As a precursor to summer day time temperatures in Tamil Nadu has been slowly inching up for the past few days. Yesterday Madurai, Salem & Tiruttani crossed 36 degrees as Chennai AP crossed 34 for the first time this year. The 36.6°C recorded by Tiruttani is the highest for the year among IMD observatories in Tamil Nadu.
Numerical Models indicate hot and dry conditions to prevail over the state with possibly temperatures notching up a degree or two for the weekend. Almost all the models are consistent on large parts of the state particularly in the interior places seeing above normal day time temperatures.
West Coast will continue to see temperatures stay 2 / 3 degrees above normal for the next couple of days before some marginal respite is seen. With clear skies dominating most of the Peninsular Landscape the days will be hot and uncomfortable across the region.
Models indicate the coastal areas of Tamil Nadu, up to 50 kms from the coastline, possibly getting moderated by the Easterly Sea Breeze while slightly further interior areas are likely to see fairly hot conditions during Mid Day.
