In a video titled “AM Mountain Weather Update 12/6,” Chris Tomer, a Colorado meteorologist, provides a seven-day forecast focusing on mountain weather. He highlights two key weather events: the Pacific Northwest flow and an East Coast storm. The Pacific Northwest flow, occurring around December 7-8, is expected to bring moderate snow to Colorado, Utah, and Wyoming. The East Coast storm, forecasted for around December 10, is predicted to bring widespread snow across the East Coast.
Tomer explains the role of the jet pattern in these weather events, noting that the dip in the jet stream over Wyoming and Colorado will lead to heavier snow accumulation, while conditions over the Ohio Valley, including wind and warm air, will fuel the East Coast storm.
He also discusses the impact of these events on the Northeast, particularly the snow conditions resulting from a cold front. Tomer emphasizes the significance of the rich Pacific Northwest flow impacting Idaho, Wyoming, Montana, Utah, and Colorado from December 7 to 8, and a larger Eastern storm system expected from December 10 to 11, starting with rain in Vermont, New Hampshire, and Maine. Tomer advises viewers to stay safe and be prepared for these conditions.
