Synopsis.. A weak pressure pattern is in place over the local waters and will continue through the upcoming weekend as abundant tropical moisture persists over our region, with waves of showers and Thunderstorms each afternoon and evening. Meanwhile, weak low pressure developing east of the gulf stream waters off the carolina coast will slowly organize as it moves northward on Friday and then northeastward off the new england coast this weekend. High pressure will then build to the north over new england as the low exits northeast the north atlantic waters with winds becoming more onshore by early next week.

Area Forecast Discussion National Weather Service Jacksonville FL 200 PM EDT Thu Sep 16 2021

AVIATION. [Through 18Z Friday]

Heavy downpours and embedded thunderstorms will impact JAX and CRG through the late afternoon hours, with periods of IFR visibilities and brief wind gusts up to 25 knots expected during heavier downpours. Activity will likely spread across the SGJ and VQQ terminals after 20Z, where periods of MVFR to IFR visibilities and briefly gusty winds will be possible through around 00Z. Showers and thunderstorms should reach the SSI terminal after 21Z, where periods of MVFR to IFR visibilities and briefly gusty winds will be possible during heavier downpours. Confidence is lower for impacts to the GNV terminal through early this evening, but activity may expand westward towards the I-75 corridor late this afternoon, and we included a TEMPO group for briefly gusty winds and MVFR conditions at GNV through 00Z. Activity at GNV and SSI may linger through the early evening hours. Outside of thunderstorm activity, east to southeasterly winds will be sustained at 10-15 knots at the coastal terminals, while inland winds will be more variable and generally sustained in the 5-10 knot range. Sustained surface winds will then subside to around 5 knots or less once thunderstorm activity moves offshore by 03Z tonight. Periods of MVFR ceilings and isolated showers will then prevail overnight.

PREV DISCUSSION [1129 AM EDT].

Near Term. /through Friday/ .

Low pressure will move to the northeast Today. Remnants of slow moving Nicholas will continue over Louisiana Today, with a warm front extending east from it. Troughing will extend from the low to the northeast, to this warm frontal boundary, yielding an extended frontal zone. Early in the day, expect the best rainfall coverage along and north of the frontal zone across SE GA, but coverage and intensity of the convection will increase in the afternoon, especially in the warm sector across NE FL.

While convective coverage will decrease overnight with the loss of diurnal heating, the presence of the frontal zone will keep a few showers around.

The low to the northeast will continue to track north northeast Friday, while the remnants of Nicholas to the west will move little. Moisture will continue to move east across the region along the lingering frontal zone, yielding another day with higher convective coverage. The frontal zone is expected to move a little north during the day, which will help bump temperatures up.

Temperatures will trend a little below normal Today, then near normal for Friday.

Short Term. /Friday night through Sunday night/ .

High pressure will build to the north this period, with an inverted trough developing over forecast area. Ample moisture will remain in place this period, leading to a period of above normal precipitation chances.

Temperatures are expected to trend near normal this period.

Long Term. /Monday through Wednesday/ .

High pressure will build to the northeast this period, leading to a prolonged stretch of onshore flow. Moisture will remain across area, so above normal precipitation chances to continue.

Temperatures will trend near to a little below normal this period.

MARINE.

A weak pressure pattern will prevail across our local waters through the upcoming weekend as abundant tropical moisture persists over our region, resulting in periodic waves of showers and thunderstorms. Scattered activity this morning will likely become widespread by late this afternoon and this evening. Meanwhile, weak low pressure developing east of the Gulf Stream waters off the Carolina coast will gradually organize as it pivots northward on Friday and then northeastward off the New England coast this weekend. Seas of 2-4 feet will prevail across our local waters through the weekend. High pressure will then build over New England as this potential tropical cyclone accelerates towards Newfoundland, resulting in a slight increase in onshore winds by early next week.

Rip Currents: A lingering easterly ocean swell will keep a moderate rip current risk in place at all area beaches through at least Friday.

FIRE WEATHER.

Light surface and transport winds will result in low daytime smoke dispersion values during the next few days nearly area-wide.

HYDROLOGY.

Minor flooding continues along lower portions of the Santa Fe River near the Three Rivers Estates gauge.
