  4. Looks like yesterday inside 50km radius 500hpa played a role with TS which was from SW to NE which could be the reason for the storms to tilt towards NE. Infact all the Storms weakened while tilting towards NE and some overhead popups triggered by Intense Thunderstorm resulted in Some Showers over the City

  6. Good Morning All,

    Today is the day which completes 3 years since I joined KEA Weather. This 3 years thought me lot of learning about weather across the globe. Today I feel that i have made a right decision to join this blog, this gives lots of happiness and satisfaction. I still remember the first person to talk with was Selvan, he has thought me lot of things in which laid the platform for me to grow further. Thanks Selvan. People i have been interacting the most is Thala Shiva. He is always an enthusiast. He gives lots of energy to others, he has supported me in several ways. Thanks Shiva. Then GTS, he has been my latest teacher about weather, he has given me lots of inputs on how to read some charts etc, Thanks GTS. Then Ehsan, he is a leader by example, given lots of freedom and also supported me in many ways, he too laid platform to all of us in learning about weather, Thanks Ehsan. The Mr Shankar, he has helped me in many ways to grow in this blog, I cannot just say Thanks, he is wonderful friend and good administrator, we had spent more time in discussing about this blog and weather.

    Thanks to other bloggers also, who has shown patience in listening to my comments and making it valuable. It is really giving me lots of joy when i realise that i have completed 3 years. Lets take this blog to new highs and enjoy ourselves with our presence here without any disputes.

  7. Good morning..South and western Chennai suburban recorded more than 40-50mm rain while the most parts of city had average 20 to 30mm rain over night.

    Forecast:

    Some parts of Chennai city may have light rain for couple of days due to convection and few heavy spells are expected in weekend.

    North Western Interior Tamilnadu districts including Erode ,Salem Namakkal and Dharmapuri will have medium to rather heavy rainfall from coming Wednesday to Saturday.

  8. our PJ and ehsan should be happiest people on this day. PJ must be happy, because he predicted yesterday’s rains accurately and ehsan for seeing some rains since he also wanted rains.

  9. Congratulations Rao ji and PJ sir for perfect prediction of rains yesterday. Rao-Ji ,your prediction based on VAMCO mihght not fail today. There is a good possibility of rain today also.

  10. This year too, the south-west monsoon is likely to spill over to October after a delay in its withdrawal, beyond the normal date of September 30. This is a trend that has persisted for the last few years. This makes it likely that the arrival of the north-east monsoon could get delayed over the southern peninsula.
    According to the extended range weather forecast by the India Met Department, India Institute of Tropical Meteorology and the Hyderabad centre of the India Council of Agricultural Research, rainfall is likely to improve over southern peninsula and parts of central India during the next 10 days.
    Moderate to heavy rainfall is expected over certain parts of Maharashtra, the west coast, and the east coast till the end of this month.

  11. The quantum of average monsoon across the country during June 1-September 20 has been 718 mm which is 14% less than the LPA of 839 mm.

  12. contrary to expectations, rains were not all that heavy. heavy spells concentrated tiruvalloor-kanchi pockets only. this is not usual september rains. any way something is better than nothing. few more 5 centimters are required in another 10 days.

    ss

  13. so swm is done for the year(hope there is no more late surge expected as w.pacific hosting a typhoon in coming days)..considering the aspect of monsoon covering all over india on jun 25th and monsoon withdrawal commencement over nw on sep 4th , july 10th was the most active day and jul 2nd was the least active day of this season wrt all india rainfall.. Attached the sat images of two contrasting days

  14. I was in Cheyyar from Thursday to Sunday. On friday and saturday there was just few drizzles, missed heavy rain on Saturday. Yesterday afternoon i left Cheyyar and reached Chennai by 17.30. They got good rainfall yesterday night, what a pitty…

  18. Thanks one and all for your hearty wishes!!
    One more special event today which no one mentioned yet. Today is the day, the sun start its downward journey crossing equator! (Dakshinayanam)

  19. The ITCZ maximum northerly location is at the Indian-subcontinent and adjoining China.. This is because of the intense heating of the land mass, much more in intensity and spread than other lands at this latitude.

  21. Oh!! GFS expects LPA to still cross TN, however it is embedded in a trough with a stronger vortex on the eastern side crossing moving NW to cross Orissa/AP

  22. Last year, ECMWF was the first model to pick and perfect Hudhud, infact GFS didn’t even pick it till 1 week before!!

    (Incase you are wondering, I’m posting negative statements about GFS because of the current run.)

  23. The drastic change in GFS run is because of a dire change in the forecast for wind shear. Compare 18Z wind shear with 00Z(latest) run shear. Especially EC BOB
