Weather Situation

A high over Tasmania will moves away to the east this morning, with a northerly stream to develop and gradually freshen, then strengthen on Thursday bringing warm to hot temperatures across Tasmania. A cold front will slowly cross the state during Thursday, with a cooler westerly change to follow, though not reaching the northeast until late. A weak ridge is expected to pass over the state early Friday before another cold front nears the west of Tasmania late. As the front crosses early Saturday, a westerly flow will follow and a trough is expected to linger about the north.
