Delhi and the NCR region has once again started to shiver with temperatures dropping below 5° for the last couple of days. Moreover, the national capital's base observatory recorded the minimum at 1.4°C today making it the lowest of the season. Not only this, but this minimum is also the second lowest for the month of January in the last decade with the lowest observed at 1.1 degrees Celsius on Jan 1, 2021.
The current minimum is 6° below the normal levels resulting in severe cold wave conditions across Delhi and the NCR region.
The reason for this drop in temperatures is attributed to the passage of the western disturbance. The last western disturbance resulted in a lot of snowfall over the hills of north India. After the passage of the system, there has been a continuous flow of icy cold north westerly winds over the North Indian plains resulting in a drop in temperatures.
These weather conditions are expected to continue for a couple of days. There is expected to be relief in terms of temperature around January 18, when a fresh disturbance will approach the western Himalayas and will result in the increase of minimum temperatures.
