It still appears that the storm system moving through Colorado Sunday and Monday will not be a major snow maker.
Some mountain snow and valley rain will become more likely in western Colorado on Sunday while it stays mainly dry along the Front Range and eastern plains, including southeastern Wyoming. Then, the likelihood for mountain snow and low elevation rain-changing-snow increases for the Front Range, eastern Colorado, and southeastern Wyoming Sunday night and Monday.
There is a good chance for several inches of snow in the mountains including Nederland, Brainard Lake, and Idaho Springs. In fact there could be around 6 inches if the storm doesn’t move quite as fast as some numerical models are suggesting, but those higher amounts are more likely near and west of the continental divide.
For the lower foothills and adjacent plains along the Front Range, rain is likely to change to snow, but accumulation may be limited to mainly light accumulation on cars and grassy areas. If the changeover occurs before sunrise Monday (which it might, especially the northern Front Range), there is a better chance for accumulation. Snowfall during the day will be competing with high melting rates.
Don’t forget to turn your clocks back tonight!
