The temporary "Burst effect" of monsoonal winds in AS

 My meteorological Guru told about the WEAK establishment of 'MASCERE HIGH" in its normal position.  Further the strength of the other ensemble "High" near 90 Deg East is prominent.
This will give (pseudo) wind penetration in Arabian Sea.

It is clear SWM is dominant along 4 Deg North. [Mali] and in Andamans.



This sort of weather will enhance day time temperature further in the 'TEMPERATURE HOT BED "  locations in TN & Telengana and AP.  This is mainly due to continental-DRY westerly or HOT DRY north westerly winds from deserts in NW locations.
