Area Forecast Discussion National Weather Service Jacksonville FL 316 PM EDT Thu Oct 1 2020

NEAR TERM [Through Tonight].

Under surface high pressure, we've had mostly clear skies today, which has allowed temperatures to warm to around 80 across the area already. Late tonight/early Friday, a dry cold front will move through, bringing cooler temperatures for the area tomorrow. Ahead of this front, lows will be in the mid-upper 50s inland,low 60s along the Atlantic coast and St. Johns River.

SHORT TERM [Friday Through Saturday Night].

Friday . A dry cold front late tonight/early Friday morning, leading to cooler temperatures again and persisting dry conditions. Highs will range from the mid 70s in inland SE GA to low 80s along the NE FL coast and north-central FL. Overnight, temperatures will dip into the low 50s across inland SE GA, low- mid 60s in NE FL.

Saturday . A warm front will lift into central FL, bringing a return of chances for showers, mostly from St. Augustine southwestward to Ocala. Daytime temperatures will remain cool, in the 70s, then overnight lows will warm up with the return of the warm front, ranging from the upper 50s in SE GA, mid-upper 60s from Jacksonville southwestward to Gainesville.

LONG TERM [Sunday Through Thursday].

As the warm front continues to nudge northward into our area Sunday, more widespread chances for showers return, with isolated embedded thunderstorms across our southeastern zones. This front is expected to stall out Sunday night, then gradually weaken as it drifts south-southeastward through mid-week. This will lead to continued low-end chances (20-40%) through the end of the period. Temperatures will warm through the week, with highs back in the 80s by Wednesday and lows mostly in the 60s.

AVIATION. [Through 18Z Friday]

VFR conditions will continue through Friday. A secondary dry cold front will push across the area early Friday morning. North winds will increase to 10-15 knots with frontal passage.

MARINE.

Northerly winds will become northeasterly Friday night as surface high pressure shifts eastward and a warm front approaches from our south. Chances for showers return to our southern waters Saturday with the approach of that warm front, followed by more widespread chances on Sunday as the front moves into our area. Front should sink south and stall Monday, keeping scattered storms in the forecast through the end of the 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.
