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

Good morning,

Well, it’s another winter morning in the Gorge, and today we’re starting off with some monster west gradients through the Gorge: .17/.09/.43. That should give us westerlies at 35+ at Maryhill and Arlington early, but they’ll back off to gusty 26-30 fairly quickly. Tomorrow brings another round of west wind at 24-28. We’ll see rain in the Gorge this morning, backing off to showers (at worst) this afternoon. Tomorrow also starts off with rain, and also backs off to showers. Thursday looks dry, but will likely be cloudy in the Gorge. Friday brings a better chance of warmer, clearer weather.

Up on Mt. Hood, it’s storming like a ************ this morning, despite the telemetry reading the same speed and direction as yesterday, when it was just storming like a *****. The snow level is around 4000′ right now, and should climb to 6000′ by 10am, and possibly as high as 6500′ by 4pm. We’ll see .6” water value (WV) by 4pm, heaviest early, for 3-6” of new snow, depending on when/if this switches to rain. Personally, I’d prefer we just see wet snow today, but the sounding model is insisting that won’t happen. It looks like it will rain overnight, with .4” WV by 4am Wednesday. Wind will be NW 45-50 early, 40-50 for the rest of the day, finally dropping to 35-40 around 4pm.

Wednesday starts off with heavy precipitation, and with models predicting the freezing level at 7000′, this likely isn’t going to be the correct kind of mountain precipitation. The snow level will drop to 5500′ at 10am, 4500′ at 4pm, and hover around 5000′-5500′ overnight. Around 1” WV of precip falls by 4pm, with rain at first and 2-4” of snow next. Another .3-.4” WV falls overnight, for 2-4” of new snow by Thursday morning. Wind Wednesday will be WNW 50 early, 45-50 by 4am, W 40-45 for the rest of the day, slowly dropping to WNW 35 in the evening.

Thursday sees the end of the storm cycle, with partly cloudy sky. The free air freezing level (FAF) will be 4000′ early, rising to 5500′ in the afternoon. Wind will be WNW 10-15 all day.

Friday looks clear and warm, with the FAF at 8500′ all day and wind NW 10 early, S 15 late.

Saturday looks clear, and Sunday brings light precip of some sort.

Have an awesome day today!
