Weather Situation

A ridge of high pressure is weakening over the east of the state today. A low pressure trough is moving into the west of the state this afternoon and is expected to continue to progress east during the next couple of days, generating showers and thunderstorms across much of the state. Within this trough a transient low pressure system may deepen off the southern coast mid-week as a strong high pressure system develops well to the south. This pattern has the potential to bring a period of heavier rainfall and stronger winds to the southeast, although there's uncertainty around the system's precise evolution. Meanwhile, a new ridge is expected to restore mostly dry weather over the state's interior during the latter part of the week.

The chance of a thunderstorm, possibly severe with damaging winds in the southwest. Winds northwest to southwesterly 15 to 25 km/h tending southeast to southwesterly 15 to 20 km/h in the evening.
