The reason for such high temperatures is a cyclonic circulation forming over Bangladesh and a trough extending form North Bengal to Bangladesh and another trough across Arunachal Pradesh.
This sort of system normally affects Arunachal Pradesh and Assam in the form of light rain and thunderstorm or thunder squall.
Normally this type of weather activity occurs during afternoon or evening hours. So going back to home from work in the evening could result in wet clothes, better to keep an umbrella handy.
In the coming few days, the cyclonic circulation is expected to be more marked and the activity will increase more in the Northeastern States. The squally winds are expected to touch the speed of 80-100 kmph in few areas.
This part of the country generally contributes the highest amount of rain during the winter months, along with North India. However, this year has seen exceptionally less rains in most parts of North and Northeast India.
