Powerful storms ripped through parts of Michigan damaging two ice arenas and other structures, and felling branches near the University of Michigan's main campus. The National Weather Service says its crews were surveying damage to determine if one or more tornadoes touched down overnight in places including Ann Arbor, the home of the University of Michigan. Meteorologist Sara Schultz says no tornadoes were confirmed as of Wednesday morning and that the damage was caused by a line of thunderstorms moving eastward into Michigan from Iowa, Wisconsin and Illinois. Ann Arbor Public Schools says some buildings suffered structural damage and many lost power.

A long-lasting weather pattern is blasting hot air across the eastern U.S. and threatening to shatter record highs. Cities like New York, Philadelphia, and Atlanta are experiencing unusual April heat. Forecasters say the near-record temperatures could last into the weekend. The heat Wednesday follows severe storms in Kansas, Minnesota, and Wisconsin. More storms are in the forecast Wednesday in the Midwest. Experts note the duration of this heat wave is rare for April. The heat can be stressful on the human body, especially since many have not yet acclimated to higher temperatures.

A super typhoon steadily battered a pair of remote U.S. islands in the Pacific Ocean with ferocious winds and relentless rains. The storm shredded tin roofs and forced residents to take cover from flying tree limbs on Tinian and Saipan, which are home to 50,000 people. A spokesperson for Saipan's mayor says preliminary reports of damage from Super Typhoon Sinlaku include a lot of flooding, uprooted trees and downed power lines. There were no reports of deaths. The National Weather Service says the tropical typhoon was packing sustained winds of up to 150 mph when it made landfall on the islands.
