Fluctuating temp. trend to continue for another day or so

Weather Update

The winter this year has been sub par across Peninsular India with no major cold spell so far. With just a couple of days left for last week of February to come in chances for any cold spell further on looks less likely. The last few days have seen relatively cool mornings along the coast and fairly cold morning in the interior areas.

Days though has been warm bringing diurnal variation in temperatures between night time minimum and day time highs to above 15ºC over the last few days. Places like Valparai has been seeing 18 / 19ºC difference between the high & lows. Tomorrow once again the interior parts of Tamil Nadu, in particular over West Interior and South TN could see day time maximum temperatures stay a couple of degrees above normal while places in Central Kerala may seen 3 to 5ºC above normal day time temperatures.

The nights / early mornings will remain cold over the interiors until Thursday post which the returning Easterlies will start modulating the night time temperatures bringing back the warm and humid nights under the influence of moisture incursion from the Bay. Coastal areas though will start seeing the effect of Easterlies tomorrow morning thereby seeing a slight increase in night time temperatures compared to the past few days.

Weather models are fairly in sync about a possible spell of rains on Friday / Saturday over coastal areas of Tamil Nadu. It appears parts of South TN & Delta may be the biggest beneficiary of this spell as things stand though we will put a clear update on Thursday on what to expect on the rain front.
