[1] As expected the low entered the Bay and a trough formed in the Bay. [Pre-] Monsoon trough !

[2] It may attract SWly wind through / across TN if and only if it drifts again towards west again.

[3] Contrary to it if the NWly winds are strong and if it drifts towards EAST temperature will increase in North Tamilnadu.
