Synopsis for the middle texas coastal waters.. A mainly weak to moderate onshore flow will prevail through Tuesday. Isolated to scattered showers and Thunderstorms will continue to be possible during the later tonight through Tuesday night. Rain chances will then continue through the middle of the week as an upper level disturbance moves north of the area and a frontal boundary sinks southward across the state. Light to moderate easterly winds late week will become northeasterly over the weekend.

Discussion
Please see the discussion below for more details.

WidespreadVFR conditions will gradually transition to MVFR
conditions by the early morning hours across most of south texas.

However, the main issue will be an increasing coverage of showers
and thunderstorms across the western one-third of south texas,
generally west of highway 16. Will continue to advertise
thunderstorms through most of the TAF fcst pd for the laredo taf
site. Further east for the remainder of the TAF sites, rain
chances will be a bit lower and delayed until the early to mid
morning hours. Better chances for thunder will be during the aftn
across these particular locations as well. MVFR CIGS will
gradually transition toVFR CIGS by mid to late morning Tuesday
across most areas except laredo where MVFR CIGS will hold on even
into the aftn.

Previous discussion issued 313 pm cdt Mon sep 25 2017
short term (tonight through Tuesday night)
activity across the eastern half of the region will slowly dissipate
with the loss of daytime heating while better support dynamics
across the west may get things going out there by later this
evening. Hi-res guidance then shows more activity across the
southern coastal bend developing spreading farther inland through
the morning hours, basically a near repeat of activity we had
today.

The one big difference for Tuesday is the idea of widespread
convection across the brush country and rio grande plains
developing by early mid-afternoon. We continue with the higher
pops and threat of moderate to heavy rainfall across the western
quarter third of the region through Tuesday night Wednesday
morning. A lot of this depends on location and timing of the
shortwave troughs traversing through the region the next 36-48
hours as the longwave trough to our west sets up shop. It could
be a very fine line where some of these impulses clip the extreme
western portions of the region allowing for stronger storms to
develop with much higher QPF or they stay just far enough north to
produce minimal impacts. There has been a decent consensus of
bigger impacts for a few days now just to our north. This trend
hasn't changed too much but when looking at some smaller scale
processes it may not mean much.

With more rain and cloud cover temperatures will be tempered down a
bit but the humidity factor will remain ugly as pwats continue to
modify upward.

Long term (Wednesday through Monday)...

the period begins with an upper level closed low moving into the
four corners area and a series of upper level disturbances that will
provide instability across our region. The energy provided by the
disturbances, and high deep layer moisture filtering from the
pacific will continue the potential for moderate to heavy rainfall
through Wednesday and possibly into Thursday, especially for the
northwestern portion of the area. Eastern portions of the area will
see more of a diurnal pattern in the convection, but with very moist
area, seabreeze convection that develops could produce briefly heavy
rains. A weak cold front will move south reaching our area Friday
or Friday night. Temperatures are not expected to drop
significantly, but we will get slightly drier air into the
region... At least briefly. A return to a more zonal flow is expected
by the weekend. High temperatures will remain in the upper 80s along
the coast to around 90 inland. A drop on the low temperatures of a
couple of degrees is expected for the weekend after the passage of
the cold front. Otherwise, low temperatures will remain near normal
values.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

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.
