Chennai Weather to stay warm, chance of isolated light rains exist

It is quite clear Chennai Weather has been getting back to normal over the last couple of days.  The second fortnight of June saw Chennai Weather show some abnormality in terms of temperature trends.  The day time temperature was pretty much consistently below normal.  On more than one occasion the day time max temperature struggled to cross 30 degrees which does not happen always during June particularly around the coastal areas unless there is synoptic condition existing in the region.  The near continuous synoptic condition in terms of UAC / LOPAR etc meant we were pretty much having cloudy conditions continuously keeping temperature under check.

The graph pretty much shows how Chennai Weather was under the influence of these synoptic conditions. Similarly it clearly indicates the increasing temperature trend as well over the last couple of days indicating the dry spell for us.

Weather_Update_1

Temperatures are expected to stay on the higher side today as well with a narrow band of region starting from North Interior TN around Tiruvallur & running all the way up to Madurai in near continuous fashion expected to stay around 38 / 39 degrees making it a very hot day for these places.  Rest of TN all the way from Coast till most of interior regions the temperatures will stay higher than 35 / 36 degrees with the exception being Kanyakumari & Coimbatore district in the plains which could see lower than 35 degrees mostly.

Weather_Update

There is some chance of isolated rains in North TN and adjoining parts of South AP as day time ground heating could create possibilities of convective thunderstorms.  The possibility of sea breeze coming in around evening could aid these thunderstorms as well.  Otherwise most of Tamil Nadu is likely to be dry.  The extent of dryness in Tamil Nadu could be understood with the rainfall numbers till early morning today,  Chennai Nungambakkam which got about 2.5 mm from the isolated storm yesterday has recorded the highest amount of rains among the IMD automatic weather stations.

Most parts of Konkan Coast and some areas of Gujarat south coast could see isolated heavy rains particularly around the ghat regions of Shayadri hills.  Similarly East Coast could be under a spell of heavy rains under the influence of the Low Pressure now lying off the Odisha / Gangetic West Bengal coast.
