Back-to-back powerful Pacific storm systems to impact the Pacific Northwest and northern California through the end of this week with heavy rain, flooding, strong winds, and higher elevation mountain snow. A strong, long-duration atmospheric river will accompany the Pacific storms, bringing excessive rainfall and flash flooding to southwest Oregon and northwest California through the week. Read More >
Overview
This "northwest flow" event (i.e. flow aloft was from the northwest) lead to a number of damaged houses, outbuildings, power poles, trees and other vegetation due to strong outflow winds and two separate microbursts originating from the same supercell thunderstorm. This supercell developed just east of Dumas, Texas and moved south through Amarillo and Canyon. Initially the supercell produced very large hail to the size of baseballs north of Amarillo, and would drop 2 inch hail in Amarillo. The storm produced its first microburst as it started becoming outflow dominant in southern Amarillo where some power poles were damaged. The second more powerful microburst occurred just south of Amarillo and would lead to some considerable damage with winds up to 90 mph estimated based on damage between Amarillo and Canyon along and near county road 1541. During this time, the storm also dumped 2 to 6 inches of mostly dime size hail (although the were some reports of hail up to the size of golf balls as well) along its path. Another storm would become severe briefly near Spearman producing ping-pong ball size hail, but dissipated within an hour or so.
