The hot weather will continue on Sunday, though some folks may get a break from the heat in the form of an afternoon thunderstorm. The highest rain chances will occur generally along and east of the Interstate 35 corridor, but all will see at least a slight chance of rain. High temperatures will approach triple digits once again, with heat indices well above 100.
An upper level ridge will build back across the region midweek, bringing some of the hottest weather so far to this summer. High temperatures will be in the mid 90s to around 100 degrees Monday and Tuesday and then will rise into the upper 90s to 105 degrees by Saturday. Heat index values will also steadily climb this week, likely exceeding 105 degrees across parts of North and Central Texas, and even in excess of 110 degrees by the end of the week and into Saturday.
