Area Forecast Discussion National Weather Service Jacksonville FL 800 AM EDT Wed Oct 20 2021

UPDATE.

The forecast remains on track this morning with no significant updates. Today will be warmer with highs in the low 80s and continued dry with stratocumulus moving onshore around High pressure to the north. The high will move to our east tonight while more high clouds arrive from the west due to increasing high level winds running over the top of an upper ridge to our SW over the Gulf of Mexico which will decrease chances for fog by early Thursday morning. Overnight lows will be near seasonal levels in the mid to upper 50s over inland SE GA and around 60 degrees over the coast and NE FL areas.

PREV DISCUSSION [755 AM EDT].

NEAR TERM [Through Tonight].

Synopsis . Passing clouds, continued dry and a little warmer with inland morning fog potential.

This morning a surface high was centered over GA/SC with a weak coastal trough offshore of the Fl Atlantic coast. Light onshore flow continued to stream stratocumulus onshore across NE FL with high cirrus streaming across the area over a de-amplifying ridge across the GOMEX. Patchy intermittent fog was forming under the low level ridge center across inland SE GA and generally along and north of the I-10 corridor, and this will continue through sunrise with localized visibilities near 1 mile at times.

Partly to mostly sunny skies will prevail through midday, with thickening high cirrus from the west into the afternoon and evening. High temperatures will warm 1-2 deg higher than yesterday, generally ranging in the low 80s to near 80 along the coast where mild onshore flow will persist.

The low level ridge center will shift farther offshore tonight with a ridge axis sliding southward across the I-10 corridor with a continuation of high cirrus aloft, thinning toward sunrise as upper level flow becomes zonal. Low temperatures will moderate further tonight, trending more toward climo values ranging from the mid/upper 50s inland SE GA to low/mid 60s along the coast and south of the I-10 corridor. Conditions favorable for fog formation after midnight tonight, especially near the I-10 corridor under the ridge axis. Passing high clouds will limit ideal radiational cooling conditions, so indicated just patchy fog for now.

SHORT TERM [Thursday Through Friday].

Thursday, mean low level flow will transition to southwesterly ahead of a slow moving and weak front entering the southeast US. This flow will advect low and mid level moisture into the region. Meanwhile in the upper levels, zonal flow and subtle embedded impulses will bring abundant high clouds. The forcing with the impulses is far too weak to be confident in shower development. A thick cirrus deck should prevent extensive fog development Thursday night.

Friday, a prefrontal trough will develop ahead of the aforementioned front. Shower chances will be highest (around 30%) as the prefrontal trough sags southward into southeast GA Friday afternoon. Precip chances dwindle as the front pushes further south into northeast Florida Friday night. With a shorter period of diurnal heating, broken cloud cover, and little upper forcing to speak of, the potential for embedded thunder remains low.

Warming will continue ahead of the front through the end of the week. Advertising highs in the low 80s across southeast GA and mid to upper 80s in northeast FL both afternoons.

LONG TERM [Saturday Through Wednesday].

The front is progged to exit to our south and then eventually stall over central or southern FL. Post-frontal airmass will quickly modify as onshore flow develop Saturday afternoon. The moistening onshore flow will continue into early next week as surface ridging shifts to the northeast. Daily coastal troughs are progged to develop over the Atlantic and shift inland Sunday and Monday. Increasing moisture with these features will renew rain chances along the northeast FL coast. Significant cooling is not expected behind the front. Temperatures will remain warm, with low to mid 80s for highs except in north-central FL where readings are expected to be in the upper 80s.

AVIATION. [Through 12Z Thursday]

VFR conditions will prevail during the 12Z TAf period. Brief patchy fog has eroded from earlier this morning with some VFR ceilings between 4.0 and 5.0 kft moving onshore from the Atlantic through today around high pressure north of the terminals. Winds will increase from the east around 8-10 knots at the coastal terminals and around 5-7 knots at the inland TAF sites. High pressure will move east of the regional terminals this evening and high clouds will increase from the west after 23Z as winds diminish and become light from the east less than 5 knots and then become near calm near by 09Z for the inland TAF sites and duval terminals with southeast winds around 5 knots at the coastal sites to end the 12Z TAf period.

MARINE.

No headlines are expected through the weekend as winds clock from easterly today to southerly Friday ahead of a front, then veer northerly Saturday trailing the frontal passage. Surface high pressure over the southeast region will build offshore of the Atlantic coast through Thursday. A weak cold front will approach from the north Friday then move south of the waters through early Saturday. High pressure will build north to northeast of the local waters through the weekend.

Rip Currents: Moderate risk today for all local beaches. Low risk expected Thu for SE GA beaches and likely for FL beaches as light SE winds develop.

FIRE WEATHER.

High pressure centered over southeast GA will lead to weak transport flow and low afternoon dispersion today. More favorable easterly flow across northeast FL will lead to patchy areas of high dispersion today. Poor to low dispersion is expected areawide as transport becomes light on Thursday. Afternoon humidity will continue to trend higher through the end of the week. A weak front will pass through Friday. This front will not offer much precip and dry conditions are likely to persist into early next week.

HYDROLOGY.

Minor river flooding continues along the Altamaha River basin and along the Satilla River at Atkinson.

Elevated tides will near Action Stage around high tides today with light onshore flow and today's full moon (Hunter's Moon).
