Last two days, we have seen big mass of clouds move so close to chennai only to fade away. Some of us were thrilled and even thought that it wont miss Chennai. But in the end, it never rained as expected as the wind were not supportive and when the wind was supportive there was no moisture at all levels.
Tomorrow/ Day after Tomorrow Morning satisfies all parameter for rains, there is moisture from 6 kms to surface level and we also end up in the right hand side of the upper air trough. So, as usual, a big TS will move from Vellore, but this time it will extend into Chennai and the rains may start night /late night /after mid night. To be honest, it is very difficult to predict quantum as these TS may dump cm’s of rains in minutes.
Enjoy it as April rains are very rare and Remember Rains will start only at night or after mid night as these storms have to travel to Coast. It is also one heck of a rare system.
