Delhi's temperature has been steadily climbing for the last 5 days. The maximum of 35.1°C on 06th April has soared to 39.1°C yesterday. This is the highest temperature of this year and season, as well. Similar reads were there in other parts of NCR. Mercury level is about 4-5°C above the normal and therefore, just short of heatwave conditions for the capital city. For heat waves, the day temperature has to reach or exceed 40°C and also above normal by 4.5°C or more.
A western disturbance is marked over the northern mountains. A feeble cyclonic circulation is placed over West Rajasthan. An east-west oriented trough from the circulation runs very close to Delhi. Another western disturbance, bigger and active, will arrive tomorrow. This will strengthen the circulation and trough. The Spread and intensity of the weather will increase between 12th and 15th April, for Delhi/NCR.
There are chances of light rain, late tonight and another fleeting spell tomorrow, of similar nature late in the evening. Clouds will keep hovering in between, keeping the sunshine restricted. The main weather activity will be on 13th&14thApril and spill overall effect on 15th April, as well. Rain and thundershowers, accompanied by gusty winds are quite likely. A flash of lightning and peal of thunder may be frequent in the late night hours, during this period. A deep upper air trough and proximity of the westerly jet axis may trigger hailstorms in some areas.
Under the influence of multiple weather systems positioned close to Delhi/NCR, any further rise in the mercury will get arrested. With the likely change in the wind pattern to moist easterlies, humidity levels will increase. On the weekend, peak weather activity will plunge the temperatures to the low 30s. Broad clearance can be expected from 16th April onward. In the wake of the system, strong surface winds are likely between the 16th & 18th April. The break of fair weather conditions may not last long, as another spell may just give a knock, by next weekend.
