Last day of the first annual February pledge drive. Please make a donation now, and thank you for your support!

Thank you for using this forecast! It’s free to use, but it’s not free for me to write. I put about an hour a day into creating a (hopefully) accurate forecast, and I pay for the hosting on this website. If you use this forecast to pick the good days on the hill or on the river, if you find this report saves you gas money or time, please make a donation during pledge drive month! 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 pledge drive. Here’s how this works. If I get donations totally $15 or more today, I post a forecast tomorrow. To make this fair, I’ll try to update the color of the dot midday (a girl’s gotta work, you know.)

Tomorrow’s forecast status: Thank you so much for all your donations during pledge drive!

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

Good morning,

Rain on the mountain. Blech. I know it’s good for the snowpack – more water equivalent is good for farmers and kayakers and gardeners and everyone who likes to drink water during the summer. But I would prefer snow in the snowpack to rain in the snowpack.

In Gorge news, today is going to be wet and mild, with temps in the mid-forties with light wind. Tomorrow brings light wind… hard to tell if we’ll see inversion clouds, but it does look warm – in the 50’s in the afternoon. Saturday also looks warm, with temps in the 50’s midday under clear sky in the morning and clouds in the afternoon with light wind becoming west in the afternoon. The Gorge will see a few rain showers Saturday night, with snow possible in Parkdale. Sunday looks much colder – in the low 40’s, with west wind at 24-28+.

I really thought we might sneak by with snow this morning, but at 4:30am, it was already alternating between rain and snow on the flanks of Mt. Hood. With temps forecast to rise, the inevitable outcome is a switch to rain. So, the snow level at 7am will be 6500′, rising to 7500′ by 4pm and briefly dropping to 6000′ overnight. We’ll get 1” or so of water value (WV) today, for no accumulation other than water in the snowpack. We’ll get another .2-.4” WV overnight. Same thing. Water in the snowpack. Wind today will be W 25-35 early, rising to W 30-40 around 4pm.

Tomorrow looks warm and dry on the mountain and, for that matter, in the valleys. The freezing level will be at 9000′ all day with partly cloudy sky. Wind will be WSW 20-25 early, becoming SW 20-25 in the evening.

Saturday starts off dry and warm and clear, becoming cold and snowy late. The freezing level will be 9000′ early, 6500′ by 4pm, and then will plummet to 1500′ by 10pm. Snow starts falling around 7pm, for .3” WV by Sunday morning and 2-3” of new snow. Wind Saturday will be SW 20 early, 30 early afternoon and WSW 40 overnight.

Sunday starts with mixed flurries and sunbreaks, becoming clear midday and partly cloudy late. The freezing level will be 1000-1500′. Wind will be WNW 30-35 early, NW 25-30 by mid-morning and N 10-20 in the evening.

Your events reminders: On Thursday, in Portland, Friends of NWAC has a fundraiser for NWAC (the REAL mountain weather and avalanche forecasters). Get tickets here. Coming up next weekend, there’s a WTA trail work party at Syncline both days. Sign up for the work party here. There’s also a competing work party at Spaghetti Factory in Post Canyon on Sunday.

Have an awesome day today!
