After putting up with days of scorching heat, the city got a brief respite on Wednesday with cloudy weather prevailing in most parts, some even receiving light showers. This breather, however, is expected to last only till Thursday.
Officials of the Indian Meteorological Department (IMD) said the sudden change in temperature was due to the formation of troughs of low pressure over both the Arabian Sea and Bay of Bengal. “There are troughs of low pressure over the Bay of Bengal towards coastal Sri Lanka, Tamil Nadu and Andhra Pradesh, and over the south-east of Arabian Sea off Karnataka and Kerala. That is why Tamil Nadu has received good rain,” the IMD official said.
But the State cannot expect heavy rain as these are only troughs of low pressure, which means there is only 50 per cent chance of rain, the official explained. The cloudy weather too is only a brief phenomenon as only 20 per cent of the cloud mass is left, which is moving towards the Lakshadweep islands.
On Wednesday, the maximum temperature was 32.7 degrees Celsius while the minimum was 21 degrees Celsius.
