      early next week, and could result in localized flooding and

    - Temperatures will remain above normal through the weekend.
      However, a frontal passage Monday-Tuesday could bring much
      cooler temperatures mid week.

.SHORT TERM...
(Rest of today through Monday)
Issued at 114 PM EDT Sun Mar 15 2026

Radar and satellite data has shown increasing thunderstorm
activity through the late morning hours, with bands of showers and
embedded thunder drifting northward from the Fl Keys and into
Miami-Dade. Stronger cells are likely to develop at any moment
during the rest of the afternoon hours as the convective bands
continue to gradually push northward. The best pool of moisture
and steeper lapse rates resides around central/eastern Broward and
Palm Beach counties, so these areas should experience the next
round of strong storms this afternoon.

Data from latest model soundings and KEY upper air sounding show
500mb temps around -11C, along with a very wet vertical profile
through 9km. PWATs are now in the 1.5-1.8" range, remaining above
March normals, along with effshear around 20kt and adequate DCAPE.
This synoptic scenario should continue to support widespread rain
and numerous thunderstorms for the rest of today and possibly into
the evening hours ahead of an approaching cold front from the NW.

The wet and unsettled weather conditions may continue on Monday with
potential for periods of heavy rain resulting in localized flooding.
The risk of severe weather will decrease Monday afternoon as latest
SPC outlook places highest risk on Day 2 just north of SoFlo with
only Palm Beach remaining in the Marginal level. But thunderstorm
activity is likely again tomorrow afternoon, and can`t rule out
having a few strong to severe storms developing at times.

Main hazards concerns associated with the strongest storms are
potential for damaging wind gusts, large hail and localized
flooding, especially over east coast metro areas prone to urban
flooding.

Guidance show fair agreement between solutions about the arrival
of the front late Monday, keeping POPs/Wx coverage in the 60-70
percent range across much of SoFlo through the late night hours
Monday.

High temperatures today should still hit the low-mid 80s despite the
increased cloud cover. Overnight lows will remain in the low 70s
along the coast, and mid 60s over the interior. Temperatures on
Monday will reach the mid to upper 80s.

.LONG TERM...
(Monday night through Saturday)
Issued at 215 AM EDT Sun Mar 15 2026

The aforementioned strong synoptic complex (consisting of a deep
upper level trough and stout surface low and cold front) will
continue to progress eastward Monday night, pushing the cold front
across our area overnight into Tuesday. This frontal passage will
continue to support scattered convective activity Monday night, with
the continued potential for a marginal severe weather threat. A
cooler airmass will move in behind the front, with temperatures
dropping to the low 70s during the day Tuesday and Wednesday, and
down to the 40s and 50s. Winds will also surge behind the front,
with breezy conditions expected mid week.

Models show the aforementioned front will linger over the western
Caribbean waters, helping focus enough moisture and instability in
our near vicinity to promote convective activity over our local
waters and perhaps even over the East Coast each afternoon.
Additionally, guidance is also showing a potential cut-off low break
off from weak troughing aloft and drifting over our area late this
week, with a surface trough or area of low pressure developing near
the surface. This could help increase chances of scattered showers
and thunderstorms Thursday and Friday afternoon, especially across
the East Coast metro area.

(00Z TAFS)
Issued at 650 PM EDT Sun Mar 15 2026

Brief MVFR cigs/vis periods still possible with lingering showers
around the Atl terminals through 01-02Z. VCSH may also linger
through the nighttime hours. SE winds around 10 kts continue
through around 12Z, then winds begin shifting more southerly and
becoming gusty. Another round of showers and thunderstorms may
bring periods of restrictions Monday afternoon and evening.

&&

.MARINE...
Issued at 215 AM EDT Sun Mar 15 2026

A moderate to fresh southerly to southeasterly breeze will prevail
across all local waters through Monday ahead of a frontal approach
late Monday into Tuesday. Winds will increase out of the north
behind the front mid-week, potentially resulting in hazardous
boating conditions. Seas will remain  below 3 feet across the Gulf
waters, and between 3-5 feet across the Atlantic waters. Scattered
to numerous showers will be possible across all local waters this
afternoon and early next week, with potentially rough seas and
strong winds near any storms.

.BEACHES...
Issued at 215 AM EDT Sun Mar 15 2026

Palm Beach and Broward county beaches will be at high risk of rip
currents today as northerly swell persists.
