Discussion
Kbyx doppler radar loops show that convection flared close to and
along sections of the keys island chain today. Most recent images
show the activity is favoring the gulf side of the lower keys and
the atlantic side of the middle and upper keys extending well into
the straits. Under mostly cloudy skies and away from any rainfall,
temperatures are in the upper 80s with variable winds less than 10
knots.

The local surface pattern will remain quite weak over the next
few days while a distinct mid to upper level trough near the
western edge of florida eases westward. We will remain quite
moist and unstable as the low level flow acquires a light south
southeasterly component tonight through late Wednesday. The
overall forecast reasoning has not changed significantly from our
past few cycles, save for one distinction. That would be a low
amplitude, low level wave trough that eases across south florida
and the keys late this week into the early portion of the weekend.

On account of that feature, did bump our probability of measurable
precipitation up to likely from late the work week into early this
weekend. All other sensible weather grids were left relatively
unchanged for the other times of this forecast.

Marine
Away from scattered showers and at least a few thunderstorms, the
flow will remain light across the coastal waters surrounding the
florida keys over the next couple of days. No advisories or
cautionary headlines for small craft will be necessary.

Aviation
Tsra could affect eyw this afternoon and shra to mth, causing MVFR
or ifr vis and or cigs. Otherwise, winds will be variable at 5 to 10
knots this evening and overnight hours.

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.
