October 12, 2010 — Overnight lows are chilly throughout much of eastern Canada, prompting Environment Canada to issue frost warnings.

Protect your outdoor plants if you live in eastern Ontario, southern Quebec, New Brunswick, or Nova Scotia -- or else frost might get to them.

An arctic area of high pressure moved into Ontario on Monday night, dropping overnight lows significantly. So much so, that Environment Canada issued a frost warning Tuesday afternoon for much of the province.

Although it has been mild in southern Ontario during the day, overnight temperatures are cool. Below freezing temperatures combined with clear skies and light winds are the perfect ingredients for frost to form.

Frost was also possible in eastern Ontario early on Monday morning,but ground temperatures were a couple of degrees above freezing.

Frost warnings are in effect in southern Quebec for Saint-Jerome, Lanaudiere, Vaudreuil, and Richelieu Valley.

Most of New Brunswick and mainland Nova Scotia are also under warning, while other parts of Atlantic Canada have already seen snow.
