Another day of sizzling heat ahead over most of TN

Weather Update

As expected by models yesterday saw the heat quotient jump across Tamil Nadu with many places recording their hottest day of 2019 so far. Tiruttani became the first station in the state to touch 40 degree Celsius for the year 2019 as Vellore, Salem, Karur & Madurai AP also recorded temperatures above 39 degrees. Both Nungambakkam & Meenambakkam at 35 & 36.8 recorded their hottest days of the year so far comfortably.

Today we could see more places inch closer to 40 degrees or possibly cross it as well as large swathes of the state, in particular over North TN and adjoining parts of Rayalaseema region are likely to see day time temperatures stay 4 to 6 degrees above normal making it extremely uncomfortable during the afternoon.

Except for a narrow coastal band along the stretch between Pulicat & Delta along with coastal areas of South TN from Ramanathapuram to Kanyakumari district almost all of the state is likely to see temperatures in excess of 36 degrees with many places likely to cross 100°F . Tomorrow could be similar story as models indicate abnormally hot conditions to continue for at least another day.

Wind Patterns once again are going to play a crucial role in the heat spell today & tomorrow. A large swathe of the state will possibly see poor surface winds which will increase Ground radiation in those areas thereby increasing ground radiation drastically. This will create occupational hazard to those who might occupy stationary positions during the afternoons.

Coastal areas like Chennai will possibly see Southwesterlies that would prevent sea breeze penetration thereby increasing the heat and giving a privy to the summer ahead once Westerly regime shift happens.
