Aviation
With convection waning this evening, and indications most sites
will be dry overnight, took out nocturnal shra at most sites,
although a few coastal shra will be possible, so kfll, and even
kpbi may have some shra. Tomorrow looks to bring more shra in the
morning, then tsra in the afternoon once again. Have vcts for now,
but will as timing is narrowed in models, tempo groups will
likely be added. This is ahead of a weak cold front which should
move through and quiet things down tomorrow night.

update...

lowered pops along the east coast metro areas for the overnight
hours based on radar trends and short term model output. Scattered
showers and thunderstorms will once again redevelop across the
region on Tuesday. The best chance for showers and thunderstorms
will be across the interior and east coast metro areas. The main
threats for these storms will be heavy downpours and frequent
lightning.

Prev discussion... Issued 349 pm edt Mon apr 23 2018
discussion...

sea breezes have developed this afternoon with scattered showers
and thunderstorms affecting mainly the eastern half of south
florida. There remains enough instability in place to still
support a strong thunderstorm or two across the region. The main
threats with these storms are frequent lightning, heavy downpours,
and wind gusts up to 60 mph. As the evening progresses,
stabilization in the wake of the convection from this afternoon
should allow for shower coverage to decrease just a little bit
overnight, however there will still be likely pops over the east
coast metro areas and the atlantic coastal waters.

On Tuesday, the latest computer model guidance shows the front
getting closer to south florida and the winds continuing to veer
around to the southwest. The west coast sea breeze will move
across the peninsula and collide with the east coast sea breeze
near the east coast metro areas during the afternoon. This will
allow for another round of showers and thunderstorms to develop
especially in the northeastern portion of south florida. A few
strong thunderstorms are once again possible with the main threat
being heavy downpours and frequent lightning. The cold front will
move through on Tuesday night and shower and thunderstorm activity
will decrease as the night progresses.

Behind the front, drier and more stable air will move into the
region on Wednesday and for the rest of the work week. A couple of
shortwave troughs will move through by the weekend and could
increase the chance of shower activity during that time, but that
will be something that needs to be watched as the models are still
in disagreement in regards to the timing of these features.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. 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.
