We have little change overall to the going forecast. Rain is expected to change to snow overnight Saturday into early Sunday morning in Denver, with a Winter Storm Watch in effect from late tonight through Sunday evening for the metro area and Front Range. The watch could very likely be upgraded to a Winter Weather Advisory later this afternoon.
Snow totals will vary greatly depending on your locale. Higher elevations to the south and west of Denver will once again be favored for highest snowfall totals, with lesser totals across the northern suburbs of Denver. We continue to stick with slightly lower snow totals for Denver proper, with much of the accumulating snowfall being confined to grassy and raised surfaces. Models are very moist with this system, but the big question is how much melting will take place with warm surface temperatures and high sun angle Sunday. We've updated the snowfall map above with our latest thinking, and will continue to refine as needed.
With recent leafing, where snow accumulates, this could be a high impact event for your trees. The weight of this very wet, heavy snow will be a tremendous burden on them. Go out and gently shake the snow off trees if they start to look like the weight is taking a toll. We expect snow to be heavy at times, which will make travel difficult Sunday and Sunday night, with blowing snow causing reduced visibility.
In Denver roads will likely stay mostly just wet until after dark on Sunday. Where snow continues Sunday night expect some ice and slush to accumulate on roads, especially secondary ones. Be mindful that overpasses will become snow-packed before the warmer road surfaces. We have the potential to challenge our all time record low temp for the date which is 15 degrees with a couple of the models bring us into the teens by early Monday morning.
We'll continue to monitor all the latest here at Weather5280, and push updates as necessary as we head into the overnight hours Saturday and during the day Sunday. We'll be active on Twitter and likely the Live Blog throughout this event.
