Discussion
Regional 88ds show the bulk of the precipitation which developed
earlier today has moved off into the gulf with just a few showers
now noted along the coast over swrn la. Water vapor imagery shows
drier air moving into the region from the north which is
corroborated by regional 00z soundings as much lower pwat mean rh
values are noted to our north. All of this spells a trend in
overnight pops of slim none across most of the NRN half to small
chances closer to the coast... To much higher over the coastal
waters. As expected, this also agrees with latest short-term
high-res runs as well.

Elsewhere, just minor tweaks at most per latest obs trends. Update
out shortly.

for 00z TAF issuance.

Aviation...

local 88ds continue to show quite a bit of convection covering the
srn 1 2 of the forecast area, possibly impacting the srn
terminals... However as this activity is diurnal in nature, expect
it to diminish over the next few hours with loss of heating.

Forecast time-height sections not indicating much boundary layer
moisture through the overnight hours so not expecting any fog at
this time. Tomorrow appears to be a repeat of today with good
moisture closer to the coast along with a weak shortwave or
weakness aloft and daytime heating.

weather map showing weakening frontal boundary across SE tx S la
this afternoon, likely along the i-10 corridor. Showers and
thunderstorms have increased in coverage over the last couple of
hours across SE tx SW la, with scattered coverage over the coastal
waters. This was expected with continued consistence from the
hrrr guidance this morning and afternoon. The convection expected
to continue through sunset and diminish this evening after the
loss of daytime heating.

The front is expected to slowly dissipate with a predominate
southeast flow resuming across the region by Tuesday, bringing
with it increased gulf moisture and higher chances of showers and
thunderstorms. The best chances for showers and thunderstorms
expected Wednesday through Friday as a weak shortwave aloft
enhances lift within our region already saturated with moisture
moving in from the gulf.

By Friday evening into the weekend, high pressure with slightly
drier air aloft is expected to diminish shower and thunderstorm
chances to near ~20% for 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.
