HoarfrostHubb Posted February 26, 2019 Share Posted February 26, 2019 Came close to taking one for the team a little while ago. I was driving my daughter back from her piano lesson in West Boylston. We were on Rte 140, approaching the Rte 290 intersection. I saw a blue flash to the NW. I thought maybe lightning. As we got past 290, there were brake lights ahead. People were turning back. I figured wires down...explains the flash. We had to move further to be able to turn around then I see cars going around what looked like branches in the road. I’m stupidly thinking “I can just go around” onto the shoulder of the road. When it was my turn we start doing that, and my daughter gasps Oh My God... just overhead is a massive pine across the road, but suspended by power lines...we were too late to turn around and we drove underneath it. Darwin award almost given... 2 1 Link to comment Share on other sites More sharing options...

I'd love to see some wind records for the Mansfield COOP site... but if that's legit I've never seen anything higher than like 112mph on that thing. The MWN 171mph Gust makes me think the MMNV1 Gust could be legit. Link to comment Share on other sites More sharing options...

I've watched the MMNV1 COOP obs for 15 years and have never seen anything remotely close to what it's shown the past two hours. Any 100+ wind is usually a rogue gust among 80-90mph gusts in high-end events (often during cutters south flow. I've never seen westerly winds like that.

radarman Posted February 26, 2019 Share Posted February 26, 2019 Hit 52 on the UMass wx station, maybe a top 2 or 3 event. I want to say a similar Feb 2013 overnight fropa rivalled it here. Limbs down all over the valley, partial collapse of a mill in Holyoke, and no power here locally for the past two hours or so. 1 Link to comment Share on other sites More sharing options...

I'll have to look that up. I'm very interested in being able to explain how these summits are hitting winds so much higher than the model wind speeds at 850mb might suggest.

Yeah it’s not mixing down higher winds, it’s accelerating the background flow over. 1 Link to comment Share on other sites More sharing options...

To keep the same amount of air flowing over the mountain it has to accelerate when the depth of flow shrinks. Link to comment Share on other sites More sharing options...

Yeah...that is probably how I should have phrased that. Does this issue with model resolution occur over other mountain ranges, or is there something different about the Whites and Greens?
