The forecast highs today will struggle to get into the 70s across the High Plains today and in some cases we’ll be stuck in the low 60s across the far north.

Hello Winter

A fresh blanket of snow covered Pike’s Peak in Colorado this morning.  The top of the peak sits just above 14,000 feet and snow in September is pretty normal there. Are you ready for snowflakes?  Check out the responses on the WeatherNation Facebook wall. 

Chilly Nights

Overnight lows again tonight will be chilly enough to prompt some frost and freeze potential across the northwestern reaches of the nation.
