May 17th, 2005 North Platte, Nebraska Supercell Spin-ups
Last Updated on Monday, 04 January 2010 23:58 Written by Roger Hill
We spent the night in North Platte on the 16th, thus allowing us to stay in the area for the 17th. Everything pointed to strong linear forcing and a quick evolution into a squall line for any storm that formed. By mid afternoon, a triple point became very clear southwest of North Platte. We were able to sit and watch a supercell develop on the triple point. What a treat!!! This storm was fairly high based, but produced several spins ups, a couple tornadic and many on the gust front. Check out the photos below:

Rapid rotation on the southwest flank of this high based supercell.

The question here is whether or not this is circulation is attached to cloud base. I feel it was as there was an area of rotation and what looked like a funnel above the debris.

Here, you can even see it clearer.

Strong outflow dirt racing at 70 mph across this field.

Even though this was high based it had copious amounts of hail to golf ball size.

One of at least half dozen gustnadoes we saw on the gust front.
