Area Forecast Discussion National Weather Service Jacksonville FL 657 PM EST Wed Jan 27 2021

AVIATION. [Through 00Z Friday]

Showers and isolated storms are moving east of the northeast FL area and leaving widespread IFR ceilings, with a chance of LIFR ceilings at times this evening. Improving cloudiness will develop late tonight from north to south as a cold front, currently located near the GA coast southwest to the northeast Gulf of Mexico, pushes further south of the area. VFR should be prevailing after 06Z-08Z, though may need to monitor SGJ for low ceilings lasting slightly longer there. Sfc winds are variable due to the front in the area, but will shift to the west around 8-12 kt later this evening, and then become more northwest around 06Z, and northerly by late morning near 10-15G22kt.

PREV DISCUSSION [316 PM EST].

NEAR TERM. [through Thursday] .

Frontal boundary extends NE to SW across forecast area early this afternoon with showers and embedded thunderstorms along it. The center of low pressure on this boundary has entered into the western counties, and is expected to track east, roughly along the I10 corridor through the afternoon. The front and associated precipitation shield will move east as well, as the low moves across area. The greatest potential for stronger storms will occur east of this low center as it tracks through, so generally along the I10 corridor. Latest forecast data suggests the center of this low will move offshore east of Jacksonville area toward 00z. As high pressure builds from the west Tonight, strong pressure gradient will exist across area between the departing low and advancing high. This will keep winds somewhat elevated Tonight, as skies clear from west to east. The gradient will weaken into the day Thursday, as skies remain clear.

Temperatures, will fall Tonight behind the front, with lows in the 40s. A significantly cooler day is expected for Thursday, with highs about 10 degrees below seasonal averages. In areas that were south of the front Today, highs Thursday will be about 20 degrees cooler than Today.

SHORT TERM . [Thursday Night through Friday] .

The low pressure center located off the Carolina coast will rapidly intensify while moving east northeastward into the Atlantic. High pressure will move in behind the low, centered in the upper midwest and building to the southeast into the Ohio and Tennessee Valleys. Winds will be calm and shift to be generally from the north overnight into Friday. Overnight low temperatures will be colder than average with temperatures near freezing for SE GA and the Suwannee Valley and mid 30s for the rest of NE FL and the coast. Widespread frost is expected and a freeze is possible for SE GA and the Suwannee Valley near sunrise with areas of to patchy frost expected for inland NE FL. High pressure to the north on Friday will keep the area dry with light winds from the northeast. High temperatures on Friday will be in the mid-to-upper 50s for SE GA and upper 50s to lower 60s for NE FL.

LONG TERM . [Saturday through Wednesday] .

High pressure will continue to dominate the weather pattern on Saturday with dry conditions expected. High temperatures on Saturday will warm into the lower 60s in SE GA and mid-to-upper 60s in NE FL. The next chance for rain will arrive on Sunday as a low pressure system moves from the Midwest towards the Mid- Atlantic, which will bring a trailing cold front across our area. The cold front will bring a chance of showers and thunderstorms to the area as it passes, and it will push offshore overnight Sunday into early Monday. High pressure will build again along the east coast following the passage of the front with surface flow generally from the northwest, which will keep the area dry and cool Monday afternoon through Wednesday. Temperatures will trend above average ahead of the front on Sunday and below average after it passes on Monday and Tuesday. Wednesday temperatures will return to near seasonable values.

Marine.

The high will build from the northwest then north Thursday night into Friday. The high will build toward the northeast Friday night through Saturday. The high will build to the east Saturday night as a cold front approaches from the northwest. The cold front will cross the area Sunday into Sunday night. The region will be between the exiting low to the east northeast and building high to the west northwest Monday into Tuesday.

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.
