Temperatures far surpassed the 100-degree mark across much of India and Pakistan earlier this week, but slightly cooler weather could be on the way by this weekend.

According to AccuWeather.com meteorologists, a trough will weaken the ridge responsible for the recent hot weather across the region, allowing at least some cooling to occur Friday through the weekend.

Slightly lower high temperatures, around 115-118 F (upper 40s C), are expected Friday through Sunday.

However, meteorologists foresee the ridge rebuilding, bringing back highs in the 120s F (50s C) by the middle of next week.

Jacobabad, Pakistan recorded a high temperature of 124 F (51 C) Thursday.

Temperatures reached as high as 127 F (nearly 53 C) in parts of Pakistan Wednesday.

Delhi, India reached 113 F (45.2 C) Wednesday, which is the hottest temperature recorded there in four years.

Schools were shut down in Haryana, India. Several deaths in the last two weeks have been blamed on the heat.
