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

Sometimes I’m really glad I didn’t get the forecast right. Take today: instead of waking up to a sheet of ice outside my house, I woke up to rain. 33 degree rain, but rain nonetheless. Why rain instead of freezing rain? Best guess is that the pressure gradient across the Cascades decreased faster than expected, allowing the air in the Gorge to warm up. The gradient at 5am was a mere E .02, not really enough to support the ice train. Anyway, we should get enough rain today to wash much of the snow out of the Gorge proper, if not Odell and maybe even Parkdale. And that should be it for Gorge snow for at least a few days. Something worth mentioning is that temps look to be right around freezing or below in the Gorge on Thursday, and this could freeze the ground hard enough to make for some fun mountain biking, assuming today’s rain washes out all the snow.

West wind over the next three days should help keep the snow melting: West 30-35 today, strongest at Arlington, but windy lots of other places too. Go ahead, windsurf or kite if you dare. Lighter westerlies continue on Tuesday and Wednesday.

On Mt. Hood today, it’s going to be wet and windy. The freezing level was around 5000′ at 5am, but it will rise to 7500′ by 7am and hang out around 7000′ pretty much all day. Very heavy snow mixed with rain/sleet/freezing rain early gives way to rain, with 1.7” water value (WV) by 4pm. After that, rainfall tapers off, with only .1-.2” by 4am Tuesday for 1-2” of snow. That’s what the models say. However, the strong wind may give us orographic enhancement, for double the snow. Wind today will be W 40-50 early, becoming WNW 50-55 mid-afternoon and slightly more northwesterly at 50 in the evening.

The snow level will plummet overnight, but it will quickly rise again: 1500′ at 1am, 5000′ at 7am, 7000′ at 4pm and 6500′ at 10pm. Tuesday’s moisture, luckily, will head far north of us, with the North Cascades seeing 2-4” of water value (maybe snow, maybe rain… not really sure because I’d have to pull up a whole difference set of models). We, on the other hand, will just see light snow giving way to light rain for less than .25” water value over the 4am Tuesday to 4am Wednesday period. Wind on Tuesday will be WNW 35-40 early, W 40 mid-morning, and then WSW 50-60 through the evening.

Wednesday looks like a happier day for skiers, with very heavy snowfall starting around 4am. The snow level will be 3500′ early, 1000′ mid-morning, and 500′ in the afternoon. About 1.5” WV falls by 4pm, for 14-18” of new snow during the day. Another .1-.2” WV falls overnight, for a couple inches more by Thursday morning. Wind Wednesday will be SW 50 early, SW 40 mid-morning, and WNW 35 in the afternoon.

Have an awesome day today!

1/6 Mt. Hood rain/snow and Gorge freezing rain forecast

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

Oh wow. This weather is really getting exciting. First off today, the Gorge forecast. Today looks relatively dry, but around midnight, it’s going to get messy. A warm and very wet system comes right over the top of our landlocked sub-freezing air. The gradient won’t switch to westerly until probably 10am on Monday, and that means we’re in for up to .5” of freezing rain between midnight and 10am. We also might see an inch or two of snow between 10pm and midnight. If you don’t have to drive I-84 Monday morning, don’t. Really. Don’t.

The freezing rain should switch to rain by 10am Monday, with accompanying strong west wind. We might see another shot of freezing precip on Tuesday as the next front approaches with east wind through the Gorge, but once again, west wind saves the day around 1pm, bringing warmer weather. Models are totally out of synch on Tuesday’s precip amounts. If the storm track heads north, we’ll stay relatively dry. If it shifts south a little, we’ll take another pounding. Wait and see…

Then on Wednesday, very cold air moves in with heavy precip. Right now, it looks like the snow level will be at 500′, borderline for a river-level snow event, but in the ballpark for 6-8” in Odell and Parkdale.

At this point, Thursday looks dry and cold with enough west wind to give us partly cloudy sky in the Gorge.

Now, since this is really a ski forecast this time of year, here’s your Mt. Hood forecast:

Today looks clear on Mt. Hood early in the morning, with high clouds moving in mid-morning. The free air freezing level (FAF, which doesn’t take the inversion and sub-freezing Gorge temps into account) will be 1000′, rising to 1500′ by 7pm and 4000;+ by 1am. It’s likely we’ll see a bit of snow between 10pm and 1am before a switch to sleet, freezing rain, and then straight-up rain by 4am Monday. Total precip will be .3-.4” water value (WV) between 10pm and 4am. Wind today will be W 20-25 early, swinging to SW 20-25 around 7pm.

Monday looks … interesting. A warm system rides over cold air, giving us freezing rain at 5000′ through 4am. After 4am, we’ll just see rain, as the freezing level rises from 4000′ at 1am to 6000′ at 4am to 8000′ at 7am. It won’t drop to a better level until 10pm, when it falls to 4000′. Mt. Hood gets 1.4-1.6” of rain between 4am and 4pm, followed by another .4” WV between 4pm Monday and 4am Tuesday. That last bit will likely fall as 2-4” of new snow. Wind on Monday will be SW 25-30 early, W 30-40 by 4am, W 45-50 by 7am and WNW 50 at 1pm, becoming more NW late in the evening.

Tuesday’s models are struggling with the location of the storm track. At this point, all that can really be said is that it’s probably going to be borderline for snow vs. rain, with the snow level at 4000′ in the morning rising to 5500-6500′ during the day. The wind will be SW 30-50 (I know, not very specific of me). If the storm track goes north, we’ll be warm but relatively dry. If it shifts south by 100 miles or so, we’ll be warm and drenched. Once again, wait and see.

Wednesday looks much colder, with the potential for a lot of snow to fall on Mt. Hood. Thursday looks cold, sunny, and windy.

Have an awesome day today!
