Posted Sunday Night: 

Mumbai: Monday 6th/Tuesday 7th/Wednesday 8th: Partly sunny to cloudy skies. A couple of passing showers in some areas will bring much needed relief. But, rain amount may not exceed 5-7 mms per day. stuffy nights continue.
Interior regions of Maharashtra (Madhya Mah, Marathwada and West Vid) will remain practically dry without meaningful rainfall till next 4 days.

Synopsis:
Currently Hot and very hot days in the entire region...5th July...In Pakistan Moen jo Daro 47c and Larkana 46c....and Sri Gangannagar at 40.7c and 40.6c at Palam (Delhi). in India

The Monsoon axis is stubbornly fixed in the North, and the fresh WD ( JL-1) is preparing to proceed, come what may !

Time-series representation of the Summer Asian Monsoon OLR Index (SAMOI-N) indicating the meridional shift of the active convection area to the North
The OLR index (SAMOI-N) indicates the meridional shift of the active convection area associated with the Asian summer monsoon. SAMOI-N is defined as the difference between the reversed-sign area-averaged OLR anomalies over the area from northern India to northeast of the Philippines (shown by the area enclosed by the solid green line on the bottom) normalized by the standard deviation and those over the area from the central North Indian Ocean to southeast of the Philippines (shown by the area enclosed by the dashed green line on the bottom). Positive and negative SAMOI-N values indicate northward and southward shift of the active convection area, respectively, compared to the normal (i.e, the 1981 - 2010 average). The thick and thin green lines indicate seven-day running mean and daily mean values, respectively.

Monday 6th: As mentioned on 1st July, the Inter Action of WD ( JL-1) with the Monsoon axis starts from Monday 6th July. Northern Indian States of Punjab, Haryana, H.P. and Utterakhand get good precipitation on Monday 6th July. 
As the day proceeds, rains become heavier by afternoon /evening in Indian Punjab, adjoining Haryana, West U.P. and Uttarakhand. Spill over into North Rajasthan possible. U.P. regions East of Delhi (Barielly) will be receiving heavy falls. Adjoining East M.P. can get showers also as the entire axis line is prone to rainfall.
Delhi NCR starts getting showers from Monday evening.

Tuesday 7th: Monsoon entering Northern Pakistan.
More concentration of heavy rains on Tuesday (more likely as the day progresses) in Pak Punjab. All regions in North Pakistan get heavy showers. 
Gujrat (Pakistan) gets showers on Tuesday, amounting to around 15-20 mms on Tuesday. 
Heavy falls in Nepal. Heavy rains also possible in Sikkim, leading to overflowing of local rivers downstream.
Rainfall in Indian NW regions may be a little less compared to Monday. 

Delhi NCR will be cloudy with showers interspersed in the day. Around 30 mms Tuesday day and Night.

Wednesday 8th: The entire stretch from Pak Punjab thru Indian Punjab, Haryana, U.P, Uttarakhand and North Bengal get moderate rains. 
Delhi NCR may get less rains also, but the intensity will be more on Thursday again.

 From an already formed UAC,a Low ( BB-2) forms in the North Bay of Bengal on the 7th. 
May concentrate in WML and maybe depression (992 mb), before crossing Odisha coast around 10th. But strength and Track depends on WD trough behaviour. 

If JL-1 can bring down the Monsoon axis to the South near Rajasthan, then this BB-2 can possibly track West wards. If the persisting WD trough extends Eastwards, the BB-2 may head North. Vagaries is unsure of the track today.

West Coast trough remains weak next 4 days. Slight movements continue (seasonal). A "spurt" ...
1). In off Karnataka/Goa region will see increased rains in Goa on 7th and 8th. Maybe around 40 mms/day...and 
2.) in the Northern end may bring some light rain relief to Saurashtra for a day on Tuesday/Wednesday.
Strong SW winds will continue in Saurashtra and Coastal South Gujarat next 3 days.
But most of Sindh (including Karachi) will remain practically dry and hot.temperatures may shoot to 46/47c next 2/3 days.

Chennai will continue to be very hot, around 40c next 2 days, with no meaningful rains till Thursday at least
Kolkata: Oh Calcutta ! And it goes on..Thunder showers again on Monday and Tuesday...around 15-20 mms average.

All Major and Minor reservoirs of Marathwada have a total live storage of only 7% as on date. 
Jayakwadi has only 1% storage, and Lower Terna, Majalgaon and Manjra reservoirs 0% !  

As the reasons were explained, rains were seen in the Eastern States of Odisha and W.Bengal, and NE last 3 days. And weak monsoons elsehwere.( Monsoon will be weak for a couple of days now in East also).

Monsoon remains weak in the Peninsula next week also. But as mentioned in the 1st July Post, Point no. 4), a WD will bring rains to Punjab (India and Pak), and to Kashmir, H.P. and Utterakhand. Nepal will benefit from the inter action of WD and Monsoon axis. All this from 7th July.
Point no. 5 of 1st July post holds valid, and S.W. Monsoon may move into Rest of Sindh and Pakistan from 7th July.

U.K's Hottest July day ever...and Western Europe Heat wave ...see International Page
New Delhi: Palam touches 40.3c and Gurgaon 40.0c on Thursday...S'Jung 38.9c.----------------------------------------------------------------------
Posted Wednesday Night:...1st July

How is the South West Monsoon going to behave in July ?


1. MJO: the current phase of very weak MJO in our seas is prevalent, and with a slight "blip" in the Northern region seen thru OLR images, we see the Northern Bay showing signs of of a UAC formation soon. UAC may effect Eastern States of India and the NE States with precipitation in first week of July.


Rains increasing in Kolkata from Sunday 5th.


But the weak MJO phase ( Though gradually moving out of the very weak phase) in the Southern seas continues  and without any Eastward propagation for the next 10-12 days.

Long Term forecasts show the MJO "improving", that is first getting "Neutral" by around 14th July, and then gradually strengthening after 17th July.

As a result, we have a strong MJO wave in the Western pacific. We may even see a typhoon form in the Western Pacific next week.


2.El Nino: This event has strengthened in the last 15 days. SOI is at -9.0. and the Central and eastern tropical Pacific Ocean sea surface temperature indices are more than 1 °C above average for the sixth consecutive week.


3. The Monsoon axis remains North of its normal position till the 8th at least.Rains expected in Eastern U.P, Bihar and Sikkim and Himalayan W.Bengal next week.


4. A WD moves into the Northern Sub Continent around 6th July. This would merge with the Western end of the Monsoon axis and bring good precipitation to Northern Pakistan and Northern India.


5. Next 8-10 days, Precipitation remains lower than normal in the Peninsula, Western Region, Central Region, NW region of India. Also in Central and Southern Pakistan rains will be below normal. Monsoon may move into remaining Sindh and Pakistan after 7th/8th July.


Monsoon remains weak in the Sub Continent (barring Eastern states of Odisha/Bengal and NE India. Barring extreme North Pakistan) in the first 15 days of July. Strengthening in the second half will see the rains recovering in the regions.


For All India, i would expects a 10% shortfall overall for July only. The current +ve figure of +16% would therefore fall.


Next 5 days in....

New Delhi: As the next 2 days get hot, maybe around 40c, we will see an increase in showers by Sunday and Monday.

Mumbai remains hot and cloudy, around the 33c-27c range. With no major rains developing till Sunday. Around 3 - 5 mms per day.


Pune remains in the 30-23c range till Monday, with light drizzles in some parts.


Aurangabad till Monday, remains dry and hot at around 34c, with minimum at 23c. Light drizzles in some parts.
