Near Heat Wave Conditions to Prevail over North Tamil Nadu

While most of us were expecting the Heat to notch up a gear or two, yesterday the Summer heat over Tamil Nadu not just notched a couple of gears but went onto Overdrive as North Tamil Nadu & adjoining parts of Rayalaseema region sizzled under the relentless afternoon sun.  In a day which started almost a degree higher than the previous day by 9 in the morning saw Westerlies dominate right through leaving no chance for the moist sea breeze to give any respite.

Tiruttani recorded a very high 44.5 while coastal areas in North TN like Chennai, Cuddalore, Pondicherry recorded 3 degrees higher day time temperatures compared to Sunday and in most cases 5 / 6 degrees higher than Saturday highs. Both Chennai observatories recorded their hottest day since May 2015 when Nungambakkam recorded 41.1 and Meenambakkam recorded 42.4 during the third week of the month.

Going by numerical models there is unlikely to be any immediate respite as the day time conditions are likely to be oppressive and near heat wave conditions are likely to prevail over most parts of North Tamil Nadu, Coastal Andhra Pradesh under the strengthening Westerlies.  Models indicate many places in Vellore, Tiruvallur, Kanchipuram, Tiruvannamalai and parts of Villupuram districts to see day time temperatures peak around 42°C.

As one can see from the temperature anomaly chart it would be an understatement to say oppressive afternoon conditions are likely to prevail as large swathes of North Tamil Nadu is likely to see day time temperatures to be around 4 / 5°C above normal.  Most of Tamil Nadu sees average maximum temperatures of less than 40 for this time of the year and according to IMD’s parameter of 5 to 6 degrees above normal is heat wave condition hence theoretically we might see lesser places fall under the Heat Wave definition.

Nevertheless it would make a lot of sense to take adequate precautions as the current prevailing conditions are bordering on heat wave.  Chennai is likely to see similar conditions as yesterday with models indicating Easterly sea breeze expected to make a difference after 12 PM though the maximum temperatures could be a shade lower than yesterday but overall the heat quotient will be high and avoid day time travel especially if you are using a Two Wheeler.

          Yes

          Models estimated today till Thursday to be around 3 / 4 degrees above normal while Friday and Saturday or is estimating 5 degrees above normal

          • Srinivas

            When you say Normal, is it an average for the month?

          • Ramirao

            models output ought to change 🙂

  • Vigneshwar Narayanan

    @pypkmsrikanth:disqus
    Are lack of tress making the urban heat more pronounced

    • SrikanthK

      Possible reason no doubts about that

    • Srinivas

      With more and more high raise buildings and close to each other, we have created for ourselves a zone similar to being close to mountains, where radiation continues to happen long after sunset.

        • Ramirao

          only for west of Chennai?

          • SrikanthK

            Even west of Chennai max is showing 43 but is showing a reduction in temperature by 14:30 which is possibly influenced by cloud cover

    At least a rainy day possible in next 3 days for Uthiramerur.

    • SrikanthK

      Tomorrow looks a fair chance if winds work out well

      • Ramirao

        Any news on SWM? Delay or normal?

        • SrikanthK

          Let’s see everyone betting on normal onset so it must be normal or early then

  • Ramirao

    IMD:
    The southwest monsoon onset over Kerala in this year is likely to be close to the normal date. It is likely to set over Kerala on 30th May with a model error of ± 4 days.

    ♦ The southwest monsoon has further advanced into some parts of southwest Bay of Bengal, some more parts of southeast Bay of Bengal and north Andaman Sea and remaining parts of Andaman & Nicobar Islands. The Northern Limit of Monsoon (NLM) passes through Lat.5.0°/Long. 80.0° E, Lat. 7.0° N/Long. 85.0° E, Lat. 10.0 °N/ Long. 90.0° E, Maya Bandar and Lat. 16.0° N/ Long.98.0° E.

    ♦ Conditions are favorable for further advance of southwest monsoon into some more parts of southeast Bay of Bengal, some parts of east-central Bay of Bengal and remaining parts of north Andaman Sea during next 48 hours.

  • govind raj Adam

    any chance of rain at least next week since we need badly ?

    • SrikanthK

      Sir some light rains are forecasted by few models but I would not put my money on them Sir the Westerlies are too strong and if the Low evolves little more in Bay then they will further strengthen

      • Venkit PS

        Today is a benchmark of heat in Chennai. We stay pretty close to the coast and by this time normally it will be a pretty pleasant weather, but today, first time this summer the water dispensed in bathrooms are still coming out hot like 38 to 40 degree Celsius. Hope I don’t have to describe the out side conditions.

        • SrikanthK

          Sir we are just seeing the start with bad days ahead

      Good Morning. 23 now in B’lore. Any idea when will be the next closest chance for some relief rains in Chennai? I remember someone mentioned it as End of May.

      • narayanan_ky

        Chennai will get relief with SWM onset with thunderstorms by may end as winds will turn south Westerly now it is dry North Westerly….June will also be quite warm but rains will happen…July gets more cloudier

      • narayanan_ky

        For Bangalore hot days are over it will stay cloudy and pleasant during SWM with occasional rain…it gets more rain during premonsoon time

          Absolutely once Westerlies kick in its going to be heaven in Bangalore especially with Monsoon current active
