Area Forecast Discussion National Weather Service Jacksonville FL 225 AM EDT Thu Aug 13 2020
NEAR TERM [Through Tonight].
The region will be in an area of light upper level winds today due to an upper trough over the Mississippi and Tennessee Valleys and an upper ridge to the southeast. In the low to mid levels, high pressure will be centered near Bermuda, with the ridge axis extending across central Florida. The low level southwesterly flow will strengthen through the day as the ridging slides slowly northward. The very deep tropical moisture over the area will get jettisoned to the northeast before daybreak on Friday. Precipitable water values will fall from 2.0-2.2 inches today to 1.7-1.95 inches overnight. Scattered showers and storms are forecast to develop along the Gulf coast sea breeze in the early afternoon and push inland, meeting the east coast sea breeze in the late afternoon just west of I-95. Overall storm motion will be very slow, dictated mainly by the sea breeze and outflow boundaries. Locally heavy rainfall and gusty winds from wet microbursts are the main threats from storms. Highs will be in the lower 90s.
Convection will gradually dissipate during the evening hours. Predawn convection may increase in coverage over the northeast Gulf of Mexico and along the Nature Coast on Friday morning, with scattered coverage possibly moving into southern portions of the Suwannee Valley towards sunrise. Lows will be in the 70s.
SHORT TERM [Friday Through Saturday].
A low pressure system will develop as an upper level shortwave digs into the OH Valley Friday, with a surface frontal boundary developing across NC/TN. The low will continue to deepen as it pushes further SE into the TN Valley on Saturday, shifting the surface frontal boundary further S into W GA/SE AL, possibly reaching SE GA late Saturday Night. Ahead of the front, the area will continue to experience warm, muggy summertime conditions with enough moisture, heat and instability to get seabreeze storms going in the afternoon/evening with just a smidge more forcing from outflow from storms to our northwest along the front. This extra lift will likely lead to higher coverage over inland SE GA both Friday and Saturday. Moisture available will be a little lower than we've seen the last several days, hovering around 1.7-2.1", but will still be enough for some storms to produce heavy rainfall. With grounds already saturated in many spots from recent heavy rainfall, isolated flooding will be possible.
LONG TERM [Sunday Through Thursday].
The aforementioned front is forecast to move into SE GA on Sunday night and into NE FL Monday-Monday night. Behind the front, drier air will infiltrate the area, although only briefly. With a deep trough setting up over the eastern CONUS Tuesday through the remainder of the week, deep layer southwesterly flow will quickly bring a return of rich Gulf moisture to the region, setting us up for an active seabreeze pattern once again. Temperatures will be near to ever so slightly below normal, peaking in the upper 80s to low 90s in the afternoon and dipping into the low-mid 70s at night.
AVIATION. [Through 06Z Friday]
VFR conditions with light winds will prevail the rest of the night. Light southwest winds 5-10 knots will prevail on Thursday, with the east coast sea breeze pushing inland in the afternoon. Scattered to numerous showers and storms will develop and along the Gulf coast sea breeze in the early to mid afternoon, and push towards the east coast in the mid to late afternoon hours. Showers/storms will diminish in the evening with light winds and VFR conditions overnight.
A trough will remain situated just west of our GA waters through the weekend, keeping the axis of weak Atlantic ridging positioned across central FL, resulting in prevailing south-southwesterly winds during the next several days. Showers and thunderstorms will develop each afternoon over land and may impact the near shore waters during the late afternoon and evening hours, with scattered activity possible offshore during the overnight hours. The Atlantic sea breeze will develop each afternoon, with winds becoming onshore over the near shore waters, followed by southerly evening wind surges. Seas of 2-4 feet will prevail both near shore and offshore through early next week. Coverage of showers and thunderstorms may increase early next week as a frontal boundary stalls just to the west of the GA waters.
Rip Currents: SE GA: Low risk through Friday NE FL: Moderate risk through Friday
Weak winds aloft will continue today and tomorrow, keeping daytime dispersions low. Winds will increase Saturday as a low pressure system pushes into SE GA. Daily afternoon and evening showers and thunderstorms will bring periods of heavy rain, lightning, and occasional damaging wind gusts to the region. Fog will be possible in the mornings, especially in areas that received rainfall.

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.
