No dealing with the twice-yearly pledge drive. You’ll also have a chance to win prizes from the sponsors, when I have prizes to give. Thank you again for your support!
Hopefully you’ve been enjoying the snow in the Gorge, because there’s more in the forecast. Looks like we’ll see flurries in the Gorge tonight, but no significant accumulation. On Sunday night, expect icy roads in the Gorge, possibly continuing through the day on Monday, especially above 500′. Snowpocalypse starts around 7am on Christmas, with a very strong east gradient through the Gorge coupled with very heavy incoming precipitation. This is our best chance yet to see I-84 close, as there will be blizzard conditions at Rooster Rock and Cascade Locks. Expect 4-6”+ of snow in the Gorge before a switch to rain after 4pm.
On Mt. Hood, snow continues. The snow level will be at 2000′ early, rising to 3500′ today, dropping to 2000′ tonight (with an inversion in the Gorge). We’ll see .2” water value (WV) this morning, for 1-3” of new snow. Skies become partly cloudy tonight, with flurries. Wind today will be SW 25-30 early, picking up to SW 30-40 this afternoon.
