Derecho Approaching Watertown SD - Tornado Siren Ambience - May 12/2022 Derek Thompson 2022-05-16 | I filmed the first two clips before going inside as the derecho approached Watertown, South Dakota. The sirens heard faintly during clip one were sounding for a confirmed quasi-linear convective system (QLCS) tornado south of Watertown moving north. That tornado caused extensive damage in Castlewood.Clip two was cut short as I had to get inside before the gas station staff closed and secured the doors. The man speaking in the last clip is one of several truck stop customers taking shelter from the storm. It's not me.Our mobile mesonet truck (seen during clip two under the hotel sign) sampled a peak wind gust of 81 mph with a one-minute average wind speed of 60 mph as the leading edge of the derecho overtook the vehicle.The National Weather Service in Aberdeen, South Dakota published the following event summery on the derecho and tornadoes that occurred: weather.gov/abr/StormsummaryMay122022What is a derecho? weather.gov/lmk/derechoWhat is a quasi-linear convective system? weather.gov/lmk/squallbow*****The mobile mesonet maximum and average wind speed graph can be viewed here: twitter.com/derek605wx/status/1524893152582283264?s=21&t=TA_RcIvJmmkBFvqCscgLgg*****Real-time dashcam video of the derecho overtaking our mobile mesonet vehicle: youtu.be/dYyxAVRtyj4Dashcam timelapse footage: youtu.be/ridbDEXPJMYLocation: Stone's Truck Stop in Watertown, South Dakota (Codington County) at the intersection of Interstate 29 and Highway 212Siren Model: Federal Signal 2001-130Siren Signal: Steady/AlertCamera: iPhone 13 Pro MaxMy email and social media links can be found here: http://www.derek605wx.com************************************Copyright © 2022 Derek Thompson************************************

The mobile mesonet is mounted to the roof of the truck and records high resolution, scientific-grade surface measurements every 1-second for wind speed, wind direction, atmospheric pressure, air temperature, relative humidity, dew point temperature and solar radiation.The following values are updated every 1-minute on-screen: WIND, GUST, PRESSURE, TEMPERATURE, HUMIDITY and DEW POINT. All these measurements (other than GUST) are a 1-minute average derived from sixty 1-second measurements. The GUST value is NOT an average and represents a peak 1-second wind gust sampled during the 1-minute timeframe.The ALL TIME - GUST value is the highest recorded 1-second gust that was sampled on a deployment. If this value is reset, a message will be posted to the YouTube Live Chat.The MINIMUM PRESSURE value (displayed during hurricanes) is the lowest 1-second pressure measurement sampled during the deployment.The HEADING value is updated every 1-second using GPS.1) Wind data is corrected using a fluxgate compass and GPS antenna to derive a true wind speed and direction value while the vehicle is moving, regardless of speed or direction of travel.2) Pressure data is corrected to sea level using GPS elevation data.3) Occasionally, GPS data may drop-out for a second or provide erroneous data for the wind and/or pressure calculation. For example, when accelerating quickly, the GPS vehicle speed may be slow to respond causing an incorrect high wind speed value to be displayed. Automatic quality control will flag these events in the datalogger, but not for the on-screen display.******************************FAQ - Technical Information******************************Computer: Panasonic ToughbookComputer OS: Windows 10Stream Software: OBS StudioStream Camera: Rove DashcamMM Datalogger: Campbell Scientific CR6MM Datalogger Software: LoggerNetSounding System: Windsond, iMet and VaisalaSounding Image Generator: SHARPpyMM = Mobile Mesonet*******************Copyright Notice*******************Anyone using my content without a valid license, or without prior written approval from me, my company, or my media broker, will be issued a DMCA Copyright Takedown Notice through YouTube.

All these measurements (other than GUST) are a 1-minute average derived from sixty 1-second measurements. The GUST value is NOT an average and represents a peak 1-second wind gust sampled during the 1-minute timeframe.The ALL TIME - GUST value is the highest recorded 1-second gust that was sampled on a deployment.

Category 5 Hurricane Michael - Panama City, Florida - October 10/2018 Derek Thompson 2022-05-18 | I deployed to Florida with three mobile mesonet trucks for what eventually became Category 5 Hurricane Michael. Home base was in Panama City, Florida.On October 9/2018, I set out with a few collogues to deploy several scientific-grade weather stations along the Florida coastline to record one-second wind and pressure data as the storm made landfall. Later that day, I coordinated with Mark Sudduth w/HurricaneTrack to finish deploying his remote cameras and a couple weather stations before returning to the hotel for the night.The hurricane made landfall on October 10/2018. I remained at the hotel to film the storm while Mark and Brent drove to Mexico Beach to deploy a camera system last minute. You can watch what that camera captured at the links below.*****Edited video: youtu.be/f3ofAJSqpLMUnedited video: youtu.be/W7aHHnAA8cY*****During the storms peak intensity, we all stayed at the hotel for safety reasons instead of venturing out to deploy a special weather balloon payload in the eye. After the storm, Mark and Brent made their way back to Mexico Beach to retrieve the camera system.My mobile mesonet truck seen in the video measured a peak wind speed of 94 mph with a minimum pressure of 940 hPa.*****Mark Sudduth/Hurricane Track Documentary: Tracking The Hurricanes 2018: youtu.be/sO0tXG8Z1cE*****Storm Chase Area: Panama City, FloridaCamera: Apple iPhone 8 PlusMy email and social media links can be found here: http://www.derek605wx.com************************************Copyright © 2018 Derek Thompson************************************

Storm Chase Timelapse - May 12/2022 (Watertown SD Derecho) Derek Thompson 2022-05-16 | I left Sioux Falls around 10 AM for the forecasted high wind event that later verified as a derecho. I made my way north on Interstate 29 towards Brookings before turning west on Highway 14. I stopped near Huron where I prepped a radiosonde and launched a sounding around 3 PM. As the sounding finished, the line of storms was quickly approaching the Huron area. I made my way north, then east along Highway 212. I planned on intercepting the derecho near the Interstate 29 corridor in Watertown.When I made it to Watertown, I scoped out a couple areas where I could safely ride out the storm. I eventually settled on Stone’s Truck Stop along Highway 212 at the Interstate 29 interchange. This area was fairly open to the south allowing the mobile mesonet to obtain accurate wind measurements.I made the decision to shelter inside the truck stop as the storm approached. Several QLCS circulations were present along the leading edge, including a confirmed tornado in Castlewood to the south of Watertown.The mobile mesonet sampled a peak wind gust of 81 mph with a one-minute average wind speed of 60 mph as the leading edge of the derecho overtook the vehicle.iPhone video of the derecho approaching Watertown with tornado sirens: youtu.be/UrKneW746TEReal-time dashcam video of the derecho overtaking our mobile mesonet vehicle: youtu.be/dYyxAVRtyj4*****The Huron sounding data can be viewed here: twitter.com/derek605wx/status/1524858131230105600?s=21&t=TA_RcIvJmmkBFvqCscgLggThe mobile mesonet maximum and average wind speed graph can be viewed here: twitter.com/derek605wx/status/1524893152582283264?s=21&t=TA_RcIvJmmkBFvqCscgLgg*****Storm Chase Area: Watertown, South DakotaCamera Model: GoProMy email and social media links can be found here: http://www.derek605wx.com************************************Copyright © 2022 Derek Thompson************************************
Storm Chase Timelapse - May 11/2022 Derek Thompson 2022-05-16 | I left Sioux Falls around noon and made my way south towards Sioux City on Interstate 29. I waited near the Vermillion exit for a while before turning back north and pursuing the storms that started to develop southwest of Lennox. I tracked the storm from the Lennox area up through Montrose. Once the storms started to weaken, I made my way eastward through Sioux Falls along Highway 42 before ending the day near Renner.Storm Chase Area: Southeast South Dakota around Lennox, Montrose and Sioux FallsCamera Model: GoProMy email and social media links can be found here: http://www.derek605wx.com************************************Copyright © 2022 Derek Thompson************************************

I ended up staging near Faulkton and intercepting my first storm of the day approximately 10 miles southwest of Ipswich, where the mobile mesonet sampled winds gusting up to 55 mph while stationary near the intersection of 358th Ave and 142nd Street.I Eventually made my way north into Aberdeen where two QLCS circulations formed on the west side of town prompting a Tornado Warning. I only observed a couple funnels to my west as I made my way into Aberdeen; no tornado was observed.Video of my drive through Aberdeen with the sirens sounding: youtu.be/zR1NIJH89R4Storm Chase Area: Northcentral South Dakota (East River) around Ipswich and Aberdeen.Camera Model: GoProMy email and social media links can be found here: http://www.derek605wx.com*************************************Copyright © 2022 Derek Thompson*************************************

I was told by City maintenance that they opted to power off this siren indefinitely and to reinstall their 2001-130.My last project for Valley Springs was coordinating the reinstallation of their 2001 with West Shore Services in 2015. This project raised the siren from a 30 foot rotted/skinny pole to a new 50 foot Class II pole.
