Several potentially major winter storms are forecast to impact the region through the end of November, beginning on Sunday. Long-range models indicate a Thanksgiving storm, but it’s too early to worry about it, as it’s still two weeks away.
Depending on which model you choose to root for, 1 1/2 to 6 feet ( not a typo) of snow will be possible across the mountains, with lesser amounts in the lower elevations, of course, by Friday night!
Long-time followers know I am reluctant to share model data this far in advance; however, due to the potential of these storms and the fact that they will be the first of the season, I feel it is important enough to disseminate the information.
Don’t skip over this point; models often change before the events arrive. That being said, when they all start converging on similar ideas, forecasters need to start paying attention.
Those were some big numbers I was citing, and I know some of you are dying to see the maps yourselves.
I will stick with liquid precipitation outputs for now. If the models are correct, Sunday’s event will be the weakest of the bunch. However, the US and Canadian models are showing the “perfect” storm track for the mid-week and late-week storms.
I also won’t be adding the D and T to the maps until we get closer to the events. I expect accumulating snow in the lower elevations if the mid- and late-week storms materialize as the models predict.
Here we go, the liquid precipitation forecasts in inches, through Friday night, November 21st. At or above 9,000 feet, multiply the liquid totals by 11 (for now) to convert to snowfall equivalent.
European
GFS (US model)
Canadian model comes in strong!
Some of those light brown shades indicate 7 inches of liquid!
What now? Don’t take it to the bank yet, but be aware of what could happen and stay informed. Does anyone have any recommendations for long-lasting AC generators? I am seriously considering buying one to maintain my internet access during the winter storms this season.
Consider a Honda Generator. I’ve had the 2200 model for over 10 years and it always starts and runs very quietly.
