KEY MESSAGES

Updated at 410 AM EDT Wed Jul 15 2026

- Heat indices between 105-109 possible today from late morning to the early evening hours. Take appropriate precautions during extended periods outdoors.

- Isolated to scattered showers and thunderstorms expected today favoring interior and western areas of South Florida. - Some of the storms may become strong to marginally severe especially across the Lake Okeechobee region. The strongest storms could have wind gusts up to 60 mph, heavy downpours, and small hail.

SHORT TERM

(Today through Thursday) Issued at 410 AM EDT Wed Jul 15 2026

Guidance consensus show a drier day today with GFS being the more aggressive solution in terms of decreasing POPs across SoFlo. The brunt of the SAL should begin moving into the area today and drive chances of rain into the 20-40% range. NAM pushes sea breezes inland early this afternoon, which should help in keeping coastal areas drier than interior SoFlo. SPC keeps the risk category for SoFlo as regular thunderstorms today, but as in the previous two days, guidance still suggests some DCAPE around 1K j/kg, along with lingering PWATs in the 1.4-1.8" range. which among other factors may be enough for scattered showers and a few strong storms, mainly inland and western SoFlo later this afternoon and evening.

Heat-related impacts also continue today with heat index values again close to or at advisory levels. This will be more likely over areas where convective activity becomes further suppressed, with Heat Index forecast for today showing possible max values in the 105- 109F range. A Heat Advisory is in effect from 11AM to 7PM EDT, focusing on coastal metro areas and portions of interior Collier county. People should avoid risking heat illness impacts by remaining hydrated and in cool locations, especially during the afternoon peak hours.

For Thursday, conditions should result in the driest day so far as the SAL remains over the region. POPs/Wx coverage drops to 10% or less for much of SoFlo with single digits for the coastal areas. With less cloud cover and shower activity, temperatures will hit the mid-upper 90s, and even approach 100 over interior Collier county.

LONG TERM

(Thursday night through Tuesday) Issued at 410 AM EDT Wed Jul 15 2026

Models show overall high pressure dominating the region, with the west Atl mid-lvl ridge extending into the SE CONUS and a sfc ridge just E of the area. Prevailing weak pressure gradients will result in generally light to moderate winds through Friday, with sea breezes developing and push inland each afternoon. The SAL should linger over the area through Friday. However, latest long range solutions are hinting at an earlier recovery of the airmass as a trough develops across the E CONUS and weakening the high pressure by Friday. This also helps in enhancing a little the overall southerly flow Friday afternoon, resulting in moisture filtering into SoFlo and POPs/Wx jumping back into the 40-60% range.

The overall synoptic scenario won't change much through early next week, with Saturday so far being the day with the highest moisture intrusion. Latest NBM came with up to 70% POPs/scattered to numerous thunderstorms for interior and eastern SoFlo Saturday afternoon. Sea breezes should develop each day and drive the development of deeper convection.

In terms of temperatures, highs through the long term will hit the mid-upper 90s each day. Heat advisory potential will be explored each day. Limit strenuous outdoor activities and take action when you see symptoms of heat exhaustion and heat stroke.

AVIATION

(06Z TAFS) Issued at 215 AM EDT Wed Jul 15 2026

VFR prevails at all terminals throughout the forecast period, with periods of VCSH this afternoon around the terminals. Winds will remain light and variable across all terminals through around 15- 16Z. At KAPF, winds should shift to the WSW around 10kt by 16-17Z as the Gulf breeze moves inland.

MARINE

Issued at 410 AM EDT Wed Jul 15 2026

A moderate southeasterly breeze will continue across most of the local waters through the end of the work week. The exception to this will be across the Gulf waters where winds will become west southwest each afternoon as the Gulf breeze develops. Scattered showers and thunderstorms will be possible across the local waters each day.
