Posted Saturday Night:
A new Low forms off the Odisha Coast. Situated at 18N and 87E, it is about 1002 mb.
Arguably, it is not BB-2 as apparent. BB-2 had dissipated, as shown in our morning post chart.
Simultaneously, the predicted Low was mentioned few days back. It has formed in the trough running across North MP thru Jharkhand and Odisha.
Another point worth noting is that last mentioned location of BB-2 was 16N and 91.5E, barely 24 hrs ago...and the new Low is located at 18N and 87E, an very odd position for BB-2 to have "jumped" to (if it was the same)).
Low will move inland thru Northern region of Odisha, and due to prevalent moisture, bring very heavy rains in North Odisha and adjoining Bengal.
Due to the UAC in the WD trough, Punjab, Haryana and Parts of Delhi NCR can get thunder squalls on Sunday.
As the trough weakens, Monday would see isolated thunder squalls popping up in North Rajasthan, adjoining UP and parts of Delhi NCR.
Monday may see Thunder Squalls with rain in parts of Delhi NCR. Storms may drift into the Southern regions from adjoining areas surrounding South Delhi.
Monday's swearing-in Ceremony of the Prime Minister may see a 50% chance of a thunder squall, with gusty dust raising winds. Partly Cloudy day.
