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

Happy small business Saturday. You’ll have to define “small business” for yourself when choosing how to spend your dollars, because the concept of small business is a bit complicated… On a completely different topic, kudos to the guy riding his bike down Oak Street this morning around 5:30am. I don’t know who he is, but he’s an animal: all kitted up, going for a training ride in the rain that early. Someone should buy him a hot cocoa (if his diet allows).

In Gorge weather, improvements should be seen today, which won’t help the muddy mountain bike trails (please leave them alone today and let them dry), but will help your road biking chances and your downtown shopping expedition. Tomorrow will be dry, but we’ll likely see inversion clouds in the morning. As the air mass dries out Monday, it’s less likely we’ll see an inversion layer. However, it’s going to be right around freezing, or even below freezing in the Gorge on Monday and Tuesday, all day. That should make the mountain bike trails rideable at low elevations, but they’ll still be too muddy up high.

If you enjoy hypothermia, you should go windsurfing or kiting the next few days. Easterlies start picking up midday Sunday, for low twenties by afternoon. Monday looks like E 30-40, and Tuesday brings easterlies in the 30’s. Temps will also be in the 30’s, but that still gets you to the winter 100 rule of air temp + water temp + wind speed.

On Mt. Hood today, as feared, the weather is providing the wrong kind of precipitation on Mt. Hood this morning. It’s raining at 5000′, and even at 6000′, there’s not much in the way of new snow. A trace, maybe, at best. The precipitation is mainly done for today; we might see another .1-.2” water value, but that’s probably going to fall as rain, with just a few flurries late. By 1pm, we should be seeing sunbreaks. The snow level, at 5500′ early, will fall to 4000′ soon, and then to 3000′ by 10am, holding there for the rest of the day. Wind today will clock around to the NW for 25-30 in the morning, dropping to 20-25 by noon.

Sunday looks clear and sunny – with maybe a few clouds in the morning – all day. The freezing level will be 1000′ (except in the Gorge, where it will be at the surface), with NW wind at 10-15.

Monday also looks clear, with a decent inversion giving sub-freezing temps in the Gorge and just-above-freezing temps on Mt. Hood first thing in the morning. The Gorge stays cold all day, while Mt. Hood sees the freezing level rise to about 8000′. Wind will be light and variable in the morning, becoming WSW 10-15 in the afternoon.

Tuesday starts off with maybe some high clouds and maybe clear skies, and stays dry all day. The freezing level will be around 9000′ with SW wind at 15-20.

Extended range forecasts show snow on Wednesday, with .2-.3” water value giving 2-4” of new. Thursday, Friday and Saturday all look relatively warm and wet. Not drenching, but wet, with models predicting up to 3” of moisture over the 3-day period.

Have an awesome day today!
