Discussion
Temperatures range this morning from the mid to upper 70s across
the florida keys island chain, a bit warmer than yesterday am.

Kbyx weather radar has been detecting scattered showers overnight
that are ongoing early this morning across western portions of the
waters, including portions of the florida straits and southeastern
gulf of mexico. This activity is occurring on the eastern side of
a surface trough of low pressure where there is still modest
upglide occurring. Goes-east imagery indicates much less low-
level cloud coverage compared to yesterday, but increased cirrus
coverage.

Short term
For today, expecting scattered showers to remain west of the
island chain and probably decrease in coverage as isentropic
upglide becomes less efficient. The aforementioned surface trough
will continue to influence our area, perhaps even slightly
retrograding towards our southeastern gulf waters while becoming
more diffuse. Winds are expected to veer towards the southeast and
weaken today in response, mainly in areas north and west of the
island chain.

The larger scale ridge of high pressure influencing our area will
weaken through tomorrow, with winds decreasing into the 5 to 10
knot range across our nearshore and coastal waters. By Tuesday
night a weakening cold front approaching the region will bring
significant changes, with winds becoming north to northeast and
increasing to the 10 to 15 knot range. Winds should peak Wednesday
into Wednesday night with building seas across the area.

Long term
The fresh injection of high pressure into the southeastern conus
should keep winds up across our area through the end of the work
week. Thanksgiving day could see the highest potential for
rainfall, and pops have been bumped up to 30% along the island
chain as a result. Near climatology 20% chances have been
maintained for all other periods. The front will bring a small dip
in temperatures and dew points, but nothing to write home about.

Low confidence in the forecast heading into the weekend. Global
models continue to struggle (understandably) with the strength of
a mid-level shortwave and resultant low pressure along the
northern gulf coast. The forecast is heavily weighted towards the
weaker GFS solution since uncertainty remains high.

Marine
Gentle easterly to southeasterly breezes expected today as high
pressure weakens and loses influence over the area. By Tuesday
night a weakening cold front moving into the area will freshen
winds out of the north and northeast to moderate breezes with
seas building in response.

Aviation
Vfr conditions are expected to prevail at both eyw and mth through
Tuesday morning. Intermittent bkn ceilings between 4000 and 8000 ft
will persist through the morning hours, but the general trend should
be upward through the afternoon as these cloud layers scatter out.

Winds will generally remain below 10 kts out of the east-southeast
at both terminals. Check out aviationweather.Gov for a plethora of
aviation weather information.

Climate
On this day in 1985, hurricane kate moved wnw along the island of
cuba, passing about 100 miles southwest of key west. A runoff
election for city government candidates was cancelled and
rescheduled due to the resulting inclement weather. (see

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.
