Sharing a past Similar Weather situation..Chances  40% of it happening tomorrow..

Vagaries has projected a vortex (see below)  around the interior Karnataka region by tomorrow, Monday. This will be the result of a bloated (non effective) low region of 1008 mb covering entire South India. The vortex will form on Tuesday within, temporarily.

Now, out of interest, i went thru certain similar situations. I checked, that on some occasions a line of wind dis-continuity forms north of the vortex. 
That is when the low region was big enough. 
In such a case, the cloudings from the vortex can stretch into interior Madhya Maharashtra and along the Karnataka and Maharshtra Western Ghats. Maybe on Monday or Tuesday. 

Please note, I am sharing a past weather occurance, and chances of vortex spreading its clouding North are 40% as of now ....may or may not happen...

Rest forecast given Below in yesterday's blog..

Badlapur was having 19 C as min temp @ 6am today morning. Today Badlapur having one of the very thick denser fog covered. Actually light fog started to fall after 12am onwards only then from 6am onwards it is increasing and increasing. Now 7.40am but fog intensity is at it's peak level. Sun looking like moon here. And no sun rays are falling on ground. No vehicles on road can be seen just sound of vehicles can be heard.

Unknown said...

today morning nasik temperature was 13 Degree's celcius. this clearly shows some parts of maharahtra are much cooler then delhi, for delhi being 15 degree celcius in the morning.

Unknown said...

western ghats n konkan areas including some parts of Goa are likely to experience , thundery activity, for 2 - 3 days.

Rajesh said...

Tuesday Morning: Lodhi 12.4c, Gurgaon 12.5c, Faridabad 13c and S'Jung 13.8c.
Nasik (Mah) 12.3c..

Wednesday was the day predicted by vagaries..started on Tuesday..

Abhijit Modak said...

Also reports(announcement was going on Mumbai CST station) came at 9am from Mumbai CST Railway station (Central Railway) that due to thick fog cover between Karjat- Badlapur- Kalyan route so local trains from that section are running late and so arriving late towards CST station.

Rajesh said...

Vagaries' Maximum today (Tuesday) 30.9c..not bad..

Abhijit Modak said...

Badlapur max temp continues to be at 33 C today also .

sset said...

Rajesh Sir - Will NE monsoon revive over TN or this is the end? As of Oct average rain over TN is just 300-400mm far less than normal average rain of 1000mm.

Pradeep - thanks for readings, wish North AP rains would have come to TN.

Thanks

Unknown said...

chances are very low for TN to reach 1000 mm this year, but one can never say hw the weather might change .anyway good luck.

Abhijit Modak said...

Today light fog here in Badlapur as visibility is above 3kms.

Yesterday's alto cumulus clouds over S. Madhya Mah moved more north and today morning Badlapur also having few patches of clouds presence.

Today Badlapur having 19.3 C as min temp & nearby IMD's Karjat AWS showing 18.7 C @ 6.30am.

@ Rajesh Sir.So as per sat image whether today convective rains possible for S.Madhya Mah including Pune region ?

And instead of east coast(i.e Chennai looking dry for next 5days or may be just light shower ) now West coast looking like active along Kerala , Coastal Karnataka & even up to some extent till Goa for next 72hrs at least !

Abhijit Modak said...

Pune's min temp raised today to 18.2 C from yesterdays min 15.6C ! So cumulus clouds hovering last night responsible !
