.DISCUSSION...Chances for afternoon showers and thunderstorms will
continue through the middle of next week before we see things
begin to dry out. Frequent lightning, moderate-to-heavy rain
capable of resulting in flash flooding and erratic gusty outflow
winds will be possible with any storms that develop. Temperatures
will return to normal on Monday, then dropping below normal
beginning on Tuesday. Outside of the potential for strong outflow
winds from showers and thunderstorms, no significant winds are
expected through the forecast period.
Note: Thunderstorms imply gusty and erratic winds.
