Dry Weather to Persist over Tamil Nadu

The ongoing dry spell in Tamil Nadu for the last fortnight or so is expected to persist with no major rainfall inducing synoptic conditions over the next few days.  Except for the one spell of rains which was fairly widespread over the Delta region before Pongal it has been pretty much dry weather since the turn of the new year.

Despite January carrying a low average it is ironical we are seeing a below par start to the year with a deficit of about 61% for the Tamil Nadu & Puducherry sub division.  Numerical Models do not expect any major improvements to the rainfall status until end of January possibly.

While there exists a Trough of Low over Southeast Bay it is likely to drift in a W/SW direction towards Sri Lanka in the days to come.  Numerical Models do not expect any major influence to Coastal Tamil Nadu from this Trough of Low  with possibly Sri Lanka enjoying better rainfall prospects.  While parts of South Coastal TN could benefit from stray showers nothing worthwhile is expected overall.

Under the influence of the Western Disturbance prevailing over the Indian Sub Continent for the next couple of days the overall temperatures will stay closer to normal or slightly above normal before another spell of Cool conditions hits Tamil Nadu towards the month end.
