It's blazing hot, but the worst is yet to come

The summer heat is finally taking a toll with Delhi recording extremely high day temperature for the fourth consecutive day on Monday. The maximum temperature went up to 43.4 degrees Celsius at Safdarjung, three degrees above normal.
Palam, which received a slight respite from the heat in the evening due to a thunderstorm, recorded a maximum temperature of 45.2 degrees Celsius.
The worst, unfortunately, is yet to come with the Met department predicting a further rise of upto two degrees over the next couple of days.
Dr RK Jenamani, director in-charge at IGI Met, explained how the airport saw a thunderstorm. "Due to very high heating, the air becomes light and rises, leading to convection. Under the impact of this phenomenon, a thunderstorm/dust storm hit the IGI Airport between 7.20 pm and 7.45 pm on Monday evening. During this period, the area saw westerly winds of 55 kmph and the visibility in the dust storm reduced from 6,000 m to just 900 m. The temperature also dropped from 43 degrees Celsius to 37 degrees Celsius. Flight operations were severely affected during this period."
The IMD officials said that such persistent high temperatures were prevailing across Delhi and neighbouring areas and there was not likely to be any respite till at least May 19.
On May 17, heat wave conditions are likely to occur at isolated places over Haryana, Chandigarh, Delhi, Uttar Pradesh and Rajasthan. Dust storm/thunderstorm are likely at isolated places over Punjab, Haryana, Chandigarh, Delhi, west Uttar Pradesh and north Rajasthan, especially in the evening. For Delhi, the Met department has predicted a mainly clear sky becoming partly cloudy from May 19. Rain and thundershowers are likely to occur on May 20.
