Mt. Hood Snow Forecast – 5000′
4a-8a 8a-12p 12p-4p 4p-8p 8p-4a

Good morning,

It’s raining out there in the Gorge this morning, which is much better than freezing rain and better even than snow. The rain should continue to fall heavily through 10am, and then taper off, at which point I can go play outside, because damnit, that’s what I want to do on my day off. It should also warm up to near 50 here today. It’s already warmer outside than I am years old, so it’s a good start to the day. Tomorrow also looks wet and rainy, and colder, with the bulk of the precip falling between 7am and 4pm. Thursday looks dry and cold, and with west wind in the Gorge, we’re likely to see at least some sun. Friday looks very cold, but not windy at all, so we’re more likely to see gloom in the lowlands.

As you all might have figured out, I’m obsessed with mountain biking. If you are too, remember that the trails are mudbogs right now and your tires will do damage, so if you ride, commit to some trail work days. However, with sub-freezing air returning, and very little, if any snowfall expected Thursday below 1000′, the trails should snap and become fast and fun. BTW, sorry, Parkdale and Odell, but you’re going to get more snow Wednesday mid-morning on.

Speaking of snowfall, it’s raining and sleeting on Mt. Hood right now, after a brief interlude of light snow last night. Very heavy rain/sleet mix will continue through 10am, for 1” water value by 10am and 1.1” by 4pm and trace amounts after that. The snow level will be 6500′ at 7am, rising to 7500′ by 10am and dropping just a bit to 7000′ by 4pm. With mostly clear sky overnight, the snow should snap hard into a big ice block by Wednesday morning. Wind today will be W 45 early, W 50 at 10am and W 55 at 4pm. That should be plenty of wind to affect lift operations.

Wednesday starts off horrid, with a sheet of ice on the ground, although groomed runs should be fun, soft, ground-up ice (aka sugar snow) with spots of blue ice. It will be cloudy first thing in the morning. Precip starts falling around 7am, and should fall as snow, with .8” WV by 4pm for 7-9” of new snow. After 4pm, precip ends and partly cloudy sky returns. The freezing level will be 6500′ at 4am, but don’t worry. It will drop to 4000′ by 7am when precip starts and 1000′ by 10am, falling to less than 500′ overnight. Wind Wednesday will be SW 50-60 early, dropping to SW 30 mid-morning and going to NW 20-30 in the afternoon.

Thursday looks clear and cold, with the potential for a few orographic flurries. The free air freezing level will be less than 500′, and the wind will be NW 25-30, becoming NNW 30 in the late afternoon.

Friday looks partly cloudy and cold, with the free air freezing level at the surface and NW wind at 20-30. Models are disagreeing over the weekend weather, so we’re going to wait and see.

Have an awesome day today!
