOVING
AROUND THIS LOW HAVE BACKED TO A MORE SOUTHERLY DIRECTION OVER WESTERN
OKLAHOMA, WHILE REMAINING SOUTHWESTERLY OVER EASTERN PARTS OF THE STATE.
THIS PATTERN OF DIVERGING WINDS ALOFT IS FAVORABLE FOR ENHANCING THE
LIFTING OF THE AIR NEEDED TO TRIGGER AND MAINTAIN STRONG THUNDERSTORMS.

A DISTURBANCE IN THE UPPER FLOW IS MOVING NORTHEASTWARD FROM NEW
MEXICO, AND WILL SERVE TO FURTHER ENHANCE THE LIFTING PROCESS OVER
WESTERN OKLAHOMA THROUGH THIS EVENING. THIS DISTURBANCE WL ALSO ASSIST
IN PUSHING THE DRY LINE SLOWLY EASTWARD, WITH SEVERE WEATHER MOVING
EASTWARD INTO CENTRAL OKLAHOMA LATER THIS EVENING. SEVERE WEATHER COULD
CONTINUE INTO TONIGHT AND SPREAD INTO EASTERN OKLAHOMA, BUT THE SEVERE
POTENTIAL WILL DECREASE WITH THE LOSS OF AFTERNOON HEATING.

SPOTTER NETWORKS IN CENTRAL OKLAHOMA WILL LIKELY BE NEEDED BY EARLY
EVENING, WHILE THOSE IN EASTERN OKLAHOMA MAY BE NEEDED LATER TONIGHT.
ALL INTERESTS ARE ADVISED TO KEEP IN TOUCH WITH THE LATEST WEATHER
INFORMATION AND LISTEN FOR LATER STATEMENTS AND POSSIBLE WARNINGS.
