Classical explanation:
At last BOB-UAC coming close to the NTN & SAP coasts. So tomorrow onwards rainfall activity with overcast conditions along the coastal NTN & SAP will increase gradually. However this UAC may not be descending to lower-level, which is evident from weak 850 hpa level vorticity & stream lines (Figures 1 & 2). This UAC will start entering Arabian ocean by travelling across TN after June 4th. Overall in-between June 2nd & 4th, rainfall activity along NTN-CTN & SAP coasts will peak and expect some decent rainfall.
Figure 2: 850 hpa stream lines:
Non-classical explanation:
The recent increase in SOI & IOD values given life in the form increasing moisture filled trade winds thus stability of present BOB-UAC for longer time. However SOI started again falling down as per lasts values (decreased by 0.5 points). So present BOB-UAC may not strengthen to LPA and will enter Arabian ocean, where it will be getting good MJO-support in phase 1 to strengthen beyond LPA along the west-coast.
MJO: http://www.bom.gov.au/climate/mjo/
SOI: http://www.bom.gov.au/climate/enso/soi.txt
IOD: http://www.bom.gov.au/climate/enso/iod_1.txt
Future direction:
From the present BOB-UAC there is fair chance of decent rains along coastal NTN & SAP between June 1 & 4.
However we need to focus on next BOB-UAC (can become rain-bearing strong system) for NTN & AP by June 2nd week under the support of strong MJO entering in phase 2.
Conclusion: Expecting this June month rainfall over Chennai will end up in historical note in similar view with PJ.

good night…let us pray for wet roads tomorrow
i want flooded roads tomorrow
me too
One of the strongest thunderstorms i have ever witnessed in Jersey City,NJ.. Its pouring cats and dogs for the last 1 hour with no signs of relenting
Photos please
Any possible rain in chidambaram
Wow…it looks rainfall chances are brightening along coastal regions of NTN & SAP including chennai before complete moving of the present BOB-UAC moves interior. http://www.weatheronline.co.uk/weather/satellite/Asia/India/Infraredcolor.htm
Wow.. I contributed the topic first time, rain-god is rushing towards Chennai 🙂
Rao sir can the TS at sea will reach us by 10 am, waiting for the rain on week’s and month’s first day
actually this UAC moving very slowly towards coast, so chances will increase from tomorrow onwards. rainfall intensity will peak on June 3rd over Chennai. Expecting very decent rainfall over 100 mm before complete traversing this UAC towards west-coast.
Raoji good topic and beautifully explained.
oh superb congratulations , may your words come true
I am ready with my umbrella!!
Pre-monsoon showers relentlessly lashed the city on Sunday evening bringing down trees and electric poles
Showing no signs of abating, two rounds of pre-monsoon showers relentlessly lashed the IT city on Sunday evening, bringing down several trees and electric poles and causing chaos and traffic snarls in the silicon valley.
An hour-long shower interspersed with heavy winds and lightning around 4.30 pm along with a second, less intense bout of rain around 8 pm not only brought down more than 30 trees in various parts of the city, but also uprooted numerous electric poles, resulting in sudden power cuts. Motorists had a tough time wading through knee-deep water on several busy streets in the CBD and eastern parts of the city.
Giving an effect of late evening, thick, dark clouds swirled around the sky and engulfed Bengaluru as early as 3.30 in the afternoon, bursting into showers and pouring across the city a short while later. These were accompanied by billowing winds that sent the clouds scudding and pedestrians scurrying for cover.
In less than an hour, a huge tree near MG Road’s Anil Kumble circle fell on to the bustling road disrupting traffic. Traffic on Lavelle road was diverted as well after an electric pole and a tree fell across the road, with wires dangling dangerously.
Entry to Lavelle Road was blocked for commuters approaching from Richmond Road, and Lavelle Road itself remained impassable until traffic policemen and BBMP personnel arrived to clear the debris. Power to the areas where electric poles had fallen had to be cut immediately to ensure no untoward incidents could take place.
Officials from the Regional Meteorological Observatory told Bangalore Mirror that the city received 15.6 mm rainfall till 8:30 pm, while HAL airport witnessed 27 mm rainfall. Sources in the BBMP revealed that as many as 25 trees were uprooted in Yelahanka sub-division alone, with nearly six electric poles and trees having been reported as fallen in Yelahanka old town’s Maruthinagar.
Meanwhile, Vidyaranyapura, Chokkasandra, Jalahalli Cross, Gangamma Circle, and Neelasandra also reported a number of uprooted trees due to the heavy wind. A tree reportedly collapsed on top of a house near the Renukamba temple at Nanjappa Circle in Vidyaranyapura, but nobody was injured as the house was empty at the time of the incident.
While 39 electric poles fell in north Bengaluru, areas in and around Yelahanka slipped into darkness for more than an hour on Sunday. The Yelahanka-Doddaballapur road was clogged with four to five feet of water, and several two- and four-wheelers were damaged due to trees and electric poles that fell on them in the rain.
Mr.Rao, Chances of rain to NTN till the 2nd week of June well explained from a layman point and also technically and hopefully nature listens to these words from you and gives record breaking rains.
Great topic Rsrao sir . Congrats

Did you see radar?

Well explained topic by RSR.The surging TS fom the sea has already heralded a cloudy pleasant morning in chennai
Hi Gopal Anna ,
Really Cool morning After long time . Hope ts should reach chennai soon
Rami Rao..Pleased as a punch for you. Nicely drafted topic. What a way for things to start. June 1st..Effectively start of SWM season for India…I mean the timing of your debut topic..Couldn’t have been better..Kudos.
Awesome Ts approaching Chennai On the east 🙂
@ramisettisrinivasarao:disqus
Excellent Topic sir , Hope Your topic Should Bring Rains
looks like rainfall activity peaking on june 3rd, where 850 hpa also showing CC right over Chennai according to GFS.
What is tht direction of Ts in the sea
Chennai might missed the TS
If it doesn’t weaken it might head towards Pondy
Thanx my native place is pondy but I wany rain in chennai
Chennai will have better chance tomorrow or day after
according to both agencies SOI slightly increased. This clearly tells SOI almost stabilized. So present UAC won’t weaken without giving rains for Chennai before entering Arabian ocean.
BoM SOI: http://www.bom.gov.au/climate/enso/soi.txt
longpaddock soi: https://www.longpaddock.qld.gov.au/seasonalclimateoutlook/southernoscillationindex/30daysoivalues/
Great topic Rao ji ! 🙂 Clear representation of the current UAC and the upcoming One.
Great job!
IOD slightly decreased by 0.04 points from previous update.
IOD: http://www.bom.gov.au/climate/enso/iod_1.txt
Huge TS 150kms east of chennai!!!
High chances for S.chennai upto pondy to get these rains if it doesn’t weaken.
North chennai
Nil
A big pink bulb nearing chennai coast..
OMG…UAC/related convection encircling Chennai?? Nice to see such a phenomenon after long time 🙂
http://www.weatheronline.co.uk/weather/satellite/Asia/India/Infraredcolor.htm
Good morning guyzz….have a nice day bloggers…
No have a raindy day to bloggers
Gud mng all, perfect start to June, cloudy and pleasant.
power of topic 🙂
today only starting. real cyclonic rains will be 3rd early morning.
U r always great ..we failed to understand your technical jargaon
PJ is first person to identify these rains though he lost little-bit confidence yesterday.
Great job roa sir
Exellent topic tdy:-)
Excellent topic Rsrao..
Excellent explanation.. Thanks.
A typical rao explanation .. hats off ..
Look at that
But I have doubt which direction ts moving
See RADAR animation it is moving SW
W/SW S.Chennai may get a hit.
Cool Mid to upper level clouds made into city… what a pleasant start to the month of june.
Did you bring this as your birthday gift to bloggers
Haha.
Which direction ts moving?
Check the winds from 3 to 6km height From updated 00utc charts
I’m waiting………
Steve it moving from NE direction. See the wind above 3 kms height
http://www.imd.gov.in/section/dwr/dynamic/doppler-vp2.htm
Is it from NE to SW PJ?
NE to SW
Slightly ENE I think dude
No the TS is moving in NE direction.
Check that image.
Moving away??
Rao, congrats for the great topic and 1st topic. I have not lost confidence. Rao. I am always for rains.
Yes PJ, whenever u are confident rains are on the cards.
This is not VS Rains…..!
Typical UAC rains guided by 500 HPa
Rains are on the way PJ….
not sure. Today sai.
Hmm…
Real game will be on 2nd and 3rd early morning 🙂
Hoping for the best rami
spot on.
The storms extending north is our chance.
http://www.imd.gov.in/section/dwr/dynamic/doppler-ppv.htm
I don’t think Central chennai will get a hit from this storm.
nope , Whole chennai will cover by the strom
Yea let’s hope the North one starts blooming.Depends on its intensity.Wish it doesn’t weaken. But high chances for S.chennai upto Cdl.
Yep . But storms Might flank towards north
Once it enters into chennai it should rain heavily …as the clouds already reached enough heights
UAC power Near TN. But very slow moving.
Nice to hear PJ
i said no rains, u are happy ah.
But sir north chennai will miss the rains:-(
even south chennai will miss if new storms dont extend north.
Areas from mahabalipuram to receive rain….north to it will remain dry with few drops of rain
PJ.. i feel this TS is for Chengalpet to Pondy areas… wats ur take on this?
See why the the entire mass wont enter Chennai. It will just go down based on this circulation.
http://earth.nullschool.net/#current/wind/isobaric/700hPa/orthographic=-280.28,13.69,2048
UAC distant effect PJ
yes rao.
As uac comes near us wind will come from east
Fireball nearing the coast:-P
This on 3rd June – Surely on June 3rd, the ball wont miss Chennai
http://earth.nullschool.net/#2015/06/03/0000Z/wind/isobaric/700hPa/orthographic=-280.28,13.69,2048
PJ So This Ts might miss Chennai ?? But Storms might flanks towards North
yes. but if we see circulation it has to go down and flank south. Lets hope i am wrong Paul
Pj Anna , New stroms Will develop??
i hope. It should be in north. Then only we have chance.
Anyway anna , We got a cool Morning
Sir we can expect some isolated rains today for city..Atleast after pm
Sorry to say sir… Let it be pj
Hmm rami
The June 2nd, 3rd rains should make many non UAC believers to take back seat – Mouli, Vela, Raijin. All doubt UAC rains.
Thats enough from the UAC:-P
Still game not over. more to come from 2nd BOB system
I know rao sir I think this june is one of the wettest month:-P
Yea exactly! Eagerly waiting for second 😀 😀
Chennai should at least get luck this time to make records
Hoping the rains will extend up to SAP and Interior Tn
we have rain today morning?
No chance
Aiyoo so many Kids expecting rains from the big ball. Atleast for them it should rains. Hope the TS takes own course and not the circulation. I dont have the heart to say it wont. The new storms poping north.
Really New storms Deveoping??
gud english 😛
http://www.imd.gov.in/section/dwr/dynamic/doppler-ppz.htm
Yes pj sir
The TS clearly follow the UAC!
Yes Sir , It might Move Towards Nagai
cool climate at Chennai..thanks for the UAC……….
But no rain:-P
will rain pa
K pa
Desperately wish Rao’s topic come true we are literally on verge of buying water after 9 months today
suerly we will get drizzles
That’s sure:-P
Hoping For that . Storms should Form North North East to get rain
i think so the storms have flanked north
New storms developing
yes
Hope More storms will develop
SWM onset over Kerala anytime from now within 48 hours time, winds turned SW over south kerala coast and humidity increased above 75%. Let wait for short time for the onset over Kerala.
Wow…MJO nearing amplitude 2, great supportive sign for the present & upcoming systems. http://www.bom.gov.au/climate/mjo/
Exellent roa ji the mjo attain phase 2 any chance this UAC intensified in to a lpa;-)
It’s amplitude 2 and phase 1. But this UAC descending to 850 Hpa level on 3rd morning, so nothing but LPA right over chennai. So rainfall intensity will be more on tomorrow late night/3rd early morning.
What abt Chennai weather guyzz…is it overcast or sunny there
overcast
Nice
Very chill and pleasent tdy:-P
Tiny Popup Seen over East of Chennai In 50kms
yes..it might go to chengalpet?
Depends on how far its flanks south.
For Chennai, the TS has to come from NE/ NNE.
Yep , I already said In below Comments
Congrats Raoji, perfect timing to pen your first topic,

Image of Skytree in Tokyo during 8.5 earthquake on May 30 2015. It’s just 20 minutes walk from my apartment where I stayed
8.5? o.O
They said 7.5 I guess..
As per JMA it’s 8.5
Radar not updating.
yes, stuck at 3:10 GMT for me…
Rami,
MJO emerging into Phase 1 closer to Phase 2, hence we can expect MJO by 03rd over Phase 2, the upper level winds too indicate the same, as i was watching for the past 4 days, the upper level winds velocity is increasing and becoming more active nowadays.
Depending on above conditions, SWM onset over Kerala likely in next 48 to 72 hours time.
Partha, But where is MJO related convection? Actually when MJO amplitude increases greater than 1, then it will exhibit in convection form. But I could not able to trace out. Can you locate it for me?
massive dark clouds
Bangalore City -24.2mm , hal airport-32.3mm, hal ap finally manages to beat city ,yuktix aws in hebbal has got 71mm!!
small spot very close
Seems like even Andhra is enjoying rains 😀
That all the Blue ones are fake.
See the time and date its old
No hvy rash of storms in machili rada r real
Yeah, i saw the old one.
No it’s not fake.
Its real only.
Yes rain band coming from Telangana towards SAp only to merge with chennai convection by today evening . So big game will unfold from tomorrow morning.
