Getting warm & humid

Recent satellite images showed lot of cloud activity over southern bay and near 5th parallel. Even South-south-tamilnadu had some share of scattered mild showers.
Chennai:
we are experiencing near 30 deg temperatures and bit more humid than previous weeks.
Certainly for the past 4 days the minimum temperature was not at all low.
Today, morning it was fully cloudy and warm.
Now(29-Jan-09, 11:35AM) the humidity is on the higher side 65% and temperature is rising steady at 28.8°C.

Are we nearing the end of winter season or something else..??
We might have a localized shower or two in next 72 hrs.
GFS models suggest nothing and will remain so.
MJO forecast suggests still we are in a mild wet phase... and will continue till 10-Feb-09.
Here is the long range precipitation forecast till June-2009.... It suggests a more than normal rainfall for Western Peninsular India.

Valcanoe - "Chaiten" .... Fuming Anger!


A classic shot of 2 cyclones

A classic shot of 2 cyclones
one to north-east of Madagaskar "TC - ERIC"
and other one approaching Madagaskar from South-west "TC - FANELE"

Mild winter day & night

We(Chennai) are experiencing a mild winter day & night from 10-Jan-09 to till date.
From 15-Jan-09 to 21-Jan-09 there was some cloud activity over the South-south-bay near the 5th parallel...gradually it became a huge cloud mass and moved south instead of moving north-west.
Now it's a potential cyclone just south of Equator.
Again the Bay is clear and there are some cloud formations over South-western Arabian sea.
Going thru all parameters, next 5 days will be with bit warm days and mild nights.
The low temperature will be around 21 deg.

A sudden change in MJO forecast says,
that we are currently in a wet phase and will continue till 7-Feb-09.
Previously it was predicting a wet phase from 2-Feb-09 to 14-Feb-09.

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.
