.AVIATION... (12Z TAFS) Issued at 850 AM EDT Wed Oct 8 2025
VFR conditions should prevail through the TAF forecast period, but isolated to scattered showers and thunderstorms could potentially cause some brief MVFR/local IFR conditions at the southwest Florida TAF sites of PGD, FMY, and RSW. Also, late tonight into early Thursday morning there is a possibility of some MVFR ceilings around the Tampa Bay and I-4 corridor. East to northeast winds will increase to around 10 knots with some higher gusts this morning and continue into this evening before diminishing to 4 to 7 knots late this evening into early Thursday morning.

.DISCUSSION... Large upper ridging extends from the W Gulf over the N FL Peninsula and into the W Atlantic. Mid to upper level drying continues to expand from N FL over the area through C FL as seen in WV imagery, FL soundings and ACARs data. Some deeper moisture remains over S FL to keep rain chances for mainly low topped showers SW and S FL locations this afternoon and Thursday. Temps will continue to remain above climate normals into the 90s with dew points in the 70s to produce a limited heat risk during afternoon hours.
A shortwave trough will dig into the SE US Thursday deepen and meander overhead through the weekend and into early next week bringing a pattern chance to the region. A cold front is expected move into Florida Friday then exit S FL Saturday with a chance of showers or a few storms ahead of and along the front.
High pressure building into the region will bring a slightly cooler and drier airmass to the area this weekend for FL fall like conditions. Low temperatures drop into the low to mid 60s and highs will be in the low to mid 80s into next week.
&&
.MARINE... Breezy winds will produce hazardous marine conditions at times through the week and into the weekend. Moderately tight pressure gradient to keep gusty NE-Eerly winds over some coastal waters around SCEC levels through Thursday with winds around 15-20 knots and seas 3-5 feet. Gradient tightens increasing winds Friday into the weekend ahead of a cold front and a SCA may be needed for the latter part of the week and continuing through Saturday.
&&
.FIRE WEATHER... Warm temps and humid surface conditions continue with occasionaly gusty easterly winds and generally low rain chances for mainly afternoon showers. A cold front is expected to move through the region this weekend with drier conditions early next week, however RH values should remain above critical levels.
