Marine Weather and Tide Forecast for Cedar Key, FL

SHORT TERM AND LONG TERM
(Today through next Wednesday)
Issued at 219 AM EDT Thu Apr 16 2026

Strong mid level high pressure is situated over the northeast Gulf and up the eastern seaboard while a shortwave trough is located in the southern Plains. The ridge will be shunted south this afternoon and tonight as the trough moves northeast through the Tennessee Valley. The ridge builds back northward ahead of another trough moving through the Plains and an associated cold front.

Before the front arrives Sunday, very warm temperatures will continue into the first half of the weekend. Highs will continue in the mid to upper 80s with around 90 degrees in some locations in the Florida Big Bend and southern Georgia / I-75 corridor Friday and Saturday. Along with this, fog development appears likely each morning through Saturday. HRRR/NBM probs for dense fog is around 60- 70% through the Panhandle and Big Bend where a dense fog advisory is in effect and may need to be extended east overnight tonight and may require another advisory Friday morning.

Much of the forcing with the cold front will be located well north of the area as the front swings by but may be just enough to squeeze out a few showers (holding around 20% west of the Flint/Apalachicola rivers Sunday morning). Slightly cooler and drier air will be left in the wake of the front with highs in the 70s and 80s Sunday through Tuesday then a gradual moderating trend Wednesday with more widespread 80s returning.

Fire concerns continue through the area with the ongoing drought and continued dry conditions. The next front appears to be a mostly dry frontal passage with a reinforcing shot of drier air on north to northeast winds. In fact, afternoon humidities may fall below 20% in spots Monday, which coupled with breezy winds and it sets the stage for high fire danger which may extend into Tuesday as well.
