A frost advisory for the Niagara has ended this morning, but we may not be out of the odd spring weather yet.
Environment Canada says near or below freezing temperatures will continue this morning and we'll see them again Monday and Tuesday nights.
Frost and freezing conditions are possible and sensitive crops and plants could be damaged or killed.
Tonight's overnight low is only expected to drop to plus 2, but Monday and Tuesday an overnight low of -1 is currently forecast.
