.KEY MESSAGES...
Issued at 125 PM EDT Fri May 9 2025
- A few strong to severe storms are forecast this evening,
particularly along the I-4 corridor and Space Coast. Damaging
wind gusts to around 60 mph, hail to quarter size or greater,
and frequent lightning are the primary threats.
- Unsettled weather persists through early next week as unusually
high moisture remains locked over Florida. There remains a low
chance of a few strong to severe storms, and the risk for some
flooding from excessive rainfall increases by Monday and early
Tuesday.
- Drier weather returns by the middle of next week. Then,
temperatures turn hot late next week.

.DISCUSSION...
Issued at 125 PM EDT Fri May 9 2025
-----------Synoptic Overview-----------
This Friday afternoon, weak shortwave ridging is in place over S
Florida. Ripples of subtropical jet stream energy are moving through
the N Gulf and N Florida on the southern flank of a trough across
the Ark-La-Tex. Guidance is in excellent agreement with the
evolution of the pattern over the coming 3-5 days. Within the next
36 hours, ridging over the Rocky Mountains is forecast to build over
the top of the trough, causing it to cut off over Louisiana through
Monday. Early next week, a stronger trough entering the Pacific
Northwest should allow the cut-off low to lift toward the Mid-
Atlantic by Wednesday as it fills/weakens. Surface low pressure is
expected to form on the northern Gulf Coast this weekend, lifting
inland with the trough early next week.
Presently, an axis of anomalously high total moisture resides from N
Florida westward over much of the Gulf. This moisture axis will
likely remain in place over N Florida and the NE Gulf through
Sunday; in concert with the lifting trough, deeper moisture should
sweep eastward over the entire peninsula from Monday into early
Tuesday. Associated with the surface reflection of the trough, an
ill-defined surface cold front will form but is likely to undergo
frontolysis by mid-week. Regardless, drier air should be advected
over the state by late Tuesday or Wednesday.
09/00Z cluster analysis reveals moderate to strong consensus in the
grand ensemble late next week. Nearly all members build a reservoir
of above-normal H5 heights over the Gulf and Mexico by next Thursday
and Friday. This ridge is then forecast to overtake the Florida
peninsula next weekend. In response, moisture levels only return to
mid-May norms amid strong subsidence. 5 KFT (H85) temperatures jump
from +15 deg C on Wednesday to +19 deg C next Saturday.
--------Short-Term Mesoanalysis--------
Strong insolation has resulted in temperatures jumping through the
80s to near 90 deg F, and ample moisture resides in the PBL. An axis
of enhanced surface theta-E is likely to result over the I-4
corridor this afternoon. Visible satellite currently shows mostly
clear skies with a cu field beginning to develop. Guidance and the
09/15Z XMR sounding indicate MLCAPE values approaching 1500 J/kg and
bulk shear of 30-40 KT over the area. Right along the sea breeze
boundary, the modified XMR sounding indicates that backed boundary-
layer winds should increase 0-1 KM SRH to around 100 m^2/s^2. H5
temperatures have cooled to around -12 deg C in tandem with a very
weak mid-level disturbance passing over N Fla. Convective initiation
is expected from the combination of ample instability and weak PVA
with sustenance from subsequent boundary and sea breeze interactions.
-------Sensible Weather & Impacts-------
This Afternoon - Tonight...
Rain and storm chances increase to 60-80% this evening over the I-4
corridor, decreasing as you travel toward the southern Space Coast
and Treasure Coast. The primary threats from storms are gusty winds
from 40-50 mph and small hail, with at least a 15% chance of wind
gusts of 60 mph or greater. There is also a low chance of severe
(1"+) hail and a very low risk of a tornado from storms interacting
with the sea breeze. Frequent lightning and torrential rain should
accompany these storms. The highest coverage for this activity looks
to range from 4 PM to 9 PM. Quieter overnight with only a few
showers lingering.
This Weekend...
While the axis of deepest moisture should hold just west and north
of Central Florida, the northern half of our district (particularly
the I-4 corridor) should remain in an environment favorable for 50-
70% coverage of mainly afternoon and evening showers and storms. One
or two stronger storms (gusty winds to 50-60 mph and coin-sized
hail) remain a low threat with areas experiencing repeated storms
most at risk for some brief, minor flooding issues. Through Sunday
night, reasonable high-end rainfall amounts are 3-5" over the I-4
corridor; areal forecast averages are closer to 1.5-2.5". Expect
those high-end tallies on a very sporadic basis with a 1-in-10
chance of occurrence. South of Melbourne to Okeechobee, storm
chances are lower (30-50%). Near to above-normal temperatures
persist, particularly at night due to the higher moisture.
Monday - Tuesday...
Timing is still somewhat in question, but as the low lifts by to our
north, a ribbon of rich moisture and a weak front should cross
through the state beginning on Monday through at least midday
Tuesday. This holds our highest chance for widespread, soaking
rainfall. Despite the drought, too much of a good thing may start to
pile up flooding concerns, especially for those places that pick up
repeated rains this weekend as well. The 09/00Z GFDL C-SHiELD may
have a fairly good representation of this setup, showing a slow-
moving band of rain and storms crossing the peninsula from Monday
afternoon through Monday night. Despite plentiful cloud cover,
proximity soundings reveal some instability and wind shear
associated with this feature. This coincides with ECMWF extreme
forecast indices of unusually high combined CAPE + shear on Monday.
If destabilization can occur, the severe weather threats would
include damaging wet microburst wind gusts and brief tornadoes.
Despite the weak surface frontal reflection, well-defined wind
shifts aloft should introduce progressively drier air to the state
sometime on Tuesday, lessening rain chances from west to east. Highs
should generally be in the 80s on both days, coolest (and below
normal) on Monday.
Wednesday - Next Weekend...
With drier air and high pressure overtaking the state, a stretch of
largely rain-free weather is anticipated for the second half of next
week. Statistical guidance blends appear to be hanging onto low rain
chances too long after the early-week disturbance exits, requiring
modest adjustments to force a dry mostly dry forecast - except for
Wednesday when a lingering shower is indicated along the Treasure
Coast.
Impressive warm advection late next week should ensure a steady
warming trend toward some of our hottest weather so far this year.
In fact, the probability of temperatures 95 deg F or greater is
already at 20-30% over portions of the interior by next weekend.

.MARINE...
Issued at 125 PM EDT Fri May 9 2025
The local Atlantic will be influenced by a high-pressure center well
offshore, low pressure developing over the N Gulf Coast, and a warm
front along the Panhandle. Moderate SSE breezes (10-17 KT) are
forecast through the weekend, freshening to 15-20 KT on Monday.
Local seas of 3-4 FT persist, locally increasing to 5 FT well
offshore on Monday. A weak cold front should approach the local
Atlantic on Tuesday with winds and seas beginning to decrease as the
pressure gradient relaxes.
The greatest impact on boaters will be occasional showers and gusty
offshore-moving storms. Through early Monday, the highest coverage
of this should be from the Space Coast northward. By Monday into
Tuesday, the entire local Atlantic has high chances for showers and
storms. Mariners should keep an eye on the sky for changing
conditions, use a NOAA Weather Radio or mobile device, and stay
alert for Special Marine Warnings.

.AVIATION...
(18Z TAFs)
Issued at 125 PM EDT Fri May 9 2025
VFR continue prior to TSRA initiation this afternoon. This forecast
is similar to the previous, with TEMPOs for DAB to MLB and points
west (excluding LEE). Confidence is highest in TSRA impacts
(MVFR/IFR) at DAB/SFB/MCO/ISM 20-24z as the ECSB moves inland and
collides with the west coast breeze. Strong/severe wind gusts, hail,
and frequent lightning are possible. After 00z, activity will slowly
push back toward the coast with a diminishing trend after 03z. VFR
and VRB wind returns overnight before SSE winds return to ~10-12 kt
by 14-16z Sat. Additional TSRA are forecast to develop from LEE-MCO
after 20z Sat.
