Weather Underground Forecast for Wednesday, May 14, 2014

Severe thunderstorms will be possible from the central Gulf Coast to the Ohio Valley on Wednesday, while warm, dry conditions will persist across the West Coast.

A cold frontal boundary will extend from the western Gulf Coast to the eastern Great Lakes on Wednesday. As this system intersects a very warm, muggy air mass from the Gulf of Mexico, widespread rain and thunderstorms will result across a handful of states. Strong to severe thunderstorms are forecast to develop over the central Gulf Coast, the Tennessee Valley and the Ohio Valley. These thunderstorms will be capable of producing damaging straight-line winds and heavy hail. Rain and thunderstorms will also be possible across the southern Plains, the Mississippi Valley, the upper Midwest, the Southeast and the Mid-Atlantic. New England will stay mostly clear of wet weather.

A weak area of low pressure will dip south southeastward over the upper Intermountain West on Wednesday. Scattered showers will be possible across Montana, Wyoming, northern Colorado, northwest Nebraska and western South Dakota. Meanwhile, a strong ridge of high pressure is forecast to build over the Great Basin. This system will produce offshore winds across California, which will lead to very warm, dry conditions across the region. Temperatures are expected to range between the 90s and 100s across the state. Some areas across California may experience record high temperatures as a result of this high pressure on Wednesday.

Temperatures in the Lower 48 states Tuesday have ranged from a morning low of 10 degrees at Laramie, Wyo. to a high of 96 degrees at FENTRESS NALF, Va.
