Why showers failed Chennai

CHENNAI: The city has been experiencing cloudy skies during the day and thunderstorms in the evening, but the rain that was forecast never arrived. Instead, the weather was hot, stuffy and sweaty.
This is due to the convergence of opposing winds from the east and the west or the trough falling over the interior parts of the state. This brought intermittent showers to the suburban parts of the city while those close to the coast remained dry and sultry due to the incoming easterlies that travelled towards the convergence area over the interior region.
Weathermen have forecast thunderstorms and rainfall in the city and suburbs for the next two days. However, private forecasters and bloggers said rain may continue to skip the city and move to interior areas.
IMD said a cyclonic circulation lies over south Tamil Nadu and neighbourhood areas extending up to 0.9km above mean sea level. "A trough/wind discontinuity runs from the cyclonic circulation over central Madhya Pradesh to the cyclonic circulation over south interior Tamil Nadu and neighbourhood across interior Maharashtra and interior Karnataka at 0.9km above mean sea level," an IMD official said.
On Monday, a cloudy weather maintained the day temperatures at 35.7 deg C and 36.2 deg C in Nungambakkam and Meenambakkam which were near normal for the month. On Sunday evening, there was thunder in some parts of the city, but the rainfall was restricted to neighbouring and interior districts.
Mahesh Palawat, chief meteorologist, Skymet Weather said the trough is influencing the rainfall in the state and it may continue to bring rain at least for the next two to three days before its intensity begins to drop. Blogger Pradeep John said the city also missed its share of rain on early Monday morning as the storms moved away from the city.
