.Discussion...
A high pressure centered near Bermuda will pump in moisture across
the Florida Keys today. This will lead to above normal rain
chances. Chances for wetting rain will be highly dependent on
where showers pass over. Rain chances will remain elevated through
at least Monday. In addition, expect breezy conditions to develop
this evening and continue through Monday evening. Afternoon min RH
values will fall into the 60s and recover into the mid 80s to
lower 90 percentile.
