Version 3.4
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
Showers and thunderstorms likely once again for south florida,
with the interior and southeast florida metro area having the best
chances for activity.

A strong ridge of high pressure remains well to the east, and a
secondary high is forecast to form of the southwest florida coast.

The models are indicating this will bring a northwest wind for a
good part of the day to the area. With this flow, any convection
will move to the southeast, giving the miami-dade and broward
metro areas the best chances for showers and thunderstorms early
on. The flow is likely to be disrupted by the sea breeze
development and convective outflow boundaries. This should allow
for the convective activity to migrate to the interior areas by
mid to late afternoon. However, convection still is likely across
all of south florida through the afternoon and early evening
hours.

As for how strong the convection will be, there may be several
factors. First, the 500 mb temp is forecast to be slightly on the
warm side, between -6.5c and -7c. The freezing level, on last
nights sounding was at 15.6k ft. This would make hail unlikely,
but not impossible, at least for small hail. Pwats are forecast to
remain well above 2 inches, indicating heavy rain with any
convective activity. Taking a look at the bufkit mbe vectors, the
storm motion should be slow, being under 10 kts. This may lead to
some urban street flooding for the east coast metro areas today.

Gfs and NAM model soundings showing ncape near .2, indicating some
decent vertical velocities. Together with possibly a small dry
layer aloft, could allow for some downbursts of 40 to 50 miles per
hour. However, this mornings sounding will give a better
indication of thunderstorm characteristics today.

For Sunday, the gulf high begins to migrate to the northwest,
lessening its influence over the wind pattern through the day.

This will allow for the atlantic high to bring the southeast flow
back to the area by the afternoon hours. The wind is then forecast
to be generally out of the southeast for the remainder of the
week. Moisture is forecast to remain over the area, and by Monday,
a 500mb ridge is progged to begin to build over the eastern us.

The GFS has come more in line with the ECMWF with strong ridging,
centered to the north. This should keep the 500mb temps on the
warm side, and allow the weather to be mainly sea breeze dominated
for the week. Showers and thunderstorms are forecast each day for
the afternoons across south florida. Basically, the typical
summertime pattern of diurnal showers and storms over the mainland
and some nocturnal activity over the coastal waters each night.

Marine
High pressure in the gulf today is forecast to bring a northwest
wind up to 10 kts across the area. As the high migrates away from
the area, a stronger high well to the east will regain influence
over the weather pattern. This will bring the wind back around to
the southeast for the remainder of the week. Showers and
thunderstorms will be possible through the week. Seas are forecast
to run up to around 2 feet, with locally rough seas under gusty
showers and thunderstorms. Also, with a light wind field in the
mornings, and then with any convection in the afternoon, along
with boundary collisions, waterspouts will continue to be
possible.

Aviation
Cannot rule out an isolated shra overnight, otherwiseVFR and
calm prevailing. Scattered shra and isolated tsra likely to
develop after 12 utc interior and east coast, increasing to
numerous shra tsra after 17 utc, with highest chances 19 to 22
utc. As was observed on Friday, any tsra moving over a terminal
would bring a period of ifr and gusty erratic winds. Expecting
less coverage but still some shra and isolated tsra near the gulf
coast. Conditions improve after sunset tonight.
