Yesterday saw Isolated Rains in Tamil Nadu particularly around the Western Tamil Nadu region with Ooty recording 42 mm rains till early morning. Similarly places like Hosur, Manapparai, Yelagiri, Bodi etc also saw rains as interior places of Tamil Nadu benefited from the Line of Wind Discontinuity providing relief from the heat. Few places around Coimbatore also got some afternoon showers yesterday bringing down the temperatures in the region.
Today also we are likely to see similar conditions with many parts South India expected to receive these spells of rains aided by the Wind instability. Last night parts of Hyderabad received heavy showers with the IMD AWS in Golconda near the Telengana capital recording 52 mm rains will morning. Today also conditions are ripe for another set of midnight thunderstorms in the Telengana region along with parts of interior Karnataka and Rayalaseema region.
Rains in Tamil Nadu are likely to continue with places around Coimbatore and along the Western Ghats expected to get some rains with one or two places in the Nilgiris / Valparai region getting fairly heavy spells of rains.
Temperatures are expected to remain lower keeping with the pattern of yesterday with most places recording a degree or two lesser bringing some marginal relief from the heat across South India. Thanks to these developing thunderstorms West Interior Tamil Nadu is likely to see some much lesser temperature compared to the season so far which is a welcome news for people in the region who has been pretty much seeing oppressive heat since March 2016.
Chennai is likely to see the Easterly Sea Breeze moderating the day time temperatures once again today with more Southerlies & South Easterlies dominating the early part of the day. There is some chance of isolated rains around Vellore which could bring a huge relief to the Heat Capital of Tamil Nadu.
