.Discussion...
Enhanced moisture across the Keys will maintain near normal rain
and thunder chances through Saturday. That being said, the
isolated to scattered nature of these showers will mean that
rainfall amounts will be highly variable. Gentle to moderate
easterly breezes are expected through the next few days peaking in
the evenings and overnight and lulling during the afternoon. This
will keep daytime dispersion indices in the mid 50s over the next
couple of days. Min RH values will be in the mid 60s percent
today and Saturday with good RH recovery overnight to the upper
80s percent.
