Environment and Climate Change Canada has issued a frost advisory for Windsor, Leamington and Essex County tonight, followed by a long stretch of sunshine and above-normal temperatures.

Tonight

Clear skies and a low of plus 2, with a risk of frost. The yellow frost advisory, issued at 2:57 p.m. Saturday, says patchy frost is expected tonight, with temperatures falling to near the freezing mark for areas inland from the Great Lakes. Light to moderate southwesterly winds overnight may prevent frost in some areas. Environment Canada says damage to plants, trees and crops is possible and advises taking steps to protect cold-sensitive plants.

Sunday

Sunny, with wind becoming southwest at 30 km/h, gusting to 50, in the morning. The high is 15. Sunday night is clear with a low of plus 4. Sunday morning is also the Detroit Free Press Marathon, which closes the Windsor-Detroit Tunnel and several downtown Windsor streets for part of the morning.

The week ahead

Monday, Tuesday and Wednesday are forecast to be sunny with highs of 18, with clear nights and lows of 3 to 8. Thursday is sunny with a high of 18, then clear overnight with a low of 6. Friday is sunny with a high of 17.

How that compares

The normal high for this date in Windsor is 14 and the normal low is 5, according to Environment Canada, so most of next week is forecast to run about 3 to 4 degrees warmer than usual during the day.
