Pakistan has now entered the month where temperatures decrease rapidly across the country unlike in November. Cool systems became more frequent over northern parts of the country while south-eastern parts mainly remain dry but also could not escape the cool winds.
Major factors affecting Pakistan now
*Fresh western disturbance over northern Pakistan and adjoining area; likely to stay for 2 to 3 days.
*Dry weather to persist in southern parts of Pakistan.
*Fog in the plains of Punjab and Khyber to ease during the current week.
Fog will ease but return!
Fog conditions in the plain areas of Punjab and Khyber are likely to subside from December 20 but will redevelop over the same areas after the western winds move in a NE direction.
Karachi sweats first then shivers!
Karachi after witnessing some unusual warm days of December due to tropical storm ARB 04 that brought moist winds, the city is now under the grip of cold wave. December of 2011 as it leaves us, set the highest temperature in Karachi on December 2 that was 35 °C, highest in Karachi since record keeping began. Following is the list of lowest temperatures during the last few days in Karachi;
- 11 °C recorded on December 19,
- 10 °C recorded on December 18.
- 9 °C recorded on December 17, The lowest of this day was 7 °C in 2005.
- 10 °C recorded on December 16.
- 11 °C recorded on December 15.
The low temperatures have slightly risen since few days but with the approachment of western disturbance 11, the temperature would go done again mainly from December 21. Early morning mist has also developed over the city due to dry air that is likely to stay for few days. There are no chances of rainfall in the current week in the city. However the last week is somewhat unsettled for Karachi.
Cold wave to gain intensity
Northern Pakistan is once again all set to feel the Siberian winds that are once again tracking towards Pakistan. There are greater chances of light rainfall/isolated moderate in Islamabad, Peshawar, Gilgit, Malakand, Hazara, Muzaffarabad and other surrounding areas on December 19 night till December 20 night. Western disturbance 11 has caused isolated heavy rainfall in north-eastern Afghanistan but its intensity has weakened by the time it entered Pakistan, however showers will be accompanied by fast winds. However the most rain-bearing part will be over the northern borders of Pakistan and they will gradually move eastwards as WD 11 moves out of the country, but the cool winds will keep penetrating into the country. The cool winds have also entered Gujarat, Rajasthan, East Punjab and Haryana states of India. The Siberian winds have also engulfed Sindh and south Punjab.
In Karachi, the night temperatures would range from 10 °C – 7 °C till December 25 and then it will start to rise slowly.

Hi,Babar, Is there a possibility of some good cold weather in karachi. I am saying about dec end and jan and any possibilities of getting some rains.
Cold wave that had engulfed the city since last few days has ended, now the night temperatures would rise to some extent (10°C – 12°C) but then again they would drop from the weekend as cold winds penetrate through western Pakistan. Last days of the first week of January is unsettled but not much promising.
