Weather Eye: Fall’s beginning brought dramatic end to summer

Just 12 days ago, I was writing about the hot weather over us and how many 90-degree days we have logged this summer. Then on the first day of fall, the curtain abruptly lowered on summer. What a dramatic change.

Skies were slow to clear Saturday, but afternoon sun breaks peeked through the thick low-level stratus clouds. Today we may see our first foggy morning of the autumn. I mentioned our progressive weather pattern — some rain and then some sun — the other day. That still looks like the case.

Another weather system should drop over us from the Gulf of Alaska on Monday, for rain and then showers Tuesday. This has a colder air mass associated with it, so some light snow is possible down to 6,000 feet in the Cascades. As skies clear later in the week, some outlying colder areas could have their first frost. Not so here in the city, but it will be a chilly morning.

How are we doing this month? Statistics for Vancouver show the average mean temperature is running 67.2 degrees, about three degrees above average. Of course, those hot days really helped that. Rainfall so far is 0.88 inch, 0.44 inch below average. I expect the storm bringing us some showers the last two days of the month will not be enough to bring us to normal or above in the rainfall department.

Looking way ahead to the week of Oct. 6, some computer models bring a cold air mass from the Yukon down over the Pacific Northwest. Others take it the usual course east of the Rockies. If it did reach us, snow would bring a first taste of winter to low levels here as well as east of the mountains. At this point, it is just a speck in the eye, probably not worth a second thought. But then again …
