Until to Saturday the doldrums lie over the region again with light low level winds and a steering flow somewhat from the north,this should lead to medium to high chances of of showers and thunderstorms especially in the afternoon/evening but I am hesitant to put very high chances due to the possibility of some dry air moving in aloft during this period.

Then from Sunday moderate northeast monsoon conditions with a steering flow somewhat from the east over the region as the Siberian High expands and the atmosphere will become more moist and unstable over the region altogether leading to high to very high chances of showers and thunderstorms.
