Entire North India and the national capital is reeling under soaring conditions. Mercury has breached the 40-degree mark at most places and is scaling 4-5 degrees above the normal amounting to heatwave conditions. Chandigarh recorded 42.3 degrees (+5), Bhatinda 42.5 degrees (+4), Patiala 41.7 degrees (+4), Hisar 43.4 degrees (+3), Sirsa 44.5 degrees (+4), Churu 44.6 degrees (+4), Tonk 44.2degrees (+4), and Aligarh 43 degrees (+4). Delhi exceeded 42 degrees for the 2nd consecutive day to register 42.1 degrees, a shade less than 42.2 degrees of the previous day. Delhi may record a hat trick today.
Typical of pre-monsoon season, excess heat is generating a small scale cyclonic circulations and also a couple of western disturbances transiting through the region. Northern parts have already experienced light rain and thunderstorm along with squally weather over Rajasthan in the past 24hr. This activity will pick up further and lash many parts of Punjab, Haryana, Rajasthan, Delhi, and West Uttar Pradesh lasting for nearly one week with short breaks in between.
Pre-monsoon activity will continue and increase its span in the next 24 hours. This may go a little subdued in the subsequent 24 hours, on 03rd and 04th May. Substantial rise is expected between 05th and 08th May covering most parts of Punjab, Haryana, North Rajasthan, and Delhi. Dust storms accompanied with strong winds gusting 70-80kmh is quite likely over these parts. This activity will be followed by rain and thundershowers dropping the temperatures by 6-8 degrees. Heatwave conditions will therefore abate from the region in the next 48 hours and thereafter remain good for the subsequent 4-5 days.
