KEY MESSAGES

- While drier air aloft will limit thunderstorm chances and rain totals each day this week, the potential for strong wind gusts is higher in thunderstorms that do form. Have multiple ways to receive weather alerts.

- Temperatures will run slightly above normal, with afternoon max temperatures in the mid 90s over the interior and around the low 90s near the coast. There is a Moderate to Extreme HeatRisk in response; be sure to practice good heat safety if spending prolonged periods outside.

DISCUSSION

Issued at 155 PM EDT Mon Aug 10 2026

High pressure is dominant across the region today, with a sprawling upper-level ridge axis directly overhead while the subtropical ridge axis is centered just to the east of the Florida peninsula. In response to the nearly vertically stacked nature, there is an ESE flow present, but it is extremely light near the surface. Thus, sea breeze boundaries along the Florida West Coast are beginning to develop, making some slow progress inland.

The west coast sea breeze boundaries are likely to be the main focal point for convective initiation this afternoon across West Central and SWFL. The afternoon ACARS soundings continue to show PWATS between 1.5 and 1.6 inches - which remains sufficient to support some convection, but only in areas with the greatest moisture pooling. This is most likely to take place in the vicinity of the sea breeze boundary, with perhaps a couple colliding outflow boundaries also being able to support a couple additional storms as well.

Overall, though, dry air means most will stay warm and dry today. This has allowed heat indices to creep up to near Heat Advisory criteria; but afternoon mixing of that drier air downward should help lower dewpoints just enough to prevent widespread 108 degree heat indices from occurring. This will continue to be the case into tomorrow as well.

Looking beyond at the next several days, the pattern remains very static. The ridge axis will remain across the region, with a light and variable flow dominant (perhaps slightly ESE). Drier air also sticks around as well, keeping rain chances lower than normal at least until the end of the week when moisture gradually increases again. Thus, heat will remain a potential impact as many students start back to school this week.

AVIATION

(18Z TAFS) Issued at 155 PM EDT Mon Aug 10 2026

There is still a low probability (30% chance or less) for thunderstorms to impact coastal terminals this afternoon and evening, with lower chances across the interior. If thunderstorms do form, there will also continue to be a higher chance for microbursts with drier air aloft. However, this drier will keep the overall potential for thunderstorm impacts lower for most of the week, with the windows for thunderstorms to develop generally shorter as well. There are no other significant aviation concerns at this time.

MARINE

Issued at 155 PM EDT Mon Aug 10 2026

High pressure east of Florida will keep southeast flow in place, with winds turning onshore near the coast in the afternoon each day as the sea breeze develops. While drier air has settled across the region, some thunderstorms are still expected this afternoon. These thunderstorms will develop over land and will move offshore late in the day and into the evening, producing strong, gusty winds and locally hazardous seas in the vicinity. Outside of thunderstorms, winds will generally remain less than 15 knots. Tuesday through the rest of the week, the ridge will shift west into the eastern Gulf, bringing in drier air aloft with lower rain chances.

FIRE WEATHER

Issued at 155 PM EDT Mon Aug 10 2026

While drier air will lower the overall rain chances (and potentially lead to the overall fire danger creeping up in areas that do not see rain), ample moisture will keep RH values high while a ridge of high pressure aloft will keep winds light. As such, there are no significant red flag concerns through the week.
