...New UPDATE, AVIATION...

.FOR THE EVENING UPDATE...
Issued at 717 PM EDT Sun May 18 2025
No change to the overall pattern across the Florida peninsula as
high pressure surface and aloft will continue to dominate the
weather over the area. Some high cirrus currently over west
central and southwest Florida will exit east of the region during
the next several hours, with skies becoming mostly clear. Some
late night patchy fog is possible tonight mainly across the nature
coast.  Overnight temperatures will run above climatic normals
with lows in the mid to upper 60s north...and the lower to mid 70s
central and south.

On Monday, skies will start out mostly sunny, but will give way
to some high cloudiness during the afternoon hours. Strong
subsidence over the forecast area will again lead to very warm to
hot temperatures. Highs will run in the mid to upper 80s along the
coast as temperatures will be held down due to onshore winds off
the relatively cooler Gulf waters, but will be in the lower to mid
90s inland.

&&

.DISCUSSION...
Not much change to the overall forecast thinking from yesterday.
Ridging aloft over the Gulf will generally remain over the region
through the next several days while surface high pressure
stretches across the peninsula from the Atlantic. This setup will
keep a relatively light southwest low-level flow in place across
the local area and keep rain chances low. The main story will be
the heat, with highs each day topping out in the mid to sometimes
upper 90s away from the coast and heat indices reaching the low
100s.

As we head toward the end of the week, ridging starts to flatten as
troughing moves by to our north. An associated frontal boundary will
move into the southeast and eventually over Florida on Thursday,
bringing just a 20-30% chance for rain before high pressure builds
back in for Friday and next weekend.
