Rain is Delhi expected to begin tomorrow as the Western Disturbance will move from north Pakistan to Jammu & Kashmir during the next 24 hours. The movement will also bring more snowfall in Jammu & Kashmir and in Himachal Pradesh and Uttarakhand later on. Heavy snowfall equivalent to 400 to 700mm or rain, is expected to occur in Jammu & Kashmir on 15th of February. The snowfall period will last for three to four days.
After making a start tomorrow, rain in Delhi will intensify to lash many places in the city on 15th and 16th of February. One or two places are expected to receive hailstorms as well. The cyclonic circulation associated with the Western Disturbance lies south of Delhi anywhere in south Rajasthan and while moving northeastwards, it will merge with the Western Disturbance near Delhi by 16th, so there is possibility of heavy rain in Delhi as well.
Wind conditions will supplement the rainy weather in Delhi as it will receive moisture feed from the Arabian Sea and the Bay of Bengal, riding on southwesterly and southeasterly winds. Rain in Delhi and snowfall in Jammu & Kashmir will bring the night temperatures down after the exit of the Western Disturbance. But during its stay, minimum temperatures would rise by 2 to 4 degrees as northerly winds will be cut off.
