The nation's weather

Conditions in the Upper Great Lakes and the Ohio Valley will improve on Thursday as the strong storm system in the Upper Great Lakes exits the region and moves into eastern Canada. Only a few snow showers will be possible in parts of northern Wisconsin and Michigan during the day as cold air pushes in behind the system. The brunt of precipitation associated with this system will advance into the Northeast due to an associated cold front. Light to moderate rain showers with isolated thunderstorms are expected in the region throughout the day. Showery weather will also be possible down the Eastern Seaboard as the cold front approaches the East Coast.

Meanwhile, the trough of low pressure over the Eastern U.S. will direct Tropical Storm Sean northeastward through the nearby western Atlantic with some acceleration. Strengthening of Sean is expected on Thursday and the storm may reach Category 1 strength. The center of Sean is expected to pass northwest of Bermuda on Friday morning.

In the West, generally calm weather conditions will persist in the continental West as high pressure remains the dominant weather feature of the region. Outside the mainland, conditions will begin to improve in western Alaska as the near-record breaking low pressure system that brought extremely dangerous winds and precipitation to the region on Wednesday weakens. Expect cold and windy weather to persist in the state. Temperatures in the Lower 48 states Wednesday have ranged from a morning low of -2 degrees at Bryce Canyon, Utah to a high of 84 degrees at Hollywood, Fla.
