Update
For 00z tafs.

Near term (tonight)
issued at 250 pm cdt Mon mar 18 2019
temperatures have climbed into the lower to mid 50s under mainly
sunny skies. Some very thin high cloud cover has made its way
northward to near the tennessee river. Models continue to show this
moving northward this evening and overnight, before sliding southeast
of the area after midnight. Winds still remain fairly stout from the
north or northeast around 10 mph with higher gusts close to 20 mph.

Expect these winds to lighten up to around 5 to 10 mph early this
evening, before winds lighten further as the southern extent of an
area of high pressure slides southeast towards the area. Southern
alabama will likely be affected by thick enough high cloudiness to
keep temperatures warmer. However, think high clouds will be too thin
over northern alabama and southern middle tennessee to deter
radiational cooling much at all. Expect dewpoints currently in the
upper teens mid 20s to climb into the mid to upper 20s late tonight.

Good radiational cooling should allow temperatures to drop a few
degrees above dewpoint values into the upper 20s to lower 30s in
most locations, especially late this evening and overnight. Believe
temperatures will be at or below freezing for at least 3 hours
overnight into Tuesday morning. Thus, have issued a freeze warning
for all of northern alabama and portions of southern middle tennessee
from 1 am tonight through 9 am cdt on Tuesday.

Short term (Tuesday through Wednesday)
issued at 250 pm cdt Mon mar 18 2019
during the day on Tuesday the surface high to our north will slide
east into the ohio valley. Light winds and a bit warmer temperatures
are expected, due to developing easterly flow from the atlantic.

Upper 50s look reasonable after the cool start with abundant sunshine
expected on Tuesday. As warmer easterly flow continues on Tuesday
night, slightly more air looks to be advected into the region.

Isolated locations in some valley locations could still drop to
freezing briefly overnight into daybreak on Wednesday. However, most
locations should only drop into the mid 30s.

Stronger warm air advection is expected on Wednesday, as a front
pushes into eastern arkansas. Models continue to show precipitation
developing ahead of it and move this precipitation into northwestern
alabama in the evening hours. Decent lift and moisture convergence is
shown with most models. This should be able to produce around 1 4 of
an inch of rainfall across the area before it moves east of the area
Thursday morning. Highs in the lower 60s or bit higher look
reasonable despite rainfall and cloud cover.

Long term (Thursday through Sunday)
issued at 250 pm cdt Mon mar 18 2019
a drier and even warmer trend is shown by models Thursday through the
weekend, as a very strong area of high pressure builds behind the
departed front during this timeframe. Highs in the mid 60s to lower
70s look reasonable. A better chance of rain returns ahead of a
potent system late Sunday into early next week. Some thunderstorms
could be a bit stronger with this activity on Monday.

Aviation (for the 00z tafs through 00z Tuesday evening)
issued at 621 pm cdt Mon mar 18 2019
vfr conditions will prevail at the kmsl and khsv terminals. Other
than some passing high clouds, skies will remain mostly clear. Winds
will lessen overnight and then increase from the east after 15z.

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.
