The new Low in the Bay, BB-20, scheduled to form on 3rd November as mentioned in Vagaries and likely around the same predicted spot..West of The Andaman Islands.
Initially at 1008 mb, BB-20 will deepen very slowly, as it is just South of the Sub Tropical Ridge. The current STR is strong, and runs East-West upto the Arabian Peninsula.
Initially for the next 3 days, Monday, Tuesday and Wednesday, it could be said theat the BB-20 may not go below 1005 mb, hence even the system may not reach above a height upto 700 mb wind levels. Hence may just "loiter" around the Southern Bay for a few days. As the STR gets to dominate the region, we may see BB-20 trying to "scramble" towards the North after Thursday.
Since, the system is far from the coast, we may see a decrease in rainfall in TN . Rains may be scattered in coastal TN and Southern Kerala.
City Forecasts for Monday 3rd/Tuesday 4th and Wednesday 5th:
Meanwhile, Chennai will may get a thunder shower on Sunday night or Monday early..decrease after Monday evening.
Bangalore: Partly cloudy with temperatures in the 28-18c range.
Kolkata: Almost clear...with crisp N/NW winds by evening..Nights going down a bit to 19/20c.....
Mumbai will be sunny and warm...days around 35/36c and nights a shade better at 21c....Sunday's Maximum was 35c.
Pune: Days will be around 31/32c. Nights will be nippy at 15/16c.
N-1, restricted to the upper levels, will not precipitate much in the Indian plains. On Monday, rain/snow will be precipitating in the Northern Hills of the Sub Continent, and Northern Pak Punjab. Islamabad can get showers and a cool day on Monday and Tuesday.
But, the WD moves away by Wednesday, without precipitating in the Indian Plains. Will anticipate N-2 on the 9th.:-)
Delhi NCR will see hazy sunshine. Foggy on 4th Night/5th morning.
