The IMD, in a statement, said that considering the prevailing meteorological conditions, cold day to severe cold day conditions in many pockets are very likely to continue till December 29 over Punjab, Haryana, Chandigarh and Delhi and Uttar Pradesh and in some pockets over north Rajasthan, cold day conditions at isolated pockets also very likely over Madhya Pradesh and Bihar but abating thereafter.
Reportedly, most stations in the capital have recorded severe cold conditions continuously for 12 days. Delhi had also experienced cold wave spell in four years -1997, 1998, 2003, and 2014.
The severe cold conditions are prevailing due to persistence of cold northwesterly winds in lower levels over northwest India and other favourable meteorological conditions. Since December 15, many states in northern India are reeling under severe cold wave conditions.
According to the IMD, the most severity was observed on December 25, when majority of stations in the region recorded 7-12 degrees Celsius below average with actual maximum temperature of the day varying between 9-15 degrees Celsius. "The lowest day maximum temperature on this date in the plains was reported at Ganganagar and Chandigarh with 9 degrees Celsius," said the IMD statement.
The capital recorded a severe cold day on Wednesday with the maximum temperature dropping to 12.7 degrees Celsius, which is nine degrees below the average, while the minimum temperature was 6 degrees Celsius, two degrees below the average.
The minimum temperature on Wednesday night was recorded at 6 degrees Celsius and the weather bureau said it was 7 degrees Celsius at 5.30 a.m. on Thursday.
The IMD also predicts light/moderate isolated to scattered rain/thundershowers over Punjab, Haryana, Chandigarh and Delhi, north Rajasthan and Uttar Pradesh between December 31, 2019 to January 2, 2020.
"Isolated thunderstorm/hailstorm at isolated places is also likely to occur over south Uttar Pradesh on January 1 & 2 2020," it added.
