Fog and clouds, formed due to the impact of a western disturbance passing through the northern parts of the country, have pushed up night readings across Jharkhand.

The dense fog resulted in poor visibility just after sunrise at several places on Monday. Surface visibility was reduced to below 700 metre at areas across the Kolhan region, including Jamshedpur.

Ranchi, Daltonganj, Dumka, Giridih, Bokaro, Sahebganj and Latehar also experienced poor visibility.

"Several districts witnessed partly cloudy sky with moderate to heavy fog on Monday morning. The wind pattern over Jharkhand has changed from north-westerly to easterly due to the impact of the western disturbance. This in turn has resulted in a rise in minimum reading across Jharkhand," said a duty officer at IMD's Ranchi Meteorological Centre.

The Ranchi Met centre in its forecast for the next five days also predicted rain and thundershowers in north-western, central and southern Jharkhand on January 28 and 29.

On Monday, Ranchi and its adjoining districts recorded a minimum temperature of around 12 degree Celsius while the minimum reading of Jamshedpur shot up to 15 degrees.

Daltonganj and Bokaro districts recorded a minimum of around 11 degree Celsius while Dumka, Chaibasa in West Singhbhum, Pakur and several other places recorded minimum temperatures of around 12 degree Celsius.
