It can be mentioned that things and sequence have almost fallen in place till Monday..Record rains for Nasik getting 37.2 mms in 24 hrs ended Tuesday morning, the highest ever for a February day.. beating the previous 16.5 of 1968 by more than double. Rest of N. Maharashtra got rains with Jalgoan 21 mms.

However on Tuesday, the weak low which was east of Mumbai, moved NE into MP and onwards towards UP(expected movement was to the North)..spreading clouds and meagre precipitation into rest of MP and UP. It would be correct to say it has very tactfully avoided Delhi !
It has "flattened" out into a "mini trough" at 25N (MP/UP)
The trough, roughly along or just below 25N next day, forms a weak low in South Rajasthan and MP border on the Thursday 14th. On Friday 15th, the low should move North into North Rajasthan.
detailed forecast in vagaries..
