Weather Summary

Weather Underground Forecast for Wednesday, October 01, 2014

A low pressure system will move across the northern Plains on Wednesday, while a separate wave of low pressure will move over the eastern third of the country.

A strong area of low pressure will lift northeastward over the northern Plains and south central Canada. This system will interact with warm, muggy air over the central U.S. to initiate rain and thunderstorms over a handful of states. Strong to severe thunderstorms will be possible over the upper Midwest, the middle Mississippi Valley, the central Plains and the southern Plains. Severe thunderstorms are forecast to develop over northern Oklahoma, Kansas, northwest Missouri, eastern Nebraska and southwest Iowa. These thunderstorms will be capable of producing large hail, dangerous straight line winds and isolated thunderstorms. Additionally, showers will linger over the Intermountain West. High elevation snow showers will be possible above 8,000 feet across the central and northern Rockies.

Meanwhile, an onshore flow from the Gulf of Mexico will trigger isolated thunderstorms across the Gulf Coast and the southeast. To the north, a wave of low pressure is expected to usher rain across portions of the northern Mid-Atlantic and New England.

Out west, a ridge of high pressure will build over the eastern Pacific. This system will bring warm, dry conditions to the majority of the West Coast on Wednesday.
