They also generally agree that tomorrow will be a soaking wet day, yep, steady rain the whole day from Salem northward west of the Cascade crest. Models are in good agreement that steady rain returns late tonight as the pineapple express/atmospheric river moves back south into Oregon and southern Washington. But we are in the 3rd day of a Flood Watch in our region, so there’s only one forecast question that matters the next 2 days…will there be enough rain to cause flooding? There is no strong wind, snow, or ice in the forecast. Those are the events that cause flooding/damage. We only really care about the pink or black lines on this chart that includes all of last year.

More rain falls on what’s left of that snowpack through Wednesday morning. The warmth is caused by the “Pineapple Express” that is centered just offshore copious amounts of rain are being dumped to our north this evening since it is aimed at BC and Washington right now. This has given rivers and creeks a chance to go back down and a decent day in the lowlands. Unfortunately, rain continues to fall on fresh snow in the Cascades and it’s melting quickly. You can see the warmest December days on records going back to 1940 Salem was just 5 degrees from their 68 degree record. It tied the all-time December record of 65 degrees.

Portland’s weather roller coaster could be an example of how the climate crisis can produce both hot and cold extremes – a form of “weather whiplash” that scientists say is becoming more common.We don’t often get short-sleeve weather in December but it happened today! Hundreds of heat-related hospitalizations and deaths were reported during that heat wave, leading officials to call it a mass-casualty event.
