This mid,upper-level circulation is now tracked as 94B.
There's no low-level circulation associated with this system.

At low-levels, a LWD is seen from N-central India (N Madhyapradesh) to S-coast Andhra ... http://ow.ly/i/b66N6
Present W Bay circulation 94B is expected to Slowly drift W-N-W into N Andhra coast on 4-Jun and continue west .. http://ow.ly/i/b66QP
On, 6-Jun, the Bay circulation is expected to drift into Arabian sea along central coast Karnataka and intensify.. http://ow.ly/i/b66Vs

On 5-Jun, evening, the Monsoon is expected to launch into S,central Kerala coast !
At present a low,mid-level circulation also seen over S Arabian sea and this is activating the cross-equatorial wind and the Somali jet !

HEAVY T showers expected along S,central,N-E coast of Andhra ... http://ow.ly/i/b68td 
More HEAVY T showers for S,S-central,S-E,S-W Karnataka and Bangalore on today and 3-Jun.

WD update
~~~~~~~~~~~~~~

Due to WD trough...
Scattered T showers for Kashmir, Himachal, S,S-W,central,E Rajasthan.
One or two over Punjab, Haryana and W Uttarpradesh

WEAK PRESENCE OF SWM

The SWM winds have penetrated upto 100 Deg East IN LOWER LATITUDES.  That to the vertical depth of westerly is APPROXIMATELY up to one km amsl.  This weak westerlies make cycir-upper air circulation-[just like monsoon depression] and as a result (of Yesterday's cycir) it was cloudy over North Chennai [of course with light rain] and south CAP un to Machilipattinam.  This will further move northerly and give lesser rain.

Even the 200 hPa wind is weak NEly.  The 100 hPa wind at Chennai [i.e 13 Deg N] is also Easterly with strength 36knots. The SWM penetration aloft [~1.5km amsl] is producing weather in Bay and SE Indian coast.

Similarly the weak UAC in AS may pull SWly winds to AS.

NE monsoon style rain for Chennai on 1-Jun - odd !


8:40am, Its very rare to see Chennai RADAR on 1-Jun showing "Rain approaching city from N-E like NE monsoon" ... http://ow.ly/i/b4ITR
This is due to the S-central Bay mid,upper-level circulation.. which was moving West for past 3 days.
At present the mid,upper-level circulation over Bay is near N,central coast Tamilnadu and S coast Andhra ... http://ow.ly/i/b4J2A

Due to this circulation a HEAVY T shower line is seen pushing towards N Tamilnadu coast for past 4 hrs... http://ow.ly/i/b4J8w
9:30am, #Chennai - slowly getting ready for a T shower. And reports of rain from Triplicane zone.

At present a mid,upper-level WD trough is over N,N-W India and drifting East.. this can drift the present Bay circulation to N and then N-E
During next 24hrs, the WD trough is expected to deepen to 20N along N-W India and Pakistan ... http://ow.ly/i/b4Jvj

GFS suggests a Westerly movement for present Bay circulation .. meaning it'll cross N TN coast and push to Arabian sea on 4-Jun !
If this happens, the Monsoon onset over Kerala will be delayed till 5-Jun, but HEAVY rain ahead for S peninsula ... http://ow.ly/i/b4JDH
