Aviation... /issued for 12z tafs/
diurnal convection is expected to become more isolated along I-35
this afternoon...so tempo thunderstorms and rain groups were left out of the 12z
forecasts. Will continue the general trend of MVFR to borderline
IFR ceilings between the hours of 06z and 17z along I-35. A light wind
field is expected today except for areas where convective outflows
occur. Winds should increase and trend more southerly for Sunday
morning.

Short term (today through sunday)...
latest satellite images are showing two cyclonic areas near the
Texas coast. The one located over the la/Texas coast will push to the
northeast as an upper level trough axis over the Southern Plains
moves eastward. The other cyclonic feature will remain across
southern Texas for the next several days. Rich tropical moisture
will continue to push across the area through the weekend with
chances of rain expected along and east of Interstate 35. With
precipitable waters near 2 inches across the southeastern counties...expect
isolated heavy amounts of 1 to 2 inches.

This activity should come to an end with the loss of heating early
in the evening. Lingering moisture and marginal instability could
result in showers and thunderstorms Sunday afternoon mainly east
of Interstate 35. Highs for the weekend are expected to range from
the middle 90s across The Hill Country to the upper 90s across the
Rio Grande plains.

Long term (sunday night through friday)...
for the upcoming week...the subtropical ridge will build across
the Desert Southwest and expand eastward through Friday. A
weakness/inverted trough beneath the subtropical ridge will
linger around southern Texas coast through the period.
With precipitable water values returning to around 2 inches...will include slight
chances of rain for Monday and Tuesday with low chances of rain
for the remainder of the week mainly south of Highway 90.
