Arctic Blast Arrives Tonight

Well, we've gotten through the snow but now Mother Nature hits us with quite the chill this week.

Currently, a high pressure system is building just south of the Gulf of Alaska, creating a large ridge of high pressure over western Canada and Alaska.  Strong winds within the jet stream will push cold air south over the next several days, causing temperatures in the lower 48 to plummet.

Highs will only make it near 10° Tuesday and Wednesday, then drop into the single digits for highs on Thursday. This could even be record breaking cold for Thursday. Daytime chills will be stuck below zero, and even down to double digits below zero for Thursday afternoon. That's just daytime chills!  Overnight lows Wednesday night through Thursday night will drop below zero. When we factor in wind chills, it could feel like -20 to -30°! This would be Wind Chill Advisory criteria.

There will be a brief 'warm up' Friday and Saturday afternoon ahead of a strong low pressure system that looks to bring another round of accumulating snow.
