Marine Weather and Tides
Gulf Stream, FL

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.

Aviation
Another typical summertime pattern with diurnal convection is
forecast for south florida for Monday, with late morning to early
afternoon initialization of showers and thunderstorms, pushing to
the interior by the sea breezes. With an easterly component to the
general flow, the east coast sea breeze should be dominate,
allowing the best chances for late afternoon to evening tsra to
occur at kapf.VFR with brief ifr possible under +ra +tsra.

update...

showers with isolated storms continue over the gulf waters,
atlantic waters off palm beach, and some of the northern half of
south florida. Recent hrrr runs are going kind of crazy showing
plenty of rain over south florida overnight. Although the hrrr is
undoubtedly overdoing it... It did initialize fairly well, and the
atmosphere over south florida is quite moist. Other models also
show a few periods of isolated to scattered activity overnight.

Furthermore, the northern end of a westward moving caribbean tropical
wave is over cuba near our longitude and is helping to enhance
moisture over south florida, as viewed from cimss tpw imagery.

Given all of the aforementioned factors, I am forced to raise pops
slightly overnight for this update. Basically, after 11pm, we
have now have 20 pops for most inland and western areas for most
of the night with 30s for the east coast. Therefore, there is a
slightly higher chance of overnight showers over land tonight
compared with previous nights, and this is mainly due to enhanced
moisture from the tropical wave.

Prev discussion... Issued 359 pm edt Sun jun 24 2018
discussion... This afternoon through Tuesday night: a weak
surface ridge over the northeastern gulf will cause winds over
south florida to be east-southeast through Monday. This flow will
bring conditions that are quite moist. On Tuesday, the ridging
over the northeastern gulf weakens and moves north, leaving very
light to calm winds on Tuesday. We still expect conditions to be
quite moist on Tuesday as well. During this time, expect east
coast sea breeze to spark showers and storms in the eastern half
of the peninsula in the early afternoon, with the bulk of the
activity over the western half of the peninsula towards late
afternoon. Showers and storms will be favored over land during the
daytime hours, with scattered nocturnal storms over the atlantic
and gulf waters, although there is a higher chance of nighttime
activity over the atlantic than the gulf. Generally the storms the
next couple days should be typical summertime pulse storms. With
high freezing levels and warm conditions aloft, hail won't be a
concern. Brief gusty winds and some isolated street flooding are
possible with the heavier activity along with frequent lightning.

High temperatures the next couple of days will be near normal,
especially for the east coast, due to the moist conditions,
numerous showers and storms, and easterly flow. West coast may be
a little warmer than normal in the early afternoon before the
storms arrive.

Long term (Wednesday through next weekend): weak southeast flow will
continue as a weak ridge is nearly directly overhead or just to our
north. This will keep the same pattern of showers and storms moving
gradually from east to west through the day, with some nocturnal
activity possible over the water. Guidance indicates the
possibility of some dry saharan air moving near or over south
florida late in the week. If this materializes, then it would
decrease the rain chances over south florida. Therefore, i
decreased pops for the southern half of south florida by about 10
percent from the previous forecast package Wednesday night through
Friday. High temperatures are likely to be above normal for
western areas mid to lake week with heat index values possibly
over 105 in spots.

Marine...

southeasterly to easterly wind flow will continue through the
week. We will see scattered nighttime and isolated daytime
showers and thunderstorms over the south florida waters for the
next several days. Sea will be generally 2 feet or less. Locally
higher seas and gusty winds are possible with any gusty showers or
thunderstorms.
