Area Forecast Discussion National Weather Service Jacksonville FL 547 AM EST Sun Dec 8 2019

AVIATION. [Through 12Z Monday]

Low stratus was across interior southeast Georgia this morning. Earlier fog at KJAX and KVQQ has moved out as winds have increased from the northeast. Showers were over the coastal waters, and will be near KSGJ through much of the day. Showers may also impact the Duval County TAF sites in the mid to late afternoon. Northeast winds 10-15 knots with higher gusts will prevail through the day. The pressure gradient is forecast to weaken tonight due to an inverted trough east of the area lifting northward, and a boundary across central Florida lifting northward as a warm front. Low stratus and/or fog is forecast to develop shortly after sunset tonight, with IFR/LIFR conditions expected after midnight through the end of the TAF period.

PREV DISCUSSION [220 AM EST].

NEAR TERM [Through Tonight].

A shortwave was moving southward across north central Florida early this morning. The southward progression has ended the lift over the area, putting an end to the sprinkles across northeast Florida. At the surface, an area of low pressure was weakening across northern Gulf, high pressure was wedging southward east of the Appalachians, and an inverted trough was located east of the Bahamas. Some light patchy fog was developing early this morning, but not expecting dense fog due to increasing northeasterly flow. Showers were increasing over the Atlantic coastal waters. Scattered showers will move onshore northeast Florida this morning. Another coastal trough will develop east of the area and lift northward towards the Carolinas this afternoon as strong high pressure over the Mid Atlantic states shifts into the western Atlantic. The pressure gradient will then weaken and rain chances will lessen through the late afternoon and end in the early evening hours. Highs will be in the mid to upper 60s across southeast Georgia, and the low to mid 70s across northeast Florida. Lingering low level moisture and winds becoming light overnight will lead to areas to widespread fog, possibly dense, across the region. Overnight lows will be mild in the 50s.

SHORT TERM [Monday Through Tuesday].

Widespread areas of early morning fog is expected to dissipate by late Monday morning. Predominantly southwesterly flow will be out of the southwest as the frontal boundary moves in towards the region from out of the west-northwest, bringing in increased chances for convection for the beginning of next week. Above average temperatures throughout the region next week, with daily high temperatures reaching up into the upper 70s and lower 80s. Overnight low temperatures for Monday and Tuesday are expected to be in the 50s and 60s.

LONG TERM [Wednesday Through Sunday].

Wet weather is expected to begin midweek as the cold frontal boundary dips down over Georgia, bringing increased chances of showers and storms across the region on into the weekend. Temperatures will drop across the forecast area as the frontal boundary moves in, with high temps dropping into the 50s and 60s for southeast Georgia and in the 60s and 70s for northeast Florida, with the warmest temperatures occurring further to the south. Minimum low temperatures will be in the 30s & 40s for southeast Georgia and in the 40s & 50s for northeast Georgia, with the warmest temperatures occurring ahead of the frontal boundary.

MARINE.

A Small Craft Advisory remains in effect through this morning for the offshore southeast Georgia waters beyond 20 NM offshore due to northeasterly winds around 20 knots and seas around 7 feet. The tight pressure gradient this morning will relax this afternoon and evening as an inverted trough develops east of the area and moves northward towards the Carolinas. Scattered showers will continue over the coastal waters through the day, especially over the northeast Florida waters. The surface ridge axis will shift south of the area Monday through Tuesday. A cold front will push across the waters on Wednesday and stall near or just south of the waters through the end of the week. Small Craft Advisory conditions are forecast late Wednesday into Friday. Scattered to numerous showers are forecast each day.

Rip Currents: Moderate risk of rip currents northeast Florida and southeast Georgia beaches today and Monday.

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.
