Area Forecast Discussion National Weather Service Jacksonville FL 927 PM EST Tue Jan 28 2020

UPDATE.

Little change for the evening update. Mostly clear skies rest of tonight with a few mid and high clouds expected to push in from the west late toward sunrise ahead of the next low pressure system. Before that occurs, ideal radiational cooling will take place and allow for lows from 35-40 inland and closer to 40/lower near the coast. Patchy frost expected inland given the calm winds and mostly clear skies.

MARINE. Current forecast on track with light northeast winds expected rest of tonight. Seas around 2-4 ft mainly due to easterly swells.

PREV DISCUSSION [702 PM EST].

Near Term. /Through Tonight/ .

Center of surface high pressure will build from the northwest to the north through Tonight. Skies will be clear for most of Tonight, with high cloudiness streaming in from the west toward dawn. Lows in the mid to upper 30s expected inland Tonight, with readings in the lower to mid 40s near the coast. With light winds, coupled with the cool temperatures patchy frost expected inland, especially SE GA.

Short Term. /Wednesday through Saturday/ .

Low pressure will move east across the northeastern gulf Wednesday, and across central FL Wednesday night. Rain showers ahead of this feature will reach western forecast area late Wednesday morning, with this activity spreading across region Wednesday afternoon and evening. High pressure will build to the north northeast Thursday into Thursday night. Coastal troughing in the onshore flow could result in mainly coastal showers. An area of low pressure will move northeast from the gulf Friday and across the southeastern US. The associated cold front will move east across the area Friday night into Saturday. Rain showers will be possible ahead of this front on Friday, but the best chance will be Friday night. High pressure will build from the west Saturday afternoon. A bit of a warming trend expected this period, with readings a little higher than seasonal levels Friday and Saturday.

Long Term. /Saturday night through Tuesday/ .

High pressure will continue to build from the west Saturday night through Sunday, then overhead Monday. The high will move to the east Monday into Tuesday, as an area of low pressure approaches from the west. Rain showers are expected to move into the region Tuesday afternoon.

Temperatures will continue to trend above normal this period.

AVIATION. [Through 00Z Thursday]

VFR through much, if not all, this TAF period but we'll see increasing mid and high clouds Wednesday as a new storm system approaches the area. Late in the period around 19z-00z, cigs are expected to drop but for now have kept them around the 4-6 kft range (trending toward MVFR), with VCSH and possible light drizzle as lift increases ahead of the system. Further deteriorating conditions expected after 00z Thursday. Light to calm winds tonight become east to northeast at 5-10 kt on Wednesday.

Marine.

High pressure will build to the north northwest through Wednesday. An area of low pressure will track east across the area Wednesday into Thursday. High pressure will build to the north northeast Thursday night into Friday, with a trough developing along the coast. A cold front will move east across the area Friday night into Saturday 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.
