Capital city Delhi is likely to receive a long spell of pre monsoon showers. Weather activity is likely to commence around 16th March night, persist over the weekend and spill over to the next week, as well. Rains are not going to be heavy and at best may include one or two moderate showers during the entire period. However, cloudy sky will make appearance tomorrow onwards and persist for the complete duration with short breaks in between.
