area forecast discussion
national weather service key west fl
250 pm edt Mon oct 14 2019

Discussion
Water vapor imagery highlights a broad area of mean-layer ridging
over the gulf of mexico. A weakened surface high over the western
north atlantic stretches west across north-central florida.

Satellite derived moisture products from cimms mimic reveal an
erosion of the deep tropical moisture across the bahamas and
southern florida, corroborated by the 12z kkey, kmfl, and mynn
raobs.

Gentle to moderate east-southeasterly breezes prevail across the
florida keys. Temperatures are in the upper 80s with dewpoints in
the mid 70s. Skies are mostly sunny and the kbyx radar detects a
few showers dragging through the lower keys.

Forecast
Forecast reasoning has not changed appreciably in the last 72
hours. The mean- layer ridge over the gulf of mexico will control
the weather through the next several days as it lumbers to the
east, then southeast to near cuba. The low level ridge axis
initially across central florida will sag southward in tandem
with the upper ridge's trek towards the western caribbean. Rain
chances and breezes will continue to trail off tonight and
Tuesday as the low level ridge axis approaches the keys. Slim rain
chances and light breezes are expected Tuesday night through
Wednesday night as the low-level ridging parks across the keys.

The tail-end of a frontal system will brush through florida
Thursday and Thursday night, in concert with lower, mid to upper
level heights across the gulf of mexico. Dewpoints may try to fall
into the lower 70s across the keys Thursday night and Friday as
the tail-end erodes over southern florida. East southeasterly
breezes and rain chances will increase Friday night through
Saturday night as the subtropical ridge rebuilds over the western
north atlantic.

Marine
No current watches, warnings, or advisories. From synopsis, high
pressure over the western north atlantic will maintain gentle to
moderate easterly breezes across the keys coastal waters tonight
and Tuesday. The ridge axis will shift southward across the keys
late Tuesday night through Thursday night, lending to light
breezes. Weak high pressure will build over the carolinas on
Friday.

Aviation
Vfr conditions are expected at both eyw and mth terminals for the
rest of the afternoon and evening. Only anticipating a few cumulus
clouds around 2500 feet across the island chain, with easterly winds
near 10 knots through 06z.

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.
