.Discussion...
A tropical wave continues to meander across the Florida Keys this
morning and will slowly exit to the west and northwest by the
afternoon and evening. This will maintain one more day of above
normal rain chances, before returning to near normal Monday.
Southeast winds this morning will decrease and back to the east
this afternoon, leading to poor dispersion. Min RH values will
hold above the 60th percentile and recover to near 90 percent
overnight.
