Short term
A slow moving frontal boundary slowly sagging southward into our
area will increase rain chances by this afternoon and continue
into the daytime hours on Tuesday. The front will struggle to push
completely though the area as an upper level trof over the ohio
valley slows and stalls along with a strong upper level ridge over
florida. The pattern will remain fairly locked throughout the
week with a significant cut off low sitting over the desert
southwest along with a west... Southwesterly flow aloft over
eastern texas and louisiana making it difficult to get a true
drying trend for the area of any significance. Moisture will
continue to ride along a frontal boundary from eastern texas to
the carolinas through midweek. The frontal boundary expected to
push into the northern gulf by Wednesday bringing a short period
of drier and cooler conditions by Thursday. Dry and warming
conditions expected on Friday as the boundary remains along the
northern gulf and basically just washes itself out.

Long term
A strong upper level trof will dig southeastward into the eastern
plains by Friday. Gulf moisture begins to stream northeastward
over the region by the end of the work week. A stronger cold
front expected to move southward into the ARKLATEX region by
Saturday increasing rain chances once again. Frontal boundary
expected to clear though the region by late Saturday night into
early Sunday morning bringing drier and cooler conditions for the
start of next week.

Aviation
Vfr for the most part but a few showers will begin to find their way
into the area over the next few days. Could have some tempo lowered
ceilings to around bkn008 accompanying the rainfall late tonight but
prevailing ceilings should remain at ovc030+.

Marine
A cold front will move to the coast by today into Tuesday and become
quasi-stationary. This will cause the gradient to tighten allowing
winds to rise to advisory conditions by the latter half of the week.

A second cold front moves to the coast by next weekend. Basically
conditions look to deteriorate over the marine areas via wind
conditions starting this weekend and lasting into at least the start
of the new week.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
