Delhiites woke up to a pleasant breezy morning as rain hit some parts of the city on Friday.
Met officials predicted thunderstorm with rain throughout the day and a dip in day temperature from around 44 degrees Celsius to 40 degrees, and further to 36 degrees by the weekend, as more such thunderstorms are likely over the next few days.
“While a western disturbance triggered the rain and thunderstorm earlier this week, a cyclonic circulation over Delhi-NCR is the reason behind today’s thunderstorms,” said a senior official of the Regional Weather Forecast Department.
“Saturday will also be cloudy with possibility of dust storm, and rain with thunderstorm is expected again on Sunday. The minimum temperature would be around 27 degrees Celsius,” the official said.
While the thunderstorm helped cool the air at high altitudes, convection currents allowed the colder air mass to come down to lower levels, helping bring down the temperature.
Usually May and June are the hottest months in Delhi, with day temperatures often shooting above 45 degrees Celsius .
“But such interim reliefs triggered by western disturbances and cyclonic circulations in the summer months help keep the rising mercury level under check. Without such checks, the mercury would shoot up, resulting in heat waves,” the official said.
This year since April, the maximum temperature has hovered above the 40 degrees Celsius mark.
