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

As you might have heard, today is the HRATS mega work party in Post Canyon. Meet at 10 Speed Coffee on 13th. For your effort, you’ll be rewarded with snacks, prizes, and drinks, warm and cold. Also today, HRVHS Nordic is holding a fruit fundraiser. Swing by the McCurdy Farms fruit stand, just south of Portland Driver on Tucker Road, and buy some fruit to support your Nordic kids. Well, they’re not Nordic, but you know what I mean.

On to the scary weather forecast: I think the timing of tomorrow’s system is going to save us from a bad early-season snowstorm or ice storm. Although models think we’ll see east wind through tomorrow evening – usually a sign of snow in the Gorge – daytime temps are going to be a little bit high for accumulation at river level. Parkdale might see a couple inches before the precipitation switches to rain, and Hood River may see wet flakes for a while. Expect the mixed precip to start between 1pm and 4pm tomorrow.

The story is similar on Mt. Hood. Today starts off sunny with the freezing level below 500′. In the afternoon, Mt. Hood sees a few orographic snow showers for around an inch of new snow, at best. Wind today will be NW 5-10 early, swinging to N 15-25 this afternoon.

Sunday starts with high clouds and the freezing level at the surface. The freezing level slowly rises to 1500′ by 1pm, 3500′ by 7pm, 5500′ by 10pm, and 6500′ overnight. Total precip will be .1-.2” water value before 4pm, followed by 1.2” water value overnight. I think the 5000′ level will see 1-3” of snow or a mix of snow and freezing rain before a switch to rain overnight. Above 6500′, expect 4-18” of snow, with accumulation rising with elevation. Wind on Sunday will be NW 20 early, swinging to W 15-20 midday and SW 25-30 in the afternoon.

Monday morning starts with continued rain on Mt. Hood, as the snow level hovers around 6500′. It will drop to 6000′ by 1pm and 4000′ by 7pm, but by the time the snow level drops, precip will have ended. Total precip on Monday will be .8-.9” water value by 4pm, and this will fall as rain at 5000′, with 4-8” above 6500′. Wind on Monmday will be W 40-50 early, slowly dropping to W 25 by noon.

In the long term forecast, pretty much all of next week looks relatively dry. The next system is forecast to swing through next Friday, but at this point, it looks much like the system we’ll see this Sunday, so not ideal for low-elevation snow.

Have an awesome day today!
