Weather Underground Forecast for Sunday,May 29,2016

Tropical moisture will spill over the East Coast on Sunday, while a low pressure system shifts across the upper Great Lakes.

Tropical Depression Two is expected to be upgraded to a tropical storm by Sunday as it drifts west northwestward along the southern Mid-Atlantic. This system will produce high surf and stormy weather across the Mid-Atlantic, bringing threats of flash flooding to eastern South Carolina, eastern North Carolina, eastern Virginia, Maryland, eastern Pennsylvania, New Jersey, southeast New York, Connecticut, Rhode Island and western Massachusetts.

Meanwhile, a low pressure system will push east northeastward across the upper Great Lakes and southeast Canada. A cold frontal boundary associated with this system will stretch southwestward from the western Great Lakes to the southern Plains. Scattered showers and thunderstorms will fire up across the Midwest, the Tennessee Valley, the Appalachians and the Northeast. The tail end of the frontal boundary will stall out over the central third of the country, which will lead to heavy rain and thunderstorms across the central and southern Plains. Severe thunderstorms will be possible in northwest Texas. These thunderstorms will be capable of producing large hail, dangerous straight line winds and isolated tornadoes. Prolonged heavy rain will bring threats of flash flooding to northern Texas and southwest Oklahoma.

A pair of cold fronts will transition across the Pacific Northwest and the Intermountain West. Scattered showers and thunderstorms will be possible across the region. Daytime heating will also trigger isolated showers over the Great Basin and parts of California.
