Aviation
Isolated passing showers will continue today mainly along east
coast sites but not enough coverage to warrant vcsh any longer.

But did place a tempo group for the early morning hours and will
amend beyond that as needed. Another round of breezy conditions is
expected today, mainly after 15z, with gusts to around 25 kt.VFR
should prevail today, but periods of MVFR (mainly cigs) are still
possible in association with any shower across the sites.

Prev discussion issued 812 pm edt Sat oct 21 2017
update...

surface high pressure over the mid atlantic will continue to
generate moderate to strong easterly flow over south florida
tonight. Expect winds sustained generally between 10 to 15 mph
along the east coast metro region, increasing again by mid Sunday
morning. Latest NWS radar loop indicates light to occasional
moderate showers advecting onshore from the atlantic. Instability
parameters still appear rather weak, so have not included any
mention of thunder in the update. Short term models, such as the
hrrr and WRF show isolated showers persisting through the night,
so have adjusted pops accordingly.

discussion...

latest wpc surface analysis shows a strong 1029 mb
cell of high pressure over the mid atlantic region, with a weak
stationary boundary draped across the bahamas. The combination of
these two feature has tightened the surface pressure gradient across
south floria and increased easterly winds today. On average, winds
along the atlantic coast have been sustained 20 to 30 mph, slightly
weaker inland. Satellite derived pwat values are from 1.6"-1.7",
with a majority of the moisture located in the lower and upper
levels of the atmosphere. Weak instability has allowed for quick,
westward moving, light to moderate showers over the peninsula.

Not expecting any lightning with this activity, so have removed
mention from the latest forecast package. With little changing
synoptically tonight, expect gusty easterly winds to continue
along the east coast metro region, generally around 15 mph.

Sunday through mid next week: models begin to slowly shift the
aforementioned surface high eastward towards the mid atlantic
ocean. In response, flow will turn east southeasterly, then
eventually south southeasterly. Winds will remain breezy through
the period, especially along the east coast beaches and metro
regions. Mid range models prog a low pressure trough to deepen
over the ohio valley, dragging a sharp cold front southward over the
gulf. As this system begins to approach florida late Monday,
moisture will begin to pool ahead of the front. The GFS forecast
pwats increase to around 2.00" over our region. Intability
associated with the approaching front will also increase. Thus,
expect elevated chances for showers and thunderstorms Tuesday into
early Wednesday across the entire cwa.

Late into Friday: behind the frontal passage, much drier and
cooler conditions will ensue. Maximum temperatures are forecast
only in the lower 80s on Wednesday, then struggle to reach 80
degrees on Thursday. Dry weather is expected, along with dewpoints
plummeting into the 40s and 50s. This front is a sure sign that
the end of the rainy season is near.

Marine...

pressure gradient between a decaying front over the region and
high pressure over the southeastern united states will bring east
wind of 20 to 25 knots and seas of 5 to 7 feet for much of the
waters through the weekend. A small craft advisory remains in
effect over the atlantic waters and outer gulf waters through
early Sunday morning.

Aviation...

scattered showers streaming westward across much of south florida
should continue overnight. Activity has approached naples more
than anticipated so added vcsh for kapf from 20-0z. Easterly wind
gusts are likely to exceed 25 kt through sunset, then diminish
slightly overnight, before increasing again by mid-morning Sunday.

Shower chances drop off after daybreak Sunday, so for now have
left dry tafs for fll and miami-dade terminals.VFR should prevail
but periods of MVFR (mainly cigs) quite possible, especially
through the afternoon.

Beach forecast...

persistent easterly flow will allow the high risk of rip currents
to persist through the weekend into early parts of the work week.

The flooding along the east coast during high tide should begin to
decrease over the next several cycles as the new moon phase ends.

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.
