The first of two cold fronts crossed TAS today, with the second to follow tonight. Temperatures over the west coast are forecast to be in the low teens on Saturday - which would make them the lowest since early October. Even Hobart is only forecasting 14 on Sunday - 5 below average. Locations about the highlands will struggle to reach 5 degrees tomorrow, and a Bushwalking Alert has been issued for snowfalls developing down to 600 metres tonight. The front will also be accompanied by strong, gusty winds: 90 km/h gusts are already being felt about coastal areas of the north and northwest and these will continue tonight. The front will be followed by a frosty morning over the inland Sunday and Monday, before temperatures climb back to above average values next week.
