In Northern India, M4 effect continues into 2/3 June.
In H.P, snowfall in the higher reaches and intermittent rain in low and mid hills on Thursday brought the temperatures across the state to comfortable levels, weather officials said.

"High-altitude areas of Lahaul and Spiti, Chamba, Kullu and Kinnaur districts experienced moderate snow early Thursday," a met department official said.

Keylong, experienced 18 cm of snow. Manali experienced 43 mm of rain Thursday, while Rohtang Pass, just 52 km from Manali, experienced mild spells of snow. Shimla (43.6 mm) and its nearby hills like Narkanda experienced good rainfall.
Shimla recorded a low of 10.1c, while it was 4c in Keylong, 4.2c in Kalpa.

Higher reaches of Uttarakhand including the shrines of Badrinath, Kedarnath and Yamunotri received snowfall

It was wet in Punjab too. Patiala saw a heavy downpour of 53 mm, with the minimum settling at 19c, down six notches. Amritsar received a rainfall of 13.8 mm and the minimum dropped to 18.2c,5c below. Ludhiana received 18.8 mm of rains, and the minimum settled at 18.8c,7c below normal.
Ambala was the wettest place in Haryana after being lashed by 47.4 mm of rains. The minimum there settled at 18.3c, down 7c, while it recorded a high of 31.9c, -9c below normal.

Parts of Rajasthan had moderate rainfall. Churu, Pilani and Bikaner received 19mm, 8 mm and 6 mm rains respectively.

SWM should have no problem scaling up to 20N. After this point, in view of the impending "threat" from M4, I would review the further advance of the SWM.

Update on AS-1. At 15.8N and 68.7 E, its a low off the Goa coast, a little more to the west than the previous location. Concentrated clouding is seen in the western/South-western quadrant. At 1002 mb, and embedded in the off shore trough now, AS-1 will deepen slowly, and track NW.

The off shore trough should remain intact, and gear up the SWM to move into Goa.Likely by Sunday.

Imd has declared monsoon over goa. It says that low will form off konkan coast in next 48 hrs. Will Mumbai will get heavy monsoon rains (like south konkan) from mon/tuesday or if low moves northwest then mumbai to get only moderate rain !

The Low as per the Thai map has done 2 things, one is it has increased it's pressure (reduced in intensity) and second is it has moved North East in the last 6 hours. Based on the models and IMD's forecasts it appears that it will come closer to the Konkan coast, intensify and then start moving NW. If this is indeed going to be the situation then Mumbai should get heavy rains over the weekend before they taper off as the Low moves away. The Monsoon should get declared in Mumbai in this case by Sun - Mon

Latest Thai map (1000 IST) shows the LP completely gone !! ECMWF also has removed the LP. Invest 98A still exists in US Navy weather. All very confusing at this moment.
Waiting for our weather guru to throw further light on the paradox.
