A severe thunderstorm watch was posted for Sarnia-Lambton Tuesday for the third time in four days.

Environment Canada said conditions were  favourable for the development of dangerous thunderstorms that may be capable of producing strong wind gusts and torrential rain.

The watch ended by mid afternoon.

Southwestern Ontario remained in a stagnant weather pattern Tuesday with sufficient moisture and unstable air to produce locally heavy thunderstorms.
