Parts of Tasmania have just been hit by their first severe frost of the season with temperatures plummeting as low as minus five degrees, 10 below average. For some it was the most severe April frost in four years. The thickest frost overnight and early this morning was in eastern, central and northern parts, where many centres recorded their lowest temperature since last September. Fingal, Ross and Cressy all had their coldest night since last winter with a minimum temperature of -4.6 and minus four degrees respectively, 10 degrees below the April average. This was also the coldest April night in four years for Fingal and Cressy. The chill was brought about by winds becoming light and skies clearing rapidly in the wake of one of the strongest cold fronts of the year. Not quite as cold but still the coldest since spring, Launceston recorded a minimum of 0.5 degrees, seven below average. Hobart got off lightly with a minimum of eight degrees but wind chill made it feel more like five degrees, even at 7am this morning when most were rugging up and heading out for the day. The next best chance of severe frost in similar areas is this Wednesday night/Thursday morning in the wake of another strong cold front. Another potentially strong front early this weekend brings a risk of further severe frost on Saturday night/Sunday morning. Both fronts will also bring snow to the highlands. Gloves and beanies will get plenty of use in the coming days.
