Weather Underground Forecast for Wednesday,May 11,2016
A low pressure system will drift across the north central portion of the country on Wednesday, while a ridge of high pressure builds over the West Coast.
An area of low pressure will push east northeastward over the northern Plains and the upper Midwest. This system will pack cool temperatures and gusty winds, and is expected to usher light to moderate precipitation across the Intermountain West and the northern Plains. A cold frontal boundary associated with this system will stretch south southwestward from the upper Midwest to the southern Rockies. As this frontal system transitions eastward, it will interact with warm and moist air from the Gulf of Mexico. This will create numerous complexes of rain and thunderstorms across the upper Mississippi Valley, the middle Mississippi Valley, the central Plains and the southern Plains. Severe thunderstorms will be possible in western Illinois, southern Iowa, Missouri, northwest Arkansas, eastern Kansas, Oklahoma and northern Texas. These thunderstorms will be capable of producing large hail, dangerous straight line winds and isolated tornadoes. Heavy rain will bring threats of flash flooding to north central Texas, southeast Oklahoma, eastern Nebraska, southwest Iowa, northern Missouri and western Illinois. Showers and thunderstorms will also develop to the east across the Tennessee Valley, the Ohio Valley and the Mid-Atlantic.
A ridge of high pressure over the eastern Pacific will keep conditions warm and dry across the Pacific Northwest and the Southwest.
