DENVER -- Temperatures plummeted way below zero in Colorado Wednesday and they weren't expected to be any warmer overnight into Thursday morning.
School districts started closing or announcing delayed start times Thursday as a result of the dangerous cold. Douglas County Schools was among the districts that announced a 90-minute delayed start.
The National Weather Service issued a Wind Chill Advisory for metro Denver, the Front Range and eastern plains of Colorado. It's in effect from 7 p.m. Wednesday until 11 a.m. Thursday.
Wind chills were expected to fall to 18 to 25 degrees below zero. Light winds combined with very cold air will create those dangerous wind chill readings. The wind chills can cause frostbite and lead to hypothermia in 30 minutes if precautions aren't taken.
The actual low temperature in metro Denver could plunge to 10 to 15 degrees below zero.
If y0u must go outside in the cold, make sure you wear several layers of clothing, a hat and gloves.
Temperatures Thursday in metro Denver are expected to be in the single digits and teens.
"There will be another round of light snow showers possible," says Chief Meteorologist Dave Fraser. "We could also see a few flurries on Friday, but temperatures improve with high readings in the 20s. A few inches of snow is possible on Saturday with our next passing storm system."
