After being under a rainy spell as July wound down Tamil Nadu Weather is set for a dry spell during the early part of August. This dry spell is likely to coincide with possibly the most active phase of Monsoon 2016 for many areas of the Monsoon Core Region. This revival of the active phase of Monsoon is being triggered by the Low Pressure Area that has developed over North Bay, just off the coast of Bangladesh / Myanmar. 
Just like how July started off on a weak note Tamil Nadu Weather is likely to see dry days for the early part of August as well. Numerical models indicate for the next few days possibly until the weekend most parts of Tamil Nadu will see fairly dry weather prevail. Only few places in the Western Ghats region and possibly extreme South Tamil Nadu could see isolated spells of rains. We will continue to monitor the developments if things change for the good. We are likely to see the dominance of Westerlies as well which could possibly play a role in the temperature & humidity pattern for places like Chennai in the days to come.
Konkan Coast has started becoming active once again with fairly widespread rains seen yesterday over the coastal areas of Maharashtra. Nerul a suburb of Mumbai has recorded about 108 mm till 5:30 in the morning while for the same period the IMD observatory in Santacruz has recorded 96 mm. Slightly south of Mumbai in the Raigad district the beach town of Murud has recorded 114 mm while Mahableshwar also has recorded good rainfall of close to 10 cms during the same period.
Things are expected to be similar today as well with many parts of Coastal Maharashtra & adjoining parts of South Gujarat expected to see widespread rains with heavy rains in a few places. One or two places in the stretch between Goa & South Gujarat could see very heavy rains as well. Under the monsoon moisture drag thanks to the Low Pressure in Bay some parts of Telengana & North Coastal AP along with adjoining areas of Odisha could see intense thunderstorms at isolated places.
