.DISCUSSION...
Showers and thunderstorms are ongoing again this afternoon while
moisture remains in the region. Concerns include localized flash
flooding, gusty outflow winds, hail, and lightning. A final push
of moisture moves through tomorrow, bringing widespread
precipitation. This weekend moisture will decrease, leading to a
return of drier conditions. However, below threshold wind gusts
should allow for only localized critical fire weather conditions.
...GUSTY ERRATIC WINDS CAN BE EXPECTED NEAR ANY SHOWERS
OR THUNDERSTORMS...
