Thunder Bay - The deepest, longest cold snap of the season is about to hit northwestern Ontario.
Environment Canada says it could lead to an extreme cold warning for the Thunder Bay area.
Meteorologist Trudy Kidd said Wednesday that a cold front moving into the region will bring a "continuous stream of Arctic air" over an extended period.
Forecasts currently call for overnight lows near -30 C starting Saturday night, with similar overnight temperatures expected for at least the next two days.
By Monday and Tuesday, daytime highs will only reach -23 C, 14 degrees below normal.
But the wind will make things very uncomfortable and potentially dangerous for exposed skin.
"It's going to be very cold... at times it will feel like it's below -35 C, possibly even -40 C," Kidd said.
"When the temperature or wind chill reaches -40 C, an extreme cold warning may be issued. But even if it doesn't meet the extreme cold criteria, people should remember to dress in layers and check on elderly family members, friends, and neighbours."
She said the cold snap could last until next Thursday.
"Be sure to dress warmly and in layers. If you work outside, take regular breaks to warm up."

桑德贝即将迎来今冬第一次真正意义上的超强寒潮，从现在开始到明天这个时候，短短24小时内气温将下降超过20℃，相当恐怖。（中国强寒潮标准：24hr气温下降12℃以上） 桑德贝地区冬季的天气主角是从艾伯塔省移来的一个个温带气旋，又称为“艾伯塔快船”（Alberta Clippers）。今天白天桑德贝正位于一个Clipper东侧的西南风（暖湿）区域，气温显著回升至0℃左右，地面积雪部分融化；而随着Clipper东移，目前冷锋正在逐渐靠近桑德贝，迫使暖湿气流在锋前局部地区急剧抬升形成刚刚结束的短时强降雪，有点类似于夏季的短时降雨，来去匆匆。 预计今晚入夜后冷锋就将过境桑德贝，其标志是风向逐渐转为西北风+风力迅速增强+气温断崖式下降。根据预报，今晚桑德贝最大阵风可达6-7级（50-60kph），冷锋过后阵性的小降雪也将断断续续直到深夜结束。今夜出行除了防范大风降温，也需要注意今天部分积雪融化后再度结冰导致的湿滑地面。 未来几天桑德贝将直接受北极涡旋中心控制，目前各大天气数值均支持桑德贝天空放晴后的20-21日清晨出现-30℃左右的低温，这将是今冬以来桑德贝的最低气温。 下图分别为桑德贝市区未来数天气温和阵风的数值预报集合。推荐使用windy.com查看未来一周内的天气变化情况，也可以让你更直观地认识掌管桑德贝天气的神——Alberta Clippers.
