KEY MESSAGES

Issued at 257 PM EDT Mon Jun 15 2026

- Scattered to locally numerous afternoon and evening showers, as well as lightning storms will persist through midweek with scattered coverage into late week. There is the potential for a few strong storms each day, which will have the capability of producing frequent lightning strikes, wind gusts up to 40-50 mph, and heavy rainfall with slow-moving storms.

- Hot and humid conditions will lead to heat indices generally between 100-107 with a Moderate to Major HeatRisk. 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 central Florida Atlantic beaches. Always swim near a lifeguard and never enter the water alone!

DISCUSSION

Issued at 257 PM EDT Mon Jun 15 2026

Current-Tonight... A cold front is analyzed along the eastern U.S. seaboard, stretching through the southeast U.S. this afternoon. The front is forecast to remain nearly stationary and north of the local area as high pressure works to hold control of east central Florida. Deep moisture persists over the Florida peninsula with GOES-19 PWAT imagery indicating values (1.9-2.1") within the 90th climatological percentile. This should continue to promote a persistent pattern of scattered to locally numerous showers and storms this afternoon and evening. The first initiation of storms has occurred along a boundary stretching across northeast Florida and into Lake and Volusia counties, and westerly flow will continue to push convection offshore. Otherwise, we're continuing to monitor for additional development of showers and storms along the coast as the sea breeze struggles to form this afternoon and evening. Primary storm hazards include frequent lightning strikes, wind gusts up to 50 mph, and periods of locally heavy rainfall. Cannot rule out a brief funnel cloud or waterspout along boundary collisions with prevailing offshore flow. Any convection should diminish a few hours after sunset with dry conditions expected overnight. Warm and muggy tonight with most locations seeing low temperatures in the mid to upper 70s.

Tuesday-Wenesday... High pressure continues to control the local weather pattern. A flattened ridge axis aloft will hold south of the area into mid week, stretched across the western carribean islands. At the surface, a ridge axis remains near the Florida Straits and south Florida. Despite some model discrepancies in total moisture, near or above climatological PWATs should continue to support a persistent pattern of scattered afternoon and evening showers and storms. Southwest flow around 5-10 mph should delay and pin the east coast sea breeze, keeping the best chance for showers and storms in vicinity of the I-95 corridor, especially on Tuesday. Westerly steering flow should additionally allow for any interior convection to push back toward the coast and offshore each evening. Tall storms which develop along boundary collisions will be capable of frequent lightning strikes, localized strong winds to 50 mph, and localized heavy rainfall accumulations of 2-3" in a 60-90 minute period. A brief spinup of a funnel cloud or waterspout cannot be ruled out.

Outside of showers and storms, heat remains the primary headline. Highs mostly in the low to mid 90s will combine with humidity to produce peak heat index values between 100-107F. A Moderate HeatRisk builds across east central Florida. A localized Major HeatRisk across portions of the Orlando Metro and Brevard on Tuesday expands to include portions of the Treasure Coast on Wednesday. Never leave children or pets unattended in a hot vehicle for any length of time! Look before you lock! For more info about HeatRisk and heat safety tips, visit Heat.gov.

Thursday-Sunday... High pressure gradually lifts northward into late week with it's axis settling near or over south Florida this weekend. A cold front sinks through the southeast U.S. stalling near north Florida this weekend, increasing local moisture late week. A hot and humid pattern continues with scattered showers and storms remaining favored over the eastern side of the peninsula each afternoon and evening. Near to above normal temperatures persist with highs in the low to mid 90s. A Moderate to Major HeatRisk will affect those without adequate cooling or hydration.

MARINE

Issued at 257 PM EDT Mon Jun 15 2026

Generally favorable boating conditions continue this week. A surface ridge axis holds near the Florida Straits through mid week before gradually lifting northward. Offshore flow remains in place. However, winds will shift south to southeast around 10-15 kts (locally 15-20 kts) each afternoon as the sea breeze develops. Seas mostly 2-3 ft. Scattered to locally numerous offshore moving storms are forecast in the afternoons and evenings, and a few stronger storms will be capable of wind gusts of 34 kts, locally building seas.

AVIATION

(18Z TAFs) Issued at 143 PM EDT Mon Jun 15 2026

Offshore/WRLY winds around 10 kts, occasionally pushing above with gusts to around 20 kts, keeping the east coast sea breeze pinned along the coast. ISO-SCT SHRA/ISO TSRA have developed INVOF KDAB, north of KLEE-KSFB, prompting TEMPOs at KDAB. While this activity is generally moving eastward/offshore, any outflow generated could propagate south and develop additional ISO-SCT TS. In the absence of this outflow, development of inland TS likely to be more gradual/ISO, with the highest coverage east of KMCO and other inland terminals. Highest coverage/chances of TS along the sea breeze collision near coast after 20Z. Made adjustments to TEMPO timing based on latest guidance. SHRA/TSRA gradually diminish after 00Z, but could persist as late as 04Z. Quiet overnight once convection clears. Winds settle to 5-10 kts from the WSW-SW overnight, then pick back up Tuesday to around 10 kts from the SW. Low chances for afternoon-evening SHRA/TSRA at inland terminals, higher along the coast.
