Discussion A warm front is slowly lifting north across the
region. To the north of the boundary temperatures remain in the
40s and 50s while southward is in the 70s to near 80.

The boundary is currently from grand chenier to
broussard youngsville to baton rouge. The warm front trails
southwest to a gulf low.

Tonight scattered showers and isolated storms will be possible,
however the main concern will be dense fog. While guidance had
indicated all day the vis should improve, it has not, but most
guidance indicates vis tonight, especially i-10 south, will tank.

Being that we haven't have had a great improvement through the
day, and sea fog continues to be visible in imagery, confidence
is very high on dense fog development.

Friday will start with the warm front still bisecting the region.

Overrunning will continue north of the boundary with a few showers
and possibly the storm to the south. Fog is expected to linger
along the coast.

Early Saturday the surface low will lift northeast across SE tx.

The warm sector will spread through north la and across a portion
of of NE tx. An upper disturbance and surface low will move across
the plains Saturday. This will continue to provide an onshore flow
and a fair amount of shear. The main question will be cape.

Farther inland instability will be greater hence the slight risk
from SPC in the east tx lakes and cenla northward.

A cooler and most importantly drier air mass will filter in behind
the front Saturday. Sun with highs in the 60s and 70s are expected
by Sunday, for a change.

Models diverge on the tue-thu scenario. Scattered showers are
expected, however there is a chance that most precip may remain
over the coastal waters.

Marine Sea fog will be the main concern through early Saturday
as a warm and moist air mass move in behind a warm front. Fog is
expected to be dense in the near shore waters and over the coastal
lakes and bays tonight and for most of Friday.

A cold front will move through Saturday clearing fog from from
west to east.

Winds behind the front may approach SCA criteria Sunday and
Monday, but mainly in the outer gulf waters.

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.
