Weather Underground Forecast for Thursday, October 24, 2013.
A ridge of high pressure will continue to build along the coast of California on Thursday, while a cold front will stretch from the Intermountain West to the lower Mississippi Valley.
Cool, dry conditions will persist in the Pacific Northwest on Thursday, as temperatures are expected to range between the 50s and 60s during the day. To the south, clear conditions will also persist, with temperatures ranging between the 70s and 80s. The southern California and Arizona deserts may experience temperatures in the lower 90s due to a high pressure system along the southern California coast.
A cold front will extend from the Intermountain West, through the southern Plains and into the lower Mississippi Valley, which will push cold air across the central third of the country. Light to moderate rain will be possible in northern Montana, while a mixture of rain and snow will impact northern Minnesota, northern Wisconsin, Michigan, Pennsylvania and New York. Northern New England will likely experience heavier snow showers due to a low pressure system along the U.S. Canada border. Along the eastern tip of this cold front, a low pressure system will usher wet weather into the southern Ohio Valley, as well as parts of the Mid-Atlantic and Appalachian states. The majority of the Southeast will avoid precipitation, while the southern tip of Florida may experience spotty showers and thunderstorms.
Temperatures in the Lower 48 states Wednesday have ranged from a morning low of 17 degrees at West Yellowstone, Mont. to a high of 89 degrees at Marathon, Fla.
