The normal day temperature of the city during this period is 23 degree Celsius.
Sources in the Borjhar-based Regional Meteorological Centre (RMC) here said rain at isolated places over Arunachal Pradesh and Assam and Meghalaya Meteorological Subdivisions is very likely during the next 26 hours from 8.30 am today.
However, on January 17 and 18, weather will most likely remain dry over the region with days remaining sunny. But dense fog will mark the morning and evening hours on those days, sources said.
On January 19, rainfall at isolated places over Arunachal Pradesh and Assam and Meghalaya is very likely to occur, while on January 20, rain or thundershower is very likely to occur at a few places over Arunachal Pradesh and rain is very likely to occur at isolated places over the rest of the region, that is, Assam and Meghalaya and Nagaland-Manipur-Mizoram-Tripura Meteorological Subdivisions, sources said.
RMC sources further said the situation is the result of the northerly and northwesterly winds flowing through the NE region and the cloudiness caused by an upper air cyclonic circulation over the Sub-Himalayan West Bengal and neighbourhood. This cyclonic circulation is extending up to 1.5 km above sea level (ASL), said the sources.
