Area Forecast Discussion National Weather Service Jacksonville FL 733 PM EDT Sun Apr 5 2020

AVIATION. [Through 00Z Tuesday]

Rain dispersing throughout the region with an overall calming of winds. Some potential for lower cloud decks in the late evening and overnight, with early morning fog anticipated for Duval County sites and GNV. Fog is expected to disperse shortly after sunrise. Potential for mist at SSI early tomorrow morning as well, with SGJ expected to remain unobscured.

PREV DISCUSSION [712 PM EDT].

NEAR TERM [Through Tonight].

A weak surface trough stretches across the Southeastern US this evening, with an east coast seabreeze boundary making its way westward across the FL Peninsula and Srn GA. Isolated showers will dissipate over the next few hours as the seabreeze boundary races westward. By midnight, even the Ocala area should be done for the night. With increased soil moisture from this rain and light winds overnight, patchy fog may develop in the early morning hours. Otherwise, should be a quiet night with lows in the mid- upper 50s, low 60s along the immediate coastline.

SHORT TERM [Monday Through Tuesday].

Monday . Sfc high pressure around 1020 mb will initially be located off the GA/SC coast will drift southeast during the day. Model guidance shows mainly dry conditions with low level flow mainly east and southeast, with flow aloft northwest with subsidence overspreading the region in the wake of today's shortwave disturbance. While likely will not show much in the way of any rain chances, best moisture will be across the srn zones where PWATS of 1.25 inches is located, and some weak low level convergence may support a brief shower. Otherwise, we anticipate warmer highs than today with partly cloudy skies with highs mainly in the lower 80s though upper 70s at the coast.

Tuesday . Another shortwave disturbance will roll across the upper level ridge aloft of the area, developing a surface trough that will move through the Southern Appalachians and into the Mid- Atlantic. This trough, along with low-mid level isentropic ascent to its south is expected to allow shower development across central Georgia, which could spread into our southeast Georgia counties Tuesday afternoon and Tuesday night. Model MLCAPE values are <200 J/kg, so not expected much in terms of thunder/lightning with these storms. Temperatures will peak in the mid-upper 80s Tuesday, dipping to the mid 60s overnight.

LONG TERM [Wednesday Through Sunday].

Upper level ridging across the northern Gulf coast will flatten out mid-week as an upper low digs into the Great Lakes Region and another low from southern CA swings eastward into the Four Corners Region. Tuesday's surface trough will be pushed off to the east- southeast, dragging along the FL-GA state line Wednesday. Though this trough will exit Wednesday night, a cold front is expected to develop Thursday downstream of the Great Lakes UL low. This front will glide through the Southeastern US, connecting back to a developing area of low pressure downstream of the Four Corners UL low. The cold front is poised to move through our area of responsibility Friday, bringing colder temperatures to the area, but stalling out across central FL Friday night, keeping scattered showers in isolated thunderstorms in the forecast through the weekend.

MARINE.

Long period swells about 12-14 seconds from the east to northeast will continue to affect the area next few days. Swells appear to peak in height over the next 24 hrs or so, then diminish, with wave periods shortening by mid week at or below 10 seconds. SCA will likely continue into Monday for these elevated seas. Otherwise, high pressure ridge offshore to the northeast on Monday will slip southward through the mid week . with prevailing offshore flow Tuesday through Thursday. A cold front is forecast to move into the forecast area by Thursday night and Friday. Some risk for showers and isolated t-storms over area waters on Wed and again early Friday morning.

FIRE WEATHER.

Rainfall will begin to disperse later in the afternoon/evening and clear out overnight. There is a chance for showers Monday afternoon, with the highest chances for precipitation occuring in the vicinity of Marion county. Dispersion levels are expected to be higher than average on Monday for much of the forecast area, with minimum RH levels ranging between 35-45% for inland counties. Winds on Monday will out of the E-SE for NE Florida and along the coast and more out of the SE-S for inland Georgia, with windspeeds for inland areas ranging to about 5-10 mph and up to about 10-15 mph and gusts of 20+ mph for areas affected by the afternoon east coast sea breeze, affecting the coast and coastal adjacent counties.

HYDROLOGY.

The Altamaha River in SE GA remains elevated this weekend. The gauge at Baxley continues to trend down today and forecast to drop below flood stage Monday morning. Along the coastal areas, water levels are a bit elevated (up to about 1.2 ft MHHW) given the combination of light onshore flow, the upcoming full moon on 4/7, and east-northeast swell activity. Even so, no statements appear necessary at this time.

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.
