Weather Eye: After that 90s flashback, back to autumnlike conditions

Friday’s high of 94 degrees brought memories of the long hot summer we’ve endured. Saturday was slightly cooler but still in the 88- to 90-degree range in most neighborhoods. Today, we begin a transition back to the recent autumnlike weather.

Monday through Thursday, it appears, unsettled weather will be upon us with showers, cooler temperatures and maybe a soaking rain on Wednesday. That would be the remnants of Typhoon Kilo.

The cyclone, once a Category 4 typhoon, held together for three weeks, which is quite rare. It was the third tropical cyclone to cross the International Dateline this year, marking the most since 1997.

Clouds and rain will drop down from the British Columbia coastline and may lower snow levels once again to the Cascade peaks. Factor that in if you go up in the mountains — it will be damp and cool.

So, how will our last weekend of summer fare? Computer forecast models Saturday afternoon were looking favorable with sunny and warm weather. Alas, that is a ways off, and with another stubborn trough of low pressure to our west, that may change.

September so far is a month with extremes. We had highs of 60 degrees on Sept. 6 and 94 degrees on Sept. 11. The average mean temperature is 64.2 degrees, 2.2 degrees below average. Rainfall is only 0.36 inch, about a tenth of an inch below average.

Our coolest temperature so far is 47 degrees on Sept. 3. These statistics are at Pearson Field, where the official Vancouver weather observations are taken.
