Sunday’s forecast
A quiet and warm morning is expected across the Houston metro area as lows hover near 80 degrees. That’s significantly warmer than the average for mid-September, as lows should be closer to 72 degrees.
Temperatures will heat up quickly, likely reaching 90 degrees as early as 11 a.m. Then by the early to mid-afternoon, high temperatures near 94 degrees are expected. With high humidity continuing throughout the day, heat index values of 103 to 105 degrees are anticipated.
Besides the heat and humidity, a few scattered storms are likely to form during the middle of the day. Houston’s overall rain chances will be around 30% to 40%, with the best chances expected between noon and 4 p.m. By the early evening, rain chances will drop to under 20%…
