...Isolated thunderstorms expected this evening...

...Isolated to scattered thunderstorms expected Sunday afternoon and
evening...

.DISCUSSION...The main concern over the area will be
daily thunderstorm chances through at least mid-week. Through this
evening, expect isolated thunderstorms in the area. Gusty and erratic
winds are expected near any thunderstorms. These outflows may travel
away from the storm and affect surrounding areas. Additionally, small
hail and brief downpours are possible with any storms that develop
directly over the area.

Isolated to scattered thunderstorms are possible Sunday afternoon
and evening. These storms may bring gusty outflow winds, small hail
and brief downpours. Otherwise, expected continued warm
temperatures with breezy to gusty afternoon winds.  Winds may trend
slightly higher on Sunday afternoon.
