Delhi is expected to have minimal weather activity in the remaining days of the month. Yesterday, it remained completely dry over the entire NCR. Practically, it rained somewhere or the other in the Delhi area between the 03rd and 20th of August. Earlier, similar weather conditions were observed on 02nd Aug. Yesterday, the absence of rain, partial clouds and light breeze led to a rise in the day temperature. For the first time in this month, the mercury crossed 36°C when the maximum temperature touched 36.2°C, about 2°C above the normal. Similar conditions are expected today, as well as a change, thereafter.
The monsoon trough was the main trigger for prolonged monsoon activity over the national capital for nearly three weeks. The trough has shifted north of Delhi in the lower levels and therefore, the surface wind has changed to a westerly direction. Westerly winds being less humid, lead to a rise in temperature. The monsoon trough is expected to oscillate first and then shift south of Delhi, after 48 hours. Though this will bring some twist in the weather conditions, no hefty rains are likely over the next few days.
There is a low-pressure area marked over North Bangladesh and West Bengal. The system will slowly shift westward and the cyclonic circulation will reach central Madhya Pradesh on 24th August. This will initiate the change in the position of the seasonal trough above the friction level. The next day, this well-marked circulation or possibly a low pressure will move over Southwest Madhya Pradesh and Southeast Rajasthan. Peripherals of this feature will encroach parts of Gujarat and North Madhya Maharashtra, as well. Next two days, the system will largely affect the state of Gujarat.
Movement of this low pressure will drag the monsoon trough well south of its normal position. Since the weather system will keep a safe distance from Delhi, the national capital will generally remain unaffected. Yes, when the trough, during its southward shift passes over Delhi, it may give scattered showers, for a short duration. Such an activity is more likely on 24th & 25th Aug. Once again, no hefty rains are likely. The trough is unlikely to resume its normal position before 31st August 2024. Accordingly, monsoon showers will remain sparse and fleeting over the national capital and suburbs, right till the month's end.
