Derecho putters out

 

06/13/2013 UPDATE:

A line of thunderstorms packing heavy rain and high winds is spreading across southern Wisconsin, downing trees, knocking out power and causing part of a Walmart roof to collapse.

In Lake Delton, the roof of a Walmart near shipping and receiving collapsed during a downpour Wednesday afternoon. Fire Chief Darren Jorgenson says two employees had minor injuries, but no customers were hurt.

The National Weather Service says winds estimated at 60 mph blew through Columbia County in south-central Wisconsin.

Emergency Management Director Pat Beghin says the storm knocked down trees and caused some power outages. No injuries are reported.

In Richland County, a wind gust estimated at 60 mph was reported around 4:30 p.m. in Port Andrew.

Street flooding was reported in parts of the village of Boscobel in Grant County.

In Dane County, no major damage was reported. There were some downed trees. Winds were clocked at around 35 mph in Madison and Middleton.

MILWAUKEE (AP) _ Meteorologists are tracking a so-called derecho weather pattern in the Midwest that could spawn severe windstorms in major metropolitan areas with gusts as strong as 100 mph.

The National Weather Service says derechos occur once or twice a year in the central U.S. with winds of at least 75 mph. The storms maintain their intensity for hours as they sweep across vast distances, and can trigger tornadoes and large hail.

Meteorologists say the windstorms could hit from South Dakota to Pennsylvania over the next two days, including the Milwaukee, Chicago, Detroit, Cleveland and Pittsburgh metro areas.

NBC 15 Meteorologist Charlie Shortino thinks the effects of the derecho will likely hit to the south of the Madison area, although we do have a chance for severe storms Wednesday afternoon.
