Discussion
Current-tonight... Kxmr 08z morning sounding shows a pwat of 1.18
inches with continued dry air aloft above 800 mb. Fairly warm
temperatures aloft continue between 700/500 mb. 915 mhz CAPE wind
profilers continue to show fairly deep southeasterly flow across the
area. Surface high pressure remains stationed over the western atlc
with east-west oriented ridge axis just north of the fl peninsula.

The GFS continues to suggest pwat values increasing to 1.40-1.50
inches thru the day with highest values over the central interior.

Kmlb WSR-88D has been showing isolated sprinkles/light showers over
the coastal waters and occasionally across ecfl coastal counties,
but any QPF will remain light. The question remains if enough
parameters are in place for isolated activity to move into the
interior later today. Suspect there will be some spotty light pcpn,
but coverage probably well below 20 percent. The late day/early
evening sea breeze boundary collision looks like it could initiate
just west of lake county. With the uptick in moisture there will
definitely be more clouds around than we have seen recently,
including higher cirrus clouds.

Max temps in the m-u80s over the coastal counties and around 90f
inland under a breezy SE flow, especially near the coast. Overnight
mins should be similar to tonight, l70s inland and m-u70s along the
coast.

Aviation ContinueVFR outside of CU streamers producing
isolated/brief MVFR CIGS and vsbys in passing showers. Gusty se
winds again today slowly diminishing in the evening, but remaining
elevated along the space/treasure coasts again overnight. MOS again
hinting at some spotty MVFR CIGS late overnight into early mon
morning.

Marine Today-tonight... Marginal SCA continues for offshore legs
south of volusia-brevard county line, as well as near shore south of
sebastian inlet for gusty SE winds near 20 kts and seas up to around
6 ft. Cautionary statements generally elsewhere, except near shore
volusia coast where winds are around 15 kts and seas 3-5 ft.

Fire weather Previous... Min rh values expected to remain above
40 percent as low level moisture continues to creep upward. Gusty se
surface and transport winds will produce high dispersion and promote
rapid spread of any new fires and possible flareups of
existing/smoldering burns or hot spots.

Mlb watches/warnings/advisories
Fl... None.

Am... Small craft advisory until 8 pm edt Sunday for sebastian inlet
to jupiter inlet 0-20 nm-sebastian inlet to jupiter inlet 20-60
nm-volusia-brevard county line to sebastian inlet 20-60 nm.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
