A friend found this incredible piece of video circulating the Internet rounds this month of what happens when 110 mph winds slam into a ski lift.
The video is from the Sublette Chair at Jackson Hole, Wyoming's ski resort, taken on March 30, 2010 around 9:45. It shows what happens when a microburst of snow and wind hit just as an unlucky group of skiers were stopped up on the lift.Upside-down storms can do damage too...

As the Pacific Northwest deals with a stretch of stormy weather this week, I suppose it could be worse.
A frequent blog reader who is living here now but from New Zealand sent me a great article highlighting a storm that rolled into Wellington on March 12.
The photos there are incredible, but check out these videos I found on YouTube documenting the storm as it rolled onshore. (Some of these are sped up in time lapse format):High-winds blowing in mountain snow, main street rain

Now how can I say this Looking at the average temperatures from November through March at Seattle-Tacoma Airport , the last winter was 1.8F above normal , including the remarkable warmth of January . Examining the temperature predictions using high-resolution models embedded in global climate models , driven by an aggressive increase of greenhouse gases , one find that this corresponds to the expected changes around 2040.

Local Weather Update A few media outlets are starting to talk about a climatic impact of the Iceland volcano , but they shouldn't be . First , this is really a pretty modest event . But even more important , it is NOT ejecting large amounts of sulfur dioxide into the stratosphere , which is the main way volcanoes alter climate . As noted in my last blog , sulfur dioxide combines with water vapor to create small sulphuric acid particles that scatter some of the sun's rays back into space . We have satellites that can measure sulfur dioxide SO2 from space , one of them being theIceland's Volcanic Eruption: Will it influence weather and climate?

After passage of a Pacific front last night , the freezing level has plummeted to approximately 1500 ft . Snow level is roughly 1000 ft below that . The winds in the lower atmosphere are from the northwest and the lowlands will be mainly rainshadowed from the incoming instability showers over the Pacific . The mountains on the other hand will AGAIN be hammered with snow . with 1-2 ft in many locations . I don't expect much snow action reaching sea level due to the marginal temps and lack of precipitation , with one exception--there could be a weak convergence zone today .
