An new embedded Low in the axis is likely to form in Central India by around 3rd/4th August.

As the erstwhile system in Rajasthan merges with the Monsoon axis, the Western end of the axis rapidly moves Northwards. Due to BB-3, the slope Eastwards of the axis is steep, sloping SE.

Friday 31st and Saturday 1st August..Heavy showers are likely in Kashmir, H.P. and Uttarakhand, Western U.P. and in Western Nepal. 

Rains increasing in both Punjabs on 1st August and continue on Sunday 2nd. 
(Gujrat in Pak Punjab gets increasing precipitation from Saturday. Saturday and Sunday showers will measure around 20 mms per day).

Heavy showers in Chattisgarh. Jharkhand and West Bengal.

Night rain in Chennai

Today's [23/7/2015:: 2145 hrs IST] rainfall at Chennai played a decisive role.  Thunder clouds developed in NW of Chennai by 1600 hrs and rain was realised in North Chennai.  Later in the evening by 2000 hrs IST clouds developed in southern sub urb and moved in North / NEly direction to give rain with Thunder storm in the southern parts of the city. The winds were from Southerly to SWly direction

again cloud concentration below 13 Deg latitude.
As the SWM wind strength is diminishing light to moderate rain will be experienced in Kerala and TN.

However NCR region ,Haryana, East Rajastan & Parts of MP & Maharastra is to witness moderate to heavy rains.

Ariyalur Rain

The very heavy rain above 10 Deg parallel i.e along Ariyalur (158.0mm) [11.13 Deg N], Senthuri (51.0 mm) [11.2 Deg N] Aduthurai, Kudavasal etc was mainly due to the dense clouds developed by 15Z [2030 hrs IST]. That is evident from this picture.

Similarly the cloud mass lingering over central India {MP, West UP, Rajastan, Gujarat} gave copious rainfall.

The upper wind map of to day shows diminished strength of SWM.  even though that is the nature, it may give rainfall to west coast and TN again along and off 10-11 Deg parallel.

 The 700 hPa wind also indicates this.

 The gradual (past 24 hrs since 06Z of today) decrease in strength of SWM winds in the west, especially in the deep south and then slight increase of strength of SWM winds today [21.07.2015/ 09Z] is indication of LESSER amount of RF in Kerala & Karnataka region which is UNCOMMON for July. 

"ADI PERUKU" is a festival usually celebrated in the upstream and down stream Cauvery districts of Tamilnadu [i.e Dharmapuri, Krishnagiri, Salem, Erode, Namakkal, Karur, Tricy,Thanjavur, Tiruvarur, & Nagapattinam districts of Tamilnadu and Karaikal district of Puducherry] on 18th day of ADI month i.e THIRD AUGUST.  I hope rain guard will be cordial for Tamil Nadu.
