  • In northern Colorado, snow is expected to resume later this morning, becoming heavy at times beginning this afternoon. Snow will continue in these areas through tonight before mixing with or changing to rain by Saturday morning.
  • In northeastern New Mexico, scattered snow showers are expected to continue across the greater Santa Fe Metro this morning and afternoon before ending early this evening. 

Potential Disruptions & Recovery Weather:

  • In central & southern Colorado, light to moderate snow is ongoing this morning which will become heavy at times throughout the day with the greatest impacts to travel expected late this morning through late this evening.
  • In northern Colorado, snow will resume this morning with the greatest impacts to travel expected this afternoon through tonight with conditions improving Saturday morning as the precipitation changes to plain rain.
  • Visibility may fall below 1/2 mile at times with snowfall rates as high as 1-2 inches per hour.
  • In northeastern New Mexico, wind gusts of up to 35 mph will combine with the heavy snow this morning which will result in near-blizzard to blizzard conditions at times through this afternoon.   
  • Where heavy snow results in depths approaching and/or exceeding 20 inches, roof loading will become an issue on uncleared flat roof buildings.
  • Across the impacted region, high temperatures into the mid-30s F to lower 40s F today and Saturday will rise into the mid-40s to mid-50s F on Sunday and Monday which will aid with the melting of accumulated snowfall on roadways.
  • However, melted snowfall may refreeze in the overnight to early morning hours each day Saturday through Monday, resulting in patchy black ice formation on roads with the worst travel conditions on secondary roads.
