KEY MESSAGES

Updated at 101 AM EDT Sat Aug 15 2026 - Heat Advisory for all of South FL today. Heat will remain a concern through the next week.

- A moderate risk of rip currents is expected today along the east coast beaches.

SHORT TERM

(Today through Sunday) Issued at 101 AM EDT Sat Aug 15 2026

This weekend will feature surface high pressure over the northern Gulf and another high over the western Atlantic. At the upper levels, strong ridging centered over the deep South US will remain in control. A upper level low will pass well to our south today. Convection today will be primarily sea-breeze driven, with the highest PoPs focused over inland and SW FL this afternoon into early evening. High temps will be in the low to middle 90s. Combined with dewpoints in the mid to upper 70s, peak heat indices will again top out in the 105 to 110 range. A heat advisory will be in effect from 11 AM this morning until 7 PM this evening. Convection wanes around sunset this evening, with mostly dry and warm conditions overnight. Low temps will be in the middle 70s to lower 80s.

On Sunday, higher concentrations of Saharan dust are expected to move into South FL. Forecast soundings show much drier air, with PWAT values falling to around 1.3 inches. Outside of a few mid to late day thunderstorms over the interior and around the lake region, most of South FL will be dry and hot. High temps will be in the low to mid 90s across the metro, and upper 90s over interior South FL. Peak heat indices will approach advisory criteria again, so additional headlines may be needed.

LONG TERM

(Sunday night through Friday) Issued at 101 AM EDT Sat Aug 15 2026

Saharan dust will continue to linger through the early part of next week, which will continue to keep PoPs well below average through at least Wednesday. As dust concentrations decrease across the area late in the week, low level moisture is expected to increase and PoPs will rebound to closer to seasonal norms.

Heat will continue to be a major story next week, with above average temps expected to continue. High temps each day will range from the low to mid 90s across the metro, to upper 90s over interior South FL. Peat heat indices each day will approach or exceed advisory criteria.

AVIATION

Issued at 101 AM EDT Sat Aug 15 2026

Moderate east to southeast flow will result in an elevated risk of rip currents today for the Atlantic beaches. The rip threat is expected to decrease on Sunday.
