Weather Eye: November snow? It’s looking likely

By Patrick Timm

Regardless of whatever happens today weather-wise, at least most folks were prepared for the worst. Roads were de-iced, snow plows put on standby, schools running two hours late, etc. Last-minute food essentials purchased. Winter storm watches or warnings were issued.

Now what will happen? You will for sure already know the answer when you read this Thursday morning. Unfortunately, on my part, writing this column late Wednesday afternoon before another set of forecast models come out, I will have to rely on my gut feeling.

We do have a modified arctic air mass set in place. We have moisture coming up from the south poised to override the cold dome of air. Temperatures are not all that cold like they would have been a month from now. Remember, snow is rare in November. I have only seen a snow cover in November three times in my lifetime. Will I make it to four?

Read on.

Temperatures, especially in the wind-sheltered areas, will likely have dropped below freezing Wednesday night before the skies turned overcast. I also expect we will see moisture falling from the skies by this morning. However, much of it will evaporate due to the very dry air mass and persistent east winds. If — and this is a big if — enough moisture moves over us, it will chill the air several thousand feet above us and bring snow or snow mixed with sleet all the way to the ground. I think this is the most likely option as of this writing and expect at least a trace to three inches (worst case, it snows all day).

Even with this weak but moisture-laden weather system invading our space, I don’t believe the cold air is going away until next week. We may rise above freezing, but as the air drops southward again, we cool off with more cold air coming down the Columbia River Gorge. This time, quite a bit of snow will be coating the narrow gap keeping us chilly.

I wish I could have waited until later computer forecast models come out to finish this writing but deadlines are deadlines. Bottom line: I do expect to log in number four in my lifetime tally.
