From Summer to Winter Along the Front Rain of the Rockies this Weekend

In most places with warm summers and cold winters, a months long autumn separates the summer from the winter. The front range of the Rocky Mountains are about to go through a drastic seasonal transition this weekend into early next thanks to a strong push of unseasonable cold air from Canada.

Summer will be in full swing along the front range from Montana to Colorado this weekend with sunny skies and high temperatures in the 90’s, which is about 20 degrees above normal. But a strong storm system diving in from the Pacific Northwest will drag much colder air in beginning in Montana Sunday night, then down to Colorado by Monday night. Temperatures are expected to fall back into the 20’s at night, which is about 20 degrees below normal. The result will be a huge swing in temperatures over a matter of hours in many locations.

The strong low pressure system responsible for the cold air will also bring the potential for significant snowfall in the mountains. There are even indications that accumulating snow will fall in lower elevations along the front range, in cities like Denver and Boulder.

This could be the earliest accumulating snowfall that some areas along the front range have seen in decades with the possibility that the higher elevations may get over a foot of new snow. Any accumulation will also bring the threat of downed trees as winds are expected to be gusty with this storm system. This is certainly going to make for an interesting and potentially historic Labor Day weekend along the front range of the Rockies.
