Discussion
Currently
Isolated showers are detected by kamx kbyx off the eastern florida
straits, and have occasionally clipped the upper keys this
morning. Skies are partly cloudy across the island chain, with low
level flow out of the east-southeast, and upper flow out of the
northwest, as high clouds progress ahead of the low pressure
system centered in the mississippi basin. Mimic imagery continues
to indicate moistening low levels across the gulf of mexico,
western caribbean, and western atlantic along the florida
peninsula and bahamas.

The 12z key sounding revealed an unstable atmosphere with ~2700
j kg of cape, a lack of low level shear, and a pwat near 1.2
inches.

Short term
The stacked cyclone in the mississippi river valley will progress
east-northeast into the tennessee river valley as the high
pressure cell (anchored off the new england coast) shifts
northward away from the keys. The resulting pressure gradient will
decrease locally, leading to relaxing breezes today. Another weak
surge in the winds may occur after midnight tonight for a brief
period of time before relaxing again, as the transition between
synoptic systems occur. Expect current conditions of slightly
above average temperatures to continue through early this week,
with dew points remaining in the low 70s.

Marine
No watches, warnings, or advisories are in place across the
coastal waters surrounding the florida keys. An expansive area of
high pressure covering the entire eastern united states will slide
into the western north atlantic ocean over the next several days,
as a weak area of low pressure migrates eastward and across the
southeast united states before lifting up the eastern seaboard
next week.

Aviation
Rest of today,VFR conditions will prevail at eyw and mth through at
least the next 24 hours. Expect a few to scattered clouds with bases
aoa fl015-025, but anyVFR CIGS will be very short lived.

Climate
On this date in florida keys weather history, in 1940, the low
temperature in key west was 62 degrees. This set the daily record
for minimum temperature measured in key west on april 22nd, a record
which still stands 78 years later. Temperature records at key west
date back to 1872.

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.
