I used to live in Fairbanks, Alaska, and can remember temps getting down to about -40 for days on end. But Alaska doesn't even make the Top 5 list of coldest places on the planet.
The National Weather Service has issued a Winter Storm Warning for northern Colorado. The warning begins tonight at 6pm (Tuesday, December 3, 2013) and will remain in effect until 6pm Wednesday night (December 4, 2013)
After what has been a nice stretch of extended summer weather, Mother Nature will be reminding Northern Coloradoans this weekend that it is indeed Fall on the calendar. Cold rain is likely on Saturday with highs struggling to reach 50. Showers will be possible again on Sunday with continued cool temps.
