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.

SHORT TERM. /Updated at 0327 AM CDT Sat Jul 04 2020/
Today through Sunday.
The 4th of July will be marked by plenty of heat and humidity with a chance of afternoon storms. Daytime heating will be the main trigger for storms today. The better chances for rain today will be across the far southwest and northeast counties. A weak upper low over southeast Louisiana will bring better lift for coastal convection which will extend northward into southwest Alabama. A weak upper disturbance will track westward across northern Georgia and into northeast Alabama this afternoon as the upper flow remains out of the east. Similar to yesterday, storms will be moving from east to west. Steep low level lapse rates and SBCAPE values near 2500 J/kg this afternoon will be sufficient for a few strong storms with wind gusts of 35 to 45 mph. The convective activity will diminish in areal coverage and intensity early this evening with only isolated showers and thunderstorms expected by 9 PM. The rain should be gone by midnight. Some big changes to Sunday forecast as models now show an intrusion of drier mid level air from Georgia. This will keep higher rain chances confined to the southwest counties with pops around 60 percent, with 30-40 percent rain chances elsewhere. Temperatures will be on the warm side again today with highs in the lower 90s and heat indices near 100 degrees. A slight cool down on Sunday.
LONG TERM. /Updated at 0327 AM CDT Sat Jul 04 2020/
Sunday night through Friday.
A warm/moist air mass will build in across the area Sunday night and continue through most of the upcoming week. PWATs are forecast to be in the 2-2.2" range, which is on the upper end of climatology for this time of year. Couple this with a persistent weak upper level low, that while becoming more broad and diffuse, will likely provide enough forcing to support more widespread showers/thunderstorms during the afternoons. I've trended thunderstorm chances up to 90% for Monday, then to 80% Tuesday and Wednesday (mainly in the afternoons). Overnight periods will see a decrease in coverage, but I wouldn't be surprised to see at least some shower activity linger through the night on Monday and Tuesday. With the higher rain chances, we're likely to see a smaller diurnal swing in temperatures with highs in the mid to upper 80s and lows in the low to mid 70s.
Models continue to hint at a pattern change late in the week, though guidance hasn't shown much temporal consistency in when that would take place. The ridging to our west becomes more amplified, pushing the upper level low that will be over us slightly more eastward into Southern GA late Wednesday through Thursday. If this takes place as guidance suggests, it would put us in the periphery of the high pressure, leading to at least some subsidence and a slight decrease in PoPs. With the decrease in rain chances, unfortunately, we'll be looking a slight warming trend towards Friday. Depending on how the temps/dewpoints trend by the end of the week, we could see a return of afternoon highs in the upper 80s to low 90s and heat indices reaching/exceeding 100 degrees.
AVIATION. 06Z TAF Discussion.
Convection has generally ended for the terminals. With all of the convection and ample low level moisture, will mention some patchy fog for pre-dawn hours. We still have lots of lingering mid/upper cloudiness around and could see some stratus in the south near TOI toward sunrise. Another round of convection is expected on Saturday with plenty of moisture available with afternoon heating. Also, we have a lingering boundary across the southern part of Alabama. Although we should see at the least some scattered convection across most of Central Alabama, the southern areas closer to MGM/TOI should have the best chances and could last further into Saturday evening there.
The warm/moist airmass will also continue to be in place this weekend and into the early part of next week. Rain/thunderstorm chances increase for the first half of next week. Min RHs will be in the 50-60% range through Sunday, rising to 60-80% for next week.

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.
