We have UAC in the lower to mid levels 700 hpa (3.1 kms) from surface, located north east of Chennai, it brings perfect convergence zone for North TN. Morning itself we are seeing ideal conditions with dark clouds lurking around.
As day goes on with more heating things will become much better for rains in North TN which includes KTCC (Kanchepuram, Tiruvallur and Chennai & Chengalpet). The other districts such as Tiruvannamalai, Vellore, Pondy, Villupuram, Tirupattur, Krishnagiri, Salem and Dharampuri will also be in line of rains.
