Today on 26.4.2012 the minimum temperature rose to 21.2 oC against the normal of 19.2 oC which lowered down the atmospheric pressure level and causes the disturbance.

According to IMD forecast, cloud imagery showed convective clouds over parts of Jammu & Kashmir and low/medium clouds were seen over Punjab. The western disturbance over Jammu & Kashmir and neighbourhood moved eastwards, which has caused thundershowers over the region. A fresh western disturbance as an upper air system lies over north Pakistan & neighbourhood and an upper air cyclonic circulation lies over southeast Rajasthan and neighbourhood in lower levels. It would affect the North-west region including Punjab during next 2-3 days and duststorms/thunderstorms would occur at one or two places over Punjab, Haryana, Delhi, Rajasthan and west Uttar Pradesh. . The wheat crop is at harvest maturity but now it needs sunny days to harvest. As the moisture has increased, the farmers are advised to delay harvesting until the weather opens up.
