Weather Situation
A series of cold fronts will cross Tasmania overnight and on Tuesday, as a low slowly makes it's way south of the state. The low will quickly move away to the southeast on Wednesday morning, with a high pressure system over mainland Australia to direct a westerly airstream over Tasmania during Wednesday. A northwesterly airstream is expected to develop on Thursday.
