It is usually quick, going from temperatures around 60 degrees and moderate to snowing. It is one of the more interestingly quick events, but certainly not the quickest.

Temperatures will begin to moderate on Sunday. By Wednesday of next week, we might even see a rain shower or two.

Farther west temperatures will be even higher. In St. Louis temperatures are expected to rise to 80 degrees tomorrow. They have a shot at the record, which is 81 degrees.

For instance, temperatures last week in the Northeast were 10 degrees warmer compared to the same period last year. That helped push sales of seasonal merchandise. Is all sales strength due to the weather? That's hard to say.

Temperatures will drop another five to 10 degrees over the next 24 hours. Winds will pick up and race through the Gorge. Gusts at the west end might reach 50 mph. Wind chill temperatures will drop to dangerous levels, -10 to -20 degree levels.

I would anticipate that we're going to have one-way flagging. There could be a moderate impact.
