Frost is in the forecast for parts of Newfoundland.
Environment Canada made the announcement Saturday evening, warning of high-pressure south of the island.
On Sunday morning, clear skies - mixed with light winds - sent temperatures plunging towards the freezing mark.
Parts of the interior saw some patchy frost, but it melted quickly as conditions returned to seasonal levels.
The frost is expected to make another appearance tonight in the interior and western avalon.
"Frost in Newfoundland isn't common this early in the year, but it isn't unheard of, either," says Brian Dillon, a meteorologist at The Weather Network. "Newfoundland's first frost usually appears in mid-September, so we're a couple of weeks ahead of schedule."
St. John's will be spared for now. Tonight's low is expected to be 7°C -- more than double the frost threshold.
Dillon recommends that residents cover their outdoor plants this evening to protect them from the conditions.
