GUWAHATI, Dec 26 � The variation in day and night temperatures may be held responsible for the present cold weather situation in a part of the NE region, said sources in the Regional Meteorology Centre (RMC) here today.
According to the sources, a foggy condition from the Northwestern part of the country is spread to some parts of western Assam, covering Delhi, Uttar Pradesh, Bihar, West Bengal and Bangladesh.
In the rest of the NE region, the sky is relatively clear.
Due to the passage of a western disturbance along the northern latitude of our region about two days back the day temperature has dipped. For example, sources said, on December 24, Guwahati recorded a maximum temperature of 26.2 degree Celsius. It recorded a maximum temperature of 23.5 degree Celsius yesterday and 23.4 degree Celsius today.
The day temperature of the city was below 1 degree Celsius of its normal day temperature, where as its minimum temperature is up by 1 degree Celsius, sources said.
The city recorded a minimum temperature of 8.5 degree Celsius on December 24, 9.4 degree Celsius yesterday and 11.9 degree Celsius today.
However, there is no significant rain-causing weather system prevailing over the NE region. Mainly easterly/ northeasterly wind prevails over the region in the lower level of the atmosphere.
Weather will remain mainly dry over the region during the next 48 hours. But in Guwahati and its neighbourhood the sky will be hazy and fog or mist is expected in the morning during the period. The minimum temperature of the city will remain around 11 degree Celsius tomorrow, said the sources.
