Weekend Weather

Radar is showing a gusty cold front moving across the St. Lawrence Valley this morning. The front is producing the first appreciable rain of the month in Montreal, (only 0.4mm to date at Dorval) right at the morning rush. The heavy showers will move southeast of the region, followed by a second line later this morning. Skies should clear by noon with a windy and chilly afternoon and evening. The weekend will be sunny, dry and seasonable with temperatures near 18C. Overnight lows will be cold enough for frost north and south of Montreal and in rural areas of central and eastern Ontario. Monday will be very warm for September, a high of 26C for the last full day of summer 2009. Summer had a nice recovery thanks to September.

Speaking of heat, Saskatchewan was baking yesterday. Numerous record highs were smashed including 37C (100F) in Rosetown. That was after an overnight low of 11C or a whopping 49 degree Fahrenheit difference. What a temperature range for a 12 hour period. The previous record was 31.5C set in 1981. Other records included Moose Jaw, Swift Current and Leader. Temperatures in Gravelbourg and Assiniboia were around 33C. More heat is expected this weekend before a slight cooling trend next week.
