New AVIATION
SYNOPSIS
Issued at 326 AM EDT Fri Mar 29 2024
Overnight surface analysis depicts high pressure (1022 millibars)
blanketing the Tennessee and lower Mississippi Valleys, with this feature building into the Deep South in the wake of Thursday's cold frontal passage
Aloft
a potent, negatively tilted trough positioned along the Mid-Atlantic coast was lifting northward, creating a dry northwesterly flow across our region. Skies have cleared out overnight throughout our region, with cool air advection driving temperatures down to around 50 degrees across inland portions of southeast GA as of 07Z, ranging to around 60 along the northeast FL coast. A wider range of dewpoints exist across our area, with low and mid 30s across inland portions of southeast GA, while values remain in the low and mid 50s along the northeast FL coast.
NEAR TERM
(Today and Tonight)
Issued at 326 AM EDT Fri Mar 29 2024
Our local pressure gradient will remain tight this morning as low pressure strengthens off the New England coast and high pressure continues to build towards our region. This weather pattern will yield breezy northerly winds this morning, followed by diminishing onshore winds this afternoon as high pressure begins to settle over our area, allowing our local pressure gradient to loosen.
Plenty of sunshine, a dry air mass, and weakening cool air advection this afternoon will allow highs to climb into the 70s at inland locations, while an onshore breeze keeps coastal highs in the mid to upper 60s.
Flow aloft will become zonal tonight, allowing for thin cirrus to drift across our region from the west after midnight. Otherwise, high pressure will settle directly over our area, allowing for radiational cooling. We nudged low temperatures a few degrees below model blends tonight to account for the dry air mass and decoupling winds shortly after sunset, which will result in lows falling to the 40s region-wide. These values will be about 5-10 degrees below late March climatology.
SHORT TERM
(Saturday through Sunday)
Issued at 326 AM EDT Fri Mar 29 2024
The influence of high pressure will remain in place through the weekend, resulting in dry weather and mostly clear to partly cloudy skies through the period. Temperatures will warm through the weekend with daily high temps rising into the upper 70s and lower 80s before the end of the weekend. Overnight low temperatures will similarly warm up into the mid to upper 50s.
LONG TERM
(Monday through Thursday)
Issued at 326 AM EDT Fri Mar 29 2024
High pressure will move off to the east by Tuesday, with increased chances for showers and storms beginning in the period between Tuesday afternoon and Wednesday morning as a cold front presses in from out of the west. At current, the front is expected to push across the forecast area by Wednesday night with high pressure conditions returning over the region on Thursday. Above average temperatures are anticipated for the beginning of next week with temps dipping to be closer to near and below the seasonal average by midweek.
AVIATION
(12Z TAFS)
Issued at 716 AM EDT Fri Mar 29 2024
VFR conditions will continue through the entire 12Z TAF period.
Northerly winds near 10 knots along the coast and 6-8 knots inland will rise to 8-10 knots inland and breezy along the coast 12-14 knots by 14Z with gusts 16-20 knots as high pressure builds into the region today from the west. Winds will become northeasterly this afternoon for most sites except SGJ and slowly relax to 5-8 knots under persistent clear skies. After 00Z, winds will become very light along the coast with a southerly component at SSI and more easterly at SGJ while becoming calm inland.
MARINE
Issued at 326 AM EDT Fri Mar 29 2024
High pressure building into the southeastern states this morning will become centered directly over our local waters this evening and will then shift offshore on Saturday. Gusty north- northeasterly winds this morning will shift to east-northeasterly with diminishing speeds this afternoon. Small Craft should Exercise Caution throughout our local waters this morning due to speeds of 15-20 knots. Small Craft should Exercise Caution through tonight if venturing beyond 20 nautical miles offshore, where seas of 4-6 feet will prevail.
Seas will continue to gradually subside below Caution levels offshore on Saturday as winds shift to a prevailing southerly direction. Seas of 2-4 feet are expected both near shore and offshore from Saturday night through Tuesday. South-southwesterly winds will prevail through Tuesday, with speeds then increasing on Tuesday afternoon and evening ahead of an approaching strong cold front. Caution level speeds of 15-20 knots are forecast offshore on Tuesday night. Showers will be possible after midnight on Tuesday night.
Rip Currents: Breezy onshore winds today will create a moderate rip current risk at all area beaches. A long period northeasterly ocean swell will arrive at area beaches on Saturday and will persist through Monday, keeping a moderate rip current risk in place.
HYDROLOGY
Issued at 326 AM EDT Fri Mar 29 2024
Minor flooding will continue during the next several days along upper portions of the Altamaha River near the Baxley gauge as well as along lower portions of the Satilla River near the Atkinson gauge. Water levels along lower portions of the Santa Fe River near the Three Rivers Estates gauge may rise above flood stage during the early to mid portions of next week.
