Update
Another nice day in store as high pressure extending over the
eastern united states continues to provide a dry north wind flow
down the peninsula. Relative humidity values will drop below 35
percent over most of south florida today, with some moderation
along both the gulf and atlantic coasts this afternoon with the
inland push of the sea breezes. After a cool morning, temperatures
are on track to reach the upper 70s most areas, and near 80 over
areas of the everglades big cypress np.

A lingering, small northerly swell along with a rather high
amplitude in the tidal ranges will lead to an enhanced rip current
risk at the atlantic beaches today, especially palm beach county
where the swell is most noticeable.

vfr and dry conditions to prevail through forecast period as high
pressure dominates the local weather pattern. Offshore wind less
than 10 knots through 16z-17z, then sea breezes around 10 knots at
all terminals. E wind increases along the east coast after 00z...

around 10 knots with occasional higher gusts, with the onshore
wind bringing sct bkn cloud layer around 3,500 ft to these sites
near the end of the period. Kapf wind becomes light NE after 03z
with mainly clear skies there.

Dry, sunny Saturday across south florida
Discussion...

an area of high pressure has settled over the gulf of mexico to end
the week. The clockwise flow around the high will allow for a
northerly component to remain in the wind until the high pressure
builds northward from the gulf into the eastern third of the nation,
shifting the flow over southern florida out of the east by late
Saturday. This shift will allow for a warming and moistening trend
to take hold which will allow rain chances to return to the forecast
by early next week.

The next system will move into the eastern third of the united
states early on Monday, spurred on by a mid-level trough that will
amplify as it pushes eastward across the state on Tuesday but the
progress will end by Wednesday with the trough sitting somewhere
between the peninsula of florida and the bahamas. Things will get
moving again by Friday as the trough slides over the atlantic
with the potential of a cut off low forming. High pressure will
attempt to build in over the eastern seaboard behind the mid-level
trough and associated surface front, but the next frontal
boundary will quickly approach the middle third of the nation on
Thursday and progress south and east through the end of the week
to conclude the forecast period.

Temperatures will remain pretty close to seasonal averages for
this time of the year. This morning will probably be the last of
the chillier ones though the season norm does bring 30 or so
degree diurnal temperature swings each day thanks in part to the
drier air and the better Sun angles.

Marine...

easterly surges of wind through the weekend could produce cautionary
conditions over the waters with a chance of brief bouts of advisory
conditions in the gulfstream. The next period of hazardous seas will
arrive mid week behind a front with seas in the atlantic reaching 9
to 11 feet.

Beach forecast...

an elevated risk of rip currents will likely persist through a good
portion of the week. Increasing winds behind frontal passage will
allow seas to build which could lead to not only a high risk of
rip currents mid to late week but also the potential for beach
erosion and some coastal impacts. It is still early in the
forecast period but those with interests tied to coastal flooding
should monitor the forecast evolution through the weekend and
early next week in case the threat to the coast materializes and a
high surf advisory or coastal flood statement become necessary
for the atlantic.

Fire weather...

relative humidity values will dip into the 30s across a good portion
of southwest florida and portions of interior southeast florida this
afternoon. Energy release component values remain well below
critical thresholds while wind speeds should remain below 10 mph
across the driest areas today.

Prev discussion... Issued 135 am edt Sat mar 23 2019
aviation...

mainly skc prevails through the next 24 hours as strong high
pressure keeps subsidence in place across the region. Light and
variable flow will turn E around 10kt this afternoon. Only
exception will be apf where a sea breeze is expected to develop
around 18-19z.

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.
