Going to be a clear sky
This year unusually and fortunately the Diwali day is going to be a CLEAR sky day, however there might be some local light showers. Otherwise the forecast is good for the Festival of India.
Take a look at the latest satellite pic, and see for yourself.
Meanwhile watch out for the 1st Tropical Cyclone of the North-East season. Please see the one area marked in red.
This might become into a tropical cyclone and at this time we cannot predict the movement of it. We'll keep a eye on it.
Hope this system brings good rain for the rain scanty Chennai and Northern Tamilnadu.
Today also rain showers can be seen over west-south-west parts of outer chennai, but no rain in the center of city.

Abnormal warmth in northern India
On the Indian Sucontinent, there has been no return of cooling from the northwest and, with high pressure hanging on aloft, it has become abnormally warm (hot) over a wide area. Sunday and Monday, the temperature toyed with the 100-degree mark (38 degrees C) in Gujarat, western Maharashtra and, in nearby Pakistan, Sindh. Actually, Karachi had about 100 degrees F (37.5 C) Sunday.
One aspect of the early-month heat has been hit-or-miss thunderstorms in western Maharashtra and even Gujarat. As of today, Monday, few of these were seen, however, at suggestions from numerical forecast models are that these will be few in number, if not lacking altogether, as this week unfolds. A weak `western disturbance`, or wave in the sub-tropical jet stream, will afford a little cooling beginning at mid week.
