Parts of Chennai receive rains, Convective Activity to pick up in Tamil Nadu

Parts of Chennai recorded good rains last night in particular places in South Chennai and suburbs like Tambaram received two separate spells of moderate to heavy rains.  The IMD Observatory at Chennai Meenambakkam recorded 36 mm till 5:30 in the morning topping the rain charts.  Similarly places like Taramani also recorded good rains.

On Tuesday the rains were more scattered with few light spells of showers hitting the city though the better spells of rains went South of Tambaram and North of Chennai closer to Pulicat Lake.  Yesterday more areas in the city got spells of rains though the central areas like Nungambakkam and the rest of the Northern areas missed out.  But these are indications of how things are likely to shape up as convective thunderstorm activity is expected to pick up in the coming days.

The trend of hot days is likely to continue with no immediate respite seen from the models.  Yesterday Madurai saw a maximum temperature of 42 degrees with many places in Tamil Nadu seeing day time temperatures well in excess of the average for this time of the year.  Today is likely to be no exception with South TN in line once again for scorching conditions with all of Tamil Nadu possibly seeing above average temperatures.

The depression that is currently over Jharkhand is moving from East to West giving rains over parts of Bihar, UP & MP in the next couple of days.  Subsequently it is expected to give another round of rains to Gujarat and Rajasthan before it fades away.  Most models are fairly in agreement Monsoon could head for a break once this disturbance completes its life cycle.

In the immediate context we are likely to see convective thunderstorms slowly increase over parts of Tamil Nadu with coastal Tamil Nadu in line for another day of thunderstorms today in the evening.  Models are indicating few places in North Coastal TN in line for some moderate to heavy rains while the thunderstorms pass from interiors to the coast.  As we always say chances for any place will depend on the initial genesis of thunderstorms and the subsequent wind directions.  So the chance for Chennai will be the same as any other place as models indicate the stretch between Pondy and SHAR ideally placed for these thunderstorms.
