Wind storm, and a snow storm... on May 31st!?!?

Snow is quite a normal occurance around here, but not on the last day of May.  Yes, it snowed on Sunday, May 31st.  IMG_2168.JPGThe snow didn't accumulate, it just melted soon after reaching the ground.  I went out on Monday morning to see if snow accumulated at Sugarbush.  I didn't see any accumulation, but there was something that looked like snow that hadn't melted from the winter. 

The snow was caused by a strong cold front moving through the region, bringing with it very windy conditions and much colder temperatures.  A wind IMG_2209.JPGgust of 43 mph was recorded in Waitsfield, along with an 11 degree temperature drop in just over a half hour. The wind brought down trees  all over the region, including this one on the East Warren Road in Waitsfield. This tree knocked out power to the Round Barn, about a 1/2 mile away, right in the middle of a wedding!  Our power was out for a few hours as well.

Vortex 2's first tornado intercept!!

The Vortex 2 team (for more info about Vortex 2, click here) finally intercepted a tornado on Friday, June 5th in Goshen County, Wyoming.  The tornado was rated an EF2 on the enhanced fujuta scale, after anaylizing Vortex 2's data.  The mobile sticknets (portable weather sensors / data collectors) that were deployed revealed that the ground level wind speed v2 tornado 4.jpgwas about 130 mph, making this tornado a strong EF2.  The tornado was over open farmland, so damage was minimal. Some of the reported damage included a tree that was completely uprooted, a telephone pole that was snapped at it's base, and 4.5" hail that destroyed the winshield of a Vortex 2 vehicle.  Had there been no wind data recorded by the Vortex 2 team, the Nationv2 tornado 3.jpgal Weather Service would have rated this tornado an EF1, based on the snapped telephone pole.  Telephone poles can snap at winds of around 118 mph.

The whole event was broadcast LIVE on The Weather Channel.  This was the first time in history that the entire lifecycle of a tornado (the development, the time it's on the ground, and the dissipation) was caught on camera.  Meteorologist Mike Bettes was reporting live a few miles away from the storm, and Dr. Greg Forbes anaylized the storm from The Weather Channel's studio in Atlanta, GA. 

If you missed it, you can watch the entire 110 minutes on my YouTube channel. If you want just the tornado, skip to clips 4, 5 and 6.  click here to start at clip 1. Or go to youtube.com/localweatherwiki and click on playlists.

 Triple WWW: Weekly Weather... What??

Do you know what the heat index is? Well, here's the definition from the National Weather Service: "The Heat Index or the "Apparent Temperature" is an accurate measure of how hot it really feels [to your skin] when the Relative Humidity is added to the actual air temperature"

For example: If the air temperature is 90, and the humidity is 50%, the heat index, or the "feel like temperature", would be 94.  But if the humidity was more like 70%, it would feel like a sweltering 106, even though the air temp is 90.  If it was a super humid day, and the humidity was 90%, the heat index would be an astonishing 122 degrees!

Your Questions!

  Do you have a weather question? If so, please send it to me at sugarbushvermont@aol.com, or @reply me on twitter, at http://twitter.com/localweather. (make sure you have @localweather somewhere in your tweet) please include your name and state (such as Josh, Vermont)

Reader observations and pictures

I received 1 weather picture submission, and it will be in next week's newsletter. So, do you have weather related pictures or even just a weather observation? If so, PLEASE send them to sugarbushvermont@aol.com, or @reply me on twitter with a link to your picture on TwitPic. (again, make sure @localweather is somewhere in your tweet!)

Also, your doesn't have to be severe weather damage, or anything like that. It can be a picture (or observation) of a sunny day, a thermometer showing a really cold day, or a really warm day. Any kind of weather picture (or observation) is fine. please be sure to include your first name, and your city and state, so I know where the picture is from!

News about the newsletter

Beginning next week, the localweather newsletter will be sent on a bi-weekly basis, or every other week, most likely the first and third Friday of each month.  Next week's newsletter will be a shortened one, and released on Wednesday, since I want to have one more issue sent before the last day of school.

Corrections: there was a typo stating that 0.99" of rain fell on May 23rd. This was incorrect.  No rain fell on May 23rd.
