This Kathiri Veyil period has pretty much gone without heat wave impacting Chennai & most parts of Madras so far. Things are expected to be pretty much similar today as well with temperatures expected to stay lower across the state under the influence of the evolving disturbance in Bay.
The Wind Discontinuity continues to exist over the interiors of Peninsular India which is likely to provide rains over the interiors of South India. With a Upper Air Cyclonic Circulation existing off Sri Lanka we are likely to see strong Easterlies move into the Peninsular India. This is likely to trigger spells of heavy rains over parts of Kerala, South Interior Karnataka. In Tamil Nadu we could see a few places along the Western Ghats get spells of heavy rains later in the day. Coastal Areas could see cloudy conditions in the early part of the day with few stray showers possible.
Under the influence of the evolving Bay disturbance today also will be a Kathiri Veyil day without much of Veyil as heat takes a backseat bringing much respite to places in South Tamil Nadu. Most parts of South Tamil Nadu is likely to see cloudy conditions keeping the temperature under check. Day time max in one or two places in North Interior Tamil Nadu is likely to be around 38 degrees. Most other places will possibly see day time max conditions of around 35 / 36 degrees.
Chennai will see a day time high of around 35 / 36 degrees with partly cloudy conditions during the early part of the day. Humidity is expected to be fairly high which could make the real feel show up.
