Currently, heavy rain is concentrated in the Far NW segment, off the Kerala/South Karntaka coast.

System will deepen into a depression in next 12 hrs, and track NW initially.

By Wednesday evening, the upper trough from WD (already dipping to 23N), and the High pressure ridge, will prevent further movement Northwards , beyond Karnataka coast. As as mentioned earlier , BB-1 should cross the Karnataka coast to move inland by Thursday.

Wednesday evening and Thursday will see very heavy rains in Karnataka, Kerala and to some extent in Goa.
Coastal Karnataka and Kerala will get downpours amounting to upto 75 -90 mms in 24 hrs (Wed/Thurs). 
Unusually heavy rains in pockets along the Goa, Karnataka coastline may bring up to 50-60 mms in 24 hrs (Wed/Thurs).

Light rains in South Konkan and Southern Maharashtra next 2 days.

M-1, after being stationary for a day, is now "pushed" Eastwards by the trough of M-2.
M-2, as a trough in the upper levels, is already formed and is over Iran. The trough from M-2 extends Southwards into the 23N region.

Next 2 days, M-2 will approach Pakistan, with precipitation in the Northern regions.Rainfall gradually increases from Thursday. Islamabad remains cloudy with light rain, but increase in precipitation from Friday/Saturday.
Friday and Saturday, precipitation extends into Sindh regions and NW plains of IndiaDelhi NCR may see showers on Friday and Saturday.

Against earlier predictions, if M-2 is moving in, it may not permit the undue heating up of the Northern Plains of the Sub Continent in the immediate next few days.

91 B will become cyclone or NOT ?

[1] The WML  is becoming deepened and may further strengthen to form as cyclonic circulation.  However as it is very closer to 5 Deg  latitude Coriolis effect will be less.  

[2] But outer feeder ring, drawn from Bay of Bengal, is passing  through Chennai and south CAP.  Similarly other outer feeder in Arabian sea passes through SIK

[3] There will be fairly widespread rain in TN.
