All India forecast for next week from 1 May 2022 till 7 May 2022:
o The pattern of heatwave will continue in most parts of North West India and Central India on Sunday, probably West Rajasthan will have the hottest day of the season as temperatures might reach close to 47-48?C in Jaisalmer, Bikaner, Churu and Sriganganagar.
o Early next week a Western Disturbance is expected to approach Western Himalayas and it is expected to have some impact over the plains as well.
From 2 to 5 May, convective clouds will develop daily in the late afternoon to evening hours over Punjab, Haryana, Rajasthan, Delhi and Uttar Pradesh causing dust storms and scattered light to moderate rains in the region which will bring down the temperatures by 4-5?C and residents might get respite from ongoing heatwave but still day time temperatures are expected to be around 40?C hence days to stay slightly hot.
o Under the influence of Western Disturbance various parts of Jammu and Kashmir, Ladakh, Himachal Pradesh and Uttarakhand to receive on and off light to moderate rainfall activities throughout the next week.
o As the Western Disturbance approaches northern India, wind reversal will take in east India. Under the influence of Easterlies, the moisture content will increase in the Gangetic Plains and along with the combined impact of Western Disturbance, strong norwesters are expected to develop in East India during the upcoming week.
Intense thunderstorms, heavy rains and winds gusts above 50km/h and up to 100km/h likely in Bihar, Jharkhand, West Bengal, Odisha and parts of Chhattisgarh daily in the evening hours during the whole week.
o The weather conditions are expected to stay dry in most parts of Gujarat, Maharashtra, and Madhya Pradesh this week as no significant weather system is likely to impact the region. The maximum temperatures will remain slightly above normal by 2-3?c and in the range of 40 to 45?C during the upcoming week.
o Things get more interesting in South India as weather models hint at a strong agreement for the formation of a low-pressure area in the Bay of Bengal towards the end of the next week and the system might intensify gradually into a cyclonic storm by the second week of May. The East coast of India, Bangladesh and Myanmar will remain potential landfall locations. The genesis of the tropical system holds the key to forecasting the intensity as well as the landfall location.
It will be tricky to guess it right now as it is too early. There will be a noticeable increase in pre-monsoon rains in Kerala, Karnataka, Goa and Western Tamil Nadu this week and the temperature is expected to stay below normal in the southern peninsula over the week.
