area forecast discussion
national weather service key west fl
935 am edt Tue mar 28 2017

Discussion In the middle to upper level(700-200 mb), latest
available model streamline analysis overlaid on top of satelitte
imagery as of 900 am depict a typically progressive early spring
middle and upper pattern, with one shortwave axis over the upper
ohio valley and the central appalachians. Upstream of that, the
northern terminus of the axis of a deep and protruding ridge is
oriented into the upper midwest from the western gulf of mexico,
and upstream of that, the axis of another narrow yet sharpening
full latitudinal trough is positioned from north central montana
down to southern arizona.

At the surface and in the lower to middle levels(surface to 700
mb), latest satelitte imagery overlaid with marine and land
surface observations and analysis as of 900 am, details the center
of 1005 mb gale located near 27n67w. Well west of that, a slow
moving cold front extends from western ny state down to north
texas. Broad weak 1018-1020 mb surface high pressure exists
across the florida peninsula and adjoining waters. The 12z
sounding illustrated a gentle to moderate mostly east flow just
off the surface becoming light and variable at 850 mb then gentle
and northerly at 700 mb increasing above that. The column remains
seasonably dry with columnar pwat at only .90 inches.

Currently As of 900 am, skies are mostly sunny across the
islands and adjoining waters, with isolated very light showers
confined to the florida straits. Temperatures are in the middle to
upper 70s with dewpoint in the middle 60s across the island chain.

C-man stations are generally NE to E near 10 knots except 10 to 15
knots out at sand key and pulaski shoal light.

Short term Rest of today, broad weak surface ridging to the
north, will work in combination with the increasing affects of the
mesoscale south florida thermal trough, as we enter a period of
stronger early spring insolation. Ample dry air in the middle
levels will be associated with subsidence. The result at this time
of year is always light to gentle northeast to east across the
islands and adjoining waters, with gentle to moderate east winds
out over the straits. The ongoing forecast handles this well and
no changes are foreseen on the morning update cycle. Temps in the
mid 80s will be accompanied by sunny skies and comfortable levels
of humidity.

Marine Winds will be gentle to moderate, favoring the easterly direction
through the next several days. No advisories or cautionary
headlines for small craft are expected.

Aviation
Vfr conditions will prevail at eyw and mth today and tonight.

Sustained east winds of 10 to 15 knots from just off the surface to
about 3,000 feet will decrease to 5 to 10 knots this afternoon.

Climate
On this date in florida keys weather history, in 1994, the high
temperature in key west was 88 degrees. This set the daily record
for maximum temperature measured in key west on march 28th, a record
which still stands 23 years later. Temperature records at key west
date back to 1872.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
