.KEY MESSAGES...
Updated at 100 PM EDT Mon Sep 7 2026

 - An active weather pattern remains in place into early this week
   as scattered to numerous showers and thunderstorms will
   develop each day. The strongest storms could contain heavy
   downpours and frequent lightning.

 - Heavy downpours with high rainfall rates combined with slow
   moving storms will increase the risk for localized flooding
   especially over the urban and poor drainage areas.

 - High temperatures will generally rise into the lower 90s across
   most of South Florida through this week, creating widespread
   Moderate HeatRisk.

.SHORT TERM...
(Today through Tuesday)
Issued at 352 AM EDT Mon Sep 7 2026

Upper-level troughing draped across the Eastern Seaboard will begin
lifting away into the Atlantic today, while an upper-level ridge
over central CONUS builds eastward. At the surface, South Florida
remains situated between split high pressure anchored over the
Atlantic and the Gulf. Meanwhile, a surface frontal boundary
continuing its southward push across the Southeast U.S. will help
maintain a light south-southwesterly steering flow across our region
today. With limited synoptic support aloft, convective activity will
once again be driven by sea-breeze and mesoscale boundary collisions
today.

Satellite-derived products, along with the 00Z MFL sounding and
recent ACARS data, show a pocket of relatively drier air from the
Gulf has filtered across the region, resulting in slightly
reduced PWATs compared to previous days (1.8-2.1 inches). Despite
this modest decrease, tropical moisture continuing to pool in from
the south will support an increase in convective coverage today
compared to yesterday. Under the prevailing southwesterly flow,
scattered showers and thunderstorms should develop across the
local waters and SW Florida this morning before gradually shifting
toward the East Coast, where coverage is expected to maximize
during the afternoon and early evening. Primary hazards will be
frequent lightning, gusty winds, and localized heavy downpours,
which could lead to nuisance flooding across urban and poor-
drainage areas. Given the potential for relatively drier air
lingering aloft, isolated robust thunderstorms may also produce
locally damaging downbursts.

The surface frontal boundary is expected to remain stalled out
across northern Florida through Tuesday, while the western Atlantic
high pressure pushes back into the region, shifting local winds to
the southeast. With PWATs expected to increase again to over 2
inches, scattered to numerous showers and thunderstorms are expected
to develop across South Florida on Tuesday. Under the returning
easterly flow regime, convection should initiate near the East Coast
and gradually shift inland toward the interior and SW Florida into
the afternoon.

High temperatures will generally rise into the lower 90s across the
region today, with mid 90s possible across interior SW Florida on
Tuesday. Overnight lows will remain in the upper 70s along the
coasts and low/mid 70s inland. Maximum heat indices between 103-107
degrees are expected, with Moderate HeatRisk continuing across all
urban corridors through the period.

.LONG TERM...
(Tuesday night through Sunday)
Issued at 352 AM EDT Mon Sep 7 2026

Central CONUS upper-level ridging will continue to build eastward
toward the East Coast through midweek, while the stalled surface
frontal boundary over northern Florida gradually washes out. High
pressure over the western Atlantic is expected to re-establish full
control over the region by Wednesday. PWATs and convective coverage
will lower back toward seasonal normals. Convection will remain
primarily sea-breeze and mesoscale driven, with morning showers and
isolated thunderstorms moving onshore along the East Coast before
shifting inland and toward SW Florida during the afternoon and early
evening.

Another mid/upper-level trough and associated surface frontal
boundary are expected to dig south along the Eastern Seaboard by the
end of the week, nudging the western Atlantic ridge axis southward
once again. Meanwhile, guidance also indicates a plume of Saharan
dust could overspread the region sometime this weekend. Confidence
remains low regarding the timing and impact of these features on
local weather.

High temperatures will rise into the lower 90s across most areas
through the weekend, reaching the mid 90s over interior SW Florida.
Overnight lows will range from the upper 70s/lower 80s along the
coasts to the low/mid 70s over the interior. NBM probabilities of
heat indices exceeding 105 degrees generally increase toward the
second half of the week, along with increasing probabilities of
Major HeatRisk probabilities across urban areas of South Florida.

.AVIATION...
(18Z TAFS)
Issued at 100 PM EDT Mon Sep 7 2026

Scattered SHRA/TSRA is beginning to develop across the region and
is expected to cause periods of MVFR/IFR across the east coast
terminals later today. Primary time frame to monitor for impacts
is between 19-00Z. Winds will be ESE around 5-10 kts with variable
winds expected during storms, and brief wind shifts are possible
due to outflows. At KAPF, SW winds are expected around 5-10 kts.

&&

.MARINE...
Issued at 352 AM EDT Mon Sep 7 2026

Light to gentle south-southwesterly winds will prevail today before
shifting southeasterly into midweek. Afternoon sea breezes will
produce localized wind shifts each day, turning winds southeasterly
over the Atlantic waters today and southwesterly over the Gulf
waters later in the period. Scattered to numerous showers and
thunderstorms will develop over the local waters each day. Gusty and
erratic winds, along with brief periods of rough seas, will be
possible in and around thunderstorms. Seas across the Atlantic and
Gulf waters will generally remain at 2 feet or less through the
early portion of the week.
