Karachi is expected to get cloudy weather on Monday 7th, with moderate West/SW winds. Tuesday gets more windy, with wind speeds increasing to 35 knts. Light Showers in some parts also expected on Tuesday 8th. An overcast day on Tuesday leads to a windy and cloudy Wednesday, as strong West/SW winds continue to blow in Karachi. A few spells of light rain possible in some parts on Wednesday (around 3-5 mms). Humidity increasing from gradually during the week.

Mumbai: Partly cloudy skies on Monday and Tuesday, with the day around 33c, with mild nights. Wednesday warms up to 35c in S'Cruz. If things shape up as i expect, we can have a chance of some showers on Saturday 12th (No firm commitment at this stage).
M-2 approaches Pakistan from the West and the trough brings in initial precipitation along Southern Pakistan from 8th March. Slowly, due to poor divergence in the jet streams, the system moves into Kashmir and Northern India a bit later, around 10th March.
Hence, precipitation from M-2 can start in India after Thursday 10th. We see proper precipitation in North and Central India then onwards.
