GUWAHATI, Jan 20 - The upper air cyclonic circulation presently persisting over North Chattisgarh and adjoining Jharkhand and Odisha, which has expanded up to 0.9 km above the mean sea level, together with the wind confluence taking place over the eastern part of India are leading to the present cold weather condition in the NE region of the country.
Under the impact of these two meteorological developments, there is a likelihood of fairly widespread rainfall over Arunachal Pradesh and Assam and Meghalaya Meteorological Subdivisions till 8.30 am tomorrow. During the period, there is also a likelihood of scattered rainfall taking place over the Nagaland-Manipur-Mizoram-Tripura Meteorological Subdivision, said Dr Sanjay O�Neil Shaw, Deputy Director General, Meteorology (DDGM) of the Borjhar-based Regional Meteorological Centre (RMC) here this evening.
However, from the morning of January 21 till the morning of January 22, rainfall activities may become scattered over Arunachal Pradesh and Assam and Meghalaya Meteorological Subdivisions and fairly widespread over the Nagaland-Manipur-Mizoram-Tripura Meteorological Subdivision, the DDGM added.
From the morning of January 22, rainfall activities may become isolated over the region, while from the morning of January 23, there is a likelihood of the weather becoming dry, said the DDGM.
In Guwahati and its adjoining areas, the sky will remain generally cloudy tomorrow and rain or thundershower is most likely to occur in some areas. Tomorrow, the expected maximum temperature in the city is 22� Celsius, while the expected minimum temperature is 13� Celsius.
There is a likelihood of shallow to moderate fog occurring at isolated places over West Assam on the morning of January 21, even though dense to very dense fog is very likely to occur at isolated places over Assam and Meghalaya and Nagaland-Manipur-Mizoram-Tripura Meteorological Subdivisions on January 21 and 22, he said.
Under the impact of the above developments, a chilly weather made life miserable for the Guwahatians today.
According to the RMC Duty Office, the city today recorded a maximum temperature of 17.4� Celsius, which is 6� Celsius below its normal maximum temperature for the period. It also recorded a minimum temperature of 15� Celsius, which is above 5� Celsius of its normal minimum temperature for the period.
