Forget fall - we're straight on to winter in parts of the Plains on this mid-October weekend. Places like Denver, Colorado and Minneapolis, Minnesota saw snow on Sunday morning. For Minneapolis, it was their first accumulating snowfall of the season - they officially measured 0.3" at Minneapolis-St. Paul International Airport as of midday on Sunday afternoon. For Minneapolis, the measurable snow is well ahead of schedule. The Twin Cities usually see their first measurable snow in early November, putting this snow well before their norm. Denver saw a half inch of snow on October 6th, and there wasn't an official total for the Mile High City as of mid-afternoon on Sunday, but areas near Denver received several inches of snowfall. The snow in both Denver and Minneapolis had all but stopped as of Sunday afternoon, but enough fell to paint a wintry scene in both places. Denver's average first snowfall is on October 18th, and now the city's seen two snows before its typical first average snow. A deep trough of low pressure has kept the western and northern third of the country locked in a much chillier than usual weather weather pattern, but warmer, or should we say, more seasonable weather is on its way in both spots.  Stay with WeatherNation for the latest on the wintry fall weather.
