WHAT TO EXPECT:
You’ll have one more decent day to get ready, and that’s today. You can expect readings to top out around 44-47 throughout the Metro, with periods of clouds and sunshine. As you start to climb into the high country, readings will wind up 7-10 degrees cooler, so 34-39 depending on where you are. Winds will vary early, then turn southerly 6-12 MPH, higher near the foothills. Tonight, a rain/snow mix will drop some limited precipitation over the Metro and Jeffco, with minimal accumulation of snow expected except on cars and grassy surfaces. Readings will dip to 28-34 overnight with increasing clouds.
Friday morning will see perhaps a couple of peeks of sunshine early, then skies turning mainly cloudy as we get toward lunch and into the afternoon hours. Snow is expected to start falling between 2 and 6 PM depending where you are. Right now it looks like the earlier event kick off will be closer in to the foothills, say from a line between Boulder and Golden and Morrison, spreading from there. The heaviest snows will be overnight Friday night into Saturday, with snowfall rates approaching an inch per hour at times, and winds increasing to 20-30 MPH at times will lead to near white-out conditions.
As we get closer to the event, we’ll bring you forecast model maps and additional forecast details. Get your errands done today or tomorrow morning, and be ready to stay in and relax this weekend. Metro forecast snowfall amounts are 15 to 30 inches, with the higher amounts in the west suburbs and foothills, and amounts upwards of three feet or better for the Boulder valley and headed north toward the Colorado/Wyoming border.
