Lucknow  Weather

During the first week of January, many parts of Northwest India witnessed dense to very dense fog. Thereafter, moderate winds from the northwest direction continued to blow over the region which did not allow the fog to settle down.

However, since the last three to four days, a Western Disturbance has induced a cyclonic circulation over Northwest Plains leading to change in wind direction from northwesterly to southeasterly and southwesterly.

Due to these winds, humidity levels increased. Moreover, wind speed also decreased significantly, and temperatures were already running low. Therefore, all these factors led to formation of dense to very dense fog.

In fact, during the morning hours of today also, the visibility at Amritsar dropped to a mere 50 metres. Meanwhile, Palam observatory saw its visibility drop to nil while Safdarjung saw the visibility at 200 metres.

Now, the Western Disturbance is moving away, and cyclonic circulation has also shifted to Southwest Rajasthan which will gradually fade away. Now, dry and cold northwesterly winds will once again start blowing over Northwest India and speed of winds will also increase leading to abatement of fog.

However, isolated pockets may continue with shallow to moderate fog but by and large Northwest India will become fog free.
