New Delhi Sjung was a comfortable 25.1c, while Pune was 33.7c. Kolkata rose till 33.6c Friday....

March Outlook on Current Weather Page....

The last day of the month of February saw light rain/snow restricted to Kashmir and HP hills.

But, from the 1st of March, In the absence of any active systems, the weather is expected to be dry all over the India, Pakistan and Nepal from 28th February for the next 5 days, till 4th March.
Light rains in Kashmir and HP hills on 5th March.

Warming up from first Day of March:
No system dominates, so, the Upper Northern palins of the regions will have strong to gusty NW winds.
This will encourage the day temperatures to rise gradually. 





Delhi NCR: Clear skies.  
From the 1st of March, thereafter, a gradual rise to reach 29c by the 4th of March. Nights will be remaining pleasant around 12/13c till 4th.

First 4 days of March are forecasted to warm up in Central India due to Easterly winds. similar east winds will warm up the Gujarat and Konkan coast. 

Mumbai SCruz: Mumbai Colaba was a pleasant 30.2c today (Thursday), and Scruz was 33.8c..However, 
1st March to 4th March will see Easterly winds causing the days to rise regularly to reach 36c by 2nd/3rd March (Scruz). Low temperature will be around 20c.
Outer townships may touch 38c by the 2nd or 3rd of March.

Pune: Warm days with the days touching 37c by the 2nd or 3rd of March. Nights will also hover around 17/18c.

Region in the North Konkan, Madhya Maharashtra or Gujarat may soon see the first 40c of this year.
Vidarbha sees a rise to 37/38c in the first week. Goa should see a rise to 36/37c by Sunday.


Surat: Thursday Surat reached 34.2c. Warming gradually to reach 37/38c by the 2nd or 3rd of March. Bharuch also likely to warm up and reach 37/38 by the 2nd of March.

Kolkata: Seeing Thursday's high of 31.4c, we notice around 31c since last 3 days. I estimate the first 4 days of March will be maintained around 32/33c.

In Pakistan, Karachi will remain warm around 31/32c till 4th March, but we see Hyderabad (Sindh) heating up to 36c by Sunday.

An exuberant Birding trip to Thol, Gujarat, has been a very good experaince with a few lifers (seeing the bird for the first time)..an exotic water body with numerous water birds and the only place in India, where, in one location we get the big five, Storks, Cranes, Pelicans, Flamingoes and Geese. 
Album link put up in the "links" on the right of this page.

From Wednesday 27th, rising trend in day temperatures will be observed in Northern plains, Central, Eastern and Southern parts of the country. Central and Western India, see a marked rise from Thursday and Friday.

Do not miss Video at the end of this article

The 06UTC chart from PMD NMCC, shows F-3 getting "organised" and active over Pakistan. The trough, (WD) with the main primary Low is over Pakistan Sindh region, with the Northerly trough in the NE forming clouds over the North Indian regions. 



And Yes. Islamabad and surroundings had good rainfall last 9Thursday) night as mentioned, with 28 mms measured overnight. In the region, Mianwali was higher with 46 mms. Murree (35 kms away from the capital) received an inch of snow.

As expected, system will move into India tonite. Precipitation and cloudiness will increase as the moisture incursion towards the trough moves Eastwards. 
Saturday/Sunday map (below)on vagaries should tally (for rain and clouds).
The Low over Maharshtra is seen in the region also.
The Southern low over Kerala is short lived and may bring light showers in the Lakshdweep Islands region.
So, it seems, events may move as per yesterday's (below)estimate, and no changes in the forecast may be needed.

F-4 is also seen in the West, and the isobars are getting organised, almost to 2 mb difference between them..indicating the low getting strengthened. But, that is still vague, though entering into the Northern regions of the sub continent by the 26th seems certain.

There will be no blog published till Monday. I am away on a Nature and birding trip to Thol Bird Sanctuary, Mehsana, Gujarat next 3 days. 
FB inter actio will also be very much restricted. Vagarians requested to continue their inter action and keep other readers informed thru comments on blog.



In the meantime, I must share this amazing and absolutely superb video taken from the International Space Station. Another Incredible Timelapse from the ISS.
Covers so many aspects of our Earth's weather, and portraits a Space view of a silvery Moon setting into the Earth’s atmosphere, the dazzling Milky Way rising into a brilliant sunrise, airglow of all colors, popping lightning , shimmering aurorae, and incredible views of the stunning space station and our gorgeous planet.
Request all meteorologists and those who love Nature to watch this till the end....mark the lightning starting at 0.45 secs, Milky Way at 1.45, (i am sure you will not be able to leave it half way thru)

By 22nd, F-3 would be over India, initially covering Kashmir, HP, Punjab and Haryana. A East -West trough along the 20N line, could create some convection in the Vidharbha region on 22nd. 
**A low could possibly form on the North Karnataka/Goa coast on the 20th. This would move a bit inland, and get embedded in the trough.

A Report:
January 2013, which saw 5 Western Disturbances and a severe on amonst them. Would be considered a bit above normal, considering the fact that Northern Sub-Continent region normally gets 3/4 WDs in the month.

And the WDs continued in February. F-1 ,an intense system ravaged thru Pakistan in perticular wher the 2 days accumulated rainfall was more than 200 mms in the North and NW. In India too, it was intense, with several day and month records reached or broken in rainfall and snowfall. Delhi getting 46 mms in a day !
Vagaries has mentioned some details and references to this F-1 here...

In such cases, It is found that there is sharp increase in the convergence flux of kinetic energy and weak adiabatic generation of kinetic energy over the troposphere. The vertically integrated generation of kinetic energy shows destruction in the proximity of the center of low pressure area and generation take place west of it in the intense 
western disturbance.



 See the % of normal rainfall path", along the WD route..almost...



The accumulated rains chart for the sub continent for January shows the regions having received more than 200 mms, and the anomaly chart is also clear in its depiction.
