I put about an hour a day into creating a (hopefully) accurate forecast, and I pay for the hosting on this website. If you find this service valuable (gets you the good days on the mountain, saves you gas and time, etc.) please donate. I’m just one gal with other jobs writing this for you! Your generosity keeps this going for everyone. I also send an email version of this forecast. Make a $12 or larger donation, and you’re on the email list for a year. No dealing with the twice-yearly pledge drive. You’ll also have a chance to win prizes from the sponsors, when I have prizes to give. Thank you again for your support!


Mt. Hood Snow Forecast – 5000′

It’s Sunday, the day before the day before Christmas, and hopefully you have all your shopping done!

Gorge weather looks a little showery today, but not too bad. Tomorrow looks dry, but models suggest we’ll have an inversion layer, or at best, a broken inversion layer. The models still suggest a bad day for drivers on Tuesday, with very, very strong east gradients pulling cold air through the Gorge (go ahead and windsurf or kite, if you like doing it in 31-33 degree weather). With cold air at the surface and 1” of moisture headed this way, 4-6” of wet snow looks probable at river level and definite in the Upper Valley. The major complication with this system will be wind: 40mph at Rooster Rock means blizzard conditions along I-84, a recipe for a road closure at worst and incredibly hazardous, slushy driving at the least.

Snow flurries continue on Mt. Hood today, with a chance of some sunbreaks in the afternoon. The snow level will be 1500′ in the morning and 2000′ in the evening. Approximately .3” WV falls by 4pm for 2-4” of new, with another .2-.3” overnight for 2-3” of new snow by Monday morning. Wind today will be SW 25 early, light and variable midday and W 25 in the evening.

There might be a few flurries Monday morning, but the sun will come out by mid-morning, for mostly clear skies on Mt. Hood, with high clouds moving in late afternoon The freezing level will be 1500′ all day. Wind will be WNW 35 early, 30 mid-morning and 15-20 in the afternoon.

Tuesday starts off cloudy, with snow starting around 4am. The snow level will be less than 500′ (at least near Hood River) in the morning, rising to around 4000′ in the afternoon (with continuing low freezing levels in the Gorge) Given the nature of this system, the snow will likely be heavy and fairly wet, despite the low freezing levels. About 1” WV falls by 4pm, for 8-10” of new snow. Another .4” falls by 4am Wednesday, for another 3-4”. Wind Tuesday will be S 20 early, SSW 35-40 through mid-afternoon and SW 20 in the evening.

Heavy snow continues Wednesday, with the snow level around 3500′ and around .5” WV for 4-7” of snow during the day, with another .5” WV overnight. Wind will be W 25 early, becoming NW 30 in the afternoon.

Have an awesome day today!
