.DISCUSSION...
Drier air is filtering in to lower overall thunderstorm coverage for
the first half of the week. However, low-level moisture will remain
sufficient to keep RH values well above critical thresholds. As
such, there are no significant fire weather concerns. Sea breezes will
turn winds to west-southwest in the afternoon each day.
