Mt. Hood Snow Forecast – 5000′

Looks like Mt. Hood escaped the the south and east of the heaviest rainfall yesterday, meaning there was no chance to test ODOT improvements along Highway 35. The snowpack also escaped the worst of the rain, and continues to build. About 6” fell overnight, and there’s now around 30” on the ground, likely enough to start packing it and grooming it. If you want to hike, keep an eye on that skihood website, as they’ll likely end hiking access in the resort soon.

Briefly, the wind forecast, before the snow forecast: westerlies in the eastern Gorge tomorrow will hit gusty 26-30 in the afternoon. Other than that, it looks like we might see some easterlies next week, if the (unreliable) long-term forecast holds.

On Mt. Hood, the snow level today will be around 5000′, briefly rising to 6000′ in the afternoon and falling back to 4500′ this evening. .6” water value falls this morning as snow, for 5-6” of new. When the snow level bumps up, we might see a brief spot of freezing rain, but most likely this will stay snow. Another .4” WV falls tonight, for 4-5” of snow. Wind today will be SW 30-35 early, picking up to SW 40-50 around 1pm and holding overnight.

Wednesday starts off with the snow level at 5000′, and then a cold front blasts through, knocking it down to 2500′. .5” WV during the day gives us 5-7” of new snow by 4pm, when the weather switches to flurries and partly cloudy skies. Wind will be SW 30-40 early, going to a lift-swinging W 40-50 at 7am and a more powerful WNW 40 at 4pm.

Thursday looks dry, but warm, with high clouds. The snow level will be 1500′ early, rising to 3000′ by 10am and 7000′ by 1pm as a warm system slides over the top of the lingering cold air. Wind Thursday will be W 10-15 early, swinging to SSW 15-20 midday.

Friday looks rainy. Quite rainy, actually. The snow level will be around 8500′ in the morning, falling a touch to 8000′ in the afternoon. Rain starts around 10am, for 1” by 4pm and another .6” by 4am Saturday, when the precip will taper off (although models are not in agreement on this ending of precip). Wind Friday will be SW 30 early, SW 40 mid-morning and WSW 45-50 in the afternoon.

Forecast models for the weekend are still all over the place. The general trend is colder air for the weekend. However, the long-range models (somehow in better agreement), show more warm, wet weather next week. But don’t trust any forecast past 72 hours. People who forecast that far out are just doing it because they love forecasting, not because they believe in what they’re saying!

Have an awesome day today!
