Area Forecast Discussion
National Weather Service Houston/Galveston TX
928 PM CDT Fri Aug 11 2017


Made a few adjustments to temps and cloud cover this evening, but
feel the current forecast is on track. Convection north of the
area is expected to weaken as it sags south. Will see an increase
in high cloudiness over the area tonight.

Heat index values ranged from 107 to 110 this aft generally along
and south of a CLL to SGR to HOU to GLS line. Expect a similar
afternoon tomorrow concerning the heat indices, so went ahead and
issues a heat advisory for Saturday across this area. 33


PREV DISCUSSION... /ISSUED Issued by National Weather Service CORPUS CHRISTI TX/


Scattered showers and thunderstorms continue moving inland along
the sea breeze this afternoon. Anticipate this convection to wane
this evening with the loss of daytime heating. Heat index values
remain high this afternoon as well, and a heat advisory remains in
effect into early this evening. Similarly warm temperatures and
high dewpoints are expected over the weekend, and additional heat
advisories may be needed for high heat index values over the

Upper level high pressure will predominate across the region
through the weekend and into the upcoming week. A weak upper level
disturbance moving down the eastern periphery may clip the
region, bringing more isolated to scattered convection, mainly
across the eastern zones tomorrow afternoon. The upper level ridge
will remain across the south central CONUS throughout the period,
though SE Texas will generally stay more under the eastern
periphery through the majority of the period. A few additional
weak disturbances rounding across the region, along with general
daytime sea breeze activity will bring slight chances for showers
and storms throughout the upcoming week. However, most locations
will remain dry and hot throughout the period.
