KEY MESSAGES

Issued at 140 AM EDT Fri Jun 12 2026

- Higher coverage of afternoon and evening showers and storms will persist into next week. Main threats will be lightning strikes, gusty winds 40-50 mph, and locally heavy rainfall from slow moving storms.

- Hot and humid conditions will lead to heat indices 100-107 and a Moderate to locally Major HeatRisk over Central Florida, residents and visitors should remain well-hydrated and seek breaks in the shade or A/C during the heat of the day. For more info about HeatRisk and heat safety tips, visit Heat.gov.

- A moderate risk of life-threatening rip currents persists at all Atlantic beaches of Central Florida. Please swim near a lifeguard.

DISCUSSION

Issued at 140 AM EDT Fri Jun 12 2026

Today-Tonight...A weak surface ridge axis stretches across south Florida today from the western Atlantic. This will lead to the beginning of a pattern change, with light offshore flow developing over the area. However, will still see a SE sea breeze develop at the coast in the afternoon, which drifts towards Orlando into the evening, increasing winds to around 10 mph. The east coast breeze is forecast to collide with the west coast breeze over the interior after around 5 PM, spurring PoPs 60-70%. Higher PoPs (40-70%) are forecast area- wide, though, as convection begins along the sea breeze in the morning near the coast, before moving inland. Warm 500 mb temperatures near -6 C are not supportive of stronger storms. But, steep low level lapse rates and precip loaded downdrafts could lead to a few stronger wind gusts 40-50 mph. In addition, locally heavy rainfall will be possible, with slow storm motions causing cells to linger over an area.

Convection will linger along the sea breeze collision into the evening hours, with slow drift back towards the coast possible, though steering flow is light. Drier conditions are expected by around midnight, which then continue into Saturday morning. Hot temperatures in the lower to mid-90s, combined with humid conditions, will produce heat indices near 100 this afternoon. A Moderate HeatRisk will be present across much of the forecast area. Residents and visitors should use caution during the heat of the day and know the signs of heat stress and heat illness. Overnight lows in the 70s will provide little relief.

Saturday-Friday...Low and mid-level high pressure linger over the Florida peninsula through mid-week next week, fending off any approaching troughs. With the ridge axis remaining south of the warning area, offshore flow will continue, strengthening next week as the pressure gradient tightens.

This flow regime, combined with PWATs near 2", will support higher, summertime PoPs through the period over the local area. PoPs up to 60-70% each afternoon will be highest along the sea breeze collision, with the morning hours remaining mostly dry. As southwesterly flow strengthens, the east coast sea breeze will still develop, but become increasingly opposed and pinned to the coastal counties. Slow moving storms and outflow driven propagation will allow showers and storms to linger into the evening hours each day, drifting offshore at times. A few strong storms will remain possible and multiple rounds of heavy rainfall due to thunderstorms could increase flooding concerns, should it occur over the same areas multiple days in a row.

Southwesterly flow will also lead to near to slightly above normal high temperatures in the lower to mid-90s. Hot and humid conditions will linger over the area, leading to increasing heat concerns. Moderate to Major HeatRisk will expand through the area, especially north of Brevard County, including the Orlando Metro. Overnight low temperatures in the mid to upper 70s for many areas will continue muggy conditions through the early morning hours. For more info about HeatRisk and heat safety tips, visit Heat.gov.

MARINE

Issued at 140 AM EDT Fri Jun 12 2026

Generally favorable boating conditions are forecast through the period, as high pressure lingers over the local waters. Increasingly offshore flow will back S/SE in the afternoons at the coast as the sea breeze develops. Winds remain around 15 kts or less, though could see 15-20 kts develop well offshore Tuesday, as the pressure gradient tightens. Seas 1-3 ft. Higher coverage of showers and storms is forecast near the coast this weekend and into next week. Convection will increasingly drift offshore in the late afternoons and evenings, as SW flow strengthens. Boaters should use caution later in the day and watch the western sky for approaching storms.

AVIATION

(12Z TAFs) Issued at 722 AM EDT Fri Jun 12 2026

Light and variable winds persist until the development of the east coast sea breeze this afternoon. Winds become more southeasterly after 17Z along the coast and after 20Z across the interior as the sea breeze moves inland. Increasing coverage of VCSH and VCTS is forecast along the sea breeze and later, along the sea breeze collision. Continued to leave out TEMPOs for now with the highest coverage potentially favored south of the interior terminals. Will continue to monitor and amend as needed. Winds are forecast to become light and variable once again beyond 00Z, with showers and storms diminishing between 00-03Z.
