Delhi has witnessed absolute dry weather conditions in October, so far. After the withdrawal of the southwest monsoon, the city has observed typical transition conditions. Day and night temperatures have both shown slippages, but they are getting back to the warmer phase, yet again. The day temperature has hovered around 36°C for the last four days and the minimum also breached 20°C during this period. A slight twist in the weather conditions is likely during this week.
A feeble western disturbance will move across the mountains, largely affecting the higher reaches only. Classic wintry wind pattern is likely to catch up over the plains of North India. Northwesterly winds, both, with speed and strength will blow across the slopes of hills and sweep the northern plains, shortly. Delhi, too, will observe this change and lead to arrest in any further rise of temperatures.
The base observatory at Safdarjung recorded a maximum of 35.8°C and a minimum of 20.4°C, both above normal by 2°-3°C. The highest temperature in the Delhi area was 36.5°C, recorded at Pitampura. A similar trend is expected today as well. Surface winds will remain light and variable allowing warming in the lower levels. Change in the winds is likely from tomorrow and more authentically from a day later. Though, no clouds are likely to restrict the warming but northwesterly winds with a fair amount of force will bring some cool in the lower levels. Day and night temperatures will have a drop. A slight nip in the air with a minimum of around 18°C and a maximum lowering to about 34°C is expected. These conditions will last between the 23rd and 26th of October. Another western disturbance will approach the mountains from 27-28 October onward. This may induce the change in the plains, yet again.
