Temperatures will quickly crash Thursday night ahead of a dynamic storm system on Friday. With many moving parts, it is still too early to predict snowfall. What we are certain of, however, is dangerously cold wind chills through the weekend. Stay tuned as this forecast continues to evolve.
With gusty winds and extreme cold, hypothermia becomes exponentially more likely. Apparent temperatures will dive well below zero on Friday, so be sure to dress warmly and limit time outside.
