Flash freeze warning posted for southern Quebec Tuesday evening
Temperatures soared into the low teens in Montreal on Tuesday, on strong and gusty south winds between 30 and 50km/h. The high reached 15C (59F) on Ile Perrot, slightly lower at Trudeau Airport, with 12C (54F). The record for the date was 11.8C (53F), set in 2021. Clouds have been on the increase all afternoon, as a strong cold front is moving east across Ontario towards Montreal.
A flash freeze warning has been issued for southern Quebec, with temperatures expected to fall rapidly behind the front. Winds are forecast to back to the west, and gust between 40 and 60km/h Tuesday evening. Showers will develop along the front and briefly mix with wet snow before ending by midnight. Any standing water will freeze as temperatures fall below freezing, down to -11C (12F) by morning. Windchill values will approach -18C (0F), a nearly forty degree plunge from Tuesday afternoon's high temperatures.
Wednesday will be blustery and chilly, with highs near -3C (27F). The good news is that the cold snap will be short-lived, as very warm temperatures along with rain return by the weekend. However, the threat for flooding will be on the rise as ice and snow across the region begin to melt quickly.
