What’s that Falling from the Sky?

posted in: Weather Discussions | 0

This may very well be the question in Nederland Wednesday night and Thursday as a round of light, accumulating snow is expected across the mountains and foothills of northern Colorado. Chicken little thought the sky was falling.  After our prolonged spell of predominantly warm and dry weather, it may come as a shock to some that it can actually snow here.

Ok, all sarcasm aside, a cold front will push southward across Colorado during Wednesday, passing through Nederland and the nearby Front Range Foothills communities around 11 AM. Behind this front weak north to northeasterly upslope winds will develop and clouds will thicken as the cold moist air is lifted up and over the Continental Divide.  There will not be alot of moisture in the atmosphere and the upslope flow will be marginal.  However, there will be some additional upward lift in the mid and upper levels of the atmosphere as a jet streak dives to our west, positioning us in the favorable left exit regional of the core of fast moving winds. All of these factors combined should result in a period of steady light snow Wednesday night into Thursday.  Accumulations around Ned will likely range from 1 to 3 inches by Thursday morning, just enough to make the roads a bit slick and make it look a little bit more like Christmas. Temperatures on Thursday will struggle to get out of the 20s with lows in the mid teens. Brrrr. It will feel cold, but that is really just about normal for this time of year.  We have been spoiled.

Stay tuned. Sometimes these weak, fast-moving storms which blow in from the northwest can pack a bit more snow than expected, especially if snow to liquid ratios are higher than expected.
