Winter's First Punch
Following a mild October along the Colorado Front Range, the first significant cold front of the season pushed across the Rockies yesterday morning and, throughout the day, dropped the temperature in Metro Denver from the low 50s (F) to the upper thirties. Up to a foot of snow fell in the higher ranges of the State's northern and central mountains while the mountain valleys received a few inches. A chilly drizzle developed in Denver yesterday afternoon and some of the higher suburbs received a light dusting of snow.
Overnight, Metro Area temperatures fell into the upper twenties, a taste of many mornings to come. Fortunately, the region's high elevation, intense sunshine and downsloping "chinook" winds, generally limit the duration of winter weather outbreaks. Indeed, the coldest average afternoon highs, which occur in mid-late January, are in the low forties (though overnight lows often fall into the single digits or below zero).
Throughout the thirty two years that we have lived in Colorado, the week of Halloween has often brought the first significant snowfall in Metro Denver; on the other hand, September snow is far from rare. This week, however, a rapid warm-up is forecast, pushing afternoon temperatures into the sixties and lower seventies. There will be no need for bulky coats under those costumes!
