Weather Eye: Cold trough will be good news for ski areas

We finally warmed into the 50s with the sunny skies Monday. That after a miserable three days of persistent inversion with highs barely cracking the 40-degree mark. Above 1,200 feet or so it was sunny all weekend.

I’ll mark that up to experience as I thought we would have at least some sunshine. Gads, I have to tell myself forecasting weather is certainly not an exact science at times. It looks dry through the last couple days of the month. So far Vancouver has received 2.83 inches of rainfall and if nothing hits the rain bucket by midnight Thursday, we will end up nearly 3 inches below average for the month.

The inversion caused warm temperatures up in the Cascades too, with highs in the 50s and some locations into the 60s. Lots of snow compaction and melting flowing off the mountains. The good news is the big change in the weather pattern. Read on.

By Friday a cold trough of low pressure drops down from the Gulf of Alaska and lowers snow levels well below the passes. Maybe down to the upper foothills to our east. The ski areas will pick up a good shot of fresh powder, so this is great news.

For us it will be a cold rain, with highs only in the 40s. I don’t see any possibility right now but if enough cold air mixes in we could see wet snowflakes here and there in the lowlands. Don’t start passing that rumor quite yet! Check back right here on Thursday.

Meanwhile, the polar vortex has put much of the country in a deep freeze. It is a large area of low pressure and bitter cold air that surrounds Earth’s poles. Please remember, the term is nothing new but in the news headlines right now big time. It has a counterclockwise flow of air that generally keeps to cold air near the poles. In the winter it expands and gets caught up in the jet stream and gives the United States (and other countries) the arctic outbreak of cold air. This year it is particularly cold.
