CHASE DATA PAGE FOR 7-13-2009 | SevereWarningSystems.com

This chase was determined a go as to a 10% hatched tornado risk. We were on the west side of South Dakota. After going north through Wyoming and into the Black Hills of South Dakota, we chased east on th I 90 into a spectacular supercell. Although the structure was insane, we opted to abort and proceed north to the higher risk are for tornadoes. The cell we aborted finally put out a rope tornado near Valentine, Nebraska. This was over 7 hours later after this supercell initiated.

This run details in brief for the date of July 13th, 2009.

This chase was full of good structure, some brief funnel clouds, insane hail and straight line winds. The tornado possibility diminished due to the early MCS system that came through earlier minimizing the shear needed for tornadoes. We waited in Buffalo, South Dakota... On the radar a huge supercell eruped on the Wyoming/Montana border. A large tornado was reported in east Montana... We raced south to intercept the cell in prime position. accompanied by insane straight line winds, great lightning show, rotation, and and beautiful rainbow, no tornado ground circulation could be confirmed.

Our search and rescue dog was almost called into action as we proceeded to Newell, South Dakota to witness a significant amount of damage from over 90 MPH straight line winds from this storm. The town resembled damage from a tornado. We were on the scene to witness large trees on stuctures, moderate damage everywhere, and the possibility to have "Terra" demonstrate what she had been trained for. All residents were shaken up. There were no reported injures as to this event in Newell. It was to dark for good photos, although in the pictures below shows the rainbow as we were about 15 miles north of Newell.
