It appears this may have been a wide spread “blowdown” type event. A series of downbursts, or straight line wind events combined with possible tornadoes tore through the white pines pretty good Tuesday night.
The Duluth NWS has survey teams out today and posted this update today.
•Survey Update (3:54 PM): The survey team is still in the field and assessing the damage. We will post the details when we have more information – either late today, or sometime tomorrow.
•Storm Surveys: The NWS Duluth will be dispatching a storm survey team to Bayfield, Ashland, and Iron Counties today to conduct a damage assessment. We received many reports of damage in these areas and radar signatures indicated the possibility of tornadoes. An unconfirmed report of a tornado was received from the Morse area in Ashland County. The survey team will determine whether or not the damage in the area was caused by non-tornadic thunderstorm winds or by tornado(es).
