Mt. Hood Snow Forecast – 5000′

Good morning,

Geez. I’m a little behind the ball today. NOAA’s been all over the freezing rain forecast for a couple of days, and I’ve been slacking off. Well, I’m on board now. It’s 32 degrees at Meadows. It’s 28 down here. It’s going to freezing rain on us a bit this afternoon. It would be doing it now, but the atmosphere is so dry from the easterlies that the moisture is falling and not reaching the ground here… yet. We’ll likely see freezing rain in the Hood River area between noon and 6pm. The western Gorge will probably see it earlier. It shouldn’t be more than .2” of ice accumulation, but it’ll be enough to make a mess. Sorry for the late notice. Uh… you shouldn’t go to Portland or come back this afternoon unless it’s a matter of life or death.

After 7pm today, temps should warm above freezing and the ice will go away. We’ll see a brief switch to light west wind overnight before easterlies return at 21-24 tomorrow afternoon. Yes, it looks foggy in the Gorge tomorrow, at least in the morning, and we might get lucky with below-freezing temps again and super-slick roads. Friday looks very rainy and relatively warm, with temps in the low 40’s. Saturday looks showery.

On Mt. Hood, this system should actually come in as wet snow. The free air freezing level will be 5000′ this morning, falling to 2000′ around 4pm. Light flurries (or maybe light sprinkles) this morning give way to heavier precip around noon, with .4” water value (WV) falling by 10pm, for 3-4” of new snow. The sky clears overnight. Wind today will be SSW 40-50 through the day, dropping to SW 30 at 4pm and swinging to W 30 overnight.

Thursday starts off with clear or high overcast sky above Mt. Hood. The freezing level will be at 1000′ early, rising to 5000′ by 1pm and briefly to 7000′ by 10pm. The sounding model is predicting snow, but the 700mb model shows warm temps aloft. I’m going to call freezing rain out of this system for Mt. Hood, and my apologies to anyone in mountain operations. It’ll start around 10pm, with .3” falling by 4am Friday. Wind Thursday will be WNW 20 early, SW 20 midday and SW 30 overnight.

Friday will likely start with freezing rain on Mt. Hood, switching to snow mid-morning. The freezing level will be 4000′ early, 5500′ mid-morning and 3000′ in the afternoon. Approximately .7” WV falls between 4am and 4pm, for a couple inches of snow if we’re lucky and a lot of ice if we’re not. Snow continues overnight as another frontal system swings through for another .4” WV in the 1am-4am period, for 3-5” of new. Wind Friday will be SW 30-40 all day.

Saturday looks showery, with the snow level at 1500′ all day and .3” WV falling during the day for 2-4” of new snow. Wind will be WSW 30, dropping to SW 20 mid-morning.

Coming up Friday, there’s an avalanche awareness clinic at Dog River at 7pm. This is no substitute for taking a full Avalanche I course, but it will give the basics of backcountry safety. Plus, it will give you a chance to talk to your USFS ranger, Jimmy T.

Have an awesome day today!

1/22 Mt. Hood forecast, Gorge snow, and bye-bye Inversion

Mt. Hood Snow Forecast – 5000′

Thursday

Good morning,

This is it… the last day of the Great Inversion, 2013, or at least the last day where the inversion will result in splendid weather on Mt. Hood. I just looked at the webcams, and the sunrise was gorgeous. That probably means high clouds are already moving in, so if you want sun, hurry up and get it.

In Gorge news, it’s blowing 52mph at Rooster Rock this morning, according to iWindsurf. That wind is driven by a .24 east gradient. Big, but not huge. East flow sticks around long enough tomorrow for some snow, maybe an inch, in the Gorge between 1pm and 4pm, after which we’ll go to west flow and see a switch to rain. Thursday looks dry and cool in the Gorge through 1pm, with rain starting around 4pm. Friday starts off cloudy, and a bit warmer, with temps in the low 40’s, with very heavy rain starting midday. From this far out, the weekend looks showery and cool, which is much better than inverted and gloomy.

On Mt. Hood, high clouds move in sometime this morning. The freezing level will be 11,000′ all day. No precip. Wind will be SW 25 early, picking up to SW 30 in the afternoon.

The freezing level starts dropping overnight, going to 8,000′ at 4am, 6,000′ at 10am, 3500′ by 1pm and 1500′ by 4pm. Snow starts falling around 1pm, which means the snowpack will be cold and hard and not conducive to bonding and we’ll end up with dust on crust on the hill. Total precip will be around .4” water value (WV) between 1pm and 10pm, after which we switch to flurries. Wind will be SSW 40 early, 45-50 at 10am, W 30 at 4pm and a lift-swinging W 40 at 7pm.

Thursday looks colder, with the freezing level at 1000′ early. More on the afternoon weather in a bit. There will be flurries during the day, with no significant accumulation. Wind will be WNW 30-40 early, W 20 at 10am, SW 40 at 4pm and W 35 overnight. Now, on to the Thursday afternoon weather: at 4pm, the snow level will be 1000′, but warm, wet air will move over top, and the snow level will rise to 7000′. In between this period, there will likely be freezing rain on the mountain. Total precip between 4pm and 1am will be .3” WV, which will likely fall as ice, but may fall as a bit of snow.

On Friday, the snow level will be 6500′ early, 5500′ at 1pm and 4000′ at 7pm. Precip amounts are varying across models, but it looks like very heavy rain/snow will fall around 1pm. If it comes in as snow, we’ll be sitting pretty, with wet, heavy snow bonding to the snowpack. Wind will be SW 25 all day.

Have an awesome day today!
