India: Chennai to Dry Out Next Week After Historic Rainfall

A change in the weather pattern across India later next week will bring a much-needed dry spell to flood-weary Chennai and the potential for rain across central and northern India.

A shifting area of high pressure will finally allow drier air to push into southern India later next week, ending the dry days with poor air quality in northern and central India.

The high will suppress the tropical moisture out of Chennai, putting a lid on shower and thunderstorm activity, giving flood waters a chance to recede and the ground to dry out.

"After that, the heavy rain threat should be over for this winter around Chennai," AccuWeather Senior Meteorologist Jason Nicholls said.

However, not all of southern India will dry out. The moisture from the Bay of Bengal will still stream over far-southern India, allowing the stormy weather to persist.

The shifting high will also open the door for moisture from the Arabian Sea to get pulled northward ahead from a pair of storm systems arriving from the Middle East.

That should allow rain, at least in the form of showers, to spread into Gujarat, Maharashtra and Madhya Pradesh.

While the rainfall will be welcome with central India now in the dry season, AccuWeather meteorologists will be monitoring the potential for any flooding downpours to be produced. This includes around Mumbai.

Rain and mountain snow is also expected to develop in far-northern India and may spread down to New Delhi.

Even if little rain falls around New Delhi, the storm system should sweep away the current haze and smog and improve air quality.

On average, New Delhi experiences one day of measurable rain in December.

For Mumbai, rainfall in December is not typical. Since the turn of the century, there have only been three Decembers when Mumbai has recorded rainfall.
