Much of SA is having its coldest day of the year and wind, rain, hail and snow are making it feel as cold as it gets. The coldest day of the year has delivered snow to the peaks of Mount Bryan, near Burra, in the state's Mid North. Snow has reportedly fallen as low as 800 metres as the temperature dipped to near freezing. Heavy, squally showers and hail have contributed to the chill. Just after midday some of these hail showers chilled Adelaide and its suburbs to eight degrees with wind making it feel like four-or-five degrees. In the Hills it was only five degrees and felt more like one degree. As of 2pm Adelaide had stayed colder than 10.4 degrees, so far the only day that has stayed colder than 11 degrees in two years. The last time the city stayed colder than 10.5 was in July 2005. However, some dry breaks and glimpses of sunshine between the showers give an opportunity for the city to briefly 'warm up' past 11 degrees before the day is done. Nevertheless, today feels as cold as it gets in any winter. Intense low pressure systems have been forming in cold air in the wake of yesterday's front, sending bursts of very strong winds across much of the state including squally showers and small hail across the south. Apart from in the north of the state, today is generally not as windy as yesterday, when the front generated gusts in excess of 115km/h at Port Lincoln and 90km/h in the Adelaide area, but gusts still have the potential to be damaging later today and tonight. One more significant low is due to cross the southeast of the state later today, bringing another round of heavy, squally showers, small hail, very strong winds to its north this afternoon and evening. Sleet or even snow on Mount Lofty cannot be ruled out. By Thursday morning the south of the state will have accumulated widespread 10-40mm of rain over two days with over 70mm in some areas, including the the Adelaide Hills, leading to some flooding. So far parts of the West Coast have had more than half of their monthly average with 20-40mm. Elliston's 30mm is a one-year high. The driest and calmest area of the state has been east of the Mount Lofty Ranges where rainfall has been as little as five millimetres and gusts lower than 50km/h. Thursday will be a day of easing wind and clearing showers but Friday will be a day of increasing wind and returning showers. Wind and showers are due to peak on Friday night, although it won't become as wet or as windy as earlier in the week. The weekend will be much calmer and drier but just a bit warmer. The chill will be mainly nights and early mornings, maintaining the need for coats, gloves and scarves.
