What's in store of a Long Range Forecast for 1st Half of January 2014 ?
An Easterly wave has formed east-west along the 8N line. An embedded UAC will form in the trough, and move WNW. It will gradually become well marked (BB-1), and move into Southern most TN and Kerala by around 4th January. Chennai will be cloudy, with some showers by Friday.
Another system (BB-2) may march westwards and cross the TN coast around 13th January.
Another western disturbance, J-1, moves into Kashmir and HP around the 7th. Since the Upper air trough will slant eastwards, this system will bring negligible rains west of Delhi (including Pakistan). This system will precipitate rains most probably along UP and the Eastern states of Bihar and then Bengal (including Kolkata) around the 8th/9th.
J-1 is expected to bring good rains to Nepal.
J-2 will be more effective and strong, and will bring good precipitations to entire Pakistan (upto Karachi) and move into India. This will be around 13th January by rough and approximate calculations.
