Monsoon Axis moving Northwards. Along the North Rajasthan/North MP, UP line.
As the line moves up, precipitation expected again in the Hill States.
The West Coast trough weakens, in fact chart shows it is almost gone, with "ridges "forming along the coast.
The East Coast trough persisits due to the Eastern end of the axis remaing in a "low" loop.
Not yet confirming about the low announced by IMD...shall make a statement when sure of it..

Mumbai Observations (for Mumbai Readers):
Just yesterday, i had seen huge cloud tops forming. On personal observations today evening (Tuesday), i saw the clouding over the Western sky over Mumbai getting into a "flattening" mode. That means, as per what i saw, around 50% of the clouds were strato -cumulus, not developing or rising. Though there were some moderate rise in some clouds, the rising "trend" was reversing, to some extent. This indicates a stable upper atmosphere condition developing. 
This is an initial observation, and the tendency of cloud formation has to be followed up. In cases like this, in this season, things can change again in a couple of days.

Dear GSB,
What you have given is 100 years data perhaps from IMD. This is IMD format.

GSB said...

Anon,

I'm not sure if it is from IMD. I have not seen the main IMD site having data of individual cities.. maybe if they have I have missed it all these years..

The file I had on my computer was named Bangalore and therefore I presume it of that city itself. Even the data totals suggest that it is indeed of Bangalore due to the average rainfall of about 80cms.
