As we all know, the month of April this year was the second coolest in a decade. The reason for this cooler than average temperatures over north West India can be attributed to successive Western disturbances which induce cyclonic circulation over northern Plains of Punjab, Haryana, and sometimes over Rajasthan. that is why most of the states of Northwest India, as well as Hills, are large rain excess.
On and off rain activities did not allow temperatures to increase. The month of April did not witness any heatwave over North West India during April. Usually, one or two heat waves are common.
Almost all the Eastern states remained large rain excess during the month of April. The rain activities increased over East and Northeast India during the third week of April and are continuing until now. The rains over east and North East are due to continuous moisture feed from Bay of Bengal and persistence of cyclonic circulation over northeast India.
Although now we expect temperatures to increase to some extent over Northwest India during the next 2 to 3 days. Another Western disturbance is expected around April 30, there may be scattered rains over North West India. Between May 1st and 3rd, due to dry weather, the temperature may increase once again. Weather activities will once again enhance over Punjab, Haryana, Delhi, West Uttar Pradesh and North Rajasthan between May 3rd and 6th. These activities will once again bring down the temperatures.
Similarly, east India will continue with moderate rain and thundershower activities until May 1st. Rains will once again increase over west Bengal, north Odisha, Jharkhand, many parts of Bihar and East Uttar Pradesh between May 4 and 7,
Weather will not clear up over the northwest and Eastern parts of the country until the first week of May. Therefore, temperatures will remain below normal or near normal. The typical heat of May will not arrive until the 2nd week.
