From Rusty Garrett:
A Heat Advisory is in effect until 8pm Saturday for most of Central Texas. The heat index, or feels like temperature, should be near or exceeding 105° during peak heating hours. Be sure to stay very well hydrated and take cooling breaks if involved in outdoor plans.
The upper-level ridge of high pressure over the center of the country will weaken slightly this weekend as a disturbance pushes into South Texas. Very low rain chances are possible Saturday afternoon at about 10%, with most, if not all locations staying hot and humid. Highs Saturday should be in the mid to upper 90s. Slightly better rain odds should be in place Sunday at about a 20% coverage.
Seasonably hot conditions are expected to persist next week as the month of August nears, with highs remaining in the upper 90s and lower 100s under mostly sunny skies. Overnight lows should remain seasonably warm in the mid to upper 70s. Another Heat Advisory may be needed by the middle and end of next week, as heat index values should once again be near to or exceed 105°!
