242 pm cst Wed feb 20 2019
.Short term (tonight through Thursday night): the clearing
occurring today will end retreat by this evening as a weak coastal
trough sets up offshore and northeast flow over the water brings
low level moisture back into the area. Light showers will be most
likely over the gulf tonight and Thursday morning, but a few could
also move over the coast and a short distance inland. The trough
will fill on Thursday, with moisture lifting north as broader high
pressure takes over. Winds will veer from north and east to
southeast Thursday night. Look for low temperatures in the 50s
tonight, with a warming trend on Thursday taking high temps into
the upper 60s and lower 70s. Low temperatures Thursday night will
be warmer, in the lower 60s for may areas.

.Long term (Friday through Wednesday): highly amplified pattern
remains in place into Friday with large trough dropping southward
along the rockies and high pressure over the bahamas, keeping
south texas in southwesterly flow aloft. Friday will be dominated
then by modest southeast return flow as the coastal trough
dissipates, helping temperatures into the 80s. The h5 trough then
ejects across the central us, bringing along a modest cold front
Saturday morning. The front will move through mainly before peak
heating, so most of the area will see dry conditions. Areas right
along the coast may see some showers with the front, when it taps
better llvl moisture, but overall rainfall amounts remain
minimal. Much drier air expected behind the front Saturday, along
with some modest northwest flow may bring a threat for fire
behavior issues Saturday afternoon, mainly in the far western
valley. The front progresses well to the south initially into
Sunday morning, so most of the area will have a mild and mostly
sunny day. The front will again transition to a coastal trough
late Sunday night, bringing a return of overrunning clouds and
light rain drizzle conditions, likely from Monday evening through
Wednesday.

.Marine:
tonight through Thursday night: light to moderate north to
northeast winds and moderate seas will prevail tonight with a
coastal trough over the waters. The low pressure area will fill
Thursday and Thursday night as it is replaced by a broader area of
high pressure. Winds will veer to southeast Thursday night to
Friday.

Friday through Monday: modest southeast winds are expected ahead
of the next front on Friday, with winds reaching near 15 knots
during the afternoon. The front will sweep through Saturday, with
northwest winds around 15 knots expected. Winds will gradually
shift to the northeast on Sunday as coastal troughing begins to
develop. Winds and seas are forecast to remain modest into early
next week.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
