Synopsis of Monday 30th:
Rains were reported on Monday 30th, in the vertical strip in North India stretching Southwards roughly from Dehra Dun into Central MP.
An upper air WD ( 700 hpa-500hpa) has moved over Punjab region. The SE and Eastern quadrant of the system id deeper, with resultant SW winds at upper level blowing at 40 knts in the mentioned segment. SW winds at 10000-18000 feet were perfect for cloud condensation, with the already low temperatures. Rising to 18000 feet resulted in thunder cloud formations.

Cold Wave abating  a bit in the start of 2014...
Tuesday 31st, rainfall will occur in Punjab, Haryana, Delhi NCR and adjoining West UP. Also, some Northern regions of MP will get showers. Cloudiness will prevail over the Northern bordering Mah. areas.

Delhi NCR will be partly cloudy and hazy on Tuesday, with showers in some areas. Day will be around 18/19c and Tuesday night will be around 10c. Skies start clearing from New Years Day, and Thursday 2nd and Friday 3rd morning will be foggy and cooler at 5/6c.

Mumbai will be partly cloudy, and around 28/29c on the last day of 2013. 31st night  maybe less cooler than the few preceding nights, at 19c in the suburbs and 21c at Colaba.
New Years Day will be hazy, and warm at 30c, but getting warmer at 31c on the 2nd day of January. Nights are expected to hover around 18/19c at Scruz and 20c in South Mumbai till the end of the week.
Outer townships too, will be partly cloudy and "warmish" compared to the previous week on 31st night.
Pune will be sunny, and 31st Night will be pleasant at 13c.. first week of 2014 will be  between 30c and 13/14c.

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.

Coldest morning of this winter in Kathmandu yesterday, as reported, at 0.5 C. Suburbs and outskirts are even colder - a place i visited yesterday in the southeast of the city reporting thick frost in the morning - not melting till 10 AM or so. Don't know the exact min temp there but should be a few notches below freezing.
Day's high at around 17 C is keeping things warm for the day though.
