.DISCUSSION...
Moisture has increased across the region and will remain high
through the weekend. This will allow showers and thunderstorms
to fire each afternoon, favoring the southern half of the forecast
area today before increasing in coverage through the weekend. In fact,
this convection looks to continue through midweek. Fire weather concerns
will be low through the period.
...GUSTY ERRATIC WINDS CAN BE EXPECTED NEAR ANY SHOWERS
OR THUNDERSTORMS...
