Mumbai:

The warming up of the Mumbai region started this weekend from 26th January,  and Santa Cruz touched a high of 34c on 27&28th. Now, expected to reach 35c by 30th. The upward trend seen here, is due to the change of wind direction to an unseasonal shift to SE and Westerly.

Karjat 35.4c

Kalyan 35

Badlapur 34.8

Navi Mumbai 34.7

With the advent of a much awaited Western Disturbance (WD) in the North from 30th. With another back to back WD on the 2nd of February, Mumbai will be swept by the cool and welcome North winds from 1st.

 24th January...Evening 

Mumbai Air Quality..Improvement seen

Vagaries had explained earlier,when AQI in Mumbai was "poor" at 200+, that the deterioration is dye to the trapped air due to " Air Inversion ". A meteorological phenomena. That explained the trapped pollution for 4/ 5 days.  Or the accumulation of pollution due to no winds.

As the winds strengthen,  and the North West winds commenced this Month, Mumbai saw a marked improvement in the AQI, air quality. The figures below indicate a fairly stable and tolerable quality of air in Mumbai.

Silent are the complaints and blames now.

As is said, " one sees only the ⚫️ dot on the white screen " 😉

Weather forecast from Wednesday 24th to Sunday 28th January

Mumbai: Dry weather with cooler nights to continue till 25th/26th January. Days to be around 31C and nights around 15C. Temperatures to start rising from 26th January, with days getting hotter to around 34C by the weekend and nights can remain around 18C. 

Interior konkan will see cooler nights, but hotter days than Mumbai. Daytime temperature can touch 35C by the weekend in interior regions of Thane/Palghar/Raigad/Ratnagiri districts. 

Pune: Very cool nights of around 10C to continue for another day or two. Night temperatures to rise to around 15C by the weekend, with days also getting warmer to 32-33C. 

Winter is not over yet and another round of cooler weather can be expected in the next week. 

The exceptional dry phase for Western Himalayas is finally about to end. 

A weak Western Disturbance will give light-moderate snowfall in the higher elevations during 25th-26th January, with the most chance for Kashmir, Ladakh and northern Himachal Pradesh (Lahaul/Spiti). 

A slightly stronger WD is likely around 28th January, with the heaviest precipitation in Jammu, Kashmir, Ladakh and northern HP regions. Uttarakhand will get rain/snow mainly in higher ranges.

 North India Fog...19th Morning

17th January 

Mumbai:

The East winds shifted to North West direction. Resulting in

*On 16th/17th of this month, a short spell of pleasant temperatures ( 16/17°). 

* An improvement in the bustling City's air quality. The Air Quality Index fell from " Poor" ( 175) to "Good" ( 80).

This is chart on 16th...👇

All this brought smiles 😃 

-------

Now, as the NW winds are going to relent, we may see the Air Quality Index rising again ( 140).

Today's chart 👇

OUTLOOK :The temperatures this week till 21st may remain in the range 

Day: 30/31° (Normal)

Night: 18/20° ( Slight above normal).

Pune

Outlook: Pune may still see some warm days around 31° and pleasant nights at 12/14°. 

Single digit still avoiding Pune.

----------------------------------------------------

*North India*

A strong Jet Stream across the North Indian plains, with winds at 150 knots,  has caused an High Pressure Region ( due to convergence).

This has resulted in

* Thick fog in the plains 

* Sharp drop in day and night temperatures. Almost sub zero temperatures. 

*The places in the plains of Punjab, Haryana, Rajasthan and Delhi are colder than the Himalayan hill stations at night.
