Area Forecast Discussion National Weather Service Jacksonville FL 316 AM EST Wed Feb 19 2020

NEAR TERM [Through Tonight].

Upper level ridging centered between western Cuba and the Yucatan Peninsula will remain stationary through the day. The ridge will then flatten out tonight and begin to retrograde to the west overnight. Upper level energy will continue to stream eastward across the Southeast through tonight. At the surface, an area of low pressure was moving to the northeast to the north of Maine, with a surface cold front across north central Georgia. Strong high pressure diving southeast across the northern Plains will help nudge the weak frontal boundary southward into the area today. The boundary will then stall across north central Florida overnight.

Scattered showers were moving across interior southeast Georgia, and this is expected to continue through tonight. Mainly dry conditions are forecast south of I-10, except scattered showers are possible across Flagler County and southeast Marion County. Isolated to widely scattered light showers are possible across northeast Florida tonight in the low level northeasterly flow. Light northwest to northerly winds this morning will become northeasterly 10 to 15 mph late in the day along the coast as the frontal boundary shifts southward.

Highs today will be in the low to mid 70s across southeast Georgia and the upper 70s to mid 80s across northeast Florida. Overnight lows will be in the mid 40s to mid 50s across southeast Georgia, coolest near the Altamaha River, and the mid 50s to lower 60s across northeast Florida.

SHORT TERM [Thursday Through Friday].

On Thursday, showers will be widespread across the area as an area of low pressure moves east along a frontal boundary over northern Florida. Showers end from northwest to southeast on Friday as high pressure builds into the region and pushes the cold front south. Dry conditions, cooler temperatures and clearing skies are expected on Friday, however, a developing coastal trough may bring in coastal showers later in the day on Friday. A much colder airmass settles in dropping low temperatures Friday night to potentially below freezing over inland southeast Georgia and Suwannee Valley.

LONG TERM [Saturday Through Tuesday].

Surface high pressure over the southeastern US on Saturday moves off the eastern seaboard on Sunday keeping the weekend mainly dry. Rain returns on Monday into Tuesday as a low pressure system moves across the midwest and its associated fronts move through the southeastern US. Temperatures will go through a warming trend this weekend into early next week as the prevailing flow shifts to be southwesterly.

AVIATION. [Through 06Z Thursday]

VFR conditions to prevail until near daybreak when MVFR stratus is forecast to move into the area.

VFR conditions are forecast to prevail by the afternoon with northwest to north winds 5-10 knots. Winds will shift to the northeast behind the front, with ceilings lowering to MVFR/IFR by the end of the TAF period.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

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