The Fierce
Winds Slams into Eastern Washington on June 21, 2005
During the evening of Tuesday
June 21, a pair of thunderstorm complexes traveled across extreme eastern Washington.
What made these thunderstorms so unusually was not the rain or hail they contained,
but the fierce winds they produced. The outflow from these high based thunderstorms
measured over 60kts from the NWS Doppler weather radar. As the storm traveled
over the Columbia Basin and the Palouse, the winds pick up dust, dirt and sand
producing a black back drop of the approaching storm.
Here are some top wind reports
from that evening...
