Went from 47* Sat during the day...to -12* by Sun sunrise with about 6'' of snow. Been bitter cold here until yesterday afternoon when it finally hit 34*.... M-W average daytime hi's were 15* dropping to -20* after sunset.
And the weather gurus are predicting another "artic blast" to hit this weekend with the temps staying in the low teens and way below zero at night, staying around for most of next week.

Now I remember why I grew to loathe Colorado winters. For me ideal temps would be 70's/80's all year round with it only getting cold and snowing during the Holidays....
