Despite the possibility of rainfall in southern parts of the State, most of north Tamil Nadu will continue to experience searing heat. The mercury level, however, could dip slightly after Sunday.

The Regional Meteorological Centre, Chennai, has said that the weather models indicated a tendency of a marginal drop in the maximum temperature over Tamil Nadu for three days from Sunday. Enhanced rainfall activity, particularly over south Tamil Nadu and districts along the Western Ghats, would help control the day temperature from peaking further.

While the maximum temperature is predicted to rise 2-3 degrees Celsius above normal in few places across the State on Saturday, the number of locations that would experience above average temperature in the day [by three degrees Celsius] may reduce to one or two between April 27 and April 29.

Officials of the RMC said that a change in wind pattern from southerly, westerly to easterly winds would help moderate the day temperature in parts of Tamil Nadu. P. Senthamarai Kannan, Director, Area Cyclone Warning Centre, RMC, said a weather system was likely to enhance rainfall of light to moderate intensity in south Tamil Nadu and the Western Ghats districts. This may have an effect on the daily temperature too in the northern parts.

However, it would only have a marginal effect on the maximum temperature. For instance, the day temperature in Vellore is predicted to hover around 40 degrees Celsius on Saturday. It may drop to 39 degrees Celsius on Sunday. Moisture incursion, owing to the weather system, may prevent mercury level from rising further, he added.

On Friday, Madurai and Karur Paramathi sizzled at 40.5 degrees Celsius. Chennai’s Nungambakkam and Meenambakkam too recorded an above average temperature of 35.8 degrees Celsius and 37.3 degrees Celsius. A few places in Coimbatore district and Thoothukudi received mild rainfall till Friday evening.

The RMC has warned that high maximum temperature, high humidity and above average night temperature may cause uncomfortable weather at a few pockets in Tamil Nadu on Saturday.
