Area Forecast Discussion National Weather Service Jacksonville FL 800 AM EST Thu Dec 5 2019

UPDATE.

No changes. The warming trend will continue today, with highs reaching mid 60s immediate coast and the upper 60s the over the rest of SE GA and NE FL. Dry conditions are still expected, with a bit of cirroform cloudiness.

AVIATION. [Through 12Z Friday]

VFR conditions during the next 24 hours. Winds becoming more northerly this mid morning, then northeasterly this afternoon at 5-10 kts.

PREV DISCUSSION [241 AM EST].

NEAR TERM [Through Tonight]. High pressure will build over the southeastern U S. Today. with sunshine along with some high clouds expected. High temperatures will be several degrees warmer Today, with mid 60s east of I-95 corridor, upper 60s further inland. With mostly clear skies Tonight, low temperatures will drop to around 40 interior SE GA, lower-mid 40s elsewhere inland, near 50 coast.

SHORT TERM [Friday through Saturday Night].

An upper level shortwave will move through into the lower MS Valley Fri morning, with developing area of surface low pressure over the ArkLaTex. A developing warm front extending east of this low will lift northward as the low moves eastward through the day, lifting north across SE GA and NE FL in the afternoon hours. With weak forcing from this warm front and a slight increase in PW values to near 1", there will be a slight chance (10-20%) for showers and thunderstorms Fri afternoon/evening. The warm front will also allow for an increase in daytime temperatures, which will return to the low-mid 70s across much of the area and overnight lows will be in the upper 40s.

As the low continues eastward Friday night, both the GFS and ECMWF show the northern center of low pressure weakening/dissipating, but another one developing further south along the cold front, over the northeastern Gulf waters. As the upper level shortwave races eastward, even this second surface low will lose its definition, leaving a stalled front over/just north of our area. Chances (20-30%) for showers will linger over the area Sat/Sat night. Highs Sat will be in the mid 60s to low 70s and overnight lows will be in the upper 40s to mid 50s.

LONG TERM [Sunday through Thursday Night].

The stalled front will remain more or less in place through Sun night before lifting northward Mon morning. On Mon, another upper level short wave will move into the central/northern Plains, onto the mid/upper MS Valley, moving into the Great Lakes region on Tues. This disturbance will develop another cold front which will push eastward across the area Tue afternoon-Tues night, probably bringing with it a thin line of showers. Models are also showing a secondary, mostly-dry cold front behind the main front, which could also bring a low end chance for showers Wed afternoon. Temperatures will gradually warm through mid-week ahead of Tues night's cold front, into the upper 70s to 80 on Tues, with overnight lows mostly in the 50s. Wed and Thurs behind the front, temperatures will return to near normal values with highs in the upper 50s to mid 60s and lows in the upper 30s and low-mid 40s.

MARINE. High pressure will build over the southeastern U.S. Today, with a weakening pressure gradient, and thus somewhat lighter winds, across the waters. The high will build north of the waters Tonight and weaken Friday while a weak cold front moves across the waters Friday night. High pressure will build north of the waters during the upcoming weekend.

Rip Currents: Low risk through Friday.

FIRE WEATHER. With low level ridging building today and continuing to slide east tomorrow, transport and 20 ft winds will be lower than the past several days, keeping dispersions on the low side (but still peaking above 20 in the afternoons). RH will dip to around 28% across most of the area this afternoon, but with light winds, we won't reach red flag criteria anywhere. Humidity values will increase tomorrow.

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.
