It’s the 1st annual Winter Pledge Drive!
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: 
3:53pm: Thank you Chris R., for your support! Have a great night, everyone!

Good morning,
After weeks and weeks and weeks of high-pressure-dominated weather, we’ve slipped into a new pattern: progressive and wet. It looks like this pattern will stick around for the next week, meaning the mountains will wallow in new snowfall and the mountain bikers will make sad faces at bikes hanging on the wall, waiting for trails to dry.
As of last night, Post was really too muddy to ride through the clearcuts. Whoopdee was also too muddy to ride. Not sure about the Syncline, but after tomorrow’s drenching, it too will be gone for sure.
In Gorge weather, this morning looks partly to mostly cloudy. Rain starts up again this afternoon, and doesn’t stop until Saturday morning. Temps will be in the low forties this morning and the mid-forties this afternoon. Wind will be increasing to W 24-28 by early afternoon. Tomorrow, as I said, will be very wet. Temps will be in the low 40’s early, rising to the upper 40’s in the afternoon. West wind blows at 26-30+ in the eastern Gorge in the afternoon. Saturday looks partly cloudy with temps in the upper 30’s early and low 40’s later. Leftover west wind at 28-32 in the desert in the morning slowly fades through afternoon. Sunday looks partly to mostly cloudy with temps in the mid thirties early, rising to the upper forties in the afternoon with west wind at 15-18.

The Hollywood hype and promises of powder issued by the TV stations and Facebook and every other media outlet is not going to make the snow stay snow on Friday. Today, however, especially tonight, should be good skiing. The snow level today will be around 1500′. Snowfall increases after 10am, for .4-.6” water value (WV) by 4pm, giving us 5-6” of new snow. Another .5” WV falls by 4am Friday, for another 5-6” of new. Wind today will be W 25 early, W 30 by 10am, W 40-45 by 4pm and WNW 35-45 by 7pm.
Friday is my favorite kind of day: interesting weather! The snow level at 4am hovers happily at 2000′, but warm air comes over top by 7am, and the snow level rises to 4000’+, rising to 6500′ at 10am. It’ll stay there for several hours, before dropping to 4500′ by 4pm and crashing to 1500′ at 7pm. Precip amounts will be big: 1.5” WV between 4am and 4pm, mostly falling as rain, or if we’re really lucky, falling as very, very wet snow for 2-3” of new. After 4pm, another 1.1” WV moves in, for 8-13” of new snow by Saturday morning. Even if the precip stays snow on Friday during the day, accessing it will be difficult; Wind on Friday will be WNW 40 early, 40-50 by 7am, W 50-60 by 10am, W 60 at 4pm and W 50 at 7pm.
Saturday looks like a fun storm skiing day, although one model suggests more clearing, and one suggests more snow. At this point, I’ll stick with the snowy model, because we need more snow (very scientific, aren’t I?). The snow level will be at 1000′ or less all day with continuing snowfall. We’ll see .6-.8” WV by 4pm, for 7-10” of new. After 4pm, we’ll start seeing breaks in the snowfall, but will probably get another .2-.3” WV overnight, for another 2-4”. Wind on Saturday will be WNW 40 early, going to NW 35-45 by 4pm and dropping to NW 30-35 in the evening.
Sunday starts with flurries, becoming clear, with the snow level at 1000′ or less. Wind Sunday will be NW 25 early becoming W 15-20 by mid-morning and staying there all day.
Light to moderate snowfall and cold temps continue through Tuesday.
Have an awesome day today!
Temira
