As of 5 p.m. Wednesday, Vancouver’s high temperature reached 60 degrees, the coolest since May 30. Rainfall was impressive as forecast with 1.50 inches. That brings our monthly total to 2.50 inches, way above average. What a mood change in the weather.

Heavy snow fell on Mount Hood, with 2 feet on the upper slopes. Impressive for mid-September. And technically, we are still in the summer mode until Friday. Skies will clear today, but with a chance of a shower or two. Tonight, with clear skies and plenty of moisture, we may see some foggy areas and lows well into the 40s and 30s in outlying regions.

The good news is, we had enough rain to just about put out the wildfires and add a fresh flow of water in the streams. High pressure builds Friday and into the weekend with warming temperatures lasting into next week. We may not see any measurable rain for the rest of the month.

While locally we had clouds, cool temperatures and heavy rain showers (add in a clap of thunder) Wednesday, the Washington Coast enjoyed blue skies and sunshine and a high temperature warmer than Vancouver’s. That occurs often with cold air aloft. The main band of rain moves inland and skies clear at the coast, but as the cold air moves inland and rises a bit, the towering cumulus clouds build and dump on us.

As the main front moved south across the Columbia, we had terrific showers around 1:30 p.m. with some street flooding and reduced visibility.

I said the other day that we could see cooler, wetter weather this winter with a La Ni?a pattern shaping up. On the other hand, the collection of woolly bear caterpillars I’ve seen would tend to indicate a mild winter. More on that later.
