927 am est Sat feb 24 2018

Discussion In the middle and upper levels(700-200 mb), latest
available satelitte imagery overlaid with model streamline
analysis as of 900 am, seems to depict lower amplitude ridging and
troughing across the entire CONUS (east to west) than 24 hours
prior, indications of a slowly flattening middle and upper
pattern, which is more inline with the approach of the end of
meteorological winter late next week. Across the lower latitudes,
the axis of a deep and warm ridge is oriented in the western
atlantic from near 30n 70w southwestward towards southern mexico.

At the surface and in the lower to middle levels, (surface to 700
mb), latest satelitte imagery overlaid with marine and land
observations and analysis as of 900 am, detail a frontal boundary
located from eastern maine southwest to central texas. Closer to
the keys, the center of near 103 mb surface ridging was located
near 32 N 70 w, with an attendant axis extending west southwest to
across northern florida attm. The 12z morning sounding
illustrated moderate to occasionally fresh east to southeast flow
from the surface to about 600 mb, with moisture remaining below
800 mb and total columnar pwat at 1.16 inches, which is only about
a tenth of an inch more than 24 hours ago.

Currently As of 900 am, skies are partly cloudy across the
islands and surrounding waters. Radar does show isolated showers
in the florida straits and impacting portions of the middle keys,
with a few showers just off of the lower keys attm, and widely
scattered showers affecting a 25 nm radius of fort jefferson
national monument out in dry tortugas national park about 70
miles west of key west. Temperatures, outside of islands impacted
by a quick shower across the islands are already in the upper 70s
with dewpoints in the upper 60s to near 70. C-man stations along
the florida reef are east to southeast at 15 to 20 knots and gusty.

Island sensors are near 15 mph but gusty as well.

Short term Rest of the day and this evening, latest forecast
soundings maintain moderate east to southeasterly flow across the
islands and surrounding waters. Temperatures will reach between 80
and 85 degrees once again. Will also be issuing an update to
decrease any shower coverages to isolated. Aforementioned surface
ridging across northern florida will weaken slightly today and
tonight resulting in winds decelerating slightly this afternoon
and evening.

Marine This afternoon and evening, scec conditions will
continue across the florida straits this afternoon, but headlines
across hawk channel and the offshore gulf waters will only be in
effect early, as winds come down, remaining near or close to 15
knots through the morning hours tomorrow. Winds and seas will come
down more during Sunday, making this a much better day for
non sailing recreational boaters then this afternoon.

Aviation Vfr conditions will prevail at both the key west and marathon
terminals through this afternoon and early evening. There is a
slight chance of a quickly passing shower, main in the remainder of
the morning hours, which my result in very brief MVFR conditions at
either terminal. Surface winds will be from the east southeast near
12 knots.

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.
