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.

Area Forecast Discussion National Weather Service Huntsville AL 802 AM CDT Tue Oct 27 2020
NEAR TERM. (Rest of Today) Issued at 802 AM CDT Tue Oct 27 2020
Low cloud deck over the area persists with moist low levels indicated on the 12Z sounding. Patchy fog is also noted, mainly on the ridges. Through the day, expect low clouds to remain with us north of the surface boundary to draped over north GA into centrAL. Perhaps a few thin spots or breaks take place during the afternoon, but not counting on it. Therefore, we have updated sky grids to increase coverage through the day based on this data. However, it appears precipitation is unlikely at this point this afternoon into early evening, so have removed that from the forecast.
SHORT TERM. (Tonight through Thursday) Issued at 300 AM CDT Tue Oct 27 2020
The main impacts in this forecast package will occur during the short-term period. A shortwave trough is forecast to track northwards across the area ahead of Hurricane Zeta tonight. At the same time, southerly flow in the low-levels will advect moisture into the region. Model soundings indicate deep moisture later tonight as the atmosphere quickly saturates. Additionally, the lingering surface boundary will aid in additional lifting. PW values will climb into the 2+ inch range in the tropical airmass. These values are above the maximum climatological values. Therefore, expect widespread heavy rainfall overnight into Wednesday. With the saturated atmosphere, model soundings indicate weak lapse rates around 5 c/km but there could be a few rumbles of thunder with some very weak elevated instability.
Still think there could be a break in the widespread rainfall late Wednesday morning into the afternoon. The shortwave trough and surface boundary shift to the north with the first round of strong moisture advection. Still expect showers will continue but there could be a brief reprieve in the intensity during the day on Wednesday.
Hurricane Zeta will make landfall along the LA/MS/AL Gulf Coast late Wednesday. Zeta will be racing to the northeast at this point as the closed low moves across TX. There is still some model uncertainty on the exact track and speed of the system but expect a second round of heavy rainfall late Wednesday night into Thursday morning as Zeta passes across or just to the south and east of the area. No severe weather impacts are forecast but there could be a few downed trees with the saturated soils and gradient winds from the weakening storm system. Storm total rainfall will range from around 2-3 inches with locally higher amounts possible. Fortunately, Zeta will be moving quickly and recent dry weather has lead to higher flash flood guidance values. Overall, do not expect any widespread flooding but could see some localized issues, mainly in areas of poor drainage.
A cold front sweeps across the area on Thursday as Zeta races to the northeast ahead of this boundary. PoPs will decrease from southwest to northeast on Thursday as colder air moves into the region.
LONG TERM. (Thursday night through Monday) Issued at 300 AM CDT Tue Oct 27 2020
The trough axis will shift to the east Thursday night. Temperatures will be noticeably cooler Friday with highs only in the mid 50s to low 60s (these values have been our morning lows over the last several days). Lows Friday night into Saturday morning will be in the low to mid 40s. Highs will moderate over the weekend into the 60s on both Saturday and Sunday. A cold front will bring in another round of cooler air Sunday night. Conditions will be dry with the frontal passage and temperatures will drop around 5-10 degrees on average to start the upcoming work week.
AVIATION. (For the 12Z TAFS through 12Z Wednesday morning) Issued at 622 AM CDT Tue Oct 27 2020
Low ceilings and visibilities at the terminals again this morning with low-level moisture remaining trapped below an impressive inversion. Expect similar conditions to the last few days with slow improvements in flight conditions throughout the day with VFR possible later this afternoon. Precipitation will move in late in the TAF cycle as moisture surges into the area with ceilings lowering again.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerous of sources and is presented automatically. 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.
