Hottest place in India on 29th June was Ganganagar (Rajasthan) at 43.8c.
Hottest in Pakistan was Sibbi and Turbat at 47c.

An upper air WD brought some rains to Islamabad on Tuesday ( 4 mms).Pak Punjab region will get some showers on Wednesday, after which the WD moves eastwards.

For a couple of days from Tuesday 30th, the Axis tends to shift slightly South from Punjab thru North M.P. thru Jharkhand.
Spotty thunder showers will pop up along the axis and North of it next 2 days.

To get a Low forming in the Bay, we have the trough off the East coast getting formed by the 4th of July, and as a result we may see a Low at the Northern end of the trough off or along the Odisha coast around 5th July.

Heavy rain can occur in some places in West M.P. on Tuesday and possibly Wednesday. Showers will be seen in Ujjain and Indore on Tuesday and Wednesday.

Mumbai will be hot, but may get the localised thunder shower in some parts on Tuesday/Wednesday.

Nothing much to change from the post below.....Break Monsoon conditions continue. The axis remains in the foothills of the Himalayas, and the rains continue now in Nepal, Sikkim and North Bengal.

Hotter days have started in Delhi NCR, with Palam touching 41.6c, Ayanagar 40.7c and Safdarjung 39.0c on Sunday. Amritsar was hot at  41.4c and Jaipur was 40.6c.

-----------------------------------------------------------

Posted Saturday Night:

-The Monsoon axis has shifted North to the Himalayan Foothills, thus creating a "break monsoon" Scenario.
-According to vagaries, the Winds and OLR show the Monsoon is yet to move into Rajasthan.
-Vagaries feels that with the Seasonal Low pressure now (Saturday) on a high at 998 mb, it is difficult for the Monsoon to move into Rajasthan not at least in the next 7 days. The seasonal core may drop to 994 mb by mid next week.

We see days getting hotter in the Sindh Pakistan region along with Rajasthan, Gujarat, Haryana and Delhi in the next 5 days.
Ahmadabad, with almost no rains, seeing days rise to almost 39c. Delhi may also see hotter days at 41/42c next week.

The West coast off shore trough remains weakish, bringing little rains in the next week (Next 5 days) to the West coast and almost dry for Gujarat.

The UAC in W.Bengal soon merges and dissolves in the Axis ...Rains likely in Bihar and East U.P. next 2 days. As rains will be effective in Nepal, we may see some downstream flooding in Bihar.

No organised system in Bay till 4th July at least.

Mumbai will be hot and parly cloudy, with sunny spells, and days rising to 33/34c on Sunday.Though next week, is hot and not much rains, Mumbai may see a localised convective thunder shower on Monday or Tuesday in some parts.

Kolkata, will be hot also around 36/37c, but may get a thunder shower by Wednesday or Thursday ( An embedded UAC in the eastern trough: temporary).

Pakistan remains hot and dry..(except for extreme North)....Days hot in Sindh , with peak temperatures touching 48c in Sindh and Balochistan.
Karachi will be sunny and dry, with Sunday /Monday touching 39/40c again. But sea breeze setting in next week will lower the days to around 36/37c.

Islamabad will be partly cloudy, and hotter next week. Mid week may see around 41c. Gujrat (Pakistan) will be very hot next week, touching 44c and warm nights at 33c !...before thunder showers cool down the city by Thursday..

---------------------------------------------------------------------------------
Posted Saturday Morning:

The Monsoon Axis has shifted North, running from Punjab thru U.P. and then into a Low pressure in Bangla Desh.
In view of this, the Westerlies are blowing South of the axis, and Easterlies in the North.
As a result, South West Monsoon has now covered all the regions , except Rajasthan (according to Vagaries) , as the Seasonal Low prevails over Pakistan.

The weak off shore trough of the West Coast hold good for next 2 days.
The west coast will get weak medium rains (weak as per the normal at this time) next 2 days.
Spotty rains likely in Odisha and adjoining W.Bengal, and adjoining East M.P.
Rains expected in Utterakhand, H.P, Northern U.P. adjoining Nepal and in Nepal.

Mumbai will have partly cloudy skies with sunny spells and few passing showers. Similarly, very little rains for Delhi and Kolkata.

Will put up more details tonite by 10.30 pm IST. (There was a break in my posting also :-)

Medium, heavy and very heavy rainfall expected over different parts of Saurashtra, Kutch, South Gujarat and North Konkan. Squally winds expected .

Posted Tuesday Morning

As a sudden change of directional track, AS-2, A depression in the Arabian Sea, has moved Eastwards in the previous 6 hrs. Post mid night (Monday), the system suddenly took course towards East ( tracking along with an upper air trough), and moved from 67.7E ( Last Night) to 70.1E by Tuesday morning....Vagaries of the Weather !!

System can now take a NE or E/NE course, and most likely strike the south Saurashtra coast within next 12-15hrs. Due to land proximity, it may not deepen very much now.
On crossing land, it will weaken.Strong winds and thunder showers likely along south Gujarat coastline and Saurashtra coastline. Dwarka, Porbandar, Veraval will have major impact.

In a sudden change of weather, Mumbai got strong gusty winds and thunder showers from 4.30 am  Tuesday, gusting to 54 kmph and periods of intermittent heavy rains. By 8.30 am, Santa Cruz had recorded 89 mms , creating a new all time high for June by touching a total 1039 mms. Colaba manged 70 mms.

Posted Monday Night:

AS-2 is (almost) stationary since our last posting at 19.9N and 68E. Core pressure estimated at 990 mb. Completely surrounded by moist and saturated air, and with favourable shear, system can deepen to 988 mb and now move Northwards next 12-18 hrs. Likely to cross the coast near the India/Pakistan border on 24th and move NE thereafter.

Moderate (Medium to heavy) rainfall is likely in all regions of Gujarat next 2 days. Heaviest falls in Western Saurashtra and Kutch on Wednesday 24th. 

Heavy falls  likely in Southern coastal Sindh and Karachi from Tuesday night. Central and Upper Sindh get thunder showers on Tuesday and Wednesday in many places. 

Interaction with WD and Moist East Monsoon winds will increase rainfall in Northern India and Pak Punjab after Wednesday 24th.

Ahmadabad will see rainfall increasing from Tuesday night, with Wednesday 24th and Thursday 25th  getting good showers, some heavy in the region and district. Very windy from Tuesday night or Wednesday, with winds around 40 kmph. Thundershowers may be heavy on Wednesday night or Thursday.

BB-1 has weakened, and now lies over North Chattisgarh as a Low. Since it is in the axis , embedded, we can consider it has merged now.

The Eastern Vidharbh region got good rainfall today, with Nagpur getting 53 mms and Washim 30 mms in the 12 hrs ended 8.30 pm IST Monday. 

Heavy rains were also recorded from East M.P. and Chattisgarh. Raipur saw 111 mms as on 8.30 am IST Monday.

As per Monday's showers forecast for Surat, the city received 40 mms till 8.30 pm Monday. Seeing Tuesday and Wednesday with regular showers with increasing frequency.  Estimating around 25 mms per day. Would also estimate increasing showers next 2 days in Bharuch.

South West Monsoon Moving into Gujarat, U.P. (See Map alongside for current Monsoon Updated Limit).

Monsoon expected in Delhi on 26th June (including H.P, Haryana and Punjab).

Mumbai Santa Cruz has reached a total of 954 mms as on Monday evening. The highest ever June total for Scruz is 1037 mms in 1971. 

Colaba has totaled 763  in the same period. The highest ever June total for Colaba is 1208 mms in 1985. 

Next 2 days, Tuesday and Wednesday, I would expect showers in Mumbai, shorter duration, but heavy at times. Not prolonged. Next 2 days, would expect around 75-90 mms cumulative.

Rainfall gradually increasing in Kolkata from Wednesday..

Monsoonal Precipitation in Delhi NCR from 25th, as Monsoon advances around 26th....and first day may see phenomenal heavy rain.

Mumbai was very close to our estimate for Saturday/Sunday cumulative rains...recording an average 0f 230 mms against estimated"around 200 mms"..Santacruz totals 950 mms from 1st June...nearing the all time June total of 1037 mms in 1971.
Mahableshwar saw 366 mms in 24 hrs ended Monday morning...more figures coming from Pradeep, our Rainman !

Posted Sunday Night:

BB-1 has crossed the Odisha coast, and as anticipated, poured heavy rains in the State. Many Cities in Odisha got heavy rains on Saturday and Sunday. Amongst them , Umerkot 207 mms, Malkangiri 206 mms, Udaygiri 158 mms,  Junagrh 135 mms, Jeypore saw 132 mms, Mahendragarh 131 mms, Gudari 127 mms, Gopalpur 113 mms, Jalpatna 108 mms,

South Chattigarh was informed of heavy rains as Jagdalpur measured 151 mms.
Adjoining Vidarbh and M.P. .Sunday rains in the other surrounding Cities:
Nagpur got 45 mms overnight and another 33 mms on Sunday till 8.30 pm. Indore received 59 mms on Sunday till 8.30 pm. 
Heavy Rains expected in Vidarbh and adjoining East MP on Monday.
Pune too had a wet day with 35 mms in the day on Sunday.

AS-2 (Erroneously, Vagaries had numbered this system as AS-1 in last posts. Regret the error) is now deepened , but practically stationary at 19.9N and 67.7E as on Sunday evening. Now having a core estimated pressure at 992 mb, and classified as Well Marked Low by IMD, system will deepen more, to around 988 mb next 24 hrs...South Quadrant winds, supported by Monsoon winds , are strong at around 45-55 knts. Cloud cover is mostly in the  West of the system.

AS-2 is now having strong ultra moist air is already enveloping it, and no shear resistance, it will track initially NW. After being stationary for another 12-18 hrs, it will track initially NW, and then after 18-24 hrs move Northwards. Would expect the system to meanwhile deepen to a low of 988 mb, and just weaken before crossing land around the International Border (India/Pakistan).

Coastal Sindh and adjoining Kutch can get showers on 23rd/24th , with heavy falls in SE Sindh and Kutch on 24th/25th. Inter action with Northerly trough with the upper axis will also bring showers to rest of Sindh from Monday, possibly increasing on Tuesday and Wednesday as AS-2 moves inland. Hot spots like Larkana and Jacobabad and Upper Sindh will get some relief thunder squalls possibly from Monday night thru Wednesday.
Showers expected in Karachi on 24th and 25th. Karachi is extremely Hot at 45c on 19th June, with 20th again touching 44.8c. Minimum 21st was a gruelling 33c !! Read more in Vagaries Pakistan.
Turbat in Pakistan was hottest at 48.5c.

Mumbai Colaba got 32 mms, Vagaries 33 mms and Santa cruz 49 mms on Sunday in 12 hrs ended 8.30 pm IST.

Mumbai City is not going to be directly affected by the system AS-2. As the system tracks, the SW winds will weaken marginally, not strengthen.
Hence, Monday Tuesday, Mumbai can expect frequent showers, some heavy but with limited duration, not prolonged. Accumulated rainfall for Monday and Tuesday will be around 100 mms...
As on Sunday morning, Vihar Lake received 140 mms, Tulsi 120 mms, and Vaitarna, Tansa and Middle Vaitarna 20 mms each. (Figures are rounded to mms).

Surat, will see some showers on Monday with cloudy skies, around 15 -20 mms. Rains marginally increasing on Tuesday night thru Wednesday. 

2nd day of Massive Rains in Nilgiris, Tamil Nadu Rainfall ending 8.30 am on 21.06.2015

UAC in the Arabian Sea SW of Gujarat coast also persists...Now descended to 850 mb level.

Mumbai : .as the UAC Deepened, we see a strong gush of SW winds at all levels (upto 700) hitting the North Konkan Coast. We also get Vagarians reporting heavy rains in the Northern Outer Townships like Mira Road. 

Thursday saw more rains than estimated..83 mms average in 12 hrs...Expecting another average of 40 mms Thursday night.would bring an average of 125 mms by 8.30 Friday for Mumbai.( seeing the vast area Mumbai covers, we take an average of Colaba and Scruz readings.)

The Movement and behaviour of the Arabian Sea UAC will directly affect the Mumbai weather next 3 days...but, as current indications show...A wet Weekend
Friday/Saturday/Sunday Mumbai may see very frequent intermittent heavy showers, with gusty winds. I would put a cumulative average rainfall of around 190-210 mms (for Friday/Saturday/Sunday).

A low pressure, BB-1, has formed off the Odisha coast in the Bay. It is estimated at around 998 mb initially. Expected to move NW and merge in the Monsoon Axis.

An UAC has also formed in the Arabian Sea South of Gujarat, at the 500/700 mb levels. This UAC, is expected to descend to sea level and maintain a circulation at the upper levels also.

The UAC in the Arabian Sea and the BB-1 with its associated UAC will form an upper air monsoon axis running West-East between the 2 UAC's.
The Sea Level Monsoon axis (Currently roughly along the Monsoon progress line) is now expected to move Northwards. 

The South West Monsoon is moving into Gujarat state, Southern regions of M.P., Chattisgarh., and central Odiasha. These regions will see the Monsoon advance on 18th June in totality.
Very heavy rains are likely in Odisha, Coastal A.P.  on Thursday and Friday. Potential of very heavy rains in Telengana and Vidharbh on Saturday and Sunday.

The Monsoon will move into Bengal (Kolkata), and rest of M.P, and Odisha around 19th/20th June.

The West Coast trough will strengthen and will have the UAC at its Northern tip by 19th June.
Persistent gradient, and tilting lower with height, a Low will form in the Mid Arabian Sea almost W/SW off Gujarat State by 20th.

Posted Wednesday Afternoon:

An UAC has formed in the Bay off the Odisha coast at 700 mb level...Expected to persist at that level, while descending to Sea level as a Low ( BB-1) by Wednesday Night.

The upper level trough at 700 level extends Westwards from the UAC to the Arabian Sea ...We can expect another UAC at the Western end of the upper trough W/SW or maybe S of Gujarat in the Arabian Sea.
This will be the Northern tip of the already strengthening Off Shore Trough ( West Coast). The strengthening is seen as the isobars are dropping, the 1000 mb bar now over Mumbai, and 1004 mb bar over North Kerala.
