There was a marked decrease in temperature across the state on Tuesday with rain occurring at a few places in Rayalaseema and isolated rain in coastal Andhra and Telangana under the influence of a trough of low pressure that has formed over the coast from N. Andhra to South of Tamil Nadu. Besides, a low pressure area forming over the Bay of Bengal added to the change in the weather condition. Light to moderate rain or thunder showers would occur at a few places over Coastal AP and Rayalaseema and rain or thundershowers in Telangana.
