.SHORT TERM (TDY-SUN)... Issued at 416 AM EDT Sat Sep 13 2025
Much drier conditions in place this morning across the Sunshine State. ACARS sounding showed PWAT values around an inch and a lot less clouds are present compared to the last few days. Meanwhile, upper level trough stretching along the Eastern Seaboard remains there allowing drier air to be pushed across the peninsula. A boundary stalled south of the area and enough moisture available over southern portions of the CWA will support showers and isolated storms this afternoon. Otherwise, most of us remain dry. NOrth to northeasterly winds prevail and will push any activity that does develop southward.
On Sunday, morning lows will dip into the mid 60s in portions of the Nature Coast. Drier air remains across most of the state with lower rain chances in place. High temperatures stay in the upper 80s with dewpoints dropping into the 60s along the Nature Coast.

.LONG TERM (MON-FRI)... Issued at 416 AM EDT Sat Sep 13 2025
DUring the long term, model guidance keep dry air in place as high pressure builds to the west while trough remains along the coast through mid week. Then, strong ridge pushes trough east as higher moisture filters in. This will support an increase in rain chances across the area. Temperatures stay fairly unchanged.

.AVIATION... (06Z TAFS) Issued at 205 AM EDT Sat Sep 13 2025
VFR conditions anticipated across most terminals through the period. MOde; guidance brings lowering ceilings close to sunrise, but confidence is not high enough to show a change categories at this time. North to northeasterly winds prevail and become breezy going into the afternoon, especially near PIE. Additionally, there is the potential for showers and storms to develop near southern terminals during the afternoon and evening hours.

.MARINE... Issued at 416 AM EDT Sat Sep 13 2025
Frontal boundary just south of the state will support periods of winds in the exercise caution criteria across the northern and central waters through tonight. Otherwise, they are expected to remain 10 to 15 knots out of the northeast to north winds with seas up to 3 feet. Over the weekend the boundary will drift further south as high pressure builds in from the north with some drier conditions expected, but isolated to scattered mainly late afternoon and early nighttime showers and thunderstorms will remain possible.

.FIRE WEATHER... Issued at 416 AM EDT Sat Sep 13 2025
A frontal boundary remains south of the state today. This will bring drier air across the area lowering rain chances. The highest rain chances should be over the interior and south FL. North to northeast winds prevail becoming gusty at times through the weekend. Relative humidity values will remain above critical levels during this time.
