Mt. Hood Snow Forecast – 5000′

Good morning,

Just a friendly reminder from my friends at Hood River Rotary: January 21st is the annual Rotary Ski Night at Meadows. Tickets for skiing from 3-9pm are just $10 in advance, $15 at the gate. You can purchase advance tickets now and support a great cause, whether you plan on going or not.

Here we are again. It’s the broken-record-groundhog-day forecast.

On Mt. Hood today, it will be sunny, with high temps around 50. The free air freezing level (FAF) will be around 10,000′. Wind will be W 15mph early, becoming NW 15-20mph in the evening.

Saturday looks clear and sunny, with the FAF at 10,000′ early, rising to 12,000′ in the afternoon. Wind will be W 10mph early and SW 10mph in the evening.

Sunday also looks clear and sunny, with the FAF at 12,000′ all day. Wind will be W 5-10 early and NW 5-10 in the afternoon.

Monday repeats the pattern, with temps in the 40’s-50’s, the FAF at 13,000′, and wind W 15mph.

It appears the end of January high pressure is in sight, with snow and a relatively powerful system hitting Mt. Hood on Wednesday morning.

The valley inversion will continue through this period, although models are insisting it will break down Saturday afternoon for highs in the 40’s at low elevations. Even if that does happen (unlikely), the inversion will return with a vengeance on Sunday. East wind will not help the picture for the gloomy Gorge: Easterlies at 25-30 this morning back off to 5-10 in the afternoon. Saturday brings east wind at 15-18. Sunday brings easterlies at 21-24. Monday sees stronger east wind at 25-30.

The inversion and dry weather will hold through early Wednesday morning, when the protective ridge of high pressure takes a proverbial hike and gets the f**k out of the Northwest. With cold air in place in the lowlands, and easterly flow in place in the Gorge early Wednesday morning, this system could prove particularly problematic, with sticking snow down to river level. Fortunately, the system is powerful enough that it will turn gradients around by Wednesday afternoon, with precip switching to rain.

In events, Dirty Fingers hosts Lance Armstrong’s Oprah interview, part II, tonight at 6pm. On Saturday at 9:30am, NWTA has a work party on the easyCLIMB trail. They billed it as the “worst work party of the year”, but with the forecast looking dry and cool and maybe even sunny (if the inversion really does break, and that’s more likely in Cascade Locks) it could be a great work party after all!

Have an awesome day today!
