The drop in minimum temperatures with moderate winds will continue the cold wave in Delhi and surrounding areas during the next couple of days. Fog in Delhi is unlikely during this period. Rain in Assam and Arunachal Pradesh is expected during the next two days. Vidarbha, east Madhya Pradesh, Chhattisgarh and Orissa will also receive rain in the next 72 hours.
The icy and speedy northerly to northwesterly winds will continue to blow in the next two days and will bring the night temperatures down by another 2°C. So, the cold wave in Delhi and nearby areas will further penetrate and aggravate over Rajasthan, Madhya Pradesh and west Uttar Pradesh with below normal minimum temperatures.
Winds are speedy so there is no change of fog in Delhi. The winds are blowing at 15 to 20kmph and pushing the moisture out of the region. Some moisture is still left in the foothills of Himalayas near Nepal border with Uttar Pradesh as winds here are slowing down a bit. In a day or two, winds will again strengthen to flush out the moisture. Heat radiation due to open sky in Delhi will continue to keep the maximum temperatures below normal. Days in Delhi will also be cooler during the next two days.
East central India is expected to witness a front between cool and dry northwesterly winds and warm and moist easterly winds from the Bay of Bengal so rain can be expected in these parts during the next 72 hours. These places will have a partly cloudy sky becoming cloudy at times.
Rain in Assam along with Arunachal Pradesh is expected in the next 48 hours as a cyclonic circulation lies over Assam. A few places could receive rain during the next 24 hours. Rain will reduce thereafter and would occur at one or two places. The weather will turn dry and cool after the cyclonic circulation becomes less effective thereafter.
