As per India Meteorological Department (IMD), temperature is likely to cross 40degC again from Saturday. This follows as trace rain (less than 0.1 mm) was recorded at the IMD observatory on Friday morning. As per IMD, a western disturbance is active over the region which led to dust storms and light rain in parts of Himachal Pradesh. Because of the impact of the WD, maximum temperature fell from 44.2degC on Thursday to 39.3degC on Friday, at normal.
