Cooler days in Vidharbh and Marathwada 


The effect...24 hrs rainfall 👇


7th Night

Low-pressure BB 5  over Gangetic West Bengal is triggering widespread heavy rain IN M.P, Chattisgarh and Vidarbha. Can soak parts of North Telangana. 

Heavy thundershowers possible in next 3 days.

Nagpur, Raipur, Jabalpur, and Adilabad are likely to witness downpours, with chance  of local flooding

Current lightning 7th evening


 

Nagpur: Heavy thundershowers next 2 days, Monday/Tuesday. Cumulative  120- 150 mms in 2 days.
Decrease from Wednesday, but rainfall continue for a day more

 From Mitan Batu ( Odisha): 


Rainfall chart for upper Mahanadi basin till 8.30am 6th July 2025

Already north Odisha flooded

Interesting part is that time there was just an uac over Gangetic West Bengal that time and couple of troughs passing

6th Night Posting:

The Low in the North Bay has regenerated into Low BB 5.

Lows forming over West Bengal...the consistency of Bay lows this time over WB right from the beginning and not south Odisha/north AP is a major factor for keeping monsoon trough and shear zone feature above/north of Mumbai latitude, something which was lacking in last 5 years.



The West Coast Trough will remain moderately active.

Next week starting 7th.👇

Mumbai:

Lakes supplying water are filling up well with good rainfall. Tansa 107 mms.Mid Vaitarna 112 mms, upper Vaitarna 86 mms.

The storage today shows 59.56%.

Mumbai will get occasional showers or passing showers in certain areas. Averaging 15 - 25 mms /day.

Pune: Cool weather with light to moderate rains oft and on. 5-15 mms/day.

Sambhajinagar: Light to moderate rains at the rate of 10-20 mms/day.

Gujarat: Moderately heavy heavy in Gujarat, Saurashtra and Kutch on Monday 7th.

8th onwards rains restricted to Saurashtra and South Gujarat region.

Surat & Valsad will get occasional passing showers .

Bharuch: Light to moderate showers and pleasant day.

The South Asian Monsoon 3D Large-scale circulation is now fully established:

While,June has been an above normal rainfall period for the country as a whole with a cumulative rainfall departure of +9%, there were regional variations in the rainfall pattern with north east and southern peninsular India ending with below normal rains. 

Meanwhile, the latest sub-seasonal scale forecasts from global NWP models for the next 2 weeks indicate that the pattern of monsoon rainfall anomalies over India and the larger south Asia could be exhibiting regional differences. While the forecasts continue to indicate an active rainy spell for much of the core monsoon zone (central India) due to an active Monsoon Trough with frequent westward propagating transient lows, the peninsular India could be under the influence of suppressed rainfall conditions.

With the onset phase of the current year's South Asian Monsoon now drawing to an end, the 3D large scale monsoon circulation associated with it is now completely established as seen from the latest available observations. Several semi-permanent features like the large scale upper tropospheric meridional temperature gradient, Tropical easterly jet, low level monsoonal westerlies, large scale upper level divergence over NW Pacific, Mascarene High, Monsoon trough,etc., have all established. One can see a completely established Baroclinic atmospheric structure over South Asia. Interesting days ahead with anomalies across spatial and temporal scales that would interact with this established Monsoon background.

Mumbai: Increase in rainfall frequency from Saturday 5th.

Occasional heavy showers.
