DISCUSSION...
SHOWERS AND THUNDERSTORMS THAT DEVELOPED OVER CENTRAL OKLAHOMA
EARLIER THIS MORNING HAVE BEEN MAKING SLOW PROGRESS TO THE
EAST AND INTO THE WESTERN PORTIONS OF THE TSA CWA. THIS ACTIVITY
IS PARTIALLY THE RESULT OF ISENTROPIC LIFT ALONG THE 305K SURFACE
AND THAT IS EXPECTED TO WEAKEN OVER THE NEXT SEVERAL HOURS. WOULD
EXPECT THE SHOWERS AND THUNDERSTORMS TO PERSIST INTO THE EARLY
AFTERNOON BEFORE DIMINISHING.

HAVE AND WILL CONTINUE TO MAKE ADJUSTMENTS TO THE GRIDS TO BETTER
REFLECT LATEST TRENDS AND MODEL DATA. HAVE LOWERED MAX TEMPERATURES
FOR TODAY A FEW DEGREES AREA-WIDE DUE TO THE EXTENSIVE CLOUD COVER
AND CONVECTIVE ACTIVITY.
