Area Forecast Discussion National Weather Service Jacksonville FL 933 PM EDT Sun Jul 5 2020

UPDATE.

Diurnally enhanced band of tstorms has shifted well offshore of the local Atlantic coast with now just lingering showers/isolated storms drifting ENE across SE GA near a lifting trough axis. A surface low just to the SSW of Panama City (50-60 nm offshore) was drifting NNE, with yet another trough axis extending across the eastern GOMEX lifting NNE on the east side of this low. Convergence near this next trough axis will bring the best potential for nighttime showers and isolated storms across our Suwannee River Valley zones and near the I-75 corridor. 00z JAX RAOB continued to show high moisture content with PWAT over 2 inches across the area, but drier low/mid levels below 700 mb (roughly 10 kft agl). This drier air will create thinner cloud cover at times tonight, which, combined with saturated ground and light inland winds will favor periodic low stratus and patchy fog development across our eastern zones through the night.

Mild and muggy conditions will continue with lows in the to low to mid 70s under near calm winds inland to SSE to SSW toward the Atlantic 10 mph or less.

MARINE.

SSE 10-15 kts this evening will shift more SSW through sunrise with combined seas 3 ft or less. Waves of showers and t'storms will continue to impact the waters.

Rip Currents: Low to moderate rip current risk Monday.

PREV DISCUSSION [755 PM EDT].

Short Term. /through Thursday/ .

The region will be between high pressure to the east and an area of low pressure over the central gulf coast through Tonight. A trough of low pressure will extend east across forecast area this afternoon. To the south of the trough the flow across NE FL will be south southwest, with storms moving toward the northeast. To the north of the trough, across SE GA the flow will be from south southeast with storms generally moving from southeast to northwest. A few strong storms will be possible with gusty winds, and locally heavy downpours.

The low is expected to lift north Monday into the central gulf coast states, then move east across central GA Tuesday, then off the Carolina coast Wednesday. This feature will provide added moisture to the region as it passes nearby, as well as adding convergence with the associated troughing. The added moisture and convergence will result in increased precipitation chances Tuesday into Wednesday, especially over SE GA.

Low pressure area will move further to the northeast Thursday, but troughing will trail this system, producing enhanced chances for convection.

Temperatures this period will be near to slightly above normal.

Long Term. /Thursday night through Sunday/ .

The region will be between a trough of low pressure over the southeastern US and a ridge of high pressure to the south through the weekend. The region will also be in the base of an upper trough as well this period. The combination of instability from diurnal heating and upper trough, along with convergence due to sea breeze interactions and surface troughing will provide for above normal chances for convection.

Temperatures will trend a little above normal this period.

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.
