Fog and cold days will continue in east Uttar Pradesh and Bihar during the next 24 hours. Fog will be witnessed in west Uttar Pradesh and sub-Himalayan West Bengal during this period. Weather in Delhi including northwest India continues to remain pleasant during the day and cold weather is now restricted to morning and evening hours in these parts. Rain is likely to reduce over east central India while it will continue in southern parts of Tamil Nadu and Kerala during the next 48 hours.
Current weather conditions in east Uttar Pradesh and Bihar will sustain for now. Temperatures are below normal and northwesterly to westerly winds reaching these parts are slowing down. These winds are becoming northeasterly after meeting the easterly winds. This mix up will continue to create fog in these areas.
Fog will also be witnessed in west Uttar Pradesh and sub-Himalayan West Bengal during this period. Dense fog limit could extend to affect the weather in Delhi if northwesterly winds are limited to Delhi allowing easterly to southeasterly winds to penetrate up to the northwest region. But such change in wind pattern takes places when a Western Disturbance restricts northwesterly winds from reaching Delhi.
As a Western Disturbance is expected from 28th January onwards, such fog in Delhi could be expected thereafter. Current Weather conditions in Delhi will continue for now. The weather in Delhi will see bright sunny days during the next two to three days. Rising temperatures have reduced the cold weather only to the morning and evening hours.
Same mix up of winds is being witnessed in east central India, in east Madhya Pradesh and Chhattisgarh. Light rain is expected at one or two places in these areas during the next 24 hours. A cyclonic circulation over Manipur, Mizoram, Nagaland and Tripura will give rain at one or two places in Arunachal Pradesh and adjoining areas. In south, rain is expected to continue in southern parts of Tamil Nadu and Kerala due to their proximity to a cyclonic circulation over Lakshadweep islands.
