Area Forecast Discussion National Weather Service Jacksonville FL 307 PM EST Tue Jan 21 2020

Near Term. /Through Tonight/ .

The region will be between strong surface high pressure to the north northwest and developing low pressure to the southeast through Tonight. An upper trough will move southeast across the area this afternoon, which will help to strengthen the low to the southeast later Today into Tonight. The northerly flow will continue, which will keep the cooler than normal temperatures in the forecast. As the low strengthens the pressure gradient across the area will tighten, helping to keep winds elevated through the night, especially near the coast. So not only will it be on the cold side Tonight, but the winds will lead to even chillier wind chills.

Short Term. /Wednesday through Saturday/ .

The high will build more toward the north Wednesday, as the low moves toward the south and weakens. A few coastal showers will be possible Wednesday. The high will continue to the north northeast Wednesday night through Thursday night, as it begins to weaken. Weak coastal troughing will keep showers in the forecast, especially along the coast. A cold front will move toward the region, as an area of low pressure lifts northeast out of the gulf Friday. This low will move across the region in the base of the frontal boundary Friday afternoon into Friday night, bringing scattered to numerous showers. Another below normal day expected Wednesday, with temperatures returning to near normal Wednesday night into Thursday. Above normal temperatures expected Thursday night into Friday night. Readings will be closer to normal on Saturday following the cold front.

Long Term. /Saturday night through Tuesday/ .

High pressure will build from the northwest Saturday night through Sunday night, then overhead Monday into Tuesday. Dry weather is expected for this period, with near to below normal temperatures.

Marine.

The region will be between strong high pressure to the northwest and developing low pressure to the southeast through Tonight. The low will sink toward the southeast Wednesday, as the high moves toward the north. The high will be to the north Thursday, with the low to the southeast weakening. A cold front will move east across the region late Friday into Friday night, with high pressure building from the west behind it. The high will continue to build from the northwest over the weekend, then overhead early next week. Rip Currents: High Risk Wednesday.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

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.
