Dry Weather conditions that has been the pattern for the last couple of days over most parts of Tamil Nadu is set to continue for the next couple of days or so as Bay awaits the development of the next synoptic activity to bring back rainfall activity across most parts of South India. Over the last week or so the rainfall activity has been pretty much confined to parts of Andhra Pradesh, Telengana and a few pockets of Coastal Tamil Nadu as the rainfall anomaly chart indicates.
The Low Pressure area currently persisting in East India over parts of Jharkhand and Gangetic West Bengal is expected to slowly loose its influence in the days to come as it moves in a more NW direction over the Gangetic Plains and towards NW India. In the meanwhile there is a developing Upper Air Cyclonic Circulation that is expected to become a Low Pressure Area around the weekend or early part of next week which could possibly bring back the synoptic support which is needed for rainfall to revive over Peninsular India
With clearer skies and pretty much poor upper level moisture in the atmosphere the temperature has gone up a couple of notches over most parts of Tamil Nadu. The day time maximum temperature is expected to stay about 2 / 3 degrees above normal for the next few days until possibly 11th / 12th of September post which we could see some respite from high temperatures.
While mostly dry conditions are expected to prevail over vast swathes of Tamil Nadu there is a possibility of some stray thunderstorms that could possibly form in the coastal stretch between Mahabalipuram and Pondicherry to provide some passing showers in a few areas.
Chennai is expected to see a day time max temperature of around 35 / 36 degrees with slightly humid conditions during the evening with the advent of weak sea breeze around 4 PM.
