Fire Weather Planning Forecast for the Florida Keys

.Discussion...
Rain chances will increase over the course of today and tomorrow
as an area of unsettled weather passes by just to the south of the
island chain. The heaviest showers should stay just offshore, but
we may be brushed by some isolated pockets of rainfall that may
lead to a few tenths of an inch. Conditions aren`t necessarily
favorable for lightning, but we can`t rule out the low possibility
of infrequent thunderstorms. An increase in moisture will be
reflected in the humidity values as minimums will be close to 80%
before increasing to near saturation overnight.
