Discussion
Note aviation discussion below with regard to the 00z tafs.

Aviation
A transition fromVFR to predominate MVFR expected overnight.

Isolated/scattered showers are expected to develop Friday morning
with isolated/scattered showers and thunderstorms Friday
afternoon/early evening mainly east of u.S. 281. Some storms may
become strong mainly north of u.S. 181. Breezy surface conditions
this evening will transition to generally light overnight. Non-
convective llws conditions may occur mainly north of u.S. 181
during the 09-12z Friday period. Moderate/breezy south flow
anticipated mid morning/afternoon Friday generally east of u.S.

281.

Previous discussion /issued 420 pm cdt Thu mar 23 2017/
short term (tonight through Friday night)...

we continue the wind advisory across the southern coastal bend
through the remainder of the afternoon hours as we continue to mix
upward of 2-3kft. This is where kcrp VWP are showing 30 to 35 knots
of momentum that will remain in place much of the night and into
tomorrow. As the evening wears on we lose the deeper mixing which
allows the gusts to drop off but we keep a breezy southeasterly wind
in place through the overnight hours. Not expecting much in the way
of fog developing with the stronger turbulent mixing taking place.

Tomorrow's cold front is still expected to push into the region by
mid/late morning but lose steam as it does. Hi-res guidance/cams
continue to show a broken line of showers and thunder progress east-
southeastward from the san antonio area. We have increased the pops
across the northern coastal bend and victoria crossroads where the
better moisture profile is expected and where some better surfacing
forcing my occur. CAPE forecasts still show less than 1500 j/kg
across our eastern zones but the shear profile is better with nearly
40 knots of deep layer shear in place. Sherbs3 parameter is
indicating the potential for a stronger line of storms, high
shear/low CAPE setup, across our interior and northern zones so it
is something to watch out for, but we are not sounding the alarms
for severe convection. Strong winds look to be the main hazard from
these storms.

Front doesn't look to push all the way through our region tomorrow
but rather get hung up by the stronger southerly/onshore flow
somewhere across the interior/brush country. Mid-level troughing may
have enough of a push by late Friday night to nudge the front closer
to the coast but then it loses all its upper level support and just
stalls out.

Long term (Saturday through Thursday)...

very active pattern continues with numerous upper level disturbances
tracking across the conus. The first disturbance will be exiting the
area at the onset of the longterm period with drier air filling in
behind it on Saturday. The next disturbance is close on its heels,
passing north of us on Sunday and Sunday night. With the more
northerly position and a lack of moisture over the region, will
expect this system to not bring rain chances, however an increase in
wind speeds will be likely. Moisture will begin increasing into the
area Tuesday into Wednesday ahead of the next upper disturbance. Will
remain pretty conservative with pops for this period as progged
moisture levels still limited... GFS indicating only about 1.5" pwat.

After the mid-week system much drier air should settle in.

Temperatures continue above normal through the week despite weak
boundaries associated with the upper level disturbances. Highs will
be mainly in the upper 80s and lower 90s... With Sunday being the
warmest day of the period with highs possibly in the mid 90s west.

Low temperatures will be mainly the mid and upper 60s.

Marine...

sca conditions are expected to continue to commence across all
middle texas coastal waters through tonight, excluding the northern
bays and waterways. Winds and seas begin to decrease/subside by
Friday morning nearshore but the offshore waters may continue to see
strong onshore flow. The SCA may need to be extended through much of
Friday over the offshore waters.

Periods of scec to near SCA conditions will continue through the
weekend and into next week as approaching disturbances increase the
pressure gradient.

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.
