Area Forecast Discussion National Weather Service Jacksonville FL 841 PM EDT Sat Jul 11 2020

NEAR TERM [Through Tonight]. Scattered convection will continue over ne Fl until around midnight as outflow boundaries trigger thunderstorms in a hot humid airmass. Expect even less coverage of storms expected on Sunday as dry air aloft over Georgia spreads se across ne Florida. Hot temperatures(mid/upper 90s) will continue on Sunday with lower dewpoints mixing to the surface in the afternoon. Slightly lower dewpoints will mean heat indices not quite as high as they reached today.

PREV DISCUSSION [735 PM EDT].

Short Term. /through Tuesday/ .

A northeast to southwest oriented trough of low pressure over SE GA, will sink south across NE FL Tonight into Sunday. As the the trough moves toward the southeast, the flow to the north of the axis will become more from the west northwest, bringing in drier air. As a result, convection not expected over inland SE GA this afternoon, while chances still exist across NE FL and along the coast of SE GA. The east coast sea breeze will contribute to the instability created by diurnal heating to keep activity going along the coast, with ample moisture across inland NE FL to keep potential in the forecast. With the trough axis extending across NE FL on Sunday, the drier air will push across SE GA, and interior NE FL, whereas moisture will still remain across area mainly south and east of a line from GNV to SGJ.

This trough will lift back to the northwest of the region Sunday night into Monday, and the troughing will remain in place through Tuesday. This will result in southwest flow across the area, and an increase in moisture. In addition a 500mb trough will be in place on Monday. The combination of instability from the upper trough and diurnal heating, along with increased moisture will yield above normal convective chances. The upper trough moves to the east on Tuesday with the trough to the northwest weakening.

Temperatures will continue above normal this period. The forecast is for slilghtly warmer weather on Sunday than Today, but with the expected drier air, dewpoints will be lower, leaving heat index values lower than Today.

Plan to cancel the heat advisory for Today with this issuance, as dewpoints have lowered, leaving values below criteria.

Long Term. /Tuesday night through Saturday/ .

A trough of low pressure will stretch northwest to southeast across forecast area Tuesday night into Wednesday, with high pressure to the northeast. This trough will be a focus for convective activity, with greater than normal chances expected.

This trough will weaken and sink to the southwest Thursday into Friday, as the high builds from the northeast. The high will build to the east on Saturday. This pattern will yield an onshore flow pattern. This will allow the east coast sea breeze to move well inland. While chances for mainly afternoon and evening convection will exist across forecast area, the best chance with this onshore pattern will be inland near the I75 corridor.

Temperatures will trend a little above normal this period.

AVIATION. [Through 00Z Monday] Isolated thunderstorms possible at ne Fl TAF sites til around 03z as evening storms linger. Expect VFR conditions to prevail overnight and on Sunday.

Marine.

A northeast to southwest oriented trough will extend along the coast this weekend, with high pressure to the east southeast. This trough will move back to the northwest Tuesday, with the high remaining to the southeast. The high will build to the northeast Wednesday, as a northwest to southeast oriented trough will lay across area. High pressure ridge will build from the northeast Friday into Saturday.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
