.Discussion...
Light to gentle southerly breezes will persist today, promoting
poor to fair dispersion indices. A combination of light winds and
increasing low level moisture may allow for a weak cloudline to
develop across the Lower Keys this afternoon with a slight chance
for showers. Moisture and instability will be gradually
increasing ahead of the next approaching cold front tonight
through Monday. An isolated thunderstorm or two cannot be ruled
out at this time. Min RH values will hold above 70 percent and
recover into the mid to upper 90 percentile overnight.
