.SHORT TERM [Today Through Friday]...

Showers are starting off in the eastern forecast area and some areas
of mist in the north. All this is expected to clear early this
morning giving way to scattered skies and a southeasterly breeze
throughout most of the day. This afternoon is expected to heat
enough to cause some diurnal convection to take hold but mainly
effect the area east of I-45 and I-10 and north. These afternoon
showers and possibly thunderstorms are expected to dissipate shortly
after sunset leaving behind overnight scattered skies and chances of
mist developing in the region. Friday will look similar with mainly
coastal showers in the afternoon as the upper level ridge build into
the area and takes hold. Winds will remain southerly and light with
the breeze along the coastal counties a little stronger in the
evening. Highs are expected to warm into the mid 90s with cooler
temperatures along the coast and higher in the northern counties.
Lows are cooling to the mid to upper 70s overall. 35

.LONG TERM [Friday Night Through Thursday]...

The upper level ridge remains over Texas through the weekend and
into the middle of next week continuing the mostly clear skies and
warm temperatures through the period. There will be a chance of
afternoon showers and thunderstorms that develop along the sea
breeze on Saturday. On Sunday, a very weak shortwave will move
across the area originating from Louisiana that slides across the
underside of the upper level ridge. This added upper level support
may help fuel the afternoon activity along the coast on Sunday, so
expect a bit more coverage on Sunday compared to Saturday. The
coverage of these afternoon showers will decrease Monday and
Tuesday, but an isolated shower along the coast will still be
possible. The pattern begins to change a bit by the middle of next
week as the upper level ridge begins to weaken across the Southern
Plains allowing for an upper level low to move into Oklahoma and
northern Texas on Wednesday and Thursday. This weakness aloft could
help fuel afternoon thunderstorms for not only along the coast, but
also further inland all the way up to Houston County. Still a ways
away, so don`t have anything more than 40 in the PoPs on Wednesday
or Thursday.

Temperatures through the period will be pretty much a persistence
forecast. High temperatures each day will be in the upper 80s to low
90s along the coast, mid to upper 90s further inland, and then up
into the upper 90s or even low 100s in the BCS area. The only hiccup
in these highs will be for areas along the coast where a well placed
thunderstorm may keep the high temperature lower than forecasted.
Overnight low temperatures will be in the mid 70s across most of the
inland areas through the period with areas along the coast only
getting down into the upper 70s to low 80s.ere.



.AVIATION [06Z TAF Issuance]...

A few showers in the eastern CWA and some areas of mist is
effecting the CXO area with in and out condition`s down to 1 mile.
Otherwise, VFR flying conditions at the TAF sites as the showers
dissipate and mist burns off shortly after sunrise. Southwesterly
winds and scattered skies will be seen in the forecast area. This
afternoon, areas of convection is expected but only expected to
effect CXO/IAH/HOU/SGR areas and some showers at LBX and chances
of showers in the UTS vicinity. Overnight, conditions will be VFR
with some chances of mist forming across the area but not
forecasted below MVFR. 35



Light winds and smooth seas through the day. A more onshore flow
will begin tonight mainly in the Matagorda area and then effecting
the entire coastal area through the weekend. Winds will gradually
strengthen over the weekend as well as seas building back up to 2ft,
with some intermittent times up to 3ft. Higher chances of coastal
showers return over the weekend and into next week. 35
