| Synopsis for the Suwannee River to Okaloosa-Walton County Line out to 60 nm - GMZ700 1130 AM EDT Sun Oct 25 2020 Relatively light winds and low seas are forecast through Monday. Conditions will begin to deteriorate on Tuesday as winds increase and swell from Zeta starts to reach our offshore waters. The worst marine conditions are expected Tuesday night through Wednesday night as Zeta moves towards the northern Gulf coast. Across our waters west of Cape San Blas, tropical storm conditions are possible from Wednesday into early Thursday. Cautionary conditions may prevail through the end of the week until a frontal boundary clears the northeast Gulf in the wake of Zeta. |
| Area Forecast Discussion National Weather Service Tallahassee FL 348pm EDT Sunday Oct 25 2020 .NEAR TERM [Through Monday]... Quiet conditions expected for the near term period. Biggest weather highlight through tomorrow will be areas of fog that will develop tonight. An upper level ridge moving over the region combined with light winds, mostly clear skies in the upper levels, and plenty of low level moisture is a ideal setup for fog across the region. Low temperatures tonight will generally be in the mid 60s with cooler conditions across AL and warmer conditions across the Big Bend. No rain is expected tomorrow, but as additional low level moisture moves in from the southeast, can't rule out a light shower in northeastern parts of the forecast area in southern GA. .SHORT TERM [Monday Night Through Tuesday Night]... As an upper-level ridge remains just offshore from the Florida Atlantic Coastline, we should continue to see suppressed convection for the majority of our CWA in the short term. However, towards to later part of the short term period we may begin to see precipitation chances gradually increasing depending on Tropical Storm Zeta's track with the greatest chances being offshore. Since our region will be on the eastern side of Zeta, we can expect a plume of moisture being advected into the region, hence the increasing PoPs. Expect highs to be in the mid 80s and lows to be in the mid to high 60s for most of the region, areas near the Gulf Coast will be hovering around 70. Long Term - Wednesday Through Sunday There is a great deal of uncertainty associated with the track of Tropical Storm Zeta, current model guidance has Zeta making landfall around southeastern Louisiana. With the ridge positioned over the western Atlantic and an approaching trough crossing through the central plains, large-scale steering currents should have Zeta increasing in forward speed as it crosses through the Gulf of Mexico. This should prevent Zeta from producing prolonged impacts as it rushes past the Gulf Coast. Cooler waters near the coast, along with upper-level shear should help weaken/prevent further strengthening as it approaches the US. Although our region isn't currently near the center of the forecast track, we will still experience peripheral impacts via banding. The greatest chance for precipitation currently resides between Wednesday and Thursday. After Zeta gets absorbed by the trough and the associated frontal system moves through the area Thursday night, we should expect drier and cooler weather through the end of the period. Marine Relatively light winds and low seas are forecast through Monday. Conditions will begin to deteriorate on Tuesday as winds increase and swell from Zeta starts to reach our offshore waters. The worst marine conditions are expected Tuesday night through Wednesday night as Zeta moves towards the northern Gulf coast. Across our waters west of Cape San Blas, tropical storm conditions are possible from Wednesday into early Thursday. Cautionary conditions may prevail through the end of the week until a frontal boundary clears the northeast Gulf in the wake of Zeta. Fire Weather Red flag conditions are not expected for the next several days. Hydrology As we approach mid-week rain chances increase once Zeta gets absorbed into a frontal system and moves through the Southeast. Due to the expected progressive nature of the system, average rain amounts are currently forecast to be around 1-3" and focused primarily west of the Flint/Apalachicola basins. These amounts are not forecast to bring with them a widespread river or flash flooding concern. However, the eventual track and intensity of Zeta could alter this outlook as we draw nearer to the event. NOAA Tallahassee FL Office: Watches - Warnings - Advisories FL...None. GA...None. AL...None.
