Good morning!

You know you’re overtired when you get a couple of days off and sleep 11 hours both nights. The 6 last night isn’t really cutting it, but I’m up now so you get a forecast. =)

The snow level is back down to a very un-spring-like 2000’ or so this morning, and will hold today. The moisture is staying west of Mt. Hood at this time, so I think the models are over-predicting snowfall during the day today. I think we’ll see an inch or two before 4pm wtih another 2-3” overnight tonight for a total of .3-.4” WV. Winds today will be SW 10-15 early, rising to SW 20-25 by 2pm. The wind will be SW 35-40 overnight tonight.

The snow level tomorrow starts at 1500’, rising to 2500’ by 11am and 4000’ by 2pm. Snow will start around 11am as a cold front moves in, giving us .2-.3” WV during the day for 2-4” of new snow. Snowfall picks up overnight, becoming heavy at times, for .5-.7” WV overnight and 4-6” of somewhat heavy new snow. The wind on Thursday will be SW 20-25 early, rising to SW 30-40 by 11am and picking up to 35-45 by 2pm.

Friday morning should be good on the mountain, with the snow level around 4000’ all day, rising to 6000’ overnight (but we don’t really care about that until Saturday) and snow flurries. Winds Friday morning will be SW 35-40, dropping to 20-25 by 11am and going to W 15-25 after 4pm. Total precip Friday will be less than .25”, for a couple inches of new snow.

The snow level Saturday morning will be 5500’, with a chance of snow mixed with rain, but the snow level will drop to 2500’ by 2pm. Total precip will be .25-.5” but we’ll have to wait a bit and see how the models shake out to know if we’re going to see rain, snow, freezing rain, etc. Winds Saturday will be NW 20-30 early, rising to NW 30-40 by 2pm. Models suggest less wind than that, but you know how those NW’erlies accelerate on Hood…

Sunday looks partly cloudy with flurries on the mountain.

In other news…

The annual Post Canyon Clean-Up Day has been scheduled for Saturday April 16, 2011. That’s this Saturday. It will be held from 9:00am to 12:00pm. All volunteers are to meet at lower Post Canyon Road. You may want to bring warm clothes, work gloves, hat, boots, water, snacks, etc. If you use Post Canyon, show up and help make it a better, cleaner, happier place for everyone!

If you want wind, you’ll have it. Westerlies slowly pick up today as a front approaches and then passes. By noon, you’ll have gusty 16-19 from Stevenson to Mosier, with 22-26 east of Mosier from 2pm to dark, possibly hitting 26-30 for a brief period of time around 3-5pm. Another round of upper teens/low twenties westerlies blows through tomorrow as the second front passes, but it will likely be very gusty and wet. On Saturday, synoptic-scale westerlies set up for mid to upper twenties east of Mosier in the afternoon, after you help out at Post Canyon. =)

Have a great day today!
