Seems to be right so far; was their any signal/signals in the extended range scale which could have given us some indication about this?

The rapid pace with which the southwest monsoon current is advancing this year could even set a record for covering the entire country at an earlier most date, in our recorded history.

Weather charts of 17th show a northward shift of the monsoon trough specially the western end leading to a break situation the withdrawal could start once the system over Jharkhand becomes weak

Charts of 14th September ( surface ) show a very slack pressure gradient over the west coast Rainfall over Western Maharashtra has reduced .Appears to be early signals of withdrawal

A revival in the monsoon activity would occur towards the end of July. The low level vorticity contributed by the horizntal wind shear will become conducive for the formation of a low pressure area over the Bay of Bengal, subsequent to the westward movement and weakening of the Typhoon (Nock-Ten) over the west Pacific. Currently the Typhoon is tracked westwards and forecast to move further westwards along 20 deg.N. The remnent vorticity would contribute to the low level convergence over the Head Bay around 1st August.

The seasonal trough which was lying close to foothills of Himalayas for the last four days has finally shifted southwards. There is also feeble cyclonic circulation over west central bay. This suggests that the break phase of the monsoon is over. However, meteorological conditions do not indiate strong revival as no low pressure or depression is developing in the Bay of Bengal. Nevertheless, the rain deficient areas of north Andra Pradesh, Maharashtra and Gujarat may get good rainfall activity in this spell. This means that the all India rainfall may remain on negetive side for the next one week.

The eastern end of the seasonal trough shifted southwards and dipped into the head Bay of Bengal. However, the western end of the trough is still continues to run close to the foot hills of the Himalayas. Current meteorological conditions are indicating that the western end of the seasonal trough will also shift southward during next 48 hours. This will lead to revival of monsoon with increase in rainfall activity over east, central and adjoining north peninsular India during next 24 hours.

Synoptic Features The low pressure area now lies as a low level CYCIR extending upto 700 hPa, over central Uttar Pradesh. According to IMDGFS and IMD WRF models, the system is likely to weaken in the next 24 hours, and persist as a east-west trough line in the lower atmosphere in the same region for the next 2-3 days. The trough of low pressure on mean sea level chart has moved slightly northwards and now passes through Punjab, UP and Bihar. GWB and thence southeast wards to North-west Bay of Bengal. The eastern part of the trough has split, with one branch passing southwards through GWB into the north Bay of Bengal, while the other branch moves through SHWB, Bangladesh, Assam. A weak Western disturbance approaches northwest India. Due to interaction between the easterly and westerly wind flow in the lower levels, weather is expected over Northwest India, Madhya Pradesh and East Rajasthan in the next 3-4 days. The offshore trough along west coast likely to persist during next 3 days.
