Blowing snow was an issue earlier this morning with gusts over 70 MPH knocking out power to parts of south Boulder. Winds have retreated back up into the higher terrain already, but we can see fresh snow blowing off the high peaks in Rocky Mountain National Park still #COWX

Near-surface upslope will crank up briefly overnight (graphic i is the forecast for 11PM at 800mb level). Should see snow rates pick up and in and near the lower Foothills as a result. Just not a lot of moisture to work with out there or additional lift. Snow will be fluffy though! #COwx
