...New KEY MESSAGES, DISCUSSION, MARINE...

.KEY MESSAGES...
Issued at 215 PM EDT Mon Jul 13 2026

- Marginal Risk (level 1 out of 5) for severe storms this
  afternoon and evening with the potential for one or two storms
  capable of frequent lightning, damaging wind gusts, and heavy
  rainfall; a brief tornado cannot be ruled out (< 2% chance)

- A similar forecast is expected Tuesday before the arrival of
  more Saharan dust which will limit rain and storm chances mid to
  late week

- Hot and humid July temperatures will lead to afternoon heat
  indices between 102-107F each day. Make sure to practice heat
  safety!

.DISCUSSION...
Issued at 215 PM EDT Mon Jul 13 2026

Currently-Tonight... Current radar imagery shows a line of
scattered showers and lightning storms developing to the west of
Lake and Volusia counties moving east towards east central
Florida. GOES-16 satellite imagery and local observations shows
mostly cloudy skies across east central Florida. Analysis charts
show high pressure extended over southern Florida with a major
shortwave trough over the Midsouth/Southeastern US. Temperatures
are currently in the upper 80s to low 90s with dew points in the
mid 70s to around 80 degrees. Heat index values are generally
between 98-107F degrees.

Scattered to numerous generally offshore moving showers and
lightning storms are forecast to develop this afternoon as
collisions occur between the sea breezes and outflow from previous
storms. This morning's 15Z XMR sounding shows MLCAPE at 1,091
J/kg, MUCAPE at 3,630 J/kg, a PWAT of 1.98", 0-6km shear at 10kts,
conditionally unstable mid level lapse rates, and a 500mb
temperature of -8C. Thus, a Marginal Risk for severe storms exists
for all of east central Florida. The main hazards are frequent
lightning, damaging wind gusts up to 60mph (5-14% chance), and
heavy rainfall (1-3"+ in 30-60 minutes with a 1 in 10 chance of
rainfall amounts in excess of 3" up to 4-5" with the potential of
minor flooding of roadways and low lying areas. Additionally, a
brief tornado cannot be ruled out (<2 % chance). Additionally,
local analysis shows plenty of instability with CAPE up to 5,000
J/kg, LI up to -9, and no cap. The greatest potential for severe
storms is between until 9PM this evening beginning from
northwestern east central Florida to southeastern east central
Florida into this evening. Rain chances diminish by around
9PM/10PM as storms push offshore of the Treasure Coast. Lows in
the low to upper 70s are forecast.

Tuesday-Wednesday... A similar forecast is expected on Tuesday
with a shortwave trough over the southern US. However, there are
slightly lower precipitation chances between 40-60%. Scattered to
numerous generally offshore moving showers and lightning storms
are forecast to develop into the afternoon and evening as
collisions occur between sea breezes and outflow from previous
storms. Guidance indicates MLCAPE between 1,500-3,200 J/kg, 0-6km
shear up to 20-30kts enhanced along the local sea breeze, and
conditionally unstable mid level lapse rates, and 3KM EHI up to
1-3.5 along the coast. There is the potential for a couple to a
few strong storms capable of frequent lightning, wind gusts up to
40-55mph (< 5% chance of a storm capable of damaging wind gusts up
to 60mph), and heavy rainfall (1-2"+ with a < 5% chance of
rainfall amounts in excess of 2" up to 3-4.").

Drier weather is forecast on Wednesday as another Saharan dust
layer begins to arrive across east central Florida. Isolated to
scattered generally offshore moving showers and lightning storms
are forecast to develop into the afternoon and evening hours as
collisions occur between the sea breezes and outflow from previous
storms. The greatest chance for showers and lightning storms is
across Volusia and northern Brevard counties with offshore moving
showers and lightning storms. The potential exists for a strong
storm or two capable of frequent lightning, wind gusts up to
40-50mph, and heavy rainfall. Afternoon highs in the low to mid
90s are forecast with heat index values between 100-107F degrees.
Lows in the low to upper 70s are forecast.

Thursday-Sunday (modified previous discussion)... The surface
high will remain near to south of the area into late week and
next weekend with moisture gradually increasing once again and the
SAL diminishing. This will lead to a return of more normal
coverage of showers and storms each afternoon and evening, with
PoPs around 20-40%. Above normal heat will linger with highs in
the mid 90s for much of the area and heat index values nearing or
just below Heat Advisory thresholds. A Major HeatRisk with areas
of Extreme HeatRisk Friday and through the weekend. This level of
heat affects anyone without adequate cooling and hydration.

&&

.MARINE...
Issued at 215 PM EDT Mon Jul 13 2026

Currently-Friday (modified previous discussion)... The high
pressure over the western Atlantic will generally remain near to
south of the waters through the work week, with offshore winds out
of the W/SW during the overnight and morning hours, switching the
the S/SE in the afternoon as the east coast sea breeze forms.
Wind speeds will largely remain below 15 knots with seas 1-3
feet. Main hazard to boaters will be strong to marginally severe
offshore moving storms today and tomorrow during the
afternoon/evening. Scattered showers and storms pushing off the
coast are forecast today and Tuesday (rain chances up to 50- 60%),
with coverage of this activity decreasing through midweek. Any
storms that push offshore will be capable of producing strong wind
gusts near or in excess of 34 knots and frequent lightning
strikes.

&&

.AVIATION...
(18Z TAFs)
Issued at 131 PM EDT Mon Jul 13 2026

VFR conditions outside of convection through the TAF period.
Scattered showers and storms are ongoing across the western side
of FL this afternoon, slowly moving eastward towards ECFL.
Additional showers and storms will move eastward across the state
from the west coast this afternoon along the west coast sea
breeze. Have maintained VCTS at all inland terminals as well as at
DAB and TIX at 18Z, and having VCTS starting at MLB-SUA at 19/20Z.
No changes to the timing of the TEMPOs as of now, but will
monitor to see if adjustments are needed. SW-SSW winds around 5 KT
will shift E-SE behind the east coast sea breeze this afternoon
and increase to around 10 KT. Any lingering showers and storms
will dissipate or move out of the local area by 1-3Z this evening
with dry conditions overnight. Winds will become light and
variable overnight before becoming SW-SSW and increasing to around
5 KT once again by mid morning Tuesday.
