Synopsis.. A slow moving front will continue to edge south across the local waters today. A weak area of low pressure will form offshore of the florida atlantic coast tonight, with an increase in onshore winds briefly Sunday morning before the front across central florida lifts back north across the area as a warm front into Sunday evening. A strong cold front will cross the waters Monday trialed by stronger offshore flow and building seas to near advisory levels late Monday into Tuesday. Winds and seas decrease late Tuesday into Wednesday as high pressure across the gulf coast states builds east across the local waters. The approximate location of the west wall of the gulf stream as of nov 28, 2020 at 1200 utc... 56 nautical miles east of flagler beach. 68 nautical miles east of saint augustine beach. 81 nautical miles east of jacksonville beach. 91 nautical miles east southeast of st simons island.

Area Forecast Discussion National Weather Service Jacksonville FL 930 AM EST Sat Nov 28 2020

. COOLER WITH WAVES OF PASSING SHOWERS TODAY .

UPDATE.

A frontal zone extended across south Georgia this morning as surface high pressure strengthened NNW of the region, shunting the boundary slowly southward. A mid level disturbance within zonal flow overrode the front this morning which led to widespread stratiform rainfall with 0.50-1.5 inches for areas along and WNW of Jesup to Homerville. Into the afternoon, stratiform rainfall will continue to break apart as the mid level disturbance moves offshore, away from the local area and the surface front edges farther south across NE FL. A cooler, drier NNE flow will develop across SE GA into the afternoon where highs will range in the 60s under mostly to partly cloudy skies, while warmer temperatures in the mid/upper 70s under partly cloudy skies will impact NE FL south of the front (generally south of the I-10 corridor).

The 12z JAX RAOB continued to show very high moisture content for this time of year (PWAT > 1.6") and elevated CAPE with surface heating into the mid 70s. Opted to include isolated t'storm in the update for our NE FL near the Gulf Coast region this afternoon, along and just south of the front where higher instability is expected.

MARINE.

West winds this morning 5-10 kts ahead of the front will transition to WNW then NNE into the afternoon 10-15 kts as the front settles across central FL and lingers. A wave of low pressure forms along the front tonight east of the FL Atlantic coast with a brief increase in NNE winds early Sun morning near 15 kts for the GA waters, but still below headline criteria at this time. Combined seas will range between 2-4 ft with passing light/mod rain showers.

Rip Currents: Low risk today.

PREV DISCUSSION [649 AM EST].

Near Term. /through Tonight/ .

For Today, frontal zone will lay west to east near the GA/FL line this morning, then slowly sink south of the forecast area this afternoon. Ample low level moisture this morning, will result in areas of fog, and low cloudiness. Patchy dense fog will be possible, especially in the frontal zone. A wave of low pressure will move east along the boundary this morning, spreading rain showers across the area, with a few embedded thunderstorms. This wave will pass east of the region later this afternoon, taking most of the shower activity with it.

High pressure will build toward the northeast Tonight, with the frontal zone stretching across central Florida, beginning to lift back north as a warm front toward Sunday morning. As this boundary begins to lift shower chances will return.

Temperatures will trend near to a little below normal across SE GA Today, but above over much of NE FL. Above normal temperatures will be the trend Tonight.

SHORT TERM [Sunday Through Monday].

On Sunday, a mid/upper level southern stream cutoff low will phase with northern stream trough diving SE from the northern plains region into the Upper midwest and develop a strengthening surface low over the lower Mississippi Valley. A warm frontal boundary over central FL will lift northward during the day and light winds will veer from the east to southeasterly at the surface with southerly flow just above the surface helping to increase atmospheric moisture levels with PWATs rising into the 1.5-1.9 inch range with southwesterly flow in the mid levels bringing shortwave energy over the region with bulk shear increasing to 45-50 knots over the area. However, the low level instability appears weak during Sunday afternoon and evening as the warm front retreats northward. If there's an increase in low level instability, the chances for strong to severe storms ahead of the cold front will become more likely, but for now have only slight chances for thunderstorms Sunday afternoon over NE FL and SE GA. High temperatures will be warmest over north central FL with readings around 80 degrees with mid to upper 70s over NE FL, low 70s along the SE GA coast and near the FL/GA state line with upper 60s NW of Waycross. Sunday night, showers will continue over SE GA as the strengthening surface low moves NE from the MS/AL Gulf coast into northern GA with a lull in activity over NE FL as the cold front approaches from the west, but with skies remaining mostly cloudy with light winds from the south veering southwest towards dawn. Lows will be above average in the 55-60 degree range over inland SE GA and the Suwannee valley of NE FL and 60-65 degrees from the SE GA coast into NE FL along and east of I-75. The Cold front will cross the area on Monday during the morning hours with a round of showers and isolated thunderstorms crossing our area. The best low level instability will lie south of the region while the strongest dynamic energy pushes over the area along and just ahead of the cold front which will clear the area by the afternoon. Showers will end from west to east with the last of the showers moving into the Atlantic waters by the afternoon with drier air and breezier conditions moving in behind the front as a much colder air mass builds into our region thanks to a strong upper low over the Ohio Valley and cold high pressure near the southern plains promoting NW flow over our area. Highs in the 60s over SE GA and the suwannee valley of NE FL will peak in the late morning hours with temperatures quickly falling into the 50s during the afternoon behind the front. Highs over coastal SE GA and NE FL areas east of I-75 will top out in the low to mid 70s and then fall into the low 60s by sunset.

LONG TERM [Tuesday Through Saturday]. The period will begin with drier and colder conditions over the area as a deep mid/upper level trough carves through the eastern third of the country. Strong high pressure near NW Gulf coast will build eastward over the region into Wednesday and then move NE of the region on Thursday with mostly clear skies and below seasonal temps through Thursday morning. Tuesday's highs are forecast to stay in the 50s for all of NE FL and only the upper 40s near the Ocmulgee/Altamaha river basin in SE GA. Lows on Tuesday morning will dip into the low to mid 30s across southeast Georgia and Suwanee Valley while falling into the upper 30s and low 40s along the coast and over north-central Florida. Wednesday morning will be the coldest morning of the season as the surface high builds directly over the area with very light winds allowing low temperatures to fall into the low 30s over NE FL along and west of I-95 with upper 30s to near 40 at the coast while subfreezing temps appear likely over inland SE GA and the suwannee river valley of NE FL with low to mid 30s at the SE GA coast. Highs on Wednesday will recover only into the upper 50s over SE GA and around 60 degrees over NE FL with a slight warming trend on Thursday with highs rebounding into the 60s over SE GA and upper 60s to near 70 for NE FL locations.

Another mid/upper level trough will swing SE from the upper midwest towards the southeastern states with a another surface low developing along the northern Gulf coast Friday into Saturday. Model differences at this time displace the timing and location of the best chances for rainfall so have kept scattered chances for showers with an isolated storm possible over the area by next weekend as the system moves east. Temperatures on Friday will return briefly to near seasonal values before cooling to below seasonal values by this weekend.

AVIATION. [Through 12Z Sunday]

Widespread stratiform rain will approach SSI and bring MVFR to IFR restrictions this morning along a slow moving frontal zone with a low potential for embedded tstorms. Rain shield will shift southward toward the FL terminals through midday, but will gradually break apart into more shower activity as the parent upper level disturbance moves offshore of the Atlantic coast. Restrictions of MVFR to IFR due to low ceilings near the front are expected at VQQ, JAX and CRG with passing rain/showers through the afternoon. The front and shower activity will approach GNV and SGJ into the early afternoon, with potential restrictions to MVFR. WSW winds this morning 4-8 kts will gradually transition to WNW to NNE as the front settles southward through this evening. The front will stall across N-central FL tonight as a weak area of low pressure forms offshore along the NE FL coast along the meandering frontal zone. This low will bring NNE flow along the coast as well as low stratus with high confidence of restrictions expected to ceilings lower overnight into the IFR to IFR range as low ceilings near the coast spread inland under NNE flow.
