.DISCUSSION...
Issued at 938 PM EDT Sat May 4 2024

Currently - A strong high pressure system centered broadly over
New Brunswick stretches a robust ridge south southwestward along
the Atlantic coast that then arcs southwest and west across the
Gulf of Mexico. This is generating moderate to fresh easterly
breezes across the Keys this evening. This easterly flow is
maintaining slightly above normal temperatures, which are
currently near 80. Dew points remain near 70. This evening
sounding indicated some lower level inhibition with a neutral to
backing lower level wind profile. Precipitable water is down a bit
over the past 24 hours and is now sitting just below one inch.
All this, along with no convective support has resulted in no
shower activity along the island chain. There has been a few weak
showers moving into our deep gulf waters and along maritime
boundaries over the outer eastern straits.

Short Term Update - The previously mentioned ridge will remain in
firm control of the broader are through the overnight period. This
will lead to continued moderate easterly breezes across the island
chain. While showers have thus far not been an issue, they cannot
be ruled out for the overnight. Forecast soundings suggest the
lower level inhibition will weaken substantially while moisture
will tick upwards. Expect lows in the mid to upper 70s range with
dew points remaining near 70.
