1020 am edt Fri jul 28 2017

Update
As of 1020 am edt... A more active convective day is expected
across south florida as a weakening ridge allows winds to veer
more southerly. With a more southerly wind flow in place, the east
coast sea breeze will have a difficult time making any decent
inland push, while the gulf sea breeze will be able to go inland
further than usual. Scattered showers and thunderstorms will be
possible, especially later this morning into the afternoon, with
coverage becoming more numerous towards the late afternoon as
activity drifts and becomes focused over portions of the east
coast metro.

Poor drainage flooding in east coast urban areas will be of
concern later today, as storms will be slow to move with fairly
light steering flow. Frequent lightning and brief gusty winds of
30-40 mph will also be of concern with the strongest storms.

Outside of the storm potential for today, it will be hot yet again
with high temperatures well into the 90s. Heat indices will
generally be as hot as 105 degrees in most areas, with a few areas
briefly flirting with higher values at times. Will continue to
monitor potential for a short-fused heat advisory, but expected
convective development should hinder any more extreme heat
concerns for today.

generallyVFR flying conditions will prevail at the TAF sites,
with MVFR and possibly ifr restrictions in and around
thunderstorms. With flow becoming more south southwest, east coast
sites should see a better opportunity for activity later this
morning and through the afternoon, with vcts possible. Will
continue to assess trends in model guidance and may include tempo
groups to account for better timing in future amendments. East
coast sea breeze will have a hard time pushing inland today, but
still expect southeast winds generally around 10 knots, except
southwesterly at kapf.

discussion...

today: upper trough over southern ga and northern fl will move into
western atlantic waters today before it gets pick up by a deepening
trough along the northeast plains the coming week. This has allowed
for the ridge to erode with a more S to SW flow setting up over the
fl peninsula. There is still the potential for afternoon
scattered showers and storms mainly in the interior and building
into the east coast metro areas as the steering flow shifts more
southwest today. This will also limit east coast sea breeze from
developing this pm. High temperatures will remain above normal
ranging from the low to mid 90s across the forecast area.

Dewpoints will lower into the mid to low 70s today helping keep
heat indices ranging from the 100-108. Conditions will remain
below advisory criteria at this time for all south fl.

This weekend and next week: southwesterly flow will prevail through
the weekend as upper level low over the northeast plains deepens an
elongated trough along the east coast. This trough is expected to
remain in place through next week, potentially digging as far south
to fl bringing an unseasonably robust surface front into the state
Monday, potentially reaching as far south as central fl. Abundant
deep moisture ahead of the front will result in an increase period
of precipitation through mid week across south fl, with a few
more stronger storms possible as temps aloft cool down. Western
atlantic ridge gradually retrogrades westward returning SE flow
across south fl and as a result lifting the moist boundary north.

There will be a chance of showers and thunderstorm through the end
of the week but with less coverage into Friday.

A thick plume of saharan dust is observed tracking east over the
atlantic. This time it looks more robust stretching across the
atlantic into the greater antilles and eventually into florida by
the end of the week into next weekend. Models continue to show a
decent bulk of it north enough for most of the fl peninsula to feel
the effects of it.

Marine... Southeasterly winds will veer south to southwest today into
the weekend around 10 knots and begin to pick up up to 15 knots over
the 15 knots into Sunday. Expect the gulf seabreeze to develop today,
with the atlantic breeze struggling to develop as winds shift more
sw. Afternoon showers and storms will generally remain over the
interior, with more isolated activity over the open waters during
the nights and morning. Coverage of showers and storms are expected
to increase as we head into the weekend and early next week. Ridge
begins to build by the end of the week returning light southeast
flow across the coastal waters.

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.
