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.

NEAR TERM. (Tonight) Issued at 839 PM CST Thu Jan 21 2021
No major changes to the forecast with the evening update, only some minor tweaks to align with current observations. Low clouds associated with a cold front draped to the south of the forecast area will remain in place overnight. Any precip along the front should remain to our south with the exception of Cullman County. However, any rain that does fall will be light with at most a few hundredths of an inch in total. Given the cloud cover, temperatures will remain steady overnight with lows around sunrise in the upper 30s in southern middle Tennessee to around 40 farther south.
SHORT TERM. (Friday through Saturday night) Issued at 338 PM CST Thu Jan 21 2021
A few showers may linger into the morning hrs Fri for areas south of the TN River, or in closer proximity to the passing vorticity maxima to the SE, before a reinforcing cold front out of the OH Valley into the Midwest states moves swd thru the area going into the afternoon hrs. However, the influx of cooler/drier air may still be delayed enough where afternoon highs Fri will be able to climb into the lower 50s for most locations. Clearing skies should then allow for optimal radiational cooling Fri night, as a large dome of high pressure out of the Plains states builds SE into the Midwest/OH Valley regions. Early morning lows Sat look to fall mainly into the upper 20s, before temps again rebound into the lower 50s Sat afternoon, under mostly sunny skies.
LONG TERM. (Sunday through Wednesday) Issued at 338 PM CST Thu Jan 21 2021
Extended range guidance suggests that zonal flow aloft will be in place across the TN Valley at the beginning of the extended period, as the region will be to the north of a subtropical ridge centered over the northwest Caribbean Sea and to the east of a broad longwave trough encompassing the western CONUS. However, elevated warm air advection is predicted to strengthen throughout the day on Sunday as a mid-level trough crosses the southern Rockies, and this will support a northeastward expansion of light rain beginning during the late morning hours. As the mid-level trough begins to eject northeastward across the southern High Plains on Sunday evening, a warm front extending eastward from the system's surface cyclone will race northward through the local area, supporting a period of heavier rainfall and perhaps even some weak elevated convection (especially across northwest AL).
It appears as if the entire CWFA will be well within the warm sector of the cyclone shortly after sunrise on Monday morning, with strong southerly flow maintaining dewpoints in the u50s-l60s and increasing surface-based instability throughout the day. Showers and a few thunderstorms will become more numerous in coverage during the late morning hours as broad scale ascent increases downstream from the primary mid-level trough, but the greatest areal coverage should coincide with the passage of a surface trough that will sweep eastward during the late afternoon/early evening as the surface cyclone migrates eastward through the OH Valley. The northward advection of low-level moisture will likely result in sufficient surface-based instability by late afternoon for a cool season severe weather event, especially given the degree of vertical wind shear noted in forecast soundings, and this will be highlighted in the updated HWO.
Otherwise, a cold front will cross the region on Tuesday morning, ushering in a cooler/drier airmass of arctic origin. However, we will remain on the southern periphery of this airmass, and high temperatures are still expected to reach the l-m 50s on Tuesday with abundant sunshine. Yet another mid-level trough will eject northeastward out of the broader western CONUS longwave toward the end of the extended period, with renewed surface cyclogenesis across the northwestern Gulf of Mexico on Tuesday night. Light rain related to elevated warm advection could begin to spread back across the region from the southwest early Wednesday morning, and although it is not indicated in the current grids, a few sleet pellets may occur at the initial onset of precipitation. Scattered showers will continue across the area on Wednesday, with a few thunderstorms possible as well to the south of the TN River.
AVIATION. (For the 00Z TAFS through 00Z Friday evening) Issued at 510 PM CST Thu Jan 21 2021
Low level clouds associated with a system to our south will remain through the night into the morning tomorrow. As this system moves to the east, gradual ceiling improvement is expected starting from MVFR at the TAF onset and improving back to VFR after sunrise tomorrow. Light and variable winds will persist through the duration of this TAF cycle.

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.
