.KEY MESSAGES...
Issued at 155 AM EDT Tue May 26 2026

- A High Risk of life-threatening rip currents continues at all
  Atlantic beaches today. Rough surf will exist due to persistent
  onshore winds. Please stay out of the ocean.

- The greatest chance for a few storms (40-50%) resides just west
  of Greater Orlando late this afternoon and evening. On
  Wednesday, chances increase to around 60-70% over the interior.
  A few of the storms will be capable of producing wind gusts to
  around 50 mph, particularly on Wednesday.

- For all of east central Florida, high coverage of showers and
  storms is expected each day from Thursday through the weekend.
  While beneficial to the ongoing drought, areas that see multiple
  rounds of heavy rain will need to be monitored for flooding.

.DISCUSSION...
Issued at 155 AM EDT Tue May 26 2026

             -----------Synoptic Overview-----------

Monday evening objective analysis showed a sprawling ridge at
H5, with heights exceeding 588 dam along the Atlantic coast from
Norfolk, VA to the Florida Keys. Its center remains well offshore,
to the north of The Bahamas. Mid-level (H7 / 10 kft) moisture
has decreased substantially over the Florida Peninsula, as was
forecast. Through Wednesday, the associated surface high-pressure
axis remains north of Central Florida, and mid-level moisture
will only slowly increase beginning on Wednesday.

In the polar jet stream across N America, a pronounced omega
block is slated to develop this week. As the digging trough on
the eastern flank of the block drifts into the NW Atlantic
beginning Thursday, ridging over Florida will collapse. This is
expected to send the near-surface high-pressure axis south of the
area by Friday. Additionally, a shortwave trough, currently over
the Sonoran Desert, is forecast to slowly progress eastward and
into the Gulf by week`s end. Ahead of it, the 25/12Z ensembles
transport deep Gulf moisture and embedded weak vorticity eastward
toward the peninsula. Once it reaches the area beginning Thursday,
this anomalous moisture remains in place at least through this
weekend.

With PWAT values in excess of the 90th percentile, the encroaching
shortwave trough, and weak to offshore boundary-layer flow,
multiple rounds of unsettled weather should result beginning late
this week and through the weekend. By around next Tuesday, a weak
front associated with the trough over the Northeast U.S. may
approach the state. Cluster analysis suggests that guidance is
nearly evenly split on whether this late-season front will clear
Central Florida or stall nearby. Climatology would lean toward a
stalling front, which would prolong unsettled conditions well into
next week.

             -------Sensible Weather & Impacts-------

Today - Wednesday...

Little change to our persistent weather pattern is expected
today. With some drier air aloft, very similar conditions to
our Memorial Day are forecast. One subtle difference is that the
hi-res models give a slightly better chance (50%) for late-day
and evening showers and storms generally over Lake County, to the
west of Greater Orlando. Aside from a few morning showers or a
quick storm, the coast should be mainly dry today. Temperatures
will continue to run a few degrees above normal, particularly at
night along the coast. Breezy southeast winds continue, with a
few gusts from 20-30 mph by afternoon.

Rough surf will exist at our beaches today, and a High Risk of
life-threatening rip currents continues. Beach-goers should refrain
from entering the surf.

A few more showers may develop along the coast tonight and early
Wednesday. By Wednesday afternoon, slightly higher moisture works
in from the Gulf. With the surface ridge axis still to our north,
this should focus greater shower and storm chances from Lake
George to Orlando to Sebring and points westward (50-70%), with
30-40% chances closer to I-95. Model proximity soundings reveal
substantial DCAPE due to the lingering effects of dry air aloft,
which may promote at least a low chance for wind gusts approaching
50 mph in the strongest storms on Wednesday afternoon and evening.

Thursday - Weekend...

Deeper moisture really surges in here beginning on Thursday. With
the high-pressure axis on its way south and southwesterly flow
aloft, numerous showers and storms should form and push toward the
east coast by Thursday afternoon. These could also be somewhat
strong with at least a low chance for wind gusts of around 50 mph.
Frequent lightning will also remain a threat.

Light offshore flow becomes established beginning Friday, pinning
any sea breeze near the coast. Increasing cloud cover will be a
harbinger of the copious moisture in place over Central Florida.
It will not take much daytime heating to spark additional rounds
of showers and storms each day. While the rain will help drought
conditions, the highly efficient rain rates may cause some ponding
and/or flooding, especially for urban locales. Rainfall tallies
of 1-2.5" should be relatively common through this period, with a
10-20% chance of exceeding 3".

High temperatures should range generally in the mid to upper 80s,
with lows in the low/mid 70s. Expect very muggy conditions.

Early Next Week...

As mentioned in the overview, there is a fair amount of disagreement
regarding how long this unsettled weather pattern will stick
around. Once we reach June, it becomes very difficult to get a
clean cold frontal passage in Central Florida. We currently favor
a solution that keeps the continental air bottled up to our north
through at least Tuesday. With that in mind, high coverage of
showers and storms should persist. Statistical guidance tends
to agree with that assessment, with rain chances above 70% on
both Monday and Tuesday. Locally excessive rainfall will remain a
concern. Temperatures look to stay a bit below normal due to the
amount of cloud cover that is forecast.

.MARINE...
Issued at 155 AM EDT Tue May 26 2026

To the south of an axis of strong high pressure, fresh onshore flow
continues over the local Atlantic. This is producing poor boating
conditions, particularly behind the afternoon sea breeze. Little
change is forecast through Wednesday. The surface ridge axis will
then push southward on Thursday before reaching the Florida Straits
on Friday. Winds should decrease as this occurs. Only isolated
showers and storms are forecast through Wednesday. Then, showers
and storms will become more numerous beginning Thursday. Some of
the storms late this week will have the potential to push offshore,
bringing sudden wind gusts and higher seas.

SE winds 12-18 kts through Wednesday, becoming S 10-15 kts on
Thursday, then variable 5-10 kt on Friday. Higher winds and gusts
near storms late in the week. Prevailing seas 3-5 ft through
Wednesday, decreasing to 2-3 ft Thursday and Friday.

.AVIATION...
(12Z TAFs)
Issued at 635 AM EDT Tue May 26 2026

ISOLD SHRA lifting north this morning and patchy MVFR CIGs will
affect some coastal terminals hence the TEMPOs to start the 12Z
package. Additional SHRA could develop farther inland after 14Z
as a diffuse east coast sea breeze develops and pushes inland.
Maintaining VCSH at MCO as CAM guidance shows bulk of convection
should be (just) west. VCTS at LEE may eventually need a TEMPO
roughly 22Z-01Z.

SE winds will quickly increase 15-20 kts with gusts 25-29 kts on
the coast. Similar peak gusts at interior terminals (MCO/SFB) Tue
aftn but not as frequent.
