Discussion: Satellite view reveals a persistent low-pressure trough extending northward from low pressure off the Southeast Australia Coast maintains wet weather in East Australia with hefty amount continuing (Fig. 1). The latest 10-day outlook by GFS stays very wet in the East (Fig. 2). There are some signs that the unexpected wet weather regime may ease after 10 days.

In Europe, a cold pattern has evolved. North Atlantic oscillation (NAO) becomes negative and is maintained through the next 2 weeks. The 15-day temperature anomaly outlook is trending colder, and an expanding snow cover certainly helps that regime (Fig. 3-4).
