Area Forecast Discussion National Weather Service Jacksonville FL 157 AM EST Mon Dec 9 2019

NEAR TERM [Through Tonight].

Scattered showers over the offshore coastal waters are expected to dissipate over the next few hours as they move north. Low stratus and fog was across much of northeast Florida and portions of southeast Georgia this morning. Patchy dense fog was already developing, and areas of dense fog will likely develop before daybreak. This will continue to be monitored and a Dense Fog Advisory could be required for portions of the area. The fog and low stratus will lift and scatter out by noon. A warm front was lifting northward across the area early this morning, and will be near the Altamaha River by daybreak. Surface high pressure was located east of the Northeast conus, with the surface ridge axis south of the area. Light southerly flow will prevail today, and with a warm front pushing northward through the region, temperatures will be well above normal today. Temperatures this morning will be in the 50s and lower 60s. Highs will be get near records, with highs climbing into the upper 70s to lower 80s this afternoon. Dry conditions are forecast to prevail today, with isolated showers remaining generally west of the area.

Fog and low stratus are forecast to develop tonight. However, the fog and low stratus is forecast to move in from the Gulf in the south southwest flow. This may keep the fog and stratus mainly along and to the west of Highway 301. Overnight lows will be mild in the mid 50s to low 60s.

SHORT TERM [Tuesday Through Wednesday].

Potential for fog development will continue into Tuesday morning, with inland areas most likely to have reduced visibilities. Chances for rain will increase by Wednesday as a trough ahead of the cold front moves in towards Georgia. Near record max temps on Tuesday with high temperatures peaking into the lower 80s throughout the forecast area. Temperatures on Wednesday will be noticeably lower with highs in the 60s over inland southeast Georgia and in the 70s for northeast Florida. Above average low temps are expected through the middle of the week, with temperatures ranging between the upper 50s and lower 60s Tuesday night down into the 40s over southeast Georgia and in the 50s for northeast Florida on Wednesday night.

LONG TERM [Thursday Through Monday].

Chances for showers and storms for the end of the week, with strong winds developing out of the north-northeast on Thursday and then returning to normal on Friday. A front moving in from out of the west will mark the end of the increased convection and lead to cooler and drier conditions on Sunday. High temperatures during this period are expected to range in the 50s & 60s before the weekend and then in the 60s and 70s during the weekend. Overnight low temperatures are expected to be in the 40s and 50s during this span.

AVIATION. [Through 06Z Tuesday]

IFR/LIFR cigs and vis will prevail at the TAF sites for the rest of the night. Fog and stratus will lift and scatter out by the mid to late morning, with southerly winds 5-10 knots prevailing. VFR conditions will prevail Monday afternoon through the end of the TAF period.

MARINE.

The surface ridge axis will shift south of the area today through Tuesday with winds becoming south to southwest. A cold front will push across the waters on Wednesday and then stall south of the waters before lifting back north at the end of the week. Strong Small Craft Advisory conditions will likely develop Wednesday night through Thursday night as the pressure gradient tightens with strong high pressure building to the north, and occasional to frequent Gale force gusts are also expected. Scattered to numerous showers are expected with isolated thunderstorms possible Tuesday night through Friday.

Rip Currents: Moderate risk of rip currents at the northeast Florida and southeast Georgia beaches through Tuesday.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
