As we wait for Northeast Monsoon to show signs of revival and build up some bit of momentum in what is a very crucial period of the season coastal areas have been getting isolated light spells for the last couple of nights. Yesterday once again few areas of Chennai recorded light rains during late evening and early morning today.
Looking at the satellite images it appears parts of North Tamil Nadu and South AP could see spells of moderate rains in the morning hours. Some of the remnant moisture when it crosses the coast under the influence of convective process triggered by rising air particles from the ground through day time heating will develop into thunderstorms in the interior places of Tiruvallur / Vellore / Kanchipuram & Tiruvannamalai giving sharp spell of showers before afternoon.
With Easterly winds much better compared to the past few days its only a matter of time for the first good spell of rains to hit the coastal areas of Tamil Nadu. Going by weather models it appears North TN and South AP could benefit from this first spell of reviving Northeast Monsoon 2019.
There is a chance for one or two places around Chennai and suburbs to receive a heavy spell of rains later in the evening while most parts of the city could see on and off spells of rains today with moderate rains at times.
