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.

Update
Showers and a few thunderstorms have been slow to wind down early
this evening. As of 815pm, some activity was located over broward,
eastern hendry, glades, and southwestern palm beach, with isolated
activity around miami-dade. I made some adjustments to pops for
the rest of the evening based on latest radar and short-term model
trends. Generally increased pops slightly for most of south fl
through the evening hours. Even though most of the activity will
wind down by late evening, can't rule out an isolated late night
shower or storm on land or over the waters as moisture
levels pwats are quite high over the region.

the winds will be light and variable tonight into Saturday morning
before going west northwest around 5 to 10 knots Saturday
afternoon. Vcsh will continue for all TAF sites through 02z this
evening before going dry tonight into Saturday morning. The east
coast TAF sites will see vcts for Saturday afternoon with vcsh for
kapf TAF site. The ceiling and vis will remain inVFR conditions
through Saturday, but could fall down into MVFR or even ifr
conditions with the passage of the showers and thunderstorms on
Saturday afternoon.

as expected, showers and storms formed today and have recently
been migrating eastward. Expect scattered to numerous storms
through the rest of this afternoon for the eastern counties, with
the greatest concentration likely palm beach county. A few showers
and storms could persist until an hour or two after sunset before
most of the activity diminishes this evening.

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.

The 500mb pattern for the weekend shows a trough over the
southeastern u.S. 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, the bermuda high well to our east will meander around the
central atlantic and fluctuate in strength. The west winds being
experienced over south florida today will persist into Saturday, as
the high continues to bulge into the gulf of mexico. This would help
to enhance the gulf coast sea breeze again on Saturday. This would
make the eastern half of south florida more likely to see
convection. Expect a similar pattern Saturday as today, expect rain
chances will be higher on Saturday because pwats will be higher.

Pwats of 1.75 to 2 inches today will increase over the weekend to 2
to 2.35 inches. This keeps plenty of moisture in the area for
convective activity. The west winds will also bring the higher
maximum temperatures to the interior and east coast again tomorrow
before the storms get going. The heat index may reach to around 105
in portions 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 occasionally slightly cooler air aloft. This would make hail
unlikely, and if it does occur, small at best. 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 this weekend into
early next week. 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. Moisture will remain quite prevalent over the area, and
pops will remain high, especially interior and west coast next
week.

Marine...

an area of high pressure, with a westward extended axis, will
bring a southwest wind to the area through 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 seas to 3 feet in the atlantic
waters. The wind may increase to 10 to 15 kts from the SE next
week. Therefore, look for an increasing risk of rip currents for
atlantic beaches early next week.
