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
The weather through the end of next week is forecast to be typical
diurnal convection, with a focus on either coast, depending on the
overall wind flow for the day, which will enhance to sea lake
breeze which it is aligned with.

The 500mb pattern for the weekend, shows a trough over the deep
south. However, the trough axis may stay far enough north to have
little affect on south florida. There is a chance it could dig
slightly further south, which may help to enhance any convective
activity over the region this weekend.

Otherwise, a surface high to the east will meander around the
central atlantic and fluctuate in strength. For today and
Saturday, the high is forecast to bulge into the gulf of mexico,
bringing more of a southwesterly wind to the area. This would help
to enhance the gulf coast sea breeze. This would make the eastern
half of south florida more likely to see convection. Pwats,
between 1.75 and 2 inches today, are forecast to increase over the
weekend to 2 to 2.35 inches. This keeps plenty of moisture in the
area for convective activity. This would also bring the high
maximum temperatures to the interior and east coast today and
tomorrow. The heat index may reach to around 105 in portion of the
interior and in the eastern counties.

As for thunderstorms, general thunderstorms are currently
forecast. 500 mb temps should range between -6.5c and -7.5 most of
the week, with occasion slightly cooler air aloft. This would make
hail unlikely, and if it does occur, small at best. This leaves
heavy rain and wind. With a light steering flow for the week,
showers and storms may have very little motion to perhaps around
10 miles per hour. There may also be some backbuilding. Either
case may lead to some urban flooding concerns of roadways in poor
drainage and low laying areas.Also with the light flow,
waterspouts may also be possible over any of the south florida
waters for the next several days.

By Sunday, the surface high splits, with a weaker high center over
the northeast gulf and the atlantic high bringing more of a
southerly to southeasterly flow. This will allow for the atlantic
coast sea breeze to become more dominate, shifting the convective
activity back to the western interior and gulf coast. Even so,
models are indicating a high chance of convection for nearly all
of south florida Sunday and Monday.

The easterly flow is forecast to persist through the end of next
week. Aloft, models are indicating a ridge of high pressure will
slowly build over the eastern us. The models are in disagreement
with how strong the ridge will be, with the ECMWF having a very
strong ridge, and the GFS having more of a flat ridge. But, either
way, still showers and thunderstorms are in the forecast for the
remainder of next week as well, with the highest chances in the
interior and gulf coast next week.

Marine
An area of high pressure, with a westward extended axis, will
bring a southwest wind to the area today and tomorrow. By Sunday,
a weak high will develop over the northeast gulf, and the high
pressure center to the east will turn the wind southeasterly for
the remainder of the forecast period. Either way, showers and
thunderstorms, initiating daily over the mainland, may affect the
adjacent coastal waters as they move in the overall flow. Some
night time showers and storms are also possible in both the
atlantic and gulf waters of south florida. Seas are forecast to
run up to 2 feet, with occasional periods of 3 feet in the
atlantic waters. The wind may increase to 10 to 15 kts next week,
which would bring a moderate risk of rip currents to the atlantic
beaches.

Aviation
Isolated tsra in vicinity of kapf the last hour appears to be
weakening, though a few additional shra tsra in the area cannot
be ruled out the next couple of hours. OtherwiseVFR with light
winds rest of tonight. Scattered to numerous shra tsra should form
around 17 utc interior and east coast, with highest chances from
kpbi to kopf where prob30 is indicated and tempo restrictions may
need to be introduced in later updates. A period of ifr and
gusty erratic winds possible as tsra move near over terminals.
