South West Monsoon Withdraws further, and may stall for next 3 days now...

Anti Cyclone in the Upper Air at 850 mb level, seen here along with the Monsoon Withdrawal Line...

and the LWD seen, keeping the Western coast and coastline "active" with Thunder showers.



Monsoon out of Delhi NCR and NW India...
But, wind pattern and 200 level jet streams indicate Monsoon still present in Coastal Saurashtra  and Maharashtra

Which means Monsoon winds still prevail in Mumbai..
Day temperatures will ease to 33/34c, and lower in Mumbai from Wednesday, 1st October, as East winds turn Northerly, and LWD becomes effective. An UAC forms off Mumbai , for a day or two, on or around 2nd October..
Mumbai can get the much awaited thunder shower 'any evening" ...its overdue since 2 days..though we see thunder showers every evening last few days in South Konkan and Goa, and along coastal Karnataka...

An afternoon Thunder shower likely in parts of Kolkata next few days...and Delhi NCR, warm with clear skies. 


Mumbai the Hottest in Maharashtra on 29th September....Mumbai Santacruz records its highest ever, hottest ever, September day today 29th , recording 37.0c !!. Previous record was 36.4c on 23rd September in 1972.
Colaba was 34.8c and Vagaries 34.5c today...Colaba IMD record stands at 35.6c on 24th September 1987 and 29th in 2010..

But Mubai was far from the hottest place in Asia...Makkah at 43c. 
Hottest in India today was Varanasi at 38c and Hissar was 37.7c....

Posted Saturday 27th:
Forcasted 35c for Sunday, but Mumbai Scruz reaches 35c on Saturday...Colaba was 31.8c and Vagaries 31.5c on Saturday.
Clear skies..
But, Mumbai does not have to loose hopes of the departing thunder shower !!
The LWD expected to move Westwards has delayed its movement...hopefully by Sunday or Monday, it will nudge West into interior Konkan, and bring thunder showers in the Eastern Outer townships and Navi Mumbai. 
Upper winds being Easterlies, will drift the thunder cells over parts of Mumbai City...But till then, Sunday would see 35c and Monday 36c..so gear up for some hot weather, possibly cooling down by evening !

21st September....Autumn Equinox for the Northern Hemisphere...( See Weather Report Below the Article)

Seasons are opposite on either side of the equator, so the equinox in September is also known as the "autumnal (fall) equinox" in the northern hemisphere. However, in the southern hemisphere, it's known as the "spring (vernal) equinox".

There are two equinoxes every year – in September and March – when the sun shines directly on the equator and the length of day and night is nearly equal.

The Earth's axis is always tilted at an angle of about 23.5° in relation to the ecliptic, the imaginary plane created by the Earth's path around the Sun. However, the tilt's orientation changes throughout the year. On any other day of the year, the Earth's axis tilts a little away from or towards the Sun. But on the two equinoxes, the Earth's axis tilts neither away from nor towards the Sun and is perpendicular to the Sun's rays, like the illustration shows.


Why is it called equinox?

On the equinox, night and day are nearly exactly the same length – 12 hours – all over the world. This is the reason it's called an "equinox", derived from Latin, meaning "equal night". However, even if this is widely accepted, it isn't entirely true. In reality equinoxes don't have exactly 12 hours of daylight
At the equinoxes, the sun appears overhead at noon as seen from Earth’s equator.
That’s why the sun rises due east and sets due west for all of us. The sun is on the celestial equator, and the celestial equator intersects all of our horizons at points due east and due west.

The September equinox occurs the moment the Sun crosses the celestial equator – the imaginary line in the sky above the Earth’s equator – from north to south. This happens either on September 22, 23, or 24 every year...It varies from place to place...
Although the equinox happens at the same moment worldwide, the clock times vary by time zone.
For example: September Equinox in India is on
Tuesday, 23 September 2014, 07:59 IST.
