The states of Punjab, Haryana, and North Rajasthan saw some good rains around May 3 and 4. However, thereafter, dry weather has been persisting over the region with temperatures settling above normal or around the normal.
Moreover, there have been several stations that saw yesterday’s maximums touching the highest point for the first time this season. For instance, Ambala settled at 41.4°C (four degrees above normal,), Chandigarh 40.4°C, Amritsar 40.2°C, Patiala 42°C, Sri Ganganagar 45.6°C, and Churu 45.5°C.
A similar situation is likely to continue on May 8 and 9. May 10 onward, the weather activity will build up for quite a number of days.

For the first three days, i.e. between May 10 and 12, weather activity will be mostly limited to thunderstorms, lightning, and dust storm over Punjab, Haryana and North Rajasthan. Delhi and the NCR region will also see rains during this time. Meanwhile, between May 13 and 16, widespread rains and thundershowers are expected over these areas as both intensity and spread of weather activities will increase. Even May 17 may see some showers.
These rains will be attributed to the upcoming successive Western Disturbances and their induced Circulations which will first begin rains in the hills of North India.
During this time, temperatures will drop, and summer heat and heat wave like conditions, which are prevailing in pockets will take a backseat. Temperatures are likely to drop around below normal around 35 degrees Celsius or so. Moreover, the foothills may see these temperatures dropping even below 35 degrees.
This upcoming rainfall episode will be the longest Pre Monsoon spell for the region and will be spread to many areas.
Northwest India enjoys Pre Monsoon season a little longer than the rest of the regions. Moreover, Pre Monsoon extends over the plains of North India beyond the months of May as Southwest Monsoon does not arrive until fag end of June and in some places, even during the first week of July.
However, temperatures during the month of June are way better as compared to the months of May, which is undoubtedly the hottest. June happens to be a shade better since other adjoining areas see the arrival of Monsoon due to which wind direction changes resulting in a marginal drop of temperatures.
