What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Discussion
As has been the case the last several days, an initial round of
convection near the west suburbs of the east coast metro areas
and interior is gradually weakening and shifting west this
afternoon, and another flare up of convection is likely near the
gulf coast early this evening as the composite atlantic sea
breeze outflow boundaries from the earlier convection collide with
the gulf sea breeze hugging the coast.

Meanwhile, goes-16 precipitable water imagery indicates much
drier air lurking just northeast of the palm beaches which is
slowly sinking southwest as the ridge tries to strengthen build
into the region. With the ridge axis remaining just north,
generally light easterly flow will tend to focus any convection
over the interior and west. However with such dry air nosing
into the northeastern part of our area, pops the next couple of
days will be much lower over the palm beaches compared to the
southern interior, and coverage in general Tuesday-Wednesday may
be a bit lower than previous days.

Forecast soundings indicate warmer air aloft (-5c at 500), which
along with less moisture and tall skinny CAPE profiles indicate
low chances for any strong thunderstorms, though cannot rule out a
an isolated stronger thunderstorm where any boundary collisions
occur.

For Thursday and beyond, the weak ridge shifts south of the
region, bringing light generally west flow. This will allow
typical summer moisture to gradually re-establish and would tend
to focus diurnal convection over the interior and east coast, with
steadily increasing pops each day as moisture increases.

Marine
Generally good boating conditions with the high pressure ridge in
the vicinity, with seas generally around 2 feet or less and winds
generally 10 kts or less. Only exception would be near any
scattered showers and thunderstorms and associated outflow, where
winds and seas would locally briefly increase.

showers and thunderstorms are developing as the sea breezes
advance inland this afternoon. Some backbuilding storms over the
next hour or so could bring sub-vfr conditions to the east coast
terminal. Convection will likely peak by 21z over the interior and
diminish as the sea breezes retreat back towards the coast this
evening. Light wind expected overnight into the morning before the
pattern repeats on Tuesday. Slightly drier air could limit
convection on Tuesday compared to today.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
