Discussion
A cold front pushed through the florida keys on Thursday. Behind
the front, northwest to north winds surged to near 25 knots, at
times gusting above 30 knots. Winds are not quite as intense at
this hour, although most locations are sustained above 20 knots.

Dewpoints have steadily fallen since last evening, now nearing 60
for most locations. Temperatures have been slow to fall, with the
lower keys ranging from 73 to 75 degrees, with locations across
the upper keys in the upper 60s. Infrared satellite imagery
reveals a large expanse of low level stratus across the island
chain, although there appears to be some breaks upstream. The kbyx
radar is echo free aside from a few drizzle streaks over the
straits of florida.

Forecast
Very few changes to the forecast reasoning this cycle.

Temperatures this morning should continue to fall after sunrise.

The lower keys should be near or just above 70, with locations
across the upper keys in the mid 60s. The lowest dewpoints and
humidity since last spring will settle into the island chain this
afternoon as the mainland drains. Highs should struggle to reach
75. Rain chances have been removed. Skies will briefly clear in
the lee of south florida. Thereafter, high pressure centered over
the northern gulf coast and the southeastern unite states will
persist. Moderate northeast to east breezes will occasionally peak
and lull over the next several days. Rain chances are slight
through the forecast period, although there is some uncertainty to
the rain forecast Sunday through Monday night. There appears to
be some evidence that the frontal zone will lift northward across
the island chain. We increased rain chances to 30% on Monday to
account for this pseudo warm frontal passage. A reinforcing shot
of continental air is possible Tuesday night and Wednesday, just
before the holiday.

Marine
Small craft advisory remains in effect for all coastal waters of
the florida keys. North winds 20 to 25 knots will prevail this
morning, then diminish in the afternoon. Seas up to 7 to 8 feet
across the deeper waters of the southeastern gulf of mexico and
the straits of florida will prevail this morning. From synopsis,
strong northerly breezes this morning will diminish this
afternoon. Moderate northeast to east breezes will occasionally
peak and lull, tonight through Tuesday, as high pressure persists
over the southeastern united states.

Aviation
12z terminal forecast discussion:
expecting mainlyVFR conditions to prevail through the forecast
period with some MVFR ceiling impacts this morning. The edge of a
broken overcast deck is right along the florida keys, so expect
clearing skies by mid-morning at mth with clearing already beginning
at eyw. Strong northerly winds persist today with gusts near 20 kts
at mth and over 20 kts at eyw.

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.
