Area Forecast Discussion National Weather Service Jacksonville FL 412 PM EST Thu Nov 21 2019

NEAR TERM [Through Friday night].

Surface high pressure across the Carolinas will weaken some and shift Se tonight which will relax the gradient over the area. With light winds and slightly elevated moisture levels could have patches of late night and early morning fog across the inland areas. A warming trend commences Friday as the deep layer ridge shifts further Se with the approach of a cold front. Will have an increase in high clouds but a continuation of dry conditions with afternoon temps well into the 70s inland areas and lower/mid 70s coast. Rather cool conditions tonight with lows mostly in the upper 40s inland to 50s coast. Lows Friday night mainly in the 50s most areas.

SHORT TERM [Saturday Through Sunday Night].

Predominately warm and dry conditions Saturday under partly cloudy skies with temps warming to slightly above normal. South to Southwest winds ahead of the front which will push afternoon temperatures well into the 70s again (warmest far south). Continued good agreement between the GFS and ECMWF with the cold front moving across Se Ga after midnight and Ne Fl early Sunday morning bringing a good chance of showers. The front will be coming through after loss of heating so instability will be limited. The cold front will push Se of the area Sunday morning with showers rapidly ending from Nw to SE and decreasing cloudiness. Cool high pressure builds in behind front ushering in a cooler and drier air mass. Afternoon temps mainly in the 60s.

LONG TERM [Monday Through Thursday].

Cool high pressure builds in resulting in a continuation of the cool and dry conditions into early next week with temps slightly below normal. The next cold front is forecast to traverse the area on Wednesday bringing a chance of showers. High pressure will build to the north of the area behind the front on Thursday. Temps will warm to slightly above normal on Wednesday then will be near normal Thursday.

AVIATION. [Through 18Z Friday]

Moderate winds from the east today will go calm overnight. With mostly clear skies today and with low level moisture increasing ahead of our next front, patchy fog is expected to develop in the early morning hours. Kept to 2SM vsbys with this package, but brief patches of LIFR conditions will be possible late tonight/early Friday. Vsbys are expected to improve shortly after sunrise, with light to calm winds through the end of the time period.

MARINE.

No headlines expected through Friday as high pressure builds over the coastal waters. A cold front will move across the waters Saturday night. South to Southwest winds increase out ahead of the front on Saturday and shift to the Northwest behind the front Saturday night and Sunday. SCA possible offshore and SCEC possible near shore Saturday night into Sunday morning. Winds decrease Sunday afternoon into early next week as high pressure builds across the waters.

HYDROLOGY. Water levels will continue to decrease some as onshore winds weaken tonight and become offshore on Friday. Water levels will continue to be elevated across Putnam and Flagler counties and will keep a Coastal Flood Statement going there through Friday morning.

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.
