KEY MESSAGES

Issued at 239 PM EDT Mon Aug 10 2026

- Hot and humid conditions continue the next several days. Peak heat index values will easily reach 102-107F. Potential to reach Heat Advisory criteria (108-110F) will exist for portions of the area this week.

- Near to below normal rain chances this week. The drier air aloft will support strong gusty winds in storms each day.

DISCUSSION

Issued at 239 PM EDT Mon Aug 10 2026

Thru tonight...Upper air sounding from XMR this morning showed noticeably drier air through the column with PWAT down to 1.8" with the bulk of that moisture below 900 mb. Atlc sea breeze is pushing inland sparking isolated showers and some of these will develop into lightning storms over the interior as boundary collisions increase. The drier air aloft is producing high DCAPE values over 1100 J/kg so any deep convection will be capable of gusty winds up to 50 mph but coverage looks limited (~30%). Convection will wind down over the far interior by 10 pm.

Tue-Sun...High pressure ridge aloft moves in and holds across the area. The assocd suppression/subsidence as well as another plume of Saharan air will contribute to dry mid levels and below normal storm chances. While skies may become more hazy this week due to the Saharan dust, the particulates are suspended mostly aloft and do not typically cause air quality issues at the sfc here in central FL. There is a gradual rise in rain chances Thu-Fri as moisture/convergence pools on the north side of the low level ridge axis. Then drier air moves back in this weekend and limits rain chances, especially Sunday. Any storms that do manage to form will have the potential to become strong, producing strong wind gusts of 40-50 mph and frequent lightning strikes. Weak steering winds will also allow for heavy downpours from some storms, producing locally heavy rainfall of 1-2" each day.

These drier than normal conditions will allow for rising heat impacts through the week as little relief will be found from afternoon convection. Max temps will reach the low to mid 90s each day. Peak heat index values will easily reach 102-107F, and will have to monitor the need for additional Heat Advisories as portions of the area should see heat index values rise to 108-110F. Warm and muggy overnight temps in the mid to upper 70s will also amplify the overall heat impacts, with widespread Moderate to Major HeatRisk forecast for much of the area each day. Continuing to follow heat safety practices will remain important as we go through the week.

MARINE

Issued at 239 PM EDT Mon Aug 10 2026

Favorable boating conditions are forecast to continue this week. The Atlantic ridge axis north of the area will settle south across the local Atlc waters tonight and Tue and then reach south FL Wed. SE winds will become S/SW Tue and W/SW by Wed-Thu. However, the offshore flow will remain weak enough for the east coast sea breeze to still form each afternoon with winds becoming onshore (SE) near the coast at 10-15 knots. Seas to 1-2 feet are forecast this week. Shower and lightning storm chances will be below normal this week with coverage at 30% or less.

AVIATION

(00Z TAFs) Issued at 655 PM EDT Mon Aug 10 2026

Light and variable winds with VFR conditions anticipated through the overnight hours. Winds pick up out of the SW across the interior after 14Z and out of the ESE along the coast after 16Z. As the ECSB develops and moves inland, VCSH will be possible, with chances starting at 16Z along the coast and 19Z across the interior. Anticipate the pattern being similar to how conditions panned out today, so too low confidence to include VCTS mention at this time. A return of lighter winds and dry conditions are anticipated after 20Z along the coast and after 00Z tomorrow across the interior.
