Discussion
Currently - a broad ridge to our north is responsible for light
east to southeast breezes across the florida keys. Ridging and
increasingly dry air has moved in through the lower and mid
levels. As a result, convective activity has been mostly along a
few marine boundaries and along lee side cloud lines off of the
lower keys. Meanwhile, a surface low, centered well northeast of
the bahamas, is arcing west and northwestward around the broad
high to our north.

Forecast - over the next several days, the high to our north will
strengthen as a mid latitude ridge moves eastward into the
northeast. This would tend to strengthen the local pressure
gradient and winds. However, the low northeast of bermuda will act
to counter any increase as it approaches the southeastern united
states coast. Local winds will remain light out of the east to
southeast through the first couple days of the work week. Drier
air will be established across the keys through the lower and mid
levels. However, there will remain ample CAPE and boundary layer
moisture and heat. Expect isolated to scattered convective
coverage through this period, primarily due to lee side could
build up and marine boundaries.

Heading into mid week, the low approaching the us coast will be
ejected out northeastwards as it is absorbed into a mid latitude
trough moving eastwards towards the coast. The atlantic high will
then rapidly build towards the southeast united states and
florida. Expect winds to edge upwards to a gentle to moderate east
breeze through the rest of the work week. Winds may edge up bit
further heading into the weekend as the high to our north is
reinforced by a continental high. Isolated to scattered showers
and thunderstorms will remain possible as the keys will remain
moist, uncapped, with ample cape. However, ridging through the
lower and mid levels will keep the environment less than ideal.

Day time highs will be near normal with overnight lows near to
slightly above normal.

Marine
Broad ridging to our north will maintain light east to southeast
breezes over the next couple of days. Heading into mid week, the
ridge will improve its reach across the extreme southeastern
united states and florida. As a result, expect winds to edge
moderately upwards. The ridge to our north will be reinforced by a
continental high moving into the weekend, and winds will edge
upwards again. Cautions may be required for portions of keys
waters this weekend.

Aviation
Vfr conditions will prevail at eyw and mth terminals throughout the
forecast period. Isolated showers with a few thunderstorms will
likely remain just offshore, primarily north of the lower keys. A
drier airmass has moved into the region effectively reducing
overall coverage. However, daytime heating and residual boundaries
from previous convective activity remain just north of the lower
keys and continue to act as a focusing mechanism for this
evening's activity. Winds will be southeast to east at less than
10 knots.

Climate
For september 23rd, the daily record high temperature of 92 degrees
was last recorded in 1990. While the daily record rainfall of 2.10"
was recorded for this date back in 1931. Temperature records at key
west date back to 1872, and precipitation records date back to 1871.

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.
