Good morning!

If you would like to hit the Columbia for some windsurfing or kiting this morning, you have your chance. The gradient is at east .23, enough for 30+ at Stevenson and 40+ for Rooster. Easterlies slowly fade through tomorrow, switching to west winds on Sunday morning. It’s a balmy 40 degrees in Stevenson this morning, so you should be plenty warm. Enjoy.

Because of the east winds, it’s going to stay near freezing in the Gorge for the next 48 hours. Expect a mix of snow, sleet and freezing rain, At the most, we’ll see 2-3” of snow in the Gorge. At the worst, we’ll see a nice coating of ice. Yes, I know it’s 35 degrees this morning, but there’s a good chance evaporative cooling will drop the temp a couple of degrees, so I still think snow is likely.

This morning looks dry on the mountain until about 10am when light precipitation should move in. Light precip will continue to fall until tomorrow morning around 10am. I think we’ll see snow at first, but the inverted temperatures this morning are a big concern for freezing rain, sleet, and/or rain. Rain showers, at least at HRM base, and possibly to the top of Mt. Hood Express, are likely. Total water value between now and Saturday morning will be .25-.4”, for a total of 2-4” of snow at higher elevations. Light SSW wind this morning builds to SSW 20-30 by 1pm.

Tomorrow starts of with the snow level around 6000’, rising to 7000’ during the day and then falling during the evening. Light precip before 9am gives way to a dry, cloudy day. Precip returns around 7pm, mostly likely in the form of snow, with the snow level around 5000’. Winds on the slopes tomorrow will be 15-25mph early, building to 30-40mph by midday.

The snow level on Sunday starts off around 5000 feet, falling to 3000 feet during the day. We’ll see 2-3” of snow Saturday night into Sunday morning, and then 4-6” between 7am and 4pm. Winds start off at SSW 25-30mph Sunday morning, fading to WSW 15-25mph and then building to WSW 25-30 Sunday evening.

Snow falls pretty much all night Sunday and all day Monday, with snow levels at 3000 feet or so, for a nice powder day on Monday. Winds will be W 15-25mph.

The jet stream takes aim at the PNW through the middle of next week, for more snow every day.

Have an awesome day today!
