 ...WINTER WEATHER ADVISORY FOR THE MOUNTAINS ABOVE 9000 FEET THIS EVENING THROUGH THURSDAY NIGHT... ...HIGH WIND WATCH EASTERN PLAINS LATE THURSDAY AFTERNOON THROUGH FRIDAY MORNING...  This hazardous weather outlook is for northeast and north central Colorado.  .DAY ONE...Today and Tonight  One last mild day can be expected across the plains. The weather will begin to change today, however, as a storm system approaches from the northwest. Scattered showers and isolated thunderstorms will develop over the mountains through mid afternoon, and then spread east/northeast across the plains through late afternoon and evening. Most will produce light rain and gusty winds up to 35 mph.  Showers will become more widespread in the high country, and snow levels will lower from about 10,000 feet this afternoon to mountain valley floors overnight. A few inches of snow will accumulate over the higher mountain passes with slick travel conditions developing overnight. Most roads in mountain valley locations will likely remain mostly wet, or perhaps slushy at times should heavier snow showers occur.  .DAYS TWO THROUGH SEVEN...Thursday through Tuesday  Mountain snow will increase in intensity on Thursday, when impacts to roadways will be most likely. The heaviest snow is expected in our northern mountains, namely the Park Range and Rocky Mountain National Park, and including routes such as US-34, US-40, and CO-14. Snow will be lighter across the I-70 corridor, although slick conditions will still be possible there. On the plains, rain showers are likely Thursday, then rain will decrease from west to east Thursday night. There may be a dusting of snow Thursday night in Douglas and Elbert counties above 6000 feet and along the northern Colorado border, with minimal travel impacts.  Strong winds with gusts up to 60 mph are also expected on the plains and over the highest elevations of the Front Range mountains on Thursday, decreasing from west to east Thursday night and Friday. A High Wind Watch is in effect for the eastern plains Thursday afternoon through Friday morning.  Patchy below-freezing temperatures are possible by late Thursday night, with a more widespread freeze Friday night over most of northeast Colorado.  .SPOTTER INFORMATION STATEMENT...
