915 pm edt Sat mar 25 2017

Radar data still show areas of scattered showers moving across the
metro areas of northern miami-dade and broward counties, mostly
light rain. Shower activity will gradually subside tonight,
although any shower that develops over the atlantic coastal waters
could potentially move towards the metro areas through the rest of
this evening. Will keep mention of scattered showers for tonight's
forecast, mainly eastern areas. Winds are also gradually
decreasing with the gusty periods ending overnight.

The rest of the forecast package remains on track and no further
adjustments are required for the evening update.

Prev discussion /issued 812 pm edt Sat mar 25 2017/

easterly winds becoming moderate tonight will continue through
Sunday. MainlyVFR should prevail, except for brief periods of
MVFR CIGS and vis over fll, fxe and mia under passing showers
through 03z tonight. A drier day is expected on Sunday.

Prev discussion... /issued 500 pm edt Sat mar 25 2017/

marine conditions continue to slowly improve across the local
waters, and the small craft advisory for the atlantic waters is
no longer in effect. However, winds in the 15 to 20 kt range will
require keeping small craft exercise caution headlines into
tonight for the atlantic waters. Winds and seas will continue to
subside into early next week as high pressure and drier weather

near term /through 6 am Sunday morning/...

as of 300 pm edt... Latest surface analysis reveals a tranquil
weather pattern across south florida, with high pressure building
in from the north and weak upper-level ridging aloft. This weather
pattern has allowed for drier air from the north to continue to
slowly filter in across the region, with pwats now below 1 inch
helping to limit shower activity as compared to recent days.

Still, isolated light showers streaming in off the atlantic will
be possible the rest of today and into tonight, although most
areas will be dry.

The easterly flow will continue to gradually weaken as the day
progresses, allowing the gulf sea breeze to possibly develop late
this afternoon. It will remain breezy at times, with gusts of 20-25
mph common across the east coast. High temperatures look to top out
around 80 along the east coast, and low and mid 80s for the interior
and gulf coast. Low temperatures tonight will range from the upper
50s/lower 60s in the interior and gulf coast, to mid/upper 60s for
the east coast.

Short term /6 am Sunday morning through Monday night/...

the breezy easterly flow regime will finally begin to weaken in the
short term period, as drier air continues to filter in from the
north as high pressure at the surface ridges in from the north,
along with weak upper-level ridging aloft. South florida will
continue to remain disconnected from any major synoptic features
allowing for fair and generally dry weather outside of a few light
showers possible off the atlantic for eastern areas.

Highs Sunday and Monday will generally be in the 80s with lows
Sunday night generally in the 60s, with a few isolated upper 50s
readings in portions of the interior. Lows Monday night will range
from the mid 50s to mid 60s.

Long term /Tuesday through Friday/...

the long term period will feature generally tranquil and dry weather
as high pressure dominates. A dry frontal passage looks possible in
the midweek period, with little changes in sensible weather expected
in its wake. Long term model guidance is now hinting at the
potential for a more potent front impacting the region late in the
work week to weekend, and trends will need to continue to be
monitored as this front may be the next chance for widespread
rainfall and/or thunderstorms across the region.

With the east/southeasterly flow in place, temperatures will be
above normal for the long term period, with daytime highs well into
the 80s and lows in the 60s. In fact, high temperatures during the
midweek period may even make a run at the 90 degree mark across
portions of the interior.

Beach forecast...

a high risk of rip currents will continue for the atlantic beaches
through Sunday with strong easterly onshore flow. The rip current
risk for the atlantic beaches should begin to decrease by early next
week as the flow weakens and becomes more southeasterly.


isolated showers possible mainly miami-dade and broward terminals
through the period, but expected coverage, confidence in timing,
and likely minimal impact preclude mentioning in 18z tafs.VFR
conditions should dominate with 3-6kft CIGS at times over eastern
areas. E wind 15-20 kt with higher gusts through early evening,
before diminishing to 5-10 kt overnight. Winds will increase to 10
to 15 kt by mid-morning Sunday. Still looks like partial gulf
breeze will impact naples before about 20z, so have placed a few
hour period with southerly winds for kapf.

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.
