Area Forecast Discussion National Weather Service Jacksonville FL 319 AM EDT Wed Jul 15 2020

NEAR TERM [Through Tonight].

Over the course of today initially southwesterly flow will back around to become more out of the east and northeast as the influence of high pressure ridging extending outwards from out of the northeast. Showers and storms will build throughout the day, mostly in conjunction with the diurnal sea breeze and fueled by outflow collisions which will be able to extend further due to weaker prevailing surface winds, and then . High temperatures today will range within the lower to mid 90s over northeast Florida and in the mid to upper 90s over southeast Georgia. Overnight low temperatures will range within the mid to upper 70s, with the warmest temps occuring along the coastline.


SHORT TERM [Thursday Through Friday].

High pressure ridge builds in north of the region with an onshore/breezy easterly flow at the coast and along with a drier airmass aloft with Precipitable Water Amounts (PWATs) around 1.5 inches or so will support less convection both days. This flow pattern will tend to shift any scattered showers and storms that develop to further inland areas of SE GA/NE FL with the best chances along the I-75 corridor during the afternoon/evening hours. Max Temps will be closer to normal values around 90 degrees along the coast/I-95 corridor and lower to middle 90s inland/I-75 corridor with Heat Indices peaking lower than today in the 100-105 degree range. Overnight lows in the lower/middle 70s inland and upper 70s/near 80 along the coast.

LONG TERM [Saturday Through Wednesday].

Longer range models suggesting a return to a wetter pattern, especially across NE FL as mid/upper level trof over the Bahamas will push westward into the FL Peninsula on Saturday with deep moisture and a return to more numerous showers/storms across NE FL with lesser convection over SE GA. Temps will be closer to normal values with Highs mainly in the lower 90s. The mid/upper level trof and moisture will track into the Gulf of Mexico for Sun/Mon/Tue with a slight reduction in rainfall chances but at least climo/scattered type afternoon showers/storms will continue with the best chances over inland areas as steering flow remains out of the East/Southeast as weak High Pressure ridge axis remains just north of the area across South GA. Temps continue near normal levels through the period. The cooler temps aloft at -7C/-8C at 500 mb will help to support greater instability and steeper lapse rates aloft and stronger storms with gusty winds are expected along with PWATs closer to 2 inches which will support locally heavy rainfall as well.

AVIATION. [Through 06Z Thursday]

Last remnants of overnight convection have dissipated making for VFR conditions throughout much of the region on into the early afternoon. Winds will initially be out of SW and then shift about to become out of the E and NE by the end of the day. Showers and storms will build throughout the day, mostly in conjunction with the diurnal sea breeze and fueled by outflow collisions. Thunderstorms are expected to clear from the coastal counties in the early evening and linger over inland areas later into the night.

MARINE.

High pressure will reside northeast of the waters through the end of the week with light winds becoming easterly and drier conditions offshore. An easterly wave will pass south our local waters late Friday into Saturday, with increasing shower and thunderstorm coverage expected this weekend.

Rip Currents:

FIRE WEATHER.

High pressure will move in from the northeast Today with southwest winds shifting to the east and scattered showers coverage and isolated storms coverage staying west of I-95. Minimum RH values will be in the 35-45 percent range over Southeast Georgia areas, but will stay above critical levels. Easterly, onshore flow will continue on Thursday with scattered showers and isolated storms over far inland areas with best chances along the I-75 corridor of Northeast Florida.

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.
