Discussion
For the 01 22 18 1200 utc TAF package.

Aviation
Pre-frontal convection continues to push east through central and
southwest la, with the cdfnt quickly catching up from the west.

Forecast package was constructed using a blend of radar satellite
trends and short term hi-res guidance, basically ending convection
kaex-klch westward and timing the onset at the acadiana terminals.

An hour or so of ifr MVFR CIGS will follow the end of convection,
with a subsequent lifting cig clearing sky and increase in nw
winds with the passage of the cdfnt.VFR is expected to prevail
all sites by this afternoon and continue through the remainder of
the forecast period.

Prev discussion issued 440 am cst Mon jan 22 2018
synopsis...

an extensive band of showers and thunderstorms, some of which have
been strong early this morning, is progressing east acrs the area.

This band is occurring along a pre-frontal trough that extends
from central la southwest to near galveston. The actual front
just trails the main band of convection, and is located from near
el dorado, ar to toledo bend reservoir to galveston bay. Cooler
temperatures follow behind the front along with a sharp drop in
dewpoints.

Convection was being aided by good divergence aloft southeast of a
large upper level low pres system over ks. Latest ua analysis and
wv imagery show drier air over tx. A strong 130 kt jet streak
transiting the base of the trough is helping accelerate the system
eastward early this morning.

24
discussion...

the front will progress rapidly eastward this morning, and
showers tstms should exit the eastern zones early this aftn. Much
drier air will spread into the region today. While temperatures
may cool briefly in the wake of the front, they will rebound into
the middle 60s to lower 70s as skies clear through the day.

Dry and more seasonable conditions are expected through Thursday.

Skies will be mostly sunny with highs around 60 each day, while
nighttime lows will run slightly below normal from the middle 30s
to around 40.

A progressive pattern will be in place through the week. Sfc high
pres will slide east by late Thursday into Friday, causing
temperatures to moderate and low level moisture to increase by
Friday into Saturday. Another shortwave trough will cross the
rockies late in the week, with sfc low pres developing over the
high plains. Strengthening southerly flow and increasing lift in
advance of this system will bring a chc of showers tstms on
Friday, with chcs increasing through Saturday as a front moves
into the area. High pres building in behind the front on Sunday
will bring drier weather, with cooler temperatures expected to
return Sunday into Monday.

marine...

a cold front will move east across the coastal waters this
morning, exiting the eastern waters by early afternoon. Ahead of
the front, areas of dense sea fog, along with scattered showers
and a few thunderstorms, can be expected. Areas of sea fog will
come to an end from west to east with the passage of the front.

Moderate offshore flow will develop in the wake of the front today and
continue through Wednesday night. Winds are expected to
strengthen enough tonight to warrant exercise caution flags over
the outer coastal waters east of cameron. By Thursday and Friday,
high pressure will shift east of the region, with moderate east
to southeast winds developing by Thursday and Friday.

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.
