Thank you for the detailed forecast. I must say your forecasts and analysis is really good as compared to what our IMD has to offer. Keeps the readers well informed.

I had one question which I have kept pondering over. Why do we have thunderstorms at the onset and withdrawal times of the Monsoon in Mumbai? Once the Monsoon is set (June end - August end) we very rarely have rains with thunder and lightning in Mumbai. I was reading a blog on Monsoon and it says 'Monsoon rains are always convective'.

Anonymous, ur query reg. thunder activity at start and withdrawal of monsoon, reason is that this activity takes place when cold air and hot air meets. i.e the advancing monsoon brings cold air and it meets the hot air rising from the over heated land mass on its frontline. Same repeats during the withdrawal at the receding border.
