From past few days, South Tamil Nadu has been witnessing few spells of rain, while northern districts at the similar time frame have been observing dry spell.
During the last 24 hours, isolated light rain and thundershowers were observed over southern parts of Tamil Nadu.
In span of 24 hours from 08:30 am on Friday, Nagapattinam witnessed 0.1 mm of rainfall and some traces of rain were also observed in Karaikal. However, the capital city, Chennai remained dry.
These isolated showers can be attributed to the combined effect of an off shore trough over Kerala and another trough which is extending from South Andaman Sea up to Southwest Bay of Bengal.
As per Skymet Weather, dry weather is expected to prevail over the entire state. Though rain activity is expected along the trough; but it will not have any impact over the mainland of Tamil Nadu. The state will continue to witness dry and humid weather.
At present, minimum temperatures are settling below normal by 2 to 3 degrees at many places over the state. While day maximums are settling near normal levels.
Weathermen expects marginal rise in both day and night temperatures over the region after 24 to 48 hours, resulting in hot and sultry weather conditions.
