From Brady Taylor:
Highs today will be back into the lower and middle 90s, with heat index values climbing into the upper 90s to near 100° yet again.
The stubborn High pressure dome to our north shifts eastward Wednesday into Thursday. Skies will feature a few more clouds and highs a bit lower in the upper 80s and low 90s.
Beginning Thursday, a series of weak disturbances (and potentially a weak front) may approach Central Texas to provide us with chances for rain and thunderstorms. Rain is by no means a guarantee any day, but the chances look to be highest on Friday with a 40% chance. Rain odds drop to 30% Saturday afternoon and 20% Sunday afternoon.
