What's New / NOTES
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

Synopsis..Light and somewhat variable flow will continue into midweek, increasing from the east-southeast late week as high pressure rebuilds to the north of the region. Both the gulf and atlantic sea breezes will enhance winds near the coasts each afternoon. Scattered Thunderstorms can be expected each day, especially over the open gulf and atlantic during the nights and mornings. Locally higher winds and seas can be expected near any storm that develops.
Gulf stream hazards..None the approximate location of the west wall of the gulf stream as of jun 27, 2017 at 1200 utc... 14 nautical miles east northeast of fowey rocks. 20 nautical miles east southeast of port everglades. 13 nautical miles east northeast of lake worth. 14 nautical miles east of jupiter inlet.

Update
Ir satellite imagery shows convection dwindling across the cwa
with cloud tops slowly warming. However, leftover boundaries from
this evenings storms may trigger a few showers and storms during
the next several hours. Another feature of interest is the line of
thunderstorms pushing northward off of the cuban coast. Short
term models show outflow from this activity possibly interacting
with boundaries near our coast early Wednesday morning. If this
occurs, additional thunderstorms may develop over the atlantic
waters. Will continue to monitor through the night. Previous
forecast package appeared on track, so besides loading in the
latest wind and sky guidance, did not have to teak other forecast
parameters.

aviation... Lingering convection this evening inland of terminals,
but will have to monitor outflow boundaries for additional isolated
development in the vicinity of both kapf and east coast terminals
through 02z. For now, best potential will be at kapf where vcsh
will start the forecast. Light calm winds overnight with dry
forecast expected. Tomorrow looks similar to today with vcts at
all sites beginning 14z-16z as seabreezes develop and move inland.

Tempo groups will likely be needed with later TAF packages as
timing of tsra can be better pinned down.

discussion...

latest water vapor imagery loop shows a cyclonic spinning low
over new york state with a longwave trough draped along the
the mid-atlantic. Surface analysis indicates a east- west
oriented stationary boundary sitting stagnant across north-
central florida. This feature has managed to push the bermuda high
eastward, away from our region, resulting in near natural flow.

Thus, well established sea breezes have already developed and
continue to push inland, towards the interior. Satellite derived
pwat values range from 1.7 inches in the southern peninsula to
near 2.0 inches further north. These values are slightly higher
than climo and more than sufficient for heavy, slow moving storms.

With a modified dcape of 1,400 j kg, wet microbursts producing
strong wind gusts are also a possibility. Short term model
guidance progs convection to propagating across the interior
through the early evening. After diurnal heating ceases, activity
should begin to wane. SPC has placed a marginal risk of severe
weather from west palm beach to lake okeechobee, so will continue
to monitor for the remainder of the day. Tomorrow should be a
similar set up, with not much changing synoptically. Light flow
will again lead to sea breeze convergence inland from the coasts.

As the day progresses, outflow boundaries will shift most of the
convection towards the interior. Maximum temperatures tomorrow
are forecast to hover in the upper 80s along the coasts, with
lower 90s inland. These values are around normal to slightly above
normal for this time of year.

Late next week into the weekend: by Thursday, both the GFS and
ecmwf prog the aforementioned front to wash out and retreat
northward. This will allow surface high near bermuda to once again
increase in strength. Stronger southeast flow will begin to
concentrate afternoon convection back towards the western
interior, as sea breeze collision shifts west. Friday into this
weekend, a more typical summertime regime reestablishes itself.

Long range models show an elongated high building aloft over the
peninsula with surface high building near bermuda. This pattern
typically brings persistent southeast flow. Afternoon convection
will most likely occur in the western interior and gulf coast with
night showers affecting the east coast metro region. Pwats
decrease slightly below climo during this time frame, so not
anticipating much in the way of significant heavy rain events.

Marine... Winds and seas should remain below small craft advisory
criteria across the local waters through the forecast period with
mainly light southeasterly flow prevailing. Sea breezes may
enhance winds near the coast to 10-15 knots at times each
afternoon. Only exception will be with any thunderstorm that
forms, which will bring brief periods of strong gusty winds and
rough seas. Waterspouts are also possible, especially in the
morning hours, mainly over the atlantic waters. Seas will be 3
feet or less heading into the weekend.

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.
