29th September

South West Monsoon Withdraws from Punjab, Haryana, Delhi and Rajasthan, exactly on 29th ( indicated few days ago in Vagaries). {also confirmed by IMD today}

The withdrawal Line 👇


The Mentioned BB-14 is positioned as shown below 👇, will emerge in the Bay around 1st,and later will merge with the UAC...


Mumbai/Pune: Thunder Showers expected this weekend..30thSept/1st Oct/2nd Oct.

Tuesday, September 27, 2022

27th September Night:

The UAC ( shown in 25th post Image), will on September 28,  be over parts of West Bengal, Odisha, and some parts of North Coastal Andhra Pradesh and  partly over sea. It will almost be over the same region and not show much movement.

Cotinuing from our Snippet shown here..👉

A Typhoon, Noru, has already formed over the South China Sea and will weaken as it crosses the southeast Asian countries of Laos, Thailand, Vietnam, Cambodia etc. Thereafter, it will emerge in the Indian waters, almost merging with this UAC.

NORU 👉 

Hence, on October 2nd/3rd, another system , BB-14  emerge in the Bay. 

As it is now the Withdrawal time, and 200 hp Streams and anti Cyclones resistances are present, BB-14, the systems from the Bay,  will  not reach out far too Westwards. May just track N/NW, into East Indian States .



SWM withdraws from Rajasthan, Punjab, Haryana and Delhi as targeted on 29th.




Mumbai: As already forecasted, we saw almost rain free days, and totally rainfree evenings on 26th and 27th, adding delight to the celebrations...A little hassle from 29th- 1st October ,as Mumbai can see thundershowers in the evenings, and play spoilsport.

Pune will witness showers on 28th,29th and 30th in the evenings.

Bharuch/Surat  will see light rains on 28th, 29th and 30th. May not spoil the festivities.

Sunday, September 25, 2022

25th September Evening Post:

South West Monsoon likely to bid goodbye from Punjab, Haryana, Delhi and Rajasthan by Thursday 29th/ Friday 30th September.

Now, rain activities will reduce significantly over Northwest India including Punjab Haryana Delhi and western parts of Uttar Pradesh. 

An anticyclone is expected to develop over southwest Rajasthan by September 27, and northwesterly dry winds will commence over most parts of Northwest and Central India.

Seasonal Rainfall (in mm) since 01 June 2022 till 25 September 2022 EAST & NORTHEAST INDIA  -17% ,  

NORTHWEST INDIA  +1% 

CENTRAL INDIA +19% 

SOUTH PENINSULA INDIA  +24% 

COUNTRY AS A WHOLE 909.3 mms (Actual) .. 848.5mms ( Normal) +7%

Currently, the Country as a whole is in Surplus by +7%.   

But N.E, Jharkhand and U.P.are in deficit. These states can recover if the UAC in West Bay tracks N/NW...

 21st September



Cool and Pleasant Weather along Mumbai Area last 3/4 days...Due to 

A Stationary Front block...

Fronts refer to the boundaries between air masses, which are large, discrete atmospheric bodies of unified weather characteristics. If a cold or warm front halts, it becomes a so-called stationary front.

See the weak flow off the Mumbai coast in the Wednesday lower winds Image

Stationary Front Basics

A stationary front is an unmoving one, at least near Earth’s surface. Neither abutting air mass has the power to shove through the other. Such a front may form when upper-level winds that had previously propelled a front along shift and flow parallel to it, or where air masses equally matched stall one another’s movements. Even though the surficial front may be basically stable, air may be significantly moving about higher up in the atmosphere. A stationary front can eventually dissipate, or, given a shift in upper-level winds or the relative strength of one or another of the air masses, might resume mobility as a cold or warm front.

Typical Weather

The exact weather of a stationary front depends greatly on the characteristics of its constituent air masses -- their moisture levels, for example -- and the general instability of the local atmosphere. Often, however, conditions resemble those encountered along warm front weather: extensive cloudiness and showers. As a stationary front can be durable, such overcast and moderate precipitation may persist for days. 👇

Surprised at the current Mumbai Drizzles ?..there is a reason to be...This could happen more in winter, after a front...Vagaries of the Weather...not any trough, Low or Vortex !

Aside the normal conditions, we got surprise drizzles of various intensity in Mumbai,contrary to expectation, formed due to the extensive humidity contains in the regional atmosphere...

Drizzle is a light liquid precipitation consisting of liquid water drops smaller than those of rain – generally smaller than 0.5 mm (0.02 in) in diameter. Drizzle is normally produced by low stratiform clouds and stratocumulus clouds.

Stratiform cloud may form during a warm front passage due to the steady, continuous rain falling from nimbostratus cloud, adding substantial amounts of humidity to the air

Stratiform precipitation, in general, is relatively continuous and uniform in intensity (i.e., steady rain versus rain showers).

Shallow, stable, non-precipitating cloud. Differs from stratus in that it is broken. Stratocumulus often results from PBL(planetary boundary layer (PBL), also called atmospheric boundary layer, the region of the lower troposphere where Earth's surface strongly influences temperature, moisture, and wind through the turbulent transfer of air mass. The height of the PBL ranges from 100 to 3000 m and varies with time, location, and weather conditions-)based cumulus, that encounters a stable layer and is forced to spread laterally.



Statiform/Cumulus Clouds

Drizzle is a light liquid precipitation consisting of liquid water drops smaller than those of rain – generally smaller than 0.5 mm (0.02 in) in diameter. Drizzle is normally produced by low stratiform clouds and stratocumulus clouds.

Weather outlook for this week - Tuesday 6th September to Friday 9th September: Monsoon reviving gradually!


A cyclonic circulation in mid levels (~700 hPa) near Kerala coast expected to bring moderate rain/thundershowers along Kerala and Karnataka coasts and Ghats. 

700 hPa winds

Wind instability and the effect of this cyclonic circulation is causing heavy thunderstorms near Bangalore region and interior Tamil Nadu. This can persist for another 2 days. 


The earlier estimated low pressure area BB-12 may form in central Bay of Bengal by 7th/8th September and track west-northwest, towards north Andhra Pradesh coast. The monsoon trough which is close to Himalayan foothills, will move south towards the Bay low. This can increase rainfall for central India as well as set-up an offshore trough along west coast enhancing rains along konkan and Goa by the end of the week. 


Mumbai :

FAQ: Is the rainy season ending ?...No hurry...

We can get Rain/thundershowers in some areas, along with warm and humid weather. Rainfall likely to increase Thursday 8th, onwards 

Pune: Rain/thundershowers likely through the week, warm and humid, but turning pleasant after rain. Moderate to heavy thundershowers likely in some parts of the city and district. 

Interior konkan (Thane/Palghar districts) and Ghats have more chance of heavier thundershowers for next 2 days. 


Madhya Maharashtra belt of Nashik, Dhule, Jalgaon, Ahmednagar, Pune, Satara, Sangli, Kolhapur, Solapur districts can get moderate thundershowers. Heavy rain in some localized areas is likely. 

Marathwada region of Aurangabad, Jalna, Beed, Parbhani, Latur, Nanded to get light to moderate rain/thundershowers during this period. Some localized heavy showers possible.   

Vidarbha region to also get light rain in some parts, more chance of heavier rain towards end of the week once BB-12 moves inland. 


Heavier rain along konkan coast may possibly occur by the coming weekend, as westerlies strengthen, giving peak monsoon feel once again. 

Gujarat region may see increase in rainfall from/after Friday. 

Forecasts can change to some extent and not all places will receive well spread rainfall (given the thunderstorm nature of the rain). 

More updates as BB-12 develops. 

Monsoon withdrawal from west Rajasthan not expected anytime soon, not before mid September at least. 

Saturday, September 03, 2022

Saturday 3rd Post:

For the next week ..5th - 9th,  to see  increase in rainfall in Odisha, M.P, interior Mah , we observe the upcoming BB -12, likely to form in Central Bay around 7th.

The UAC  off Kerala is also to be


monitored...the BB -12 will strengthen the West Coast off shore trough by 8th, resulting in good rains in Kerala,  Coastal Karnataka. Goa and Konkan ( including Mumbai), next week.

This is an initial observation, more on Monday  5th with the developing situation. 

The Monsoon Axis slides South...So, a few days wait to announce the SWM withdrawal.
