AS TEMPERATURES dipped below 0 degrees overnight Kingaroy recorded its coldest May morning in five years.
The mercury plummeted as low as minus 0.8 degrees at 6am on Friday, not reaching the 2010 low of minus 2 degrees, but about two degrees colder than overnight temperatures so far this year.
Residents around the region left the house to find cars, lawns and paddocks coated in frost.
Higgins Storm Chasing reported instances of rare black frost in parts of inland southern Queensland yesterday morning.
According to the Bureau of Meteorology black frost develops when the temperature drops to freezing point but the air does not contain enough moisture to form white frost on exposed surfaces.
This causes internal freezing of vegetation, leaving it with a blackened appearance and killing it.
While the white frost made an appearance around the South Burnett this morning the forecast is for warmer minimum temperatures in the coming days, with lows of between 8 degrees and 10 degrees expected alongside highs in the low 20s.
Types of frost
- White frost occurs when ice crystals form on objects exposed to the air.
- Black frost forms when the temperature drops to freezing point but there is little moisture in the air.
- Killing frost is severe frost that ends a growing season.
- Rime is a deposit of ice formed by the rapid freezing of super cooled water droplets.
