Discussion
Mean-layer ridging centered east of florida maintains a weak
surface ridge axis which stretches west to south florida. Light
breezes prevail across the coastal waters of the florida keys.

Temperatures are near 90 for most locations with dewpoints in
the mid 70s. The island chain has been rain free.

Forecast
Lower heights across the southeastern united states will pivot
northeast tonight, allowing the mean-layer ridge to rebuild to the
west on Wednesday. Meanwhile, high pressure currently centered
near the mississippi river valley will progress quickly to the
east. Northeast breezes will freshen overnight, inducing weak
low-level convergence across the island chain. We nudged rain
chances up slightly overnight to 20-30%. An extended period of
moderate to fresh easterlies are expected Wednesday through Friday
night as the high pressure system takes on subtropical aspirations
across the western north atlantic. A frontal system may die
across the gulf of mexico Friday night through Saturday night.

Once again, a cold air tease for the florida keys, although we
will need to watch out for any vigorous convection over the gulf
trying to cold pool towards the east-southeast. Low level ridging
will attempt to rebuild across florida Sunday through Tuesday,
marking a return to the east- southeasterlies. We highlight 30-40%
rain chances Thursday through Tuesday, although there are no
identifiable moisture surges apparent on satellite derived
moisture products.

Marine
No current watches, warnings, or advisories. From synopsis, a
ridge of high pressure will linger over south florida this
evening. High pressure currently centered over the mississippi
river valley will retreat into the western atlantic Wednesday
through Saturday.

Aviation
Vfr and light east to southeast breezes will prevail at the eyw
and mth terminals through the evening. Gentle northeast breezes
will infiltrate the terminals around midnight, which may introduce
brief rain chances. The confidence in the amount of low-level
moisture convergence is low at this time.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
