The threat of severe weather and even tornadoes stretched across the Northern Plains and the Great Lakes early Wednesday, while most of both coasts were to stay dry and warm.
A weak cold front was to sweep across the Plains, kicking up showers and thunderstorms. A warm front will make its way across the Great Lakes and the Ohio Valley, which could lead to potentially severe thunderstorms. The rest of the central part of the country should see dryer conditions.
The Northeast should remain clear for most of the day on Wednesday due to high pressure. However, clouds and some light rain will move in during the evening hours.
The Gulf states could see showers and thunderstorms as a result of a high pressure system that will push moist air to the coast. The inland areas in the Southeast will see generally clear skies. This high will also drag warm air from the Gulf onshore, so temperatures across the Southeast will get quiet hot.
The Pacific Northwest will see decreasing clouds throughout the day and should see seasonable temperatures. Thunderstorms may crash over the Rockies.
The Southwest will remain dry and hot as high pressure continues to dominate the region. Most of California should expect smoky and hazy conditions throughout the state due to the numerous wildfires that are burning. Temperatures across the Southwest will be in the 90s and 100s, while the desert areas will be in the 110s.
Temperatures in the Lower 48 states in Tuesday ranged from a low of 32 degrees at Truckee-Tahoe, Calif., to a high of 107 degrees at Needles, Calif.
