Weather Eye Saturday may have been 2017s last day to hit 70

first_img Chalk up yet another gorgeous day Saturday with clear, sunny skies and 70-degree weather! We have had eight days at 70 degrees or higher this month, and I believe Saturday was our last day of reaching 70. With cooler weather and the new month of November settling in mid-week, the odds do not favor highs in the 70s.Much cooler weather (back to normal) will be in store the next few days, and then later in the week we get back to some cool showers and snow in the mountains. Unsettled weather will be in the forecast for some time.You may have seen or heard, via smartphone weather apps or even in a large Portland newspaper, of possible snow in the Vancouver-Portland area. Not so, I say. The reason is that forecasters have several computer forecast models developed by the United States, Canada, Europe and others, and they show trends in the air flow coming our way. Just like a plate of spaghetti noodles with different lengths of noodles, there are many various trends within the model we call ensembles. And they can be all over the place. The hi-tech phone apps use these models and often pick extremes in the ensembles.Most apps that showed snow for us Friday disappeared by Saturday morning and now show just a cold rain. I see some had highs of 44 degrees, which is too cold yet for us here in the lowlands. Most likely in the low 50s. The good news out of this is, with a northwest flow of air the next seven to 10 days, we will get snow in the mountains even down to low elevations such as Government Camp. Winter arriving early? Ski season beginning on Thanksgiving? Maybe.OK, for your Tuesday Halloween we will have clear skies and sunshine, gusty east winds particularly east of I-205 but dying down in the evening hours. It will be in the low 60s for highs. So, a dry, crisp evening great for the little ones. No plan B needed this year. And a bonus, we still have daylight saving time stretching the daylight a wee bit for the start of trick-or-treating.Patrick Timm is a local weather specialist.
