Update

Lowered Tonight's lows another one to 2 degrees as temperatures are quickly cooling into the mid 50s north and west of downtown Jacksonville under clear skies and very light to calm winds. So mid to upper 40s will be the expected lows for SE GA west of I-95 and into the Suwannee Valley, areas west of Jacksonville along I-10 with low 50s elsewhere west of the St Johns river and mid to upper 50s into downtown Jacksonville and along I-95 in NE FL with low 60s at the immediate coast.

Very light winds remain over inland NE FL 4-8 mph and 5-10 mph along the coast/St Johns river which will persist through sunrise.

Near Term

Main Highlights through Tonight:

- Coastal & Marine Hazards Continue with high rip current risk, rough surf, beach erosion, and minor tidal flooding during high tide

- Lows in the 40s over inland SE GA/inland North FL again tonight

Northeast flow remains in place through tonight with a very dry air mass in place aloft (PWATs less than 0.5 inches). This will continue clear skies inland and periods of strato-cu clouds pushing onshore through the NE FL Atlantic Coastal counties before dissipating over the St. Johns River Basin to the south of JAX. Temps still slightly below normal with highs in the mid/upper 70s inland this afternoon and lower 70s along the Atlantic Coast. Low temps under clear skies and light north winds will fall into the 40s again over inland SE GA and inland North FL to the west of JAX along the I-10 corridor and down into the Suwannee Valley, with 50s expected elsewhere for coastal SE GA and the rest of inland NE FL, and lower 60s for coastal NE FL in the onshore flow. Breezy NE winds this afternoon generally around 15 mph with gusts to 25 mph along the Atlantic Coastal Counties and 10-15G20 mph over inland areas. Significant fog is not expected due to the dry air mass and light N-NE winds in place. Main hazards in the near term will continue to be coastal in nature with a high risk of rip currents, rough surf and minor tidal flooding along the St. Johns River Basin.

Short Term

Main Highlights This Period: Wednesday through Thursday night

- Coastal flooding expected due to onshore flow, along with continued high risk for rip currents

Elevated onshore flow pattern will continue through this period, due to high pressure to the north northwest, and low pressure to the northeast. It is expected to be dry this period. With a cooler and drier airmass in place, temperatures will continue to trend below average.
