Marine Weather and Tides
8/26/2020 The 7 day forecast is taking about 5 seconds to load but it will eventually load. NOAA is still working on it.
8/18/2020 NOAA continues to have trouble. Wind guest will occasionally be left off graphs. I am working with NOAA to resolve the issue.
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.

UPDATE. Evening Update.
SHORT TERM. /Updated at 0745 PM CST Fri Nov 27 2020/
A low-amplitude perturbation continues to advance eastward across the Gulf Coast States with clusters of showers and embedded thunderstorms stretched across most of Central AL at this time. Thunderstorms have favored the south near the weak surface low where MUCAPE <750 J/kg and ~40 kts 0-6 km shear are in place per mesoanalysis. Winds remain light and variable, though should become more northerly behind the system gradually exiting the area to our east and south. This should begin to promote cool/dry advection in the north and northwest into tomorrow. Until then I've tweaked PoPs and temperatures in the near-term to account for observational trends. Generally speaking, PoPs were increased as a fairly large area of light rain remains in place across Alabama and into the TN Valley. Rainfall amounts outside of convection remains quite light. Trends indicate the departure of quality moisture and overall forcing such that decreasing rainfall intensity/coverage is forecast southeastward into tomorrow morning where only mentionable PoPs are along and south of I-85 through ~18z.
LONG TERM. /Updated at 0210 PM CST Fri Nov 27 2020/
Saturday night through Thursday.
A fast moving short wave trof will move out of the four corners region and track eastward towards Alabama Saturday night and Sunday. Saturday evening will be rain free across Central Alabama, with showers moving into the southwest counties between 3 and 6 AM Sunday. Strong forcing aloft will produce widespread showers and isolated thunderstorms during the day Sunday. Strong low level southerly flow on Sunday will advect 60+ surface dewpoints northward into areas south of I-85. 0-6km bulk shear is high enough for organized storms. There may be narrow window of time where instability may be high enough for stronger storms, but clouds and rain during the day Sunday will likely limit instability. The coldest air mass of the season will overspread Alabama Monday through Wednesday. Temperatures on Monday will stay steady or fall through the 40s. Lows in the 20s areawide Tuesday and Wednesday mornings. Another upper impulse will bring a chance of showers during the day Thursday.
Previous long-term discussion: /Updated at 405 AM CST Fri Nov 27 2020/ Saturday night through Wednesday.
A split jet stream pattern will feature a closed upper low across the Southern Plains and a shortwave diving southward toward the Upper Mississippi Valley. The closed low to our west will become an open wave, taking on a neutral to negative tilt as it interacts with the northern wave on Sunday morning. This will promote a deepening surface low over Alabama. An abundance of large-scale ascent and isentropic lift will overspread our region, leading to widespread rain and perhaps some thunder for the latter half of Sunday morning through early Sunday night.
A dry slot is expected to rapidly put an end to the rain by midnight Sunday night as a deepening area of low pressure moving toward the Mid-Atlantic states. Significant height falls and strong cold advection will take place Sunday night into Monday night as the northern shortwave absorbs the southern shortwave. Much of our forecast area is expected to remain in the 40s Monday afternoon with brisk northwest winds of 10-15 mph. The first widespread significant freeze will occur Tuesday morning with lows ranging from the lower 20s in our northwest to the upper 20s in our southeast. Temperatures will only rise into the 40s Tuesday afternoon as cold northwest flow continues. Temperatures should moderate for Wednesday as deep-layer westerly flow develops.
AVIATION. 00Z TAF Discussion.
A disturbance is passing across Central AL currently and is responsible for clusters of showers and embedded thunderstorms. Sfc observations paint a theme of MVFR weather, though SHRA/TSRA activity could bring periods of IFR conditions. For now, TSRA seems to only impact MGM/TOI through the next few hours. Lightning activity has dwindled farther north, so I've left out of TAFs (on the fence at EET). Northern terminals such as BHM/ASN/ANB could remain on the quieter side this evening with VFR/MVFR, but I've placed TEMPOs here for SHRA activity and MVFR the next few hours. This system will gradually move east overnight. A shift to light northerly winds is expected behind it but it will be mostly into tomorrow before we get out of the MVFR/IFR ceilings across the area as we clear from north to south. I suspect IFR ceilings will mostly impact MGM/TOI near the weak surface low tonight, but we'll monitor elsewhere.
Showers and embedded thunderstorms will overspread the area tonight, mainly for areas along and south of I-20. The rain will be confined to areas along and south of I-85 on Saturday as a weak cold moves through the area. Another rain event on Sunday. Much colder and drier Monday through Wednesday.

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.
