An active Western disturbance is moving across Western Himalayas and an induced cyclonic circulation is over Central Pakistan and adjoining parts of Punjab. These weather systems are responsible for rain and thunderstorm. Both the states have witnessed frequent showers during second half of March and first week of April. That is why between March 1 and April 19, Punjab is rain excess by 124% and Haryana by 141%.

Places like Karnal, Amritsar, Ludhiana, Patiala, Kurukshetra, Rohtak and Jalandhar have been recording maximum temperatures in mid-thirties. Whereas maximums of these districts were 40 degree or more until April 19.
The Western disturbance will move away gradually and the intensity and spread of rain will also decrease over these States. However, there are chances of light to moderate rain over northern districts of Punjab for another 24 to 48 hours. Northern parts of Haryana may receive scattered rain for another 24 hours.
