Chennai Temperatures Under Check, Isolated Rains in North TN

Thanks to last evening thunderstorms in the suburbs of Chennai Temperatures in the region has come down a notch to make up a pleasant and cool morning for the weekend.   Overall the temperatures have been pretty normal so far this June with only Tiruttani crossing 40 degrees more than a couple of times with Vellore seeing 40 only on the first day of June and subsequently enjoying more comfortable weather mostly.   Yesterday evening saw Southern suburbs of Chennai receive rains particularly the places to the South of Tambaram received a good spell of rains.  Places like Thiruporur in OMR also received spells of passing showers.

From today we are adding a new feature in terms of Southwest Monsoon – Performance Chart which will provide an indication of the performance of Southwest Monsoon 2016 based on daily rainfall data from the core Monsoon region as identified by IMD.

As one can see so far the daily rainfall data has been showing only negative anomaly indicating the weak monsoon state as of now.  This though is expected to pick up in the coming days once proper monsoon onset happens consequent to the twin disturbances developing on either side of Peninsular India

Cloudy skies is expected to prevail over most parts of South India which is likely to keep temperatures under check.  While North Tamil Nadu could see partly cloudy skies the absence of strong ground radiation from the west could possibly keep the temperatures lower over the coastal areas while the interiors are likely to enjoy the benefit of the remnant thunderstorms that have been pretty much happening regularly over the region.  Partly cloudy skies and the possibility of moderately strong Sea Breeze by noon is likely to keep Chennai Temperatures also under check for most parts of the day. Weather_Update

Coastal Andhra Pradesh is likely to see rains continue under the influence of the Upper Air Cyclonic Circulation around Bay of Bengal which is also providing for some wind induced instability in the region in the form of continental dry air and moist Bay air that is mixing up things in the region.   Some parts of North Tamil Nadu could see isolated rains which is likely to be triggered by sea breeze of moderate strength that is expected to move inland to about 50 kms or so.  The remnant moisture that is being pushed across the peninsular India will possibly aid the formation of thunderstorms in the region.  With favourable winds few suburbs of Chennai could get isolated rains.
