Issued at 924pm EDT Sunday Jun 28 2026

Convection has ended across the area with less coverage this afternoon than yesterday. Clouds will dissipate overnight with the winds already light and variable in most locations. Current forecast is on track and have no updates planned.

Issued at 255pm EDT Sunday Jun 28 2026

Ridging continues over the area at the surface and aloft over the area this afternoon supporting another round of sea breeze convection through this evening. Showers and storms again likely to focus over areas from SWFL through W FL along sea breeze and outflow boundary collisions, with highest chances likely from around the I-4 corridor southward later this afternoon as the WC/ECFL sea breeze converge. This morning's TBW sounding continued to indicate near-average PWATs (Precipitable Waters) and relatively light winds throughout the column, and along with regional ACARS soundings indicate an increased easterly component in the SFC-3km layer winds. Therefore, while storm motions will continue to be rather slow today, the overall axis of highest Probability of Precipitation may shift slightly westward over SW/WCFL compared to yesterday. Stronger convection will continue to pose an isolated hail or damaging wind gust threat but overall severe threat remains limited. Highs in the upper 80s/lower 90s coastal and lower/mid 90s inland.

Pattern aloft over the U.S. continues to amplify, with strong high pressure becoming established over the E U.S. centered north of the local area and persisting through the week. The surface ridge shifts south across the area as a frontal boundary sinks south across the E U.S. and stalls over the Srn E Seaboard/N Gulf coast into mid week. Boundary layer flow gradually shifts to W/NW on Monday then gradually veers to E/NE through Wednesday, with daily scattered to numerous showers and storms locally. Highest rain chances shift from northern/central areas on Mon-Tuesday to central and southern areas from Wednesday onward as light and generally easterly deep layer flow becomes established over the area. Afternoon highs continue to range from the upper 80s to mid 90s, with max heat indices in the lower/mid 100s.

No major changes for the update as forecast on track. No headlines expected through the period with winds generally 10kts or less. Rain chances will increase Tuesday through Thursday as a boundary settles across the state causing localized higher winds and seas.
