Area Forecast Discussion National Weather Service Jacksonville FL 216 AM EST Sat Jan 25 2020

. COOLER AND DRY THIS WEEKEND .

NEAR TERM [Through Tonight].

Cooler and dry today in the wake of an early morning cold frontal passage. Surface high pressure will build across the central Gulf Coast states with a dry WNW flow over the local area and seasonally cool temperatures as high temperatures rise into the 60s under mostly sunny skies. Tonight, low temperatures will fall into the mid to upper 30s inland to the low 40s along the St. Johns River basin and Atlantic coast. Could have some inland patchy frost especially across the Suwannee River Valley where winds will be lightest under the influence of the ridge axis, however, conditions not favorable for widespread frost development with passing high clouds aloft and elevated boundary layer winds as a weak surface trough axis slides offshore of the SE Atlantic Bight.

SHORT TERM [Sunday Through Monday].

Sunday will start off cold and clear, with skies becoming gradually more cloudy as the day progresses. A weak shortwave associated with low pressure moving across the Florida peninsula will bring in light precipitation for most of the forecast area throughout much of the day, with conditions clearing in the evening. Daily max temps are expected to be close to the seasonal average, with temperatures reaching into the mid 60s in the afternoon. Overnight low temperatures in the 40s Sunday night and dropping into the upper 30s in southeast Georgia with the passage of the instability.

LONG TERM [Tuesday Through Saturday].

Dry weather expected for Tuesday as high pressure settles in over the region, however the models are in disagreement as to when the next wave of instability is expected to cross over the southeastern US. GFS indicates convection associated with a trough moving across the forecast area on Wednesday and Thursday, however the ECMWF models indicate much more subdued conditions. Both models do expect a Gulf low to bring in foul weather by the end of the week, but currently disagree on which day that it will actually arrive on. High temperatures for the week are expected to range between the mid 60s and lower 70s, with overnight low temperatures warming from the lower 40s up into the mid to upper 40s by the end of the week.

AVIATION. [Through 06Z Sunday]

Low stratus associated with cold front passage early this morning will bring MVFR to IFR restrictions through 10Z with WSW winds generally 10 kts or less with gusts near 13-18 kts with frontal passage. Prevailing VFR conditions after daybreak with WNW winds 10 kts or less. Winds may back slightly late afternoon into the evening WNW as speeds decrease to less than 5 kts with prevailing VFR conditions tonight.

MARINE.

High pressure will build east across the Gulf Coast today and tonight trailing early morning cold front passage. Elevated combined seas of 6-8 ft will continue Advisory conditions over the outer waters with near shore water combined seas of 4-6 ft continuing Small Craft Exercise Caution conditions. Winds will be WNW near 15-20 kts today.

The high will center over the local waters Sunday with offshore flow and further dampening of wave heights expected fall below Advisory criteria for the outer waters. An area of low pressure will track across south Florida Sunday night and Monday. High pressure will build north of the local waters Tuesday and Wednesday as another area of low pressure forms in the Gulf of Mexico. Headlines are not expected beyond Sunday with a weak pressure pattern in place.

Rip Currents: Moderate rip current risk today and Sunday under offshore flow. Breakers will lower into the 3-5 ft range today along the NE FL coast.

HYDROLOGY.

Minor river flooding continued along portions of the Altamaha River basin.

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
