EASTERN OKLAHOMA/NORTHWEST ARKANSAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
922 PM CST SUN MAR 11 2001

APPEARS TO BE A BREAK IN THE RAIN OVER MUCH OF THE AREA AT THIS
TIME.  EVEN SO...HIGH POPS IN CURRENT FORECAST SEEM WARRANTED AS A
LINE OF SHOWERS AND THUNDERSTORMS IS HEADED INTO CENTRAL OKLAHOMA.
COULD BE SOME STRONG STORMS ACROSS THE AREA BUT BELIEVE THE BEST
CHANCE FOR SEVERE STORMS WILL BE TO THE WEST AND SOUTH OF THE
FORECAST AREA.

TEMPS IN FORECAST AREA SHOULD NOT CHANGE MUCH TONIGHT GIVEN THE
CLOUDS...SOUTH WINDS AND DEW POINTS IN THE UPPER 40S TO MID 50S.
