The days are getting warmer, especially this week with temperatures in the daytime reaching as high as 25c over the next few days, but the overnight period can still get quite chilly. In fact a high pressure system sitting over the great lakes could keep us a little chilly when the sun isn’t out. Environment Canada has issued the following advisory :
Frost advisory in effect for:
Agawa – Lake Superior Park
Sault Ste. Marie – St. Joseph Island
Searchmont – Montreal River Harbour – Batchawana Bay
Some plants may be damaged or even destroyed by frost.
Clear skies and light winds will allow temperatures overnight to drop to near zero degrees. This will result in the formation of patchy frost overnight.
Cover up plants, especially those in frost-prone areas.
Frost advisories are issued when temperatures are expected to reach the freezing mark during the growing season, leading to potential damage and destruction to plants and crops.
