We are still working to restore power . '' Firefighters went out to assess another reported tornado 6 miles east in Goff but did n't come across any damage , according to Swart . A tornado 's heading your way : Now what ? Later on Tuesday evening , strong winds -- which National Weather Service reports said may have been a tornado , though local police said they were more likely the result of potent straight-line winds -- caused damage near Waterford , Pennsylvania . This northwestern Pennsylvania town is about 15 miles south of Erie . The storms came a day after straight-line winds of up to 80 mph whipped the Springfield , Illinois , area . A microburst spawned by a severe thunderstorm damaged about 70 trailers . Oklahoma : One week later . `` The damage occurred from debris . Tree limbs at a height of 10 to 20 feet were broken and they damaged the roofs of the mobile homes , '' said David Butt , director of the Sangamon County Office of Emergency Management . `` No roofs were torn off . No roofs were peeled back . The only damage to roofs was being penetrated by wind-blown debris . '' One person suffered a minor laceration in the process , Butt said .

Areas most likely to see such conditions include much of central Oklahoma , Nebraska and Kansas .
