Weather Underground Forecast for Wednesday,June 1,2016

Widespread thunderstorms will continue across the central and eastern thirds of the country on Wednesday, while warm weather persists over the Southwest.

A slow moving low pressure system will drift east northeastward across the northern Plains, the upper Midwest and south central Canada. Light to moderate showers and isolated thunderstorms will accompany this system, affecting eastern North Dakota, northern Minnesota and parts of Wisconsin. A cold frontal boundary associated with this system will extend south southwestward across the upper Mississippi Valley, the central Plains and the southern Plains. This frontal boundary will spawn multiple clusters of thunderstorms over the Midwest, the Tennessee Valley, the Deep South, the southern Plains and the central Plains. The strongest storms are expected to fire up across the southern Plains on Wednesday. Prolonged heavy rain will bring threats of flash flooding to Texas, southern Oklahoma and southwest Arkansas. The same frontal boundary will interact with the remnant low associated with Tropical Storm Bonnie. This interaction will lead to showers and thunderstorms over the Mid-Atlantic and the Southeast. Flash flooding will be possible in eastern North Carolina and southeast Virginia.

Out west, a Pacific cold front will initiate light showers across western Washington. A ridge of high pressure will keep warm and dry weather in place over the Great Basin and the Southwest. Afternoon temperatures will spike 10 to 20 degrees above normal in a handful of states.
