area forecast discussion
national weather service key west fl
954 am edt Sat may 27 2017

Discussion
The 'ghost line' mentioned in the previous forecast discussion
indeed brought a nearly solid but narrow band of showers inside
the reef from sombrero key westward, which rapidly dissipated
prior to 9 am.

High pressure in the 700-500 mb remains with axis across north
florida with a near-surface col-region poised to remain in place
near the florida keys. Mesoscale processes should dominate this
afternoon with afternoon mainland seabreeze and surface ridge
across the eastern gulf imparting a backing light northerly flow
across the southeast gulf of mexico. The 850-700 mb moisture
convergence axis seen this morning across the florida straits
should drift a bit southward today, and progged soundings today
reflect that with slight decrease in column moisture across the
keys.

While some puffs of moderate cumulus are possible over the lower
keys once again, the chance for measureable rainfall will remain
slight today. No changes are planned for the public zone and
related gridded forecast data.

Marine
At this time, no watches, warnings, advisories or cautionary
headlines are expected through at least Tuesday. Light and
variable winds are expected across the florida keys coastal waters
this afternoon. An afternoon seabreeze should turn winds southerly
over florida bay, with high pressure in the eastern gulf of mexico
likely backing winds from east to north over waters north of the
lower keys. Beyond the reef, a light and steady east to southeast
wind of 5 to 10 knots should continue through the afternoon.

Aviation
A thin line of slow-moving showers near the lower keys has recently
rained out. The tempo for sub-vfr conditions at the keyw terminal
will be removed in the very near term. ExpectVFR conditions to
pervail there and at the kmth terminal through the bulk of
theforecast period with light easterly or variable winds.

Climate
On this date in 1894, the low temperature in key west dipped to 70
degrees. This is a long-standing low temperature record for may 27
in the city since temperature records have been kept since 1871.

Key watches warnings advisories

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.
