Rajesh Sir : From Monday to Thursday thunderclouds were forming in east & clouds movement were from east to west..

But today SW/W/NW gusty winds blowing and clouds direction also changed as now alto cumulus clouds coming from SW and moving towards NE.

So is it due to The trough in easterlies extends from southeast Arabian Sea to northeast Arabian Sea !!

Also now most of models forecasting some chances of rain for Mumbai for tonight & tomorrow morning !

So whether Vagaries predicting the same or sticking to yesterday's Mumbai forecast only of : Partly cloudy Friday. Clearing from Saturday !!

abhijit: Good observations..ok, charts of 0900 hrs UTC Friday, and 1200 UTC fFriday show the low in the North now as an extended low. The Low isobar circles from North Raj to South Gujarat to MP. It is extended in the Raj/Guj /MP region at 1010 mb.
Now, as the winds are anti clock wise, the SW winds commenced in the N.Konkan region to circle the low, and N winds came down the Western edge of the low ,where Shitij marked North winds in Surat.
Also abhijit, please note the Mumbai clouds are flattening.So atmosphere is stable on the upper level..

rkjrdp: you have removed your comments for some reason..but gald to note Chennai getting rains as predicted.
Thanks Tyrone for the Karachi feedback, yes, we had expected rains there too
