Marine Weather and Tides
12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed.
10/9/2019 Updated the Marine Zones.
9/4/2019 Fixed the weather maps due to NOAA moving them.
7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports.

Area Forecast Discussion National Weather Service Jacksonville FL 1013 AM EDT Mon Jul 13 2020
No change to forecast thinking for today. A few storms popping up along I-75 about 3 p.m. then moving east toward the east coast.
PREV DISCUSSION [703 AM EDT].
NEAR TERM [Through Tonight].
Unseasonably dry air mass over the region that shut down convection on Sunday will get replaced with increasing moisture Today as shortwave energy drops into the region from the West and is expected to trigger at least Scattered late morning and afternoon storms moving from West to East across the region. Mostly sunny skies with a few high clouds at times this morning will still be enough to drive Max Temps into the lower to middle 90s area-wide as southwest flow increases to 10-15 mph ahead of the approaching shortwave. The Southwest surface flow off the Gulf of Mexico will increase dewpoints back into the lower to middle 70s which combined with daytime heating will push Heat Indices into the 102-106 range by early this afternoon, just below Heat Advisory criteria. Slightly faster movement to storms from West to East this afternoon will allow for a better chance for gusty winds in addition to locally heavy rainfall in the strongest storms but organized severe weather is not expected. The Southwest flow will push the heat all the way to the Atlc Beaches as the East Coast sea breeze front remains pinned along the coast. Diurnal storms will fade by sunset with muggy overnight lows in the mid/upper 70s in the southwest flow which may also develop some overnight showers and isolated storms along the Big Bend Region of NE Gomex which may push inland to the I-75 corridor of inland NE FL during the overnight hours.
SHORT TERM [Tuesday Through Wednesday].
Southwesterly flow during midweek will result in easterly onshore winds by midweek, with the area of high pressure being situated off to the east and northeast. Diurnal convection with scattered to numerous showers and thunderstorms developing primarily across the center of the forecast area, aligning with the troughing above. Daily high temperatures during this period are expected to reach into the lower to mid 90s with peak heat index values ranging between 100 - 110 degrees. Overnight low temperatures are expected to be in the lower to mid 70s for midweek.
LONG TERM [Thursday Through Sunday].
High pressure ridge extending from out of the northeast will lead to the prevailing flow shifting about from out of the west to becoming more out of the east. This onshore flow will result in daily diurnal convection associated with the sea breeze pressing inland. Temperatures for the end of the week and into the weekend are expected to be slightly above the climatological average.
AVIATION. [Through 12Z Tuesday]
No change in thinking with respect to Aviation products. Mostly VFR conditions at all fields with convection developing near I-75 around 20 utc and moving toward the east coast through 02 utc. Right now widely scattered enough to only warrant VCTS in the TAFs and will look at possible TEMPOs with the 18 utc package.
Trof axis down the SE US coastline will keep mainly offshore flow at 10-15 knots with seas 2-4 ft through mid-week with local onshore sea breezes along the coast. As the trof axis breaks down during the mid-week time frame, it will get replaced a weak High pressure ridge north of the waters and expect a more onshore east to southeast flow to develop by Thu/Fri time frame. No headlines.
Rip Currents: Low Risk of Rips continues in the offshore flow with surf/breakers in the 1-2 feet range through Tuesday.

NOTE: East coast views moved to GEOS-16. They are experimental and not well supported by NOAA so they may not be correct so be warned. This change required redoing a large amount of the GOES code. If the image you are expecting is not showing, please let me know. You may need to use the EDIT function to update your location.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
