With most regions now having at least a light covering of snow, it’s definitely starting to look like winter. Combine the snow cover with a couple of shots of arctic air and this forecast period is going to start feeling like winter too!
The area of low pressure expected to help bring mild weather to our region this week ended up being much weaker, thanks to last weekend’s low being stronger than expected. As a result, we only saw a slight warm-up early in the week before arctic air pushed in behind the low by mid-week. A weak area of low pressure is forecast to slide southeastward behind this first push of arctic air late Thursday and through the day on Friday. This system will bring some clouds and maybe a few flurries, but doesn’t look like it will bring any measurable snow.
A second arctic high will push south behind this low over the weekend, bringing sunny skies and cool temperatures. By Sunday the high will be to our southeast, which will allow the winds to become southerly. This will start to bring in milder air, especially over western regions. This warm-up will only last a day or two as an area of low pressure sliding by to our northeast will drop a cold front through the region by next Tuesday. Behind this front we’ll see another arctic high build in, dropping temperatures back down to the bottom end of the usual temperature range for this time of the year.
Looking further ahead, the weather models show a slow warming trend for later next week as the arctic high slides to our southeast, but once again, it doesn’t look like the mild air will stick around as another area of arctic high pressure looks ready to drop southward by the end of next week.
Usual temperature range for this period: Highs, -10 to 2 C; lows, -21 to -6 C.
