From Brady Taylor:
A weak front early next week may provide Central Texas with our next chance for scattered rain and milder temperatures, but before we see the prospects for rain go up, we'll have to deal with heat and humidity through the weekend.
High temperatures Friday and Saturday will hover near 100° under mostly sunny skies. Heat indices, or feels like readings, will range from 102° to 105°. Morning lows will drop only into the middle and upper 70s with a few clouds early.
Clouds will make a slow return Sunday which may help to cool temperatures off a degree or two into the upper 90s. This signals change in advance of the arriving front early next week.
Rain chances Monday are near 30% and those chances will stay at 20% through Tuesday morning. It's looking more likely that the front will clear the area by Tuesday afternoon. As northeasterly winds begin to pick up, temperatures will slightly cool off into the middle 90s Tuesday and Wednesday.
