Get ready folks. A blast of truly cold arctic air is destined to plunge southward soon. We’ve had some small tastes of cold temperatures this winter, but the pattern evolving for later next week (from about the 14th through at least the 17th) could bring the coldest air we’ve felt here in a long time.
The jet stream will pull progressively colder blocks of air southward, with moderately cold air at first, culminating quickly to very cold air around Jan. 16th. Our lack of snow cover will prevent temperatures from tumbling as far as they potentially could otherwise.
