The Next 24 Hours: Waking up to temperatures in the teens and 20s for some and wind chills falling into the -40s to -50s in some places. Wind chills at this level can quickly become dangerous. They can cause frost bite within 10 minutes so exposed skin should be covered. The west wind will pick up a little bit after sunrise. We will still have clear skies. By lunchtime, the westerly wind will have picked up in many locations and shifted to be out of the southwest.
