Killing frost forecast for tonight and Monday night

Unsettled Sunday

After a day of ice pellets and brilliant sunshine, Toronto faces an evening of potential killing frost. Those hardy enough to have planted their gardens had better cover the beds and if possible bring potted plants inside.  Environment Canada says below-zero temperatures will hit the region Sunday night as a cold air mass moves across the area. Windy conditions will mean that ice crystals forming on the ground will only be patchy, but plants could still be harmed as the ground temperature hits the freezing mark late in the evening or by midnight. Tomorrow skies are expected to clear but  Monday night is also expected to bring a severe frost that will kill any plants in the ground outside. Sensitive plants should either be brought indoors or covered up before Sunday evening when the frost is expected to hit. Picture shows the view north on Yonge St. from Davisville Ave. about noon Sunday revealing a sky that is ready to do anything. It had just dumped a three-minute rain and iice torrent. The day has seen brilliant sun and nasty wind whipped rain.
