Posted 13th October Thursday Night
Technical Withdrawal Line of South West Monsoon...Images below give the explanation..
For Mumbai, though technically not in the withdrawal region, the Monsoon is as good as withdrawn...and Withdrawal for Mumbai will be announced here by 15th, as the 200 level winds change and UTH drops, along with favourable (for withdrawal) level drop of OLR .

Ashish/Hrishikesh/Sarfarajkhan: In my more than 48 years of weather observation in Mumbai, i have witnessed several years when the Monsoon withdraws " with a whimper'. ..meaning no thunder showers at all...if i remember correct, the most silent was 1968.
No thunder clouds from east due to lack of proper CAPE development and very Low humidity in the upper troposphere setting in early, with 200 winds turning before the thunder heads develop. No break period this year for heat to develop in the interiors, which again help CAPE and upwards development of thunder clouds. We have seen heated inland regions going to > 35c in the past years, with good moisture.See the images put up for this purpose.
