.DISCUSSION...
Issued at 1027 AM EST Wed Jan 8 2025
It is a chilly early January morning across the Florida Keys.
Temperatures along the Island Chain are in the upper 50s to near
60 degrees with dew points in the lower 50s. KBYX radar is quiet
and GOES 16 Visible satellite imagery shows lots of stratocumulus
clouds throughout the area, especially across the western portions
of the Keys. There are also some high level cirrus clouds
streaming from west to east across the area. Marine platforms
around the Keys are observing northwest to north breezes between
10 to 15 knots with Island Chain communities observing near 10
mph.

.SHORT TERM FORECAST...
The 12z morning sounding displays a sharp inversion between 925
and 900 mb with stout dry air above this layer. The wind profile
displays backing with height switching from due north to
northwesterly. This is indicative of CAA- cold air advection still
ongoing across the Keys. The PWAT value measured was 0.76 inches
which is between the 10th and 25th percentile for the date. Based
on the above, outside of the stratocumulus clouds, no changes
expected to the ongoing forecast. For now, expect continued
intervals of clouds and sunshine.

.MARINE...
Issued at 1027 AM EST Wed Jan 8 2025
There are currently no watches, warnings, or advisories in effect
across the Florida Keys coastal waters. From synopsis, moderate
to occasionally fresh northerly breezes will continue through
Thursday across the Keys coastal waters, as a large area of high
pressure moves slowly eastward across the central and eastern
United States. Breezes will then veer from northeast to southeast
Thursday night through Friday night, as low pressure and an
associated cold front moves east across the Gulf of Mexico. The
next front is forecast to weaken while slipping through the Keys
waters Saturday night.

.AVIATION...
(15Z TAFS)
Issued at 1027 AM EST Wed Jan 8 2025
Persistent low stratus and stratocumulus observed in satellite
mean that intermittent to continuous MVFR CIGs will continue for
now, although trends and guidance suggest a return to VFR sometime
this afternoon. Northerly crosswinds continue through the period.
