VFR conditions to prevail at all sites through the next 24 hours.
Current micron satellite shows a large low level cloud shield
extending south across the Florida Peninsula and eastern Gulf of
Mexico. Associated ceilings should stay just in the VFR range. Will
amend as necessary. Otherwise...westerly to northwesterly flow
will prevail through the morning at all sites as an area of low
pressure across the western Atlantic continues to retreat further
to the northeast.

Updated the coastal waters forecast...mainly for the winds across
the region. Regional observations indicate that generally west to
southwesterly winds in the 15 to 20 knot range continue across the
regional waters...including Biscayne Bay and Lake Okeechobee.
Earlier today there were concerns that seas could reach 7 feet in
the off shore Gulf waters tonight but recent marine guidance
indicates seas to 6 feet expected. A precautionary statement is
in effect for all local waters...including Biscayne Bay and Lake
Okeechobee. The latest guidance indicates winds are expected to
slowly subside tonight into Sunday while remaining generally
westerly to northwesterly.

Short term...(tonight-Monday night)...
The afternoon surface analysis showed the cold front responsible for
the active start today extending south-southwest from Cape Canaveral to Key West
and breezy west-northwest flow and drier conditions filling in behind it along
the Gulf Coast. Observations reflect this boundary and generally
show a west to east temperature/deep gradient across the area today from the
Gulf Coast to the Atlantic coast. The latest hrrr and WRF
reflectivities continue to show a few showers developing along the
front as it continues east this afternoon toward and through the
Atlantic coast...mainly north of Fort Lauderdale to the Palm Beach
coastal areas through the late afternoon hours. Otherwise...dry
conditions are expected through the remainder of the weekend and
into the upcoming week with temperatures remaining around normal.
The latest short-range model guidance reflects this dry pattern and
indicates the upper low centered north of the area lifting northeast
through this time as upper heights rise across the region. Another
cold front...dry...will move south and through the state on
Monday...which will reinforce the dry air and northerly flow over
Another cold front will be moving through South Florida by the
middle of next week from the north. However...the front will be a
dry cold front which will reinforce the dry and pleasant weather
over the area through the end of the period. Temperatures are
forecast to remain around normal through the week as the low-level
flow shifts to the southeast and upper heights rise.
Much drier conditions will be expected over the remainder of the
weekend as high pressure builds eastward over the region in the wake
of a cold front moving through the area today. A moderate northerly
swell will be expected to fill in across the Atlantic waters Monday.
This swell combined with moderate to fresh northerly winds will lead
to advisory level conditions for the Atlantic waters through this
time early next week.
