area forecast discussion
national weather service new orleans la
352 am cst Wed nov 14 2018

Short term
An upper level low centered over northeast texas will be pushing east-
northeast across arkansas today. This will finally bring an end to
the ongoing wet period. Radar imagery this morning shows the back
side of the rain shield to be just south of a houma to chalmette to
bay st louis line. Medium range and meso models all agree that the
rain will slowly by steadily shift east throughout the day with
slight differences on timing. The latest forecast is a blend of
those solutions. Post frontal air mass remains well entrenched and
the combination of overcast skies and strong cold air advection will
limit warming considerably. Highs will once again struggle to get
out of the mid 40s which is only a few degrees from the current temp
and 25 to 30 degrees below normal.

Long term
The remainder of this week and into the weekend looks to be a dry
forecast as surface high pressure builds in and upper level
troughing remains in place. Continental air mass will be bringing
the first light freeze of this fall season to the area Thursday
morning. The met and mav have tightened up on the differences but
the met is still the cooler of the 2. For tonight's lows, blended
the met and mav. Those numbers are fairly similar to previous
forecasts, so have upgraded the freeze watch to a warning for the
same parishes counties. As the surface ridge building in shifts to
just northeast of the area on Friday morning, will likely have cold
air drainage in northeastern portions of the CWA (from mcb to asd to
pql). Those areas may once again dip down to freeze or just below.

Temperatures will be moderating Friday and Saturday as the upper low
ejects northeast. The GFS and moreso ECMWF indicate that a weak
upper level inflection will bring a reinforcing cold front through
the CWA Sunday night. Rain chances are not very likely as it will be
a moisture starved boundary due to a lack of return flow ahead of it
and generally just slightly strengthen northerly surface flow.

Meffer

Aviation
Ceilings will slowly rise from ovc010 to ovc020 late in the day.

After ceilings go to ovc020, skc will not be far behind but may be
just after dark for most locations. This will occur from west to
east, and will try to time this accordingly. Some -ra and dz will
persist through about 18z along and east of a line from asd to msy.

This may be the case for most of the day at gpt. Some weak vis
restrictions down to around 3sm due to the dz or br will occur at
several sites through the morning hours.

Marine
Strong north winds will remain over the gulf waters today. These
conditions will likely stay through tonight and possibly even into
Thursday before easing. SCA flags have been extended through today
for the outer waters while caution conditions should hold over the
inner waters. Wind speeds will slowly ease through the remainder of
the week and should be back down to around 10kt by the end of the
week.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
