Sunday was the first day in “chase mode” with College of
Dupage’s fifth trip of the year. While
we did not witness any tornadoes (despite our storm being tornado warned
several times), we were treated with a large and laminar-based HP supercell
near Columbus, ND. Despite favorable
ingredients, the storm was very outflow dominant, and never really had that
tornadic look to it. I’m not exactly
sure what the failure mechanism was today.
250 hPa ridging? Too much warm
air aloft? The afternoon environment seemed
rather favorable for rotating supercells (hence SPC tornado watch issuance, and
subsequent upgrade to 5% tornado probabilities in the late afternoon
outlook). Either way, we had an
enjoyable day and look forward to the convective potential later in the week in
Canada.
