The maximum temperature is expected to hover around 41-42°C 0n 09th and 10th June.
Rain and thunderstorms are likely over the weekend which is likely to spill over even to the next week. Weather conditions will change with the double front attack reversing the wind pattern and therefore the relief. Maiden monsoon depression of this season in the Bay of Bengal is expected to cross the Odisha-West Bengal coast on 12th June. This will usher monsoon flavored easterly winds all along the Indo Gangetic plains reaching up to Delhi. Also, a western disturbance with induced cyclonic circulation will approach Punjab and Haryana around this time. Under the combined influence of these two weather systems, Delhi and the neighborhood is expected to have rain and thundershower between 12th and 14th June. This may be accompanied with lightning and squally winds to the tune of 60-70kmh. The wet spell may get extended further with a short break in between on 15th June.
