Houston saw its hottest weekend of the summer with 100 degree temperatures recorded at the Bush terminal this Sunday afternoon. Saturday's highs also approached 100 degrees very close to the records this August. The week starts with another heat advisory with heat index values again in the low 100s.
The best chance for heat relief will come midweek as the remnants of tropical depression #5 swirl back into the gulf waters. There is a medium chance that the disturbance could regenerate into a depression or tropical cyclone this week. The chances of regeneration improve if the low pressure disturbance moves far enough off shore. Right now most of the reliable models keep the storm near shore, pulling Westerly just North of the Houston area by Thursday, as seen below.
Heat relief may be moving in this week as the rain starts to fall along the gulf coast Wednesday through Thursday. The low pressure system may track further inland closer to Louisiana or Mississippi than Texas giving us far less rain than a Westerly drift over Houston. Right now its too early to tell, but some rain will certainly fall along with the temperatures. High pressure will regain its hold by the weekend.
