Florida visible satellite imagery shows that low level SE winds are occurring across the state as surface high pressure moves further east over the western Atlantic.  Note the SE-NW oriented convergent cumulus cloud lines eminating from the Bahamas Islands, and moving onshore across SE Florida.  These lines are indicative of increasing SE flow.  The increase in cloud cover over and south of the Florida Keys is evidence of increasing moisture heading northward.  This increased moisture will continue northward giving way to higher rain chances on Friday.
