Heatwave to continue despite Duststorms and Rains in India

 

Anti-Cyclonic circulation which dominated central and northern India has finally weakened and faded away making a way for WDs to comeback and affect Indo gangetic plains and adjoining areas.

Last week as forecasted parts of north India including Delhi, Punjab, Haryana, Rajasthan and parts of western UttarPradesh recorded first spell of Duststorm and rainfall of this summer season but in both spells Delhi somehow managed to get only dust raising winds with light drizzle and escaped the core Duststorm.

Heatwave was abated from many of the above mentioned places as temperature fall due to clouding and patchy rainfall at some places but heatwave prevailed in many parts of central India and Uttarpradesh.

Weather forecast for next 5 days

Weather Synopsis 

• 3 westerners disturbances in quick successions are expected to affect parts of Himalayas and plains of North India but their spread will be less as they all are weak ones.

• Flow of Hot and mostly dry westerlies

Effects and sequence of these systems and activities 

First WD will impact the hills on 17th April then followed by 2nd WD from 19th April and 3rd WD fron 21st April. They will be not much effective as their intensity and spread is expected to be less also temperatures will rise despite these activities  as flow of hot westerlies will continue and is not hindered too much by any of these systems. There will be on/off isolated Duststorm and dust raising wind activities on 17, 18, 19 and 20-22nd April across the parts of Punjab, Aravalli, W-N Rajasthan and few nearby places

Influence of these weather systems over plains and hills

Plains

Wx will remain mostly dry with some partly cloudy sky during late afternoon into late evening hours across Delhi, Haryana, E,N Rajasthan and Aravali and parts of western Uttarpradesh on 18th April

In general afternoons will be hot but instability will fuel with clouds and it’ll bring short relief from heat due to isol rains
