NEAR TERM
(Today through Tonight)
Issued at 245 AM EDT Wed Apr 24 2024

For the latest NE FL and SE GA Daily Key Messages please visit: https:// www.weather.gov/media/jax/briefings/nws-jax-briefing.pdf

High pressure will dominate the pattern today with clear to partly cloudy skies. Some very patchy light ground fog is possible in inland areas through sunrise. A weak sea breeze will develop near shore and will move inland 20 to 40 miles through the evening hours. High temperatures will be in the lower 80s inland and the lower to mid 70s at the coast. Low temperatures will be in the mid to upper 50s inland and the lower to mid 60s coastal.

SHORT TERM
(Thursday through Friday night)
Issued at 245 AM EDT Wed Apr 24 2024

Weak cold front will move into our southeast GA zones Thursday morning and afternoon while tending to become more diffuse. High pressure will build to the north of the front Thu night helping to drag it further southward into Friday. Any progged isolated shower activity with the front is only likely to be over the coastal waters during this time frame.

High pressure continues to build in across the east coast Friday while the west-east oriented front is diffuse near the FL/GA state line. Low level flow turns more east to southeast and enough moisture and sfc convergence are available to spark a couple of showers. Upper levels are too stable and suppressed for any t-storm activity. For now, will increase the chances a bit to around 10-20 percent area-wide with support from latest MOS and blended guidance.

Temps will be near normal during this period.

LONG TERM
(Saturday through Tuesday)
Issued at 245 AM EDT Wed Apr 24 2024

Fairly quiet conditions this period with a mid/upper level ridge over the region. A strong mid/upper level trough across the southwest U.S. lifts to the northeast while an associated front moves to the Ohio and TN valleys by Mon night. It will tend to be breezy from easterly flow Saturday and possibly Sunday during the daytime with a decent pressure gradient in place with center of the high just off the New England coast. The high moves into the region by Sunday night and into early next week. We could see some isolated showers on Saturday but few and far between for most areas with limited mid/upper level moisture, and maybe even less chances on Sunday. A shower or two still possible across the coastal waters.

High pressure ridge will be over the area on Monday and most of Tuesday, though the tail end of a weak cold front may move into the area by Tuesday night, but little moisture appears available for much of any precip.

Temps will be close to normal values through the weekend with a trend towards above normal temps early next week as the ridge axis slides southward. These high temps will generally be in the mid/upper 80s over far inland areas, with lower 80s along the I-95 corridor and around 80 each day along the Atlantic Coastal areas.
More widespread mid to upper 80s anticipated for Tuesday.

AVIATION
(12Z TAFS)
Issued at 731 AM EDT Wed Apr 24 2024

VFR conditions and light winds under the influence of high pressure. An afternoon sea breeze will push an ESE wind into the coastal terminals this afternoon, around 8-11 kts. Potential for localized vsby reduction at KVQQ but otherwise VFR expected overnight.

MARINE
Issued at 245 AM EDT Wed Apr 24 2024

High pressure will dominate the waters through tonight with a sea breeze developing near shore during the afternoon and evening hours. A weak trough/front will approach the waters on Thursday with high pressure building back in through the remainder of the forecast period.

Rip Currents: Moderate risk today and Thursday.

FIRE WEATHER
Issued at 245 AM EDT Wed Apr 24 2024

Low RH values into mainly the mid 30 percent range expected today and Thursday, though some pockets to near 30 percent are possible inland areas. Sfc winds and transport winds are slightly higher today just to the northeast of Alma GA may lead to high dispersion values. By Friday, high dispersion looks more probable for many areas as sfc and transport winds will be higher. This is headlined in the latest FWF.
