GMZ700 Synopsis For The Suwannee River To Okaloosa-walton County Line Out To 60 Nm 215 Pm Edt Sat Oct 23 2021
Synopsis.. Easterly flow continues through Sunday night, when it could briefly reach 15 knots. Winds will veer to the southwest on Monday ahead of a cold front, then become northwest Monday night behind the front, around 10 knots. The approach of a strong area of low pressure over the tennessee valley will turn winds southerly on Wednesday, with its associated cold front moving through the waters on Thursday. Winds on both Wednesday and Thursday are expected to be solidly at advisory levels, ranging from 20 to 25 knots, with significant wave heights building to 8 feet just offshore on Thursday. There is also the potential for gale force gusts with the passage of a squall line ahead of the cold front, and then again behind the cold front.

Area Forecast Discussion National Weather Service Jacksonville FL 527 PM EDT Sat Oct 23 2021

NEAR TERM [Through Tonight].

An mid to upper level trough is moving off the east coast of the US with ridging in it's place from the Ohio Valley to the southeast region promoting a subsident airmass over our region. At the surface, high pressure will continue to build north of the area this afternoon in the wake of cold front that passed south of the area this morning with dry conditions and light NE winds around 5-10 mph. Afternoon high temperatures will be warmest over NE FL with values in the mid to upper 80s while SE GA and coastal top out in the low 80s.

Tonight, high pressure will slide east towards the Delmarva portion of the Mid Atlantic coast and light onshore flow will become easterly at the coast and calm inland west of I-95 under increasing high clouds from the Gulf of Mexico as a shortwave approaches from the SW. The NE low level flow will keep the drier airmass in place over NW parts of our area while the NE onshore flow from the Atlantic modifies temperatures at the coast.

Sunday, a progressive pattern will shift ridging aloft into the western Atlantic waters off the east coast of the U.S. as a mid to upper level trough develops from the Rockies into the central plains states. This pattern will push the surface high to our north eastward into the Atlantic waters with low level flow turning easterly with gradual veering winds aloft that will begin to restore moisture levels over our region from PWATs under 1.0 inch to PWATs in the 1.25 to 1.50 inch range. Rain chances will increase south of the area near the stalled frontal boundary over the southern FL peninsula as a inverted trough forms over the southern and central FL coastal waters. The inverted trough will move north adjacent to the FL Atlantic coast with a weak low possibly forming into Sunday evening near the Treasure coast and this feature coupled with shortwave energy passing overhead in the SW mid level flow will deliver some rain chances over NE FL by late Sunday afternoon mainly along the NE FL coast and parts of north central FL. Highs will be in the mid to upper 80s over both NE FL and SE GA.

SHORT TERM [Sunday Through Monday Night].

A weak shortwave impulse will exit north and east of the FL peninsula with showers early in the day moving off the coast by evening as a weak low/inverted trough lifts NE into the western Atlantic waters leaving moist low levels and light SW winds in it's wake with mostly cloudy skies becoming partly cloudy. Patchy fog will develop late Monday night into Tuesday morning ahead of cold front that will sag southeast into the area and stall over NE FL with no showers expected as drier air aloft moves over the region and high pressure builds well north of the region over Ontario Canada. Winds will become westerly Tuesday with mostly sunny skies and then turn northwesterly Tuesday evening .

Temperatures will be above seasonal averages on Monday with highs in the mid to upper 80s and slightly cooler over SE GA areas on Tuesday with highs closer to seasonal values in the low 80s. Lows on Tuesday morning will be about 10 degrees above seasonal averages in the mid to upper 60s and then cool to slightly below seasonal averages in to the low 50s over SE GA and the mid to upper 50s over NE FL, near 60 degrees at the SE GA coast and 60s at the NE FL coast.

LONG TERM [Tuesday Through Saturday].

Wednesday, the stalled frontal boundary over NE FL will lift northward with dry conditions and winds shifting back to the SW with increasing high clouds ahead of an amplifying mid to upper level trough swinging into the central and southern plains.

Thursday, the mid to upper level amplifying trough will move eastward with the core of the trough moving into the OH valley as the base of the trough spins southeast into our region. This will bring a strong cold front eastward across the deep south and gulf coast into our area with increasing shear and moist unstable SW flow aloft. The GFS model is still a little faster than the ECMWF model with the bulk of the showers and storms approaching the area early Thursday with activity clearing east by Thursday evening while the ECMWF is a little slower and delays showers and storms until late Thursday afternoon and evening before completely exiting into the Atlantic waters early Friday morning, creating a near 12 hour difference in timing at this juncture. For now, have placed chance of pops 30 to 50 percent for Thursday morning with likely pops 60 to 70 percent for the afternoon time frame with slight chances for storms. Potential exists for strong storm potential into late Thursday and later forecasts will refine this possibility.

Friday, breezy westerly winds and drier conditions will arrive behind the surface cold front as high pressure builds west of the region over the southern plains as an upper level low slowly passes north of the region over the southern appalachians.

Saturday, light northwest winds will bring cold air advection and clear skies as the high to the west builds over the lower MS valley.

Temperatures will be near seasonal temperatures on Wednesday and Thursday with below seasonal averages Friday into the weekend.

AVIATION. [Through 18Z Sunday]

Reader's Digest version: VFR conditions through 18Z Sunday with no issues.

More detailed discussion: High pressure dominates the surface with some CI/CS overriding the region from the Gulf with cloud bases of 200-250 KFT. Coverage FEW to SCT today and BKN tonight into Sunday. Winds generally northerly today and easterly tomorrow less than 10 knots, becoming variable less than 5 knots overnight. Generally too dry for significant fog formation overnight.

MARINE.

High pressure will build north of the waters through this evening in the wake of a cold front stalling south of the coastal waters with light northeasterly winds. The high will move northeast of the waters on Sunday with winds becoming easterly as an inverted trough lifts north along the Florida coastal waters Sunday into Sunday night with showers and a few storms developing over the waters into early Monday. The inverted trough will lift away to the northeast Monday and a weak cold front will approach from the northwest and move through the waters on Tuesday. The front will lift back north of the waters as a warm front on Wednesday before a strong cold front a stronger cold front accompanied by showers and a potential for strong thunderstorms moves through on Thursday.

Rip Currents: Moderate risk today for NE FL beaches with a low risk for SE GA beaches. A moderate risk is in effect for all area beach on Sunday.
