plains through tonight. This will bring snow to the northern
Colorado mountains. Some snow will also be spreading onto the
plains Thursday, with 4 to 7 inches near the Wyoming and Nebraska
borders. The snow will taper off late tonight into Friday
morning. The snowfall will lead to winter driving conditions over
the northern Colorado passes with slick roads.

70 overnight were generally in the 1 to 4 inch range, though
there was heavier snow in the higher mountains of Larimer county
with up to 9 inches of snow there.
