Winter Storm Warning: Complex System Brings Snow, Ice, and Dangerous Cold to the State: A potent winter storm is set to impact the state beginning Friday morning, bringing a complex mix of snow, sleet, freezing rain, and dangerously low wind chills.
State Climatologist Gary McManus issued an update highlighting the volatility of the incoming system, specifically noting a “troubling intrusion of warm air” in the mid-levels of the atmosphere. This “warm nose” of air threatens to melt falling snow before it reaches the ground, potentially transitioning what could be heavy snowfall into a mix of sleet and freezing rain.
“How thick will that warm nose of air be, and how far north will it push?” McManus wrote. “That’ll make all the difference in whether you get 8 inches of snow, for example, or 3 inches of snow and a whole lot of sleet. Or freezing rain.”
Timing and Alerts A Winter Storm Warning has been issued for most of the state, effective from 6:00 a.m. Friday through noon Sunday.
While surface temperatures are expected to be “really cold” heading into the weekend, the forecast remains fluid regarding precipitation types. McManus cautioned that the storm is still developing and is liable to change as it crosses the Rockies.
“The acute answers to those questions just aren’t available yet,” McManus stated regarding specific ice totals and travel viability. “So you gotta be weather aware over the next 72 hours. You should have all your preparations for an impactful winter storm completed by tonight.”
Extreme Cold and Travel Hazards Beyond the precipitation, the storm brings a threat of life-threatening cold. An Extreme Cold Watch is in effect from Friday through Monday morning, with wind chills expected to drop as low as -20°F.
McManus warned that travel could be perilous, noting that “if the snow and ice… park [you] in the ditch and you have to get out, then the frigid air will get ya.”
Residents should not expect a quick thaw. The fresh snow pack is expected to increase surface reflectivity (albedo), reflecting sunlight and keeping temperatures low even after the storm passes. “There won’t be a lot of thawing going on, at least until the sun comes out,” McManus noted. “These types of winter storms help create their own environment for days after it’s over.”
A Silver Lining Despite the disruption, the system promises significant precipitation for the drought-weary region. Forecasts indicate the best liquid-equivalent moisture totals for the state since November.
Residents are urged to stay tuned to local media and National Weather Service outlets, as the forecast “can and probably will change” over the next 24 hours.
The Cattle Comfort Index is getting close to the Cold Danger category. This is for Friday but Saturday and Sunday will be worse. Extra appreciation for those livestock industry workers about to battle these conditions
