Houston weather: Hot, showery pattern underway

Beginning Sunday and continuing through all of next week, look for hot and humid summer air with highs in the mid to upper 90s. The outlook is a bit random with a daily round of afternoon showers and storms expected, but with periods of hot sunshine in between. Our extended models are very mixed with timing and coverage of rain, but isolated afternoon storms make sense in this pattern. Also, heat index values could reach 105 each day next week.
