Area Forecast Discussion National Weather Service Jacksonville FL 231 PM EST Thu Dec 5 2019

Near Term. /through Friday/ .

High pressure will move to the northeast tonight through Friday. An inverted trough is expected to develop over the coastal waters overnight, which will strengthen during the day Friday. This trough could result in a few showers near the coast, but most of this activity is expected to remain offshore. An area of low pressure will also gather along the central gulf coast Friday afternoon, with its associated warm front extending east toward SE GA.

Temperatures will be near normal tonight, then above normal for Friday.

Short Term. /Friday night through Monday/ .

The forecast area will be between an inverted trough over the coastal waters and an area of low pressure to the west Friday night. A weak frontal boundary will extend between these two systems, but high pressure centered to the north will minimize the effect of this boundary, and largely push it to the south, but a few showers will be possible. The eastern inverted trough will move away to the east on Saturday, as the western low gets a little closer with an associated frontal boundary stretching across NE FL. High pressure will ridge into the area from the north Saturday, which will limit precipitation chances near the front. The ridge is expected to strengthen to the north Saturday night, then weaken and move northeast Sunday into Monday, while a weakening wave will be located to the west. While passing showers can not be ruled out Sunday into Monday, the chance will be low.

Temperatures will trend above normal this period.

Long Term. /Monday night through Thursday/ .

High pressure will be to the east Monday night into Tuesday. Long range models diverge on timing of next frontal system, which will arrive in the Tuesday to Tuesday night timeframe. At this point, will favor average of solutions, with an arrival of weakening front Tuesday afternoon into Tuesday evening, passing to southeast by Wednesday morning, with strong high pressure building to the northwest behind it. The high is expected to build to the north Wednesday into Thursday, with resultant onshore flow producing potential for mainly coastal showers.

Temperatures will trend above normal into Tuesday, then below normal for Wednesday and near to above normal for Thursday.

Marine.

High pressure will move to the northeast through Friday, as an inverted trough develops over the coastal waters. This trough will move to the east Friday night into Saturday, as a ridge builds from the north. High pressure will be to the north Saturday night into Sunday, as another inverted trough develops over the coastal waters. High pressure will build to the east Monday night into Tuesday.

Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
