Almost an Electric shower

As expected we(Chennai) almost had an electric shower...
We had a sharp shower late into night with any electric activity.
From yesterday morning, it was DIM with a mild high cloud cover, Temperatures nearing 30 deg, Bit high in humidity around 60% and in late afternoon lot's of low cloud formations were seen.
We even had some sprinkles of rain around 6 PM.
After that also clouds formations were moderate and after midnight we had a shower.
Satellite pic analysis and latest visible satellite pic shows some formations overnight and nothing much now(16-Jan-09, 12:30PM).
For the past 3 days we have some moisture from sea, that is creating these local bursts.
Please note: These local moisture based activities CANNOT be predicted using any GFS models till date. These can be predicted ONLY using VERY LOCAL weather data.

Today(16-Jan-09), it's like a perfect November monsoon day.... bit warm and sultry.
Less cloud formations can be seen.
Forecast: These local disturbance will continue for another 48 hrs, then gradually the night will become cold again and with DEWs in morning.

Surprise Day in January!

What a surprise we woke up with slight drizzle.
No DEW around.
Temperature was mild with some slight breeze blowing from NORTH.
In the morning it was partly cloudy and with some signs of MORE drizzle.
Today thru the day we recorded high humidity..at 91%
Now (4:43PM) it's drizzling mild and steady.
More drizzles and even a mild shower is forecast for late evening. And from tomorrow morning this weather pattern will slowly move away.
Going by the latest Visible & IR satellite image...

We can see some mild cloud cover can be seen over most of North-Tamilnadu and South-Andhra.
This is causing some local formations and that too weak in nature.
We can expect this weather pattern for next 24 hrs and melt away.
Latest numeric models suggest... more rain for Southern Tamilnadu.
