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
Widespread showers have enveloped south florida today, so tempo
groups in place through the evening. There may be a brief lull
tonight before more widespread showers move in after 8-12z
Saturday (handled with shra). Isolated thunderstorms are possible,
but aside from after daybreak Saturday in miami-dade terminals,
probability of lightning is too low to warrant mention in the
tafs. On and off cig restrictions are expected through this
evening associated with the heavier showers, but more widespread
sub-vfr CIGS are likely late tonight and through the day Sunday as
the atmosphere continues to near toward complete saturation. Ese
wind around 10 kt through sunset, then 5-10 kt overnight,
increasing to 15 kt or so by Saturday afternoon.

Update
Flood watch has been posted effective 12z Saturday through 0z
Monday. Widespread rainfall amounts of 4 to 8 inches, with locally
much higher amounts, are expected, and this may lead to flooding.

Additional information on this watch and subsequent forecast
updates will come later later this afternoon, but for now, see
miaffamfl for information.

Prev discussion issued 1121 am edt Fri may 25 2018
update 2...

the tropical storm probabilities on newly formed subtropical
storm alberto are 15 percent or less for all of south florida.

Therefore, no updates are required at this time to the forecast
for south florida.

Update 2... 54 bnb
prev discussion... Issued 1001 am edt Fri may 25 2018
update...

scattered showers have moved inland with sea breeze from the
atlantic. Expect coverage to increase through the day, especially
across the western interior, where locally heavy rainfall is most
likely. No significant changes in the forecast this morning.

Convective chances appear quite low based on 12z RAOB analysis.

The tropical disturbance east of the yucatan peninsula now has a
90 percent chance of tropical formation in the next 48 hours, and
this feature, the main player in our holiday weekend weather, will
continue to be closely monitored.

Prev discussion... Issued 347 am edt Fri may 25 2018
discussion...

primary forecast concern continues to be the probable development of
a tropical cyclone in the central or eastern gulf of mexico over the
next few days. The national hurricane center currently indicates a
70 percent chance of tropical cyclone formation within 48 hours
and a 90 percent chance of development within five days.

Some important differences remain among the numerical models and
ensembles regarding the eventual track and inner structure of the
cyclone, and how it interacts with a developing shortwave trough
over the western gulf, but there is general agreement in the
disturbance initially moving N or nne out of the yucatan channel
later tonight into the eastern or central gulf, before bending
northwestward as it moves into the northern or northeastern gulf
Sunday. The closest approach of the low to the SW fl gulf coast
will likely be Saturday night or Sunday morning.

A deep, long southerly fetch will set up over south florida
tonight into the weekend, between the developing cyclone over the
gulf and the ridge of high pressure over the western atlantic.

This plume will be characterized by anomalously high atmospheric
moisture content, with precipitable water values in the 2 to 2.4
inch range (90th-plus percentile of the climatological range for
late may). This will promote efficient warm rain processes and the
potential for excessive rainfall rates. Bands of heavy rain that
train over the same location will be a concern for significant
street flooding and may even threaten some structures in
vulnerable low-lying areas. Given the uncertainty in the location
and timing of the heaviest rain, it is still too early for a
flood watch to be issued, though one may be required in later
forecasts.

A low level jet of 35 to 45 kts is also likely to set up over s
fl late Saturday into Sunday. Forecast hodographs show a strong
anti-clockwise loop in the lower troposphere, with 0-1 km sreh
potentially exceeding 200 m2 s2 at times, along with sufficient
cape of 500-1000 j kg. Therefore, isolated tornadoes will be a
concern with any discrete convective elements during that time
period.

On Monday, the cyclone's forward motion slows or stalls over the
deep south, keeping S fl in the southerly plume, so high chances
for showers and thunderstorms will continue with ongoing
potential for locally heavy rain.

By mid-week, models begin to diverge on how quickly to kick out
or fill the surface cyclone, with some indication upper troughing
may continue into the gulf with a west atlantic high remaining in
place. This may continue the pattern of moist southerly flow and
elevated rain chances, but given the uncertainty, pops are trended
gradually toward climatology by later in the week.

Marine...

with the gulf low moving south to north just west of our gulf
waters, southeasterly winds over the local waters will increase
steadily tonight through Saturday over the local waters, peaking
out Saturday night into Sunday. There is the potential for
frequent gusts near or above tropical storm force in the offshore
gulf waters. Hazardous seas may peak near 10 feet by Saturday
night in the offshore gulf waters and near 7 feet in the atlantic
waters.

Beach forecast...

the risk of rip currents will increase at both the atlantic
and gulf beaches through the weekend.
