accompany the stronger activity later this morning.  A flash flood
watch is in effect for most of eastern Oklahoma until 1 pm.

Some of the stronger activity this morning across eastern
Oklahoma may produce wind gusts around 50 mph and small hail.

Rain and thunderstorms are expected to diminish in areal coverage
this afternoon as the complex pushes off to the east. Low
thunderstorm chances will persist through the afternoon as
additional development will be possible along any residual

Sunday as another complex is expected to move into the area. Heavy
rainfall potential will increase with this complex as well. The
unsettled pattern will continue with ongoing thunderstorm chances
through mid week. As the pattern shifts some at that time... more
settled weather towards the end of the work week is likely...with
warmer temperatures.
