We have entered into the last leg of December and winter chill is still evading Delhi-NCR. Thick of winter is yet to make an appearance over the national capital, which we do not foresee in the coming days.
Both the maximum and minimum temperatures have been settling above normal by at least 2-3 degrees for the past few days. So far, night temperatures have not plunged below seven degrees in the season.
On Wednesday, Palam Observatory recorded minimum temperature of 9°C, one degree above normal, while maximum was at 25°C, four degrees above normal. Similarly, Safdarjung Observatory night temperature of 7.5°C, which was near normal and day maximums settled at 25.3°C, four degrees above normal.
According to Skymet Weather, continuous flow of dry northwesterly winds and clear sky conditions lead to bright sunshine, which in turn keeps the mercury on the higher side.
Further, we do expect drop in the mercury after 24 to 48 hours but the drop will be a marginal one and would not make any difference in the prevailing weather scenario.
The ongoing weather conditions can be attributed to the absence of any active Western Disturbances over Western Himalayas. Though back to back Western Disturbances have been approaching Jammu and Kashmir but they were feeble in nature and could not give any significant rain and snow over the hilly region.
Had they given good spell of snow over the hills, winters would have arrived over the northern plains including Delhi NCR.
Since no snowfall has been experienced over the hills, winds blowing from Himalayas are not as cold as they would have been if blowing from the snow-capped region. This has also kept the dense fog at bay from North India, which is also instrumental in dropping the maximum temperatures.
Moreover, these Western Disturbances may not be active to give any weather but they are capable of changing the wind pattern, which in turn leads to increase in night temperatures.
