West Rajasthan is heading for rain and thundershower activity between 21st and 23rd March. Jaisalmer, Barmer, Phalodi, Jodhpur and Bikaner are likely to experience a wet spell, the first of its kind in March 2021. The rain belt will extend to cover North and East Rajasthan also during this period. Ganganagar, Hanumangarh, Anupgarh and Suratgarh in the north and Alwar, Ajmer, Sikar, Dholpur and Jaipur on the eastern flank may also receive scattered thunderstorm with intermittent showers.
March and April are the least rainiest month with meagre 4-5 mm of rainfall for both the sub-divisions of West and East Rajasthan. West Rajasthan has practically remained dry this season so far and East Rajasthan has also recorded a deficiency of 27%. This season is in total contrast with the previous year when both East and West Rajasthan received heavy showers during March and observed excess rainfall to the tune of 500%. Mercury has started soaring reaching 38-39°C over the border areas of Jaisalmer, Barmer, Pokhran and Phalodi. Pre Monsoon showed up a little earlier than normal over most parts of the state.
Twist in the weather conditions are likely with rain and thunderstorm activity on 21st and 22nd March and extendable to 23rd March. An active western disturbance is arriving over North India on the night of 20th March. Also, a support cyclonic circulation over North Rajasthan is complementing the main system. Localized heat will provide the additional trigger to enhance the extent and strength of thunder clouds. Few pockets in the northern parts may receive hailstorm accompanied with strong winds in excess of 50 kmph. The entire state can expect relief from extreme heat as the mercury level is expected to drop by 3-4°C and stay below normal during this period.
