Meteorologist Joan Blackburn says people should brace themselves for some severe weather.
"A very cold snap will be occurring during the early part of Thursday, prevailing through Thursday evening, overnight and right through Friday, into early Saturday," she said.
"It's a cold north-westerly flow, it's going to being down a lot of showers, wintery showers, a mix of hail, sleet and snow."
