.AVIATION...
(18Z TAFS)
Issued at 255 PM EDT Sat Jun 14 2025

VFR conditions will prevail at both EYW and MTH for the rest of
today and into tonight. While a shower cannot be ruled out near
either terminal, low coverage and certainty in location and timing
will leave mention out of the TAFs for now. Near surface winds
will be out of the east to southeast a near 10 knots with
occasional gusts to near 15 knots.

.DISCUSSION...
Issued at 1050 AM EDT Sat Jun 14 2025

Not too much has changed across the Florida Keys this morning.
Shallow strips of fair weather cumulus are streaming across our
area from the southeast with a few clusters of showers north of
the Cay Sal bank and west of the Dry Tortugas (similar to
yesterday). KBYX radar reflectivity notes shower activity near the
island chain is on the decline while the previously mentioned
locations continue to bubble with shallow convection. Meanwhile,
the eastern Straits of Florida have really dried out as CIMSS
MIMIC PW depicts a tongue of lower values advecting in from Cuba.
Thunderstorm activity has been notably lower than previous days so
far as this morning`s KKEY sounding shows more dry subsidence
intruding into the mid to low levels. This should help suppress
deep convective development throughout the day along with weak
anticyclonic surface flow. Overall sparse cloud cover has
temperatures observations up into the mid to upper 80s before the
afternoon once again making for a mildly oppressive near normal
summer day taking dewpoints in the mid to upper 70s into account.
East to southeast breezes along the reef are still moderate in
magnitude but have slackened a touch from before sunrise. The
forecast looks to be on track with no changes needed at this time.

.FORECAST...
Issued at 430 AM EDT Sat Jun 14 2025

A fairly stable weather pattern is established across our area
thanks to the surface through lower level Atlantic ridge
stretching westward past Florida. Meanwhile, mid and upper level
ridging is in place across our broader area. Surface winds have
freshened modestly late this evening and are moderate out of the
southeast. This steady flow is maintaining seasonable surface
temperatures and dew points. Precipitable water is near normal at
around 1.5 inches and inhibition is very limited. However, lower
level dry layers and overall anticyclonic flow is keeping
convective activity isolated.

No significant changes to our synoptic pattern is expected.
Surface through mid level ridging will remain in control. The
upper level ridge is expected to weaken as weak troughing pinches
off in the western Gulf. However, for our area, this means the
flow aloft will become nebulous. As a result, the prolonged
stretch of gentle to moderate east to southeasterly breezes will
continue through the weekend and well into next week. Winds will
tend to peak in the evening and overnight and lull during the
day. CAPE will remain ample, precipitable water near normal, and
inhibition limited to non existent. However, the continued
existence of lower to mid level dry layers and the dominant
anticyclonic flow will help to mitigate convective coverage. Have
nudged down pops to slight chance through the forecast. Expect
continued seasonable temperatures with highs in the upper 80s,
lows in the lower 80s and dew points lingering in the mid 70s.

.MARINE...
Issued at 1050 AM EDT Sat Jun 14 2025

No watches, warnings, or advisories are currently in effect for
the coastal waters of the Florida Keys. From synopsis, strong
high pressure centered just east of Bermuda will remain in place
for the next several days. This will support moderate to
occasionally fresh breezes. The high will drift a bit
southeastward over the weekend into early next week, leading to
slightly weaker breezes.

.CLIMATE...
On this day in 1957, the daily record high temperature of 94F was
recorded in Key West. Temperatures records for Key West date back to
1872.
