Just two days after 30 degree Celsius daytime highs in the region, the Southwest is expecting frost on Tuesday night and Wednesday morning.
Environment Canada has issued a frost warning for the Swift Current - Herbert - Cabri - Kyle - Lucky Lake, the Leader - Gull Lake, plus the Shaunavon - Maple Creek - Val Marie - Cypress Hills.
During the mid afternoon hours the Southwest was experiencing 50 kilometer per hour winds, with gusts as high as 70 kilometers per hour. However, when the winds lessen this evening, the temperature is forecast to drop to -2 Celsius in Val Marie, Shaunavon, Eastend, Maple Creek and the Cypress Hills, and zero in Swift Current and Leader.
The Environment Canada warning notes:
"Strong west winds have developed over Southern Saskatchewan this afternoon under the influence of a deep low pressure system in the north. The strongest winds will continue throughout central portions of the northern grainbelt. Wind gusts at times to 90 km/h are still possible this evening before diminishing as the low moves off into Northern Manitoba.
"In addition, the cold Arctic airmass ushered in by the system will bring frost to the southwest corner of the province tonight as winds become light and temperatures dip below the freezing mark. This cold air will linger through Wednesday and will bring additional frost warnings tomorrow night across most of Southern Saskatchewan.
"Wind warning criteria are sustained winds of 70 kilometer per hour or more and/or gusts of 90 kilometers per hour or more. Frost warnings are issued when overnight temperatures are expected to drop below zero degrees Celsius.
