AMZ400 Synopsis For Altamaha Sound Ga To Flagler Beach Fl Out To 60 Nm- 305 Pm Est Fri Dec 13 2019
Synopsis.. Strong southwest winds tonight will become more westerly in the wake of a cold front Saturday morning. A strong pressure gradient along this front will continue small craft conditions over our offshore waters through Saturday afternoon, possibly into the overnight period. After that, we'll have a brief quiet period with winds around 10 knots through Tuesday until another front approaches the area mid-week.

Area Forecast Discussion National Weather Service Jacksonville FL 101 PM EST Fri Dec 13 2019
AVIATION. [Through 18Z Saturday]
Low stratus and fog expected along with showers with embedded thunderstorms this afternoon. A break in the showers is anticipated this evening, but the low conditions will persist. A cold front will bring a round of strong to severe storms during the night. Conditions will slowly improve Saturday morning.
PREV DISCUSSION [935 AM EST].
NEAR TERM [Through Tonight].
Today . Warm front currently lifting northward through NE FL early this morning will be the focus of rainfall with isolated embedded storms possible as it moves into SE GA later this morning, then current shortwave energy over the NE GOMEX will track from the SW across this feature and push some fashion of broken squall line from west to east across SE GA/NE FL during the afternoon hours. Trying to nail down any specific area with strong/severe threat this afternoon will be tough and depends on how far warm front makes it northward and allows for warm sector destabilization. Max temps will range widely from the lower/middle 60s across SE GA closer to frontal boundary to lower/middle 70s across NE FL in the warm sector. Overall 12 hour rainfall chances today easily close to 80-100% for all areas, but areas in the warm sector across NE FL may see longer periods without rainfall as warm front lifts into SE GA. Locally heavy rainfall today appears more on track for SE GA as warm front focuses on this area as shortwave energy aloft pushes into the region.
Tonight . Digging mid/upper level trough into the SE US will acquire a negative tilt as significant piece of energy digs into the base of the trof later tonight. This will allow for a developing low pressure center on the frontal boundary over the FL panhandle that will track E-NE across south GA through the overnight hours and is rather intense for mid-December and higher res models such as the Downscaled NAM to 2.5 km is showing a significant squall line tracking across SE GA and into NE FL from the 06z-12z time frame (overnight hours) and is likely some of reason why SPC has introduced a Slight Risk of Severe Storms for much of the region as the warm sector from most of SE GA and into NE FL will allow for surface based storms and potential strong to severe wind gusts as this feature pushes through along with the risk for isolated tornadoes. The GFS/ECMWF are not quite as robust as the NAM with this feature on the latest model runs and will need to be monitored for better agreement. Overall expect locally heavy rainfall to accompany this squall line as well and still expect rainfall totals of 1-3 inches across SE GA and 0.50 to 1.50 inches across NE FL. Temps will generally remain steady in the 50s across SE GA and 60s across NE FL for most of the night ahead of the squall line with a slight decrease to around 50 degrees for SE GA behind the squall line towards morning.
SHORT TERM [Saturday Through Sunday].
Some rain showers may linger Saturday morning as a cold front exits the region. Dry conditions prevail as high pressure settles over the region for the weekend. Temperatures begin to warm as developing southerly flow starts advecting warmer air to the area late Sunday. Over the weekend, highs will generally range from the upper 60s across southeast Georgia to the low 70s across northeast Florida.
LONG TERM [Monday Through Thursday].
The warming trend continues for the beginning of the week with high pressure overhead. Temperatures rise well above climo with highs peaking in the mid to upper 70s with the potential for our southern counties to reach 80. On Tuesday, the next round of rain moves through ahead of a cold front. Behind the cold front, a colder, drier air mass moves into the area. Temperatures drop below climo til the end of the work week. Overnight lows on Wednesday and Thursday will range from the 30s inland to the 40s along the coast.
MARINE.
ENE winds over the GA waters just north of lifting warm front this morning were near 15 kts at Grays Reef buoy 41008 early this morning with combined seas 6-7 ft. Winds over FL waters were veering SSE trailing warm frontal boundary lifting northward with winds generally 10-15 kts. Front is expected to drift northward and linger over or just north of our GA waters this afternoon. Winds will steadily veer more southerly into the afternoon with decreasing speeds to near 10 kts over nearshore waters to 10-15 kts for all offshore waters with gradually decreasing wave heights. Small Craft Advisory (SCA) for nearshore waters is expected to be downgraded to a Small Craft Exercise Caution this afternoon with a continued SCA for the outer waters through Saturday due to elevated seas and stronger post-frontal winds. Waves of showers and t'storms will impact the adjacent waters through early Saturday morning, with clearing conditions through midday Sat and a dry rest of the weekend.
Rip Currents & Surf: Dangerous surf conditions continue today with a high rip current risk and large, rough surf with breakers of 4-7 ft reported along the local coast. A high surf advisory (breakers of > 7 ft) remains in effect for NE FL beaches today. Waves and winds will decrease through the day as flow becomes more southerly.
