Area Forecast Discussion National Weather Service Jacksonville FL 645 PM EST Thu Mar 4 2021

AVIATION. [Through 00Z Saturday]

VFR expected through Friday. Some light fog possible early Friday morning near terminals, but recent guidance and observations suggest low fog chances and brief occurrences, if any. Light east to southeast winds at 23Z near the coast and northwest inland will become variable to near calm overnight. Weak backdoor cool front will march down the southeast U.S. coast late tonight and Friday morning, passing through the terminals between about 10Z and 15Z. Winds will begin to transition to northwest and then north by 12Z. A breezy north-northeast flow 8-12 kt expected between 13Z-18Z, then weakens somewhat by 21Z. Increased high clouds expected by mid to late day Friday with a few stratocumulus possible at times.

PREV DISCUSSION [240 PM EST].

Near Term. /through Friday/ .

Ridge of high pressure will extend southeast then south across the region Tonight through Friday. Subsidence under this ridging will provide mainly clear skies. Anticipating some high cloudiness moving into western counties late in the day, ahead of an approaching low pressure system.

The position of the ridge will provide for a northwest to north flow Tonight, with temperatures falling to a little below seasonal levels. For Friday, the flow will become more from the northeast. This will keep northern and eastern counties significantly cooler than more inland NE FL Friday. For example, beaches will max in the lower to mid 60s, Jacksonville upper 60s, while Gainesville gets into the mid 70s. SE GA will be fairly consistently in the mid to upper 60s, coolest at the coast.

Latest high resolution short term model data depicting fog development along the I95 corridor overnight. This would be in an area that had best moisture convergence this afternoon due to the sea breeze, so possible this moisture settles into a fog layer. For now, starting with a mention of patchy fog for the highway corridor, and will continue to monitor.

Short Term. /Friday night through Monday/ .

Strengthening high pressure will build from the north northwest Friday night into Saturday, while an area of low pressure moves east over the gulf Friday night, then across southern FL Saturday. The models have been trending toward a stronger high to the north, which is forcing the low track further south, resulting in lower rain chances, especially for SE GA.

Current forecast track and timing will focus highest precipitation chances north of the low track, over north central FL during the day Saturday. Chances will arrive Friday night, as warm frontal zone stretches east across northern FL ahead of the low. The gradient between rain and no rain could be pretty sharp with this event, with areas in SE GA north of Waycross getting little if any rainfall, while areas south of JAX have a predominantly rainy day Saturday. If the trend toward a stronger high continues, the rain shield will shift even further south.

The low pressure system will exit to the east southeast Saturday night, with high pressure building across area from north northwest through Sunday. The fairly strong high will become centered just to the north Monday. Mainly clear skies are expected Sunday into Monday. A surge of northeast winds will work down the coast Saturday night into Sunday following the low passage, which will produce gusty winds near the coast.

Temperatures will trend a little above normal Friday night due to onshore flow and expected cloud cover. Below normal temperatures are anticipated Saturday through Monday.

Cool enough for a little patchy frost over inland SE GA Saturday night, but much better frost coverage potential will exist for Sunday night across inland SE GA, and possibly into the Suwannee valley of NE FL. Given the strength of the high Sunday night, could see the cooler temperatures spread a little further south across area. Will be monitoring this over the next few cycles, as a significant frost event possible.

Long Term. /Monday night through Thursday/ .

Strong high pressure will be centered just to the northeast Monday night, with the high slowly moving further to the northeast through the period, but the ridge will continue to extend back across forecast area. Due to ridging this is expected to be a dry period, with partly cloudy skies.

Temperatures will also moderate through the period, with near normal readings into Tuesday, then above normal through Thursday.

Marine.

High pressure ridge will build from the north northwest through Friday. An area of low pressure will track across the gulf Friday night, then across southern FL Saturday. This low will exit to the east southeast Saturday night. High pressure will build to the northwest Sunday, then north Monday, and northeast Tuesday through Thursday.

Advisory level conditions expected Saturday night through Sunday.
