The Monsoon rains remain confined to the north of core Monsoon region, in response to the northward movement of the seasonal Monsoon Trough. The axis of this trough is a little south and running almost parallel to the Himalayas. This shift along with a circulation close to Bihar will generate moist convective process resulting in heavy to very heavy rains in parts of Sub Himalayan West Bengal, Sikkim, Assam, Meghalaya, Bihar and Arunachal Pradesh. The upper air cyclonic circulation over the Comorin area will move North Westwards gradually and weaken simultaneously. Dry conditions to prevail across Tamil Nadu for a day or two as a westward moving mid tropospheric High Pressure area would suppress convective activities.
Coimbatore to remain cloudy with a maximum temperature of 31-32 C.
Madurai to be less hot with maximum temperature touching 34-35 C.
