Discussion
Line of thunderstorms stretches now from around victoria through
corpus christi to nas kingsville. Convection will continue quickly
off to the east and should end for all of south texas by 8-9 am.

Cold front still west of cwa, but approaching northwest counties
at this time, and should move quickly across the area this
morning. Expect strong winds to develop behind the front.

Also see aviation section below.

Aviation
Convection ending over the next hour or so for vct and crp.VFR
conditions already occurring area wide, and will maintain this
through the rest of the period. Scattered mid level clouds
possible this afternoon. Gusty northwest winds develop for all
sites once cold front moves through this morning. Winds will
weaken late afternoon into tonight.

Prev discussion issued 412 am cdt Thu apr 18 2019
short term (today through Friday)...

convection continues moving across south texas ahead of a cold
front. The front lingers back west of eagle pass, but will
progress through the area through the morning. Good CAPE still
exists near the coast, but back where line of storms is currently
noted, CAPE is only about 1000-1500 j kg. Expect this line to hold
together at least across much of the area, but not looking for a
whole lot of strengthening as CAPE should continue to decrease
east. A few embedded updrafts could still produce severe hail.

Once the convection moves out of the region and the cold front
pushes through, things will quiet down significantly as high
pressure builds into the area. Northwesterly winds will increase
to moderate to strong levels this afternoon though, and with
decreasing rh values an elevated fire weather danger is expected
west. High temperatures today should return to the 80s despite the
cold front moving through. Will see a cooler night tonight though
with lows in the 50s thanks to dewpoints in the 40s. Northerly
flow continues on Friday with near normal temperatures mainly
in the 80s.

Long term (Friday night through Wednesday night)...

high pressure slides east of the region Friday night, bringing
return onshore flow in its wake. Southerly wind will increase late
Saturday and remain breezy through the first half of next week, as
moisture continues to increase. Shower thunderstorm chances hold
off until Monday night and Tuesday, as the next shortwave trough and
cold front look to hang up stall over northwest texas until toward
the end of the period at the earliest. Model timing of this system
is quite inconsistent so confidence in when thunderstorm chances are
highest is quite low at this time. Temperatures will be above
normal, although low temperatures will start off cool Friday and
Saturday nights, 50s over the brush country and the victoria area.

Thereafter, expect minima in the 60s to low 70s and maxima in the
80s (low 90s along the rio grande valley).

Marine...

thunderstorms will move offshore this morning producing gusty
wind. Small craft advisories remain in place for nearshore waters
and southern bays until early this morning and for offshore waters
through mid-day. A cold front will move offshore by mid to late
morning and shift winds to the north at moderate levels. Winds
will strengthen tonight and likely require scas once again. Winds
will subside on Friday. Fairly light wind is expected Friday
night into Saturday, as high pressure slides eastward and away
from the area. This will turn wind southerly onshore by Saturday
afternoon, with increasing wind likely Saturday night into Sunday.

A small craft advisory may be needed during this time, and
hazardous continues could continue through early next week, ahead
of the next cold front that has the potential to impact the waters
for the middle of next week.

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.
