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.

Update
For this update, made minor adjustments to pops based on the
latest radar trends and short term model guidance. The east coast
sea breeze finally made it to the interior western half of south
florida. When the boundary hit the already forming showers and
thunderstorms, additional thunderstorms formed around 7pm.

Scattered thunderstorms are occurring in a broken nw-se line from
east of ft. Myers to east-central collier county to southwestern
miami-dade as of 8pm. Latest short term model guidance suggests
this activity is likely to persist into the evening hours in the
same general area. Most of the activity should begin to wane after
10pm and wind down by midnight. No other changes to the forecast
for this update.

update...

the winds will remain light and variable for tonight along with
vfr conditions in the ceiling and vis for all of the TAF sites.

The winds will then become southwest over most of the TAF sites on
Thursday, except for kpbi and kfll where they could go to
southeast direction after 19z due to the east coast sea breeze.

The weather will remain dry at kapf TAF site on Thursday, while
the east coast TAF sites will see vcsh from 14z till 19z, then
vcts from 19z till 00z. The ceiling and vis will beVFR conditions
outside of any showers or storms, but could fall into ifr
conditions in the showers and storms.

very little in the way of shower or thunderstorm activity
developed so far today as of 330pm with the exception of isolated
activity over the far southern interior. East coast sea breeze
clearly evident on satellite imagery penetrated inland to the
western suburbs of the east coast metro areas but the cumulus
hasn't built up enough to produce showers and storms. Still a
chance for isolated activity along the sea breeze before the
afternoon is over.

A mid-upper level ridge will gradually weaken but will remain in
place just to our north through Thursday. The placement of the ridge
will be such that mid to upper level moisture will gradually
increase over south florida by Thursday afternoon and into Friday.

Expect drier than normal conditions and only isolated shower and
thunderstorm activity through Thursday morning. On Thursday, the
low and mid level flow will become more westerly, but not early
enough or strong enough to prevent an east coast sea breeze.

Expect both sea-breezes to develop again and collide.

Shower thunderstorm chances will be a little higher on Thursday as
compared to Wednesday across the interior once the sea breezes
collide. The storms should migrate toward east coast metro regions
later in the afternoon due to the westerly storm motion. With the
westerly flow, temperatures will continue to be quite warm with
highs in the low 90s (maybe even the mid 90s for some spots) and
heat index values over 100 for many areas.

As the end of the week and the weekend approaches, there will be a
weak mid to upper level ridge over the region. This will allow for a
light west to southwesterly flow to continue. Scattered showers and
thunderstorms will develop each day along the sea breezes with the
greatest coverage of storms remaining over the interior during the
afternoon hours. By the end of the weekend into early next week,
both of the GFS and the ECMWF continue to show another ridge of high
pressure building in from the western atlantic. Based on the
orientation of this ridge in the pressure pattern, this should
cause low-level winds to be from the east or southeast Sunday into
Tuesday. This flow will increase the amount of moisture in the
area as well. As a result, showers and thunderstorms appear to be
likely during this time frame.

Temperatures will continue to show an upward trend Friday and
Saturday, with some mid 90s possible into parts of the southeast
florida metro area and near 90 to lower 90s elsewhere. Heat index
values may approach or even exceed 105f over parts of the area
Friday and Saturday, something to keep an eye on over the coming
days.

winds will remain near 10 knots or less through Thursday morning
for all waters. The winds will increase to slightly above 10 knots
and shift to a more west southwesterly direction across the
atlantic waters. Over the gulf waters, winds will remain out of
the west southwest at 10 knots or less. Scattered showers and
thunderstorms are possible each day. Winds and seas will be
locally higher in and around any shower or thunderstorm.

For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
