Midnight Rains in Chennai, fair chance for evening rains today as well

In what is likely to set the tone for September Midnight rains in Chennai lashed many parts of the city with heavy & intense spells in a few areas.  The IMD observatory in Nungambakkam recorded 41 mm from these spells of rains in Chennai with the rainfall rate touching above 200 mm an hour recording about 35 mm rains in less than 30 minutes indicating the intensity of the rains.

While in our yesterday’s post we had indicated about possible rains in Chennai and surrounding places the intensity was certainly unexpected indicating the potential thunderstorms have as we get closer to the transition season of Monsoon.  If one were to see the sequence of events an important trigger was the strong sea breeze front to the North of Chennai that managed to possibly reach all the way up to about 100 kms inland.  Things are expected to be similar with strong sea breeze front expected to move in around afternoon that is likely to trigger afternoon / evening rains in a few places around North Coastal TN

With the upper Air cyclonic circulation still holding sway over West Central Bay we could see rains along the east coast with a fair chance of moderate to heavy rains in a few places.  As the system intensifies we could see more cloudy conditions prevail over the Peninsular India bringing down the temperatures in the region as well.

With the developing low pressure we could possibly see the rains return to West Coast as well particularly around the Konkan region as the moisture drags becomes more prominent.
