Cold is holding its grip over the Northern region of the sub-continent.

The lowest in the Indian region was Adampur (Punjab) which saw a low of -0.4c on Monday, with Hissar in Haryana at 0c on Monday. Amritsar with 1c was another place with extremely low night temperature.

The days were cold in U.P. and adjoining regions on Monday. Varanasi at 14c in the day being 11c below normal, Allahabad having a high of 15c, which was 10c below normal. All places in the region were around 7-10c below normal in the day.

The persisting cold wave is attributed to the high pressure area (upper air) sitting over the area. With the NW winds starting after the W.D. passes, say by the 21st, we can expect the days in the North to become normal, and cold winds would sweep the NW and central regions.

Meanwhile the W.D, mentioned in Sunday's blog, is moving into the Kashmir region. Would expect Srinagar to receive its first snow on Tuesday.

Snowfall, heavy on the higher portions, is expected on the Jammu-Srinagar highway on Tuesday. Travelers are expected to be prepared for closures in parts.

Delhi will be partly cloudy next 2 days, with the night temperature going up marginally to 7c; with the days will be around 20c.

Mumbai: Tuesday and Wednesday: Partly cloudy with high cirrus clouds. Max in the day will be around 32c, and night temperature should be 18/19c.

Pune: Tuesday and Wednesday: Partly cloudy with thick cirrus clouds (high). Day will be around 31c and night will be 12c.

Surat will be clear, with the day /Night range between 31c and 19c. Expecting cooling after the 24th.

An Easterly wave (mentioned in Sunday's Blog) will bring some rains to the South T.N coast on Tuesday and Wednesday. As mentioned earlier, a pulse from the typhoon Washi hold on to a chance of a system coming towards the East coast around the 25th.
