The same trough may also hit East India, bringing light isolated showers, thunderstorms, and lightning to Bihar, Jharkhand, West Bengal, and Odisha from April 22 to 24.

During this time, Madhya Pradesh, Vidarbha, and Chhattisgarh may see mild to moderate isolated rainfall, thunderstorms, lightning, and gusty winds. On April 23, isolated hailstorms are possible in Chhattisgarh.
Temperatures will fall below average due to a cooler air loft above West Bengal, which will spread to the East and Central regions beginning Friday.
