Rainfall Activity over South India to wind down

The Rainfall activity during the last few days over South India under the influence of the depression over Arabian Sea is expected to wind down.  Yesterday  saw many parts of Kerala record good rains along with parts of South Tamil Nadu in particular along the Western Ghats.  The models expected wind convergence to happen over the Eastern Side of Western Ghats while the convergence happened over the Western side increasing the rainfall over Kerala and reduced chances for Tamil Nadu.

Looking back at this spell of rains it has been certainly fruitful as far as numbers go though some of the farmers who were affected by the unseasonal rainfall & possibly the people involved with the Salt Pans at Thoothukudi may have preferred this rains not to happen.  The last 5 days of rains have added nearly the entire March quota to the Daily Rainfall Graph.

Today also models indicate a weak convergence activity over the areas along the Western Ghats though the effect is much less compared to what models estimated yesterday.  This will once again trigger some rainfall activity along the ghats with isolated places in the Palani Hills & Nilgiris seeing heavier spells of rains.

Unlike yesterday which saw partly cloudy skies over larger parts of Peninsular India today relatively clearer skies could prevail improving the chances of convective evening thunderstorms assisted by the wind convergence.  Due to this factor one or two places in Western TN could see a spell or two of heavy rains though model outputs do not indicate any major rainfall activity in the region. Isolated places in South TN could see moderate rainfall activity like yesterday particularly in Kanyakumari & Tirunelveli districts.

Rest of Tamil Nadu is going to be relatively dry with possibly the temperatures starting to climb up as well under clearer skies.
