.SHORT TERM...
(Rest of today through Friday)
Issued at 235 PM EDT Thu Jun 18 2026

The upper level pattern today will continue to be dominated by
high pressure out in the Atlantic We will feel the effects of it
most today as it briefly moves westward. This shows in the PoP
forecast, with only isolated showers and storms expected today for
interior areas away from the coasts. Any isolated storms that do
develop will likely be driven by the seabreeze boundary as it
moves inland through the afternoon. Similar to yesterday, given
the weak layer of Saharan Dust causing middle level dryness an
isolated strong storm or two with gusty winds is possible.

Into Friday, as the remnants of Arthur eject eastward a shortwave
kicks across the state. This brings PoPs back up into the
scattered range by the afternoon ~45-55% inland and ~20% closer
to the coasts. More convection will be associated with the sea
breeze and any remnant outflow boundaries. The strongest storms
may bring gusty winds and localized areas of flooding.

In terms of the heat, a Heat Advisory remains in effect through
7PM today with Heat Indices ranging from 105-110F. Additionally,
Heat Risk is major (level 3 out of 4) across much of the metro
area. Many of the same conditions are expected tomorrow giving the
likelihood of a Heat Advisory being issued during the next
forecast cycle for tomorrow.

.LONG TERM...
(Friday night through next Wednesday)
Issued at 235 PM EDT Thu Jun 18 2026

The long term period looks to start off fairly active with broad
troughing dominating the upper levels for the majority of the
east coast. Additional shortwave disturbances move through on
Saturday and Sunday. This brings PoPs up into the 70-80% range
for a good portioned of the area in the afternoons both Saturday
and Sunday. The sea breeze and any outflow boundary collisions
will drive additional convection. Through the middle of the long
term period, we will see a decrease in rain and storm chances once
again as a thicker Saharan Air Layer moves into the region. PoPs
fall back into the 30-40% range during this timeframe. Most
convection will be more focused on inland areas as the sea breeze
moves in during the afternoon hours each day.

The heat won`t be going anywhere in the long term period.
Afternoon high temperatures will continue to reach the low to mid
90s each day with overnight lows in the mid 70s inland and upper
70s to lower 80s closer to the coast. Heat Risk continues to show
major (level 3 out of 4) most days along with Heat Indices into
the 105-110F range each day. Any showers and storms that develop
may bring brief relief from the heat at times.

.AVIATION...
(00Z TAFS)
Issued at 723 PM EDT Thu Jun 18 2026

Light and variable winds forecast overnight with VFR conditions at
most terminals outside of vis restrictions near the ongoing
wildfire activity in western Miami Dade. Winds will enhance and
veer onshore along both the east (SErly) and gulf (SW/Wrly) by
16-19z with the potential of inland SHRA/TSRA developing across
inland areas 19-23z. Confidence remains low on SHRA/TSRA activity
making it back to most terminals but guidance hints at potential
erratic wind shift at terminals associated with outflow
boundaries. Future TAF forecasts will refine the wind forecast at
the end of the TAF period.

.MARINE...
Issued at 235 PM EDT Thu Jun 18 2026

Gentle to moderate winds across the local waters will continue
southeasterly for the Atlantic today and southerly for the Gulf.
Isolated thunderstorms are possible across the local waters each day
with locally hazardous winds and seas possible with any storms. Seas
are expected at 1-2 feet or less outside of any thunderstorm
activity.

&&

.FIRE WEATHER...
Issued at 235 PM EDT Thu Jun 18 2026

Winds will continue to shift more southeasterly across Southeast
Florida this afternoon but remain south to southwesterly across
Southwest Florida. Isolated showers and thunderstorms are expected
to develop in the late afternoon and evening with a focus for inland
locations across the interior, including Alligator Alley and Big
Cypress. Dispersions will be generally good today and again
tomorrow. RH values will remain well above critical values.
