Thursday, October 27, 2022
Tuesday, October 25, 2022
An attempt at a brief Summary of the NEM.
Vagaries predicts its advance by the 27th. taking into considerations the withdrawal of the SWM. The SWM lingered on till 23rd October
The overall delayed actions, beyond forecast estimates, is mainly attributed to the stubborn SWM, and to some extent the weak MJO not "supporting" the fast formation of NEM currents in the Bay.

Monsoon withdrawal from Mumbai, Pune and north Konkan delayed till 20th October...now seems final.
However, a cyclonic circulation in the Arabian Sea is likely to push moisture northwards towards north Konkan and up to south Gujarat on 16th/17th/18th October.
Mumbai, Navi Mumbai, Thane also have a chance to witness rain/thundershowers on 17th/18th. Monsoon will be over after 20th.
Monsoon was on track to withdraw from Mumbai and neighbouring regions by 17th/18th. (Weather vagaries and Nature is forcing us to make frequent changes😡)
Pune city and outskirts can also receive thundershowers on 17th/18th.
Thunder Showers in Ghats of Nashik/Ahmednagar/Pune districts on Monday 17th and Tuesday 18th October.
Marathwada areas of Aurangabad, Jalna, Beed, Nanded, Latur could receive rain/thundershowers in parts from Sunday 16th to Tuesday 18th October.
Parts of Vidarbha (Akola, Amravati) districts can also get some rain from 16th-18th October.
Along with a trough like feature in easterlies at 850 hPa, this can trigger rain/thundershowers across parts of South Gujarat (Valsad/Navsari, although chance is less).
Forecasted surface winds and Relative Humidity for 17th
After SW Monsoon withdrawal from North Konkan, entire North Madhya Maharashtra, Vidarbha and Marathwada, dry easterlies (and October heat for Konkan) could set in from 20th/21st October.
Bay of Bengal witness frequent cyclonic circulations as easterly Waves, normally anytime after 15th October. This is precursor of onset of Northeast Monsoon.
We expect a Low to emerge in the Bay around 17th...and feel North East Monsoon will resultantly set in around 21st...Simultaneous to SWM withdrawal.

FAQ Reg:Gujarat Circulation
Weak circulation seen over Saurashtra region (see image on the right) is from the cyclonic circulation which was present near north konkan 2 days back.
This is bringing moisture from Arabian Sea and heavy unseasonal rains over parts of Saurashtra (Junagadh region).
It can persist weakly, and a upper air trough may form over Gujarat thru South Rajasthan. Hence chance of patchy rain and thundershowers remains till Wednesday 12th October.
Gujarat region of Ahmedabad/Gandhinagar, Vadodara, Bharuch may see some cloudiness with chance of light rain in some areas during this time.
Dry weather expected after 12th October with SW Monsoon withdrawal from south Gujarat regions.

Weather scenario for Weekend 8th October to 13th October
Rainy weather for north and west India!
Rainfall likely in east Gujarat (Ahmedabad, Gandhinagar, Vadodara, Bharuch regions) and parts of south and east
Rajasthan tonight and tomorrow.
A cyclonic circulation seen at 850 hPa over north Maharashtra causing moisture inflow from Arabian Sea, resulting in rains and delaying SWM withdrawal.
850 hPa winds
7th October Evening 6pm.
The thundershowers in Mumbai today is not unusual or alarming.
As the movement of the low pressure system BB 14, moved across Central India, it has activated rainfall in Mumbai and Gujarat.
This resulted with an interaction with a Western Disturbance trough from North India. Hence the thunder.
This system activation was expected, and Monsoon Withdrawal date declaration held back ( see previous post).

Posted on 2nd October Evening:
Mumbai: The last 3 days of the Navratri celebrations...and how is the weather going to play along ?
Hold on Monsoon still lingering.
This week ( 3rd Monday to 6th Thursday), Mumbai will see partly cloudy skies. But a few moderate (and sharp intense) thundershowers are likely. Rainfall around 10-25 mms/day variation expected. Occurrence of the showers would be in localised in different areas of city. Possibility of an evening shower on Dussehra holds good.
Pune: also can see some light to moderate showers in the late afternoons. expected rainfall in parts of city around 5-10 mms.
For both cities, we hold on the further Forecast, as a dim chance of rain continuing into weekend holds good.
Marathwada & Vidharbh will get light to moderate rainfall this week 3rd onwards. Around 10 mms/day. Few places rain may exceed 20-30 mms/day from 5th Wednesday
Farmers are advised to cover the crops if already cut and removed for storage. As wet conditions may spoil the cut crops.या आठवड्यात मराठवाडाआणि विदर्भ हलका ते मध्यम पाऊस पडेल. सुमारे 10 मिमी/दिवस. शेतकरी आधीच कापलेली आणि साठवणीसाठी काढलेली पिके झाकून ठेवू शकतात. ओल्या परिस्थितीमुळे कापलेली पिके खराब होऊ शकतात. काही ठिकाणी बुधवार 5 ऑक्टोबर पासून 20-30 मिमी/दिवस पेक्षा जास्त पाऊस असू शकतो.
BB-14 moving towards the UAC, and could merge as explained earlier.
But, its further movement after crossing the A.P./Odisha coast should be NW.
Interacting with W.D, there will be some rains in Central India, Bihar, U.P. Uttarakhand (East)and .Affecting upto Nepal..
We expect possibly some post Monsoon showers in Delhi this weekend.
Keeping in mind the above scenario, we hold on to the withdrawal line for a few more days.
