A trough runs from north interior Karnataka to north interior Odisha in lower tropospheric levels and there is a cyclonic circulation over south Konkan in lower tropospheric levels, under the influence of which, the IMD said, there would be scattered to fairly widespread light/moderate rainfall very likely over coastal Andhra Pradesh till January 16 and isolated to scattered light/moderate rainfall over Marathwada, Vidarbha, Chhattisgarh, and Telangana on Saturday.
On Saturday, isolated light/moderate rainfall is very likely over sub-Himalayan West Bengal, Sikkim, and Jharkhand, isolated thunderstorms with lightning/hail very likely over sub-Himalayan West Bengal and Sikkim, and isolated light/moderate rainfall over Arunachal Pradesh, Assam, Meghalaya, Nagaland, Manipur, Mizoram, and Tripura.
Under the influence of a cyclonic circulation over southwest Bay of Bengal and another over south Tamil Nadu in lower tropospheric levels; isolated light rainfall/thundershower is expected over Tamil Nadu, Puducherry, Karaikal, Kerala, and Mahe during the next 4-5 days.
Two fresh Western Disturbances are very likely to affect northwest India, the first from January 16, which is likely to cause isolated to scattered precipitation on January 16 and 17; while the second would be from January 18 and is likely to cause light/moderate scattered to fairly widespread precipitation over Western Himalayan Region and light isolated to scattered rainfall over adjoining plains for subsequent 2-3 days.
The IMD said there would be no significant change in minimum temperatures in northwest India during the next three days and rise by 2-3 degrees Celsius thereafter. It also said, there would be no significant change in minimum temperatures over east India during the next three days and fall by 2-3 degrees Celsius thereafter.
