.DISCUSSION...
-- Changed Discussion --
Issued at 406 AM EDT Fri May 24 2024
With the exception of a few waxing and waning showers well to the
north of the Lower Keys early this morning, weather conditions
will continue to remain unremarkable through the end of the week.
Skies will continue to be mostly clear with only some benign
clouds skirting across the sky as high temperatures during the day
climb to near 90F. East to southeasterly breezes near 5 mph won`t
offer much relief from the seasonably warm temperatures, but dew
point temperatures in the lower 70s will help to keep the heat
index from soaring into the triple digits like we have already
seen this month.

The synoptic pattern will make some changes when the dominant
ridging pattern tries to reposition itself over the course of the
beginning of the week, including the Memorial Day holiday. The
resulting weather conditions will not see much of a change on
Sunday, but chances for showers and thunderstorms are reintroduced
for Monday through Thursday. The chance of any activity is still
low, 10 percent on Monday and 20 percent from Tuesday onward, but
all it takes is one shower to put a damper on holiday activities.
Another aspect of the forecast for next week is guidance
suggesting that dew points start to climb again into the middle
and possibly upper 70s. This is not anything set in stone yet, but
this could lead to sweltering and dangerous heat indices once
again.

Light to gentle east to southeast breezes will continue through
the end of the week as high pressure will remain in place. During
the later half of Sunday, breezes will clock to a southeasterly to
south direction and modestly freshen as the high pressure shifts
its position.
