The last of the rain clouds are likely to fizzle out over the next couple of days and mercury levels will climb up as summer nears its peak in Tamil Nadu. The latest weather bulletin issued by the Regional Meteorological Centre (RMC) on April 18 warns that the maximum temperature is likely to go up by 2 to 3 degree Celsius at isolated places over parts of northern, western and coastal Tamil Nadu in the next few days.
