synopsis...

at 4 am, the cold front is marked by a band of showers and tstms
extending from roughly baton rouge to pecan island. A few stronger
storms have developed near the coast this morning, prompting the
issuance of a few significant weather advisories, mainly for
possible wind gusts of 30-40 mph.

The front is moving quickly east and should be exiting our
southeast zones by around 12z. Gusty northwesterly winds are noted
behind the front, bringing cooler air and lower dewpoints into
the region. Meanwhile, the upper low is currently located over ar
and continues to progress southeast acrs the lower ms valley per
the latest ua analysis and WV imagery. A trough axis extends
southwest from the low into northwestern la and east southeast tx,
with drier air spreading southeastward toward the area on the
backside of the trough.

discussion...

any showers or storms ongoing acrs southern la will come to an end
early this morning as a drier and cooler airmass filters into
the region. Clouds are expected to quickly clear out, leaving
mostly sunny skies for much of the day. Aftn highs will warm into
the lower to middle 70s, about 5-10 degrees cooler than the
normal late april maximums.

The progressive northwesterly flow over the area will bring
another shortwave toward the region on Friday, but this feature
is expected to be a little weaker than the one this morning. This
shortwave will also bring a reinforcing front through the area.

Forcing along the frontal boundary will be minimal as winds will
remain northerly. Thus, low level convergence and moisture will be
lacking to produce any meaningful shower chcs, with no more than
perhaps an isolated shower acrs central la where precip water
values will be near an inch and mean layer rh approaches 80
percent.

Dry and pleasant conditions can be expected through the weekend as
high pres settles over the region. Overnight lows are expected to
remain slightly below normal both Saturday and Sunday morning,
with temperatures in the 50s. Meanwhile, under mostly sunny to
partly cloudy skies, daytime temps will warm to near normal with
highs around 80 each aftn.

Low level winds will become more southeasterly late Sunday into
Monday as the sfc high moves east. This will result in a warming
trend along with an increase in relative humidities early next
week. The flow aloft will transition more southwesterly as a
trough enters the western states, and this will bring a return of
slt chc pops by Tuesday. Moisture will continue to increase and
deepen through the week, with precip water values climbing from
around an inch on Monday to nearly 1.7 inches by Wednesday. Rain
chcs will gradually increase each day as the trough over the west
slowly moves east, but the best chc for convection is not expected
until late in the week when another front approaches the area.

marine...

moderate offshore flow can be expected in the wake of a cold
front early this morning and exercise caution flags are in effect
for portions of the coastal waters this morning. Winds will
continue diminish through the day as high pres builds south into
the area. A few showers or thunderstorms can be expected over the
eastern coastal waters zones early this morning as the front moves
east of the area. A mostly light offshore flow is expected to
continue through the weekend. Winds will shift southeasterly by
late Sunday into early Monday as sfc high pres moves east.

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.
