When we get cold arctic air masses, we usually have two chances for a good storm: when the air mass arrives, or when it leaves. We missed the shot when the air mass arrived, so now is our last chance as models show the cold air moving off. For a heads-up, when I say tonight and tomorrow in this forecast I'm talking about Monday, December 9 and Tuesday, December 10.

I was correct on the Thursday night Friday forecast that we would get snowfall. Portland got 1" in spots, but the official number for Portland was 1/2" of snow. But it quickly evaporated and blew around, so by the end of the day the snow was gone. Models are just recently agreeing on snow early THIS Monday evening continuing into Tuesday morning. Here are the highlights:
-No southern snow this time-precipitation stays northRead More >
Here I am presenting my stunning visual 7-day forecast, for those of you who prefer to just look at the forecast and leave, rather than reading detailed analysis.

This article written on December 2, 5:45 PM. So, this transition day is almost over and nothing has happened in the area of precipitation. We saw scattered showers this morning, but not many reaching the Portland metro area. The arctic air is taking its sweet time to come down, and we shouldn't be completely settled with the arctic air until Wednesday. The initial cold from the arctic air should arrive late tonight or tomorrow. We should be running out of showers by 8pm, and by tomorrow morning there will be no precipitation in sight. So, today was boring as far as snow, but it is the turning point for many exciting snow chances.

So, we know what is going to happen today. We will get heavy rain, and then in the afternoon-evening time frame, we will run out of moisture extremely rapidly. It also happens that at that time, the arctic air is settling in. What timing. We should get nothing but the stray flurry. Now onto the more interesting news: This weekend, we have a possible chance of snow. I will go over the factors in this weekend's snow below:
We are definitely cold enough for snow this weekend, with -12c and -13c 850 hPa tempsRead More >
So, models are solidifying, and it looks like we won't be getting much on Monday Night, but I'll briefly go over the highlights.
Monday Night and Tuesday: 0"-Dusting here on the valley floorRead More >
There is still some confusion between the models on the specifics of the storm, but I have generated a forecast that seems most likely. So we'll skip the weather talk and go straight to my forecast:
Sunday: Rain. High around 55.Read More >
Hello. Last time I had a long article, and it relayed my thoughts on snow. Basically, my opinion was that the most we could get Monday Night or Tuesday Morning was a dusting or a wet rain/snow mix. I also said that I was going to create another article if something changed. Now I can be even more confident in the model runs, so I will give my new thoughts.
New runs are out, and now I will give some new thoughts.Read More >
You may have heard about snow, or chances of it. But, you probably do not know the specifics and just saw a snowflake in the forecast. Here I will explain the chances of snow, and why we might or might not have it, and at the end, one interesting sneak peek at snow chances after Monday night and Tuesday.
I will start from the beginning of this excitement. On Monday and Monday night, models were showing -10c to -15c at around 5,000 feet on the coming Monday night and Tuesday. This would mean a pretty good arctic blast setup down here, definitely cold enough for snow. Models were also showing a substantial wave of precipitation, which would mean plenty of snow.Read More >
