A bermuda high continues to control the weather pattern through
the TAF period. However, the easterly wind will be a bit stronger
today, which should push most of the convective activity inland,
and towards the gulf coast. Even so, some outflow boundaries may
push back towards the atlantic coast late this afternoon. Have
added some vcts for a few hours to cover this in the afternoon.

discussion...

latest water vapor imagery shows a large dome of high pressure
dominating the florida peninsula, with little in the way of
synoptic features to note. Surface high pressure continues to sit
stagnant, stretching from the eastern gulf of mexico to the
western atlantic. The mfl 00z mfl sounding displayed light
easterly winds from the surface to above 300 mb with pwat values
just shy of 1.70". As with the past several nights, short range
models indicate mostly dry conditions with a slight chance of
showers over the atlantic waters. Not much change is expected in
the synoptic pattern today, leading to a very similar setup as
yesterday. Light south easterly flow will allow both the atlantic
and gulf sea breezes to develop. These breezes should once again
trigger isolated scattered garden variety showers and
thunderstorms inland from the coasts, moving towards the interior
through the afternoon. Maximum temperatures will range from the
low to mid 90s across the region, a couple degrees warmer than
average for this time of year. On Friday, southeast flow will
continue with a pocket of drier air advecting in from the
southeast. GFS forecast pwat values drop to below 1.50" by the
late afternoon. Thus, expecting less thunderstorms coverage,
especially over the south and eastern portion of the cwa.

Saturday through early next week: on Saturday, both the GFS and
ecmwf agree in pushing an upper level low pressure system towards
south florida from the east. Pwats associated with this feature
are forecast to increase over 2.00" by Saturday afternoon. Deeper
moisture, along with various impulses of positive vorticity
advection, will bring more of a widespread rain threat to the east
coast metro region than previous days. Conditions stay favorable
for elevated shower and thunderstorm activity through Sunday,
before decreasing slightly on Monday. Long range models are
indicating yet another tropical wave to affect south florida late
Tuesday into mid next week, elevating the threat for heavier and
more widespread showers and thunderstorms.

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.
