Update
Updated to include the 18z aviation discussion.

Aviation
Widespread ra will continue through the period with a
deterioration to ifr or worse at all terminals, although
restrictions may be bouncy. Did decide to prevail more pessimistic
cig vis given trends this morning. Winds will gradually back more
westerly then northerly after 14 00z with speeds and gusts
increasing through the end of the period.

Prev discussion (issued 357 am cst Thu dec 13 2018)
short term... Today through Friday night
gfs and ECMWF appear to be in good agreement this morning in the
short term. Southwest flow will be over arkansas this morning
ahead of an upper low over northwest texas. The upper low will
move southeast through texas tonight through Friday morning, then
into southwest louisiana before turning northeast Friday
afternoon. The upper low will really wind up heading into Friday.

The low will move through mississippi and alabama Friday night and
northerly flow will enter arkansas on the back side of the low.

Moisture is increasing ahead of the low pressure system.

Temperatures have been fairly steady or rising overnight. Radar
images show a large area of showers in oklahoma moving into western
arkansas. The best chance of thunderstorms will be across central
and southern sections. There is a marginal risk for severe
thunderstorms in the far south today as instability increases this
afternoon. Large hail is the main threat. Showers will continue
through the period as the surface low moves south of the state
Friday then east of the mississippi river. One to three inches of
rainfall is expected over the area through Friday night. Above
normal temperatures are expected today then cooler Friday.

Long term... Saturday through Wednesday
upper system responsible for the wet weather in the short term will
be located to the southeast of the state and pulling away from the
region as the period initiates. Models continue to wrap moisture
around the center of circulation early in the period with the ecmwf
remaining the slower solution. Slower speed continues to make a
little more sense as the system will be cut off from the prevailing
flow and as such, the forecast will be leaned in that direction.

However, models offer differing solutions once again towards the
middle of the week.

Showers will be possible very early Saturday over the east, and to a
lesser extent central sections, with higher pressure building in
behind the system. This higher pressure will bring several days of
dry weather to the area as upper ridging moves over the area.

Pattern also suggests temperatures moderating to above normal levels
as flow aloft will be of pacific origin.

Models are consistent in bringing another trough into the western
part of the nation early next week but that is about all they agree
on. GFS carves out an upper low in the base of the trough and drops
it into mexico while the ECMWF is much more progressive and moves
the trough through Wednesday accompanied by a few showers. As such,
added some minimal pops late in the period to account for the ecmwf
solution. Temperatures however will remain mild to close the period
out.

Lzk watches warnings advisories None.

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.
