However, Met officials are uncertain if the phenomenon will continue to yield more rain for TN.
Heavy showers on Wednesday took residents of Chennai and a few nearby pockets by surprise.
The rain, however, helped in bringing some respite from the scorching heat that has begun soaring during afternoons.
The whole of Wednesday was overcast and residents were hoping for good showers.
By afternoon, while some parts of the city received just mild showers, other parts had heavy showers greeting them. Nungambakkam recorded 31.5 degree celsius, one degree below the average, and Meenambakkam registered normal temperature of 32.4 degree celsius.
While the temperature has been unusually high over the past few weeks, the climate was relatively cool due to showers in other parts of the state on Tuesday. Regional Meteorological Director in Chennai S.R. Ramanan said, “These troughs tend to move in a westerly direction.”
But we will have to wait and watch. The only thing for sure is that parts of Tamilnadu will see rain in the days to come, he added.
