Update
Frigid temperatures remain entrenched acrs southwest la and
southeast tx this morning, despite full sunshine. Cold 1040+ mb
high pres continues to build south, with gusty northerly winds
maintaining strong cold air advection acrs the region.

Temperatures have struggled to rise this morning, with readings
in the lower to middle 20s acrs the area. Also, visible stlt
shows frozen precip on the ground acrs parts of south central la
and this will also help to slow the temperature rise some. Made
some tweaks to hourly temperatures and dewpoints to reflect
observations and fcst trends. Also lowered aftn highs slightly
with temperatures not rising as quickly as anticipated. In
addition, extended the hard freeze warning and wind chill advisory
through 1 pm. Expect hard freeze conditions returning this evening
and another hard freeze warning will be issued with the aftn pkg.

for the 17 12z TAF issuance.

Aviation...

latest water vapor imagery shows that an upper level trough has
pushed east of the forecast area, and thus, clouds have also move
off to the south and east. Expect high pressure and a dry air mass
to continue to build into the region allowing for skies to remain
clear withVFR conditions. North winds today will be between 10
and 15 knots with occasional higher gusts. These winds will
subside to 5 knots or less after sunset or after 18 00z.

prev discussion... Issued 425 am cst Wed jan 17 2018
discussion...

short term... Today through Friday...

the main story in the short term period will be the arctic
airmass in place over the gulf coast.

Temperatures this morning have fallen into the teens to low 20s
across most of the region and could decrease a few more degrees
through sunrise. While winds have decreased overnight, even a
light wind in combination with the low temperatures will result in
wind chills in the teens to single digits. Winds are expected to
continue to decrease through the morning hours and temperatures
will increase so the current expiration time of 11 am for the wind
chill advisory continues to look good.

Hard freeze conditions are also expected to end by 11 am.

Temperatures are forecast to climb above 32 degrees around or
shortly after 12 pm. Portions of central louisiana that start off
cooler this morning may remain below freezing through closer to 1
or 2 pm this afternoon. Temperatures are expected to remain above
freezing for only a few hours this afternoon. However, the
combination of above freezing temperatures, low surface dewpoints,
and sunny skies should hopefully bring an end to any remaining
areas of ice.

Another hard freeze is expected tonight as clear skies and light
winds will result in ideal conditions for radiational cooling.

However, temperatures should recover more during the day on
Thursday with daytime highs in the low to mid 40s. Another freeze
is forecast for Friday morning, but the best chance for a hard
freeze should be confined mainly to the far NE portion of the cwa.

The arctic high pressure is forecast to shift east of the region
on Friday resulting in return flow developing and temperatures
climbing into the low to mid 50s.

Long term... Saturday through Tuesday...

no significant changes were made to the long term period of the
forecast. Return flow in advance of an approaching upper level
trough is expected to continue through the weekend resulting in
above average temperatures Saturday and Sunday. The upper level
trough and associated cold front is forecast to move across the
region late Sunday afternoon and evening bringing a chance for
showers and thunderstorms. This next front is not of canadian
origin therefore the air behind this front will not be as
extreme as we have had over the last several weeks. Therefore,
temperatures should return to near climatological normals by the
middle of next week.

Marine...

strong northerly winds and very rough seas will continue through
this morning. These northerly winds will result in low water
conditions across the inland lakes and bays during low tide later
this morning.

Winds are expected to gradually decrease through the afternoon,
but mariners with small craft should exercise caution through this
evening. Winds are forecast to shift to the east on Thursday and
southeast by Friday as high pressure moves east of the region. A
light to moderate onshore flow will then persist into the weekend.

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.
