Mercury went up by one to six degrees Celsius in most places due to change in wind pattern in the state with Sriganganagar recording the lowest temperature at 5.6 degrees Celsius last night, a Rajasthan MeT official said.
Temperature rose sharply at hill station Mount Abu from 4 degrees Celsius to 8.0 degrees Celsius last night.
However fog appeared in parts of north-eastern Rajasthan covering Alwar, Sriganganagar, and Hanumangarh, while dense fog in neighbouring states of Haryana, Punjab and Uttar Pradesh led to delay of 11 trains and rescheduling of two.
Ajmer-Jammu Tawi and Jaipur-Allahabad trains have been rescheduled to avoid fog, he said.
The rise in minimum temperature ranged between 1 degree Celsius and 6 degrees Celsisus in Ajmer, Jaipur, Pilani, Kota, Sawimadhopur, Udaipur, Barmer, Jodhpur, Bikaner, Churu, and Jaisalmer.
Mercury would further increase as a new western disturbance and wind pattern is likely to hit the state in the next 48 hours, the weatherman said.
