Synopsis for high island to matagorda ship channel out 60 nm.. Isolated showers and storms continue overnight over the coastal waters, expanding in coverage by morning. A weak to moderate onshore wind pattern will persist over the next several days, producing relatively low seas and smooth to slightly choppy conditions in the bays. Precipitation chances decrease by mid- week as high pressure begins to build into the region tomorrow.

Aviation [00z TAF issuance]
Band of showers from near high island to dkr and a second band
from near 66r to cll to grk. Outflow boundary squeezing in from
the northwest near cll. Wind shifting to the nnw with the ob.

Otherwise isolated storms should be the norm for a few more hours
then loss of heating ending the development.

OvernightVFR with the possible exception of some patchy fog at
cxo.

Tomorrow upper flow is more northwesterly and expecting more
redevelopment over the gulf waters with the upper low as it gets
dragged off into la. This may help sap the low level moisture over
setx and weaken the seabreeze development. For now will be
carrying vcsh vcts starting around 11z near gls shifting inland to
lbx 13z and then the metro hubs 16-18z. Confidence is low and
will refrain from any prob30 windows until confidence and
consensusgrows.

Short term
Short term and global models have done a poor job initializing
conditions today and showers and thunderstorms have been slow to
develop. Convective temperatures are in the middle 80's and this
threshold has been met. Upper level winds are also broadly
divergent so am a little perplexed as to why convection has not
developed. Think the texas tech WRF has initialized the best and
this model suggests that there will be development in the next
hour or so. Will maintain chance pops inland for this evening.

Shra tsra over the gulf will continue overnight and this should
impinge on the coast and will carry likely pops along the
immediate coast. Weak low pressure over the gulf has remained
disorganized and whatever is left of the low will likely get
gobbled up by a trough over the central plains ms delta on Sunday.

Pw values on Sunday remain between 1.90 and 2.25 inches.

Convective temperatures are in the lower 90's which looks
reachable so am expecting shra tsra to develop with heating. Upper
level winds still look favorable on Sunday before subsidence
kicks in Sunday night and Monday. 43

Long term
The upper level trough over the central us will shift east Sunday
night and upper level ridging over the western us will move back
into the area. Subsidence associated with the upper ridge will
bring drier conditions and much warmer temperatures through mid
week. The ridge breaks down a bit and retreats west Thu fri. A
weak front will slide into east texas on Thursday but pressure
rises behind the front don't look too impressive so it is unclear
if the front will make it all the way across SE tx or stall across
the area. The front will bring a renewed chance of precip wed
night into Friday. 850 mb temps cool a bit so would expect
slightly cooler daytime highs Thu fri. 43

Marine
High moisture within a continued unsettled maritime environment will
likely allow for the redevelopment of late Saturday through early
Sunday scattered showers and thunderstorms. High pressure over the
northern gulf will maintain a generally weak onshore wind field
through Sunday afternoon. A slight deepening of texas panhandle
pressure will create a tight enough onshore pressure gradient to
produce more moderate early work week southerlies. Caution level
winds are forecast late tomorrow through Monday morning. Overnight
Tuesday morning winds may also perk back up to around caution
criteria mainly due to the localized mix down of slightly stronger
mid level winds. Early week average sea heights will gradually pick
up by another foot or so, to 3 to 4 feet, but then fall back to
around 2 to 3 feet mid to late week. Mid to late week high pressure
at all levels will maintain weak onshore winds and low seas. 31
