I was away with work for the past 15 days.
Now back on time.
For the past 2 weeks, chennai experienced low temperatures & dry weather.
Low of the month was : 20.2°C (4/3/08)
Take a look the past 5 day Temperature & Wind direction.
You can look at the gradual increase in temperature.
The wind direction is also good, favoring a shower..!
From today morning, there's a lot of cloud cover.
There's a 100% chance of small showers in the coming days.
This may be the shower that brings the all expected SUMMER to Chennai.
