June 22, 2008 Alliance, NE Anticyclonic LP Supercell

Early activity in extreme eastern Wyoming lured us west to Lyman, NE.  The cells were high-based garbage, so we went back east through the Scottsbluff NM.  More interesting convection developed to the east, near Angora, and then to our north, towards Alliance.  I headed towards a somewhat discrete cell on the northwest side of Alliance.  It was moving ENE (the cell was, not the town), and we blasted NNE on 87.  We found ourselves between two storms between Alliance and Hay Springs.  The one to our southeast exhibited a  skinny, high-based, funnel cloud.  The nicely sculpted updraft to our northwest was an anticyclonically rotating low-precipitation supercell.  As it approached Hwy 87, it shriveled quickly and died.
