Forecast issued at 4:05 pm EST on Wednesday 23 September 2020.

Weather Situation

A low pressure system to the east of Tasmania moves away this evening, directing a cool southwesterly stream over the state. A weak ridge of high pressure will move over Tasmania Thursday morning before another low and associated cold front arrive in the west late. The cold front will cross Tasmania on Friday, and a broad area of low pressure will linger over the state before consolidating to the northeast in the evening, bringing another burst of cooler southwesterly winds. Winds freshen on Saturday as a cold front embedded in the southwesterly stream crosses the state, and a high develops south of the Bight. The high will move over Tasmania on Sunday.
