Weather Underground Forecast for Tuesday,June 28,2016
A cold frontal boundary will generate active weather over the Plains on Tuesday, while temperatures spike above normal over the Intermountain West and the Great Basin.
A wave of low pressure will transition slowly across the Northeast on Tuesday. This system will usher rain and thunderstorms over the eastern Great Lakes, New York and New England. A pair of cold frontal boundaries will extend southwestward over the East Coast and the Deep South. Widespread thunderstorms will develop along and near this frontal boundary as warm and moist air pools across the system. A ridge of high pressure will build just north of the frontal boundaries. This high pressure system will bring a blast of cool and dry air to the upper Midwest.
Meanwhile, the tail end of the aforementioned frontal boundaries will initiate strong to severe thunderstorms over the Plains. Severe thunderstorms will be possible in eastern Wyoming, southwest South Dakota, western Nebraska and northeast Colorado. These thunderstorms will be capable of producing large hail, dangerous straight line winds and isolated tornadoes. In addition, heavy rain will bring threats of flash flooding to western Nebraska and northwest Kansas.
Monsoonal moisture and daytime heating will trigger isolated showers and thunderstorms over the Desert Southwest, the southern Sierra Nevada, the southern Great Basin and the lower Intermountain West. Temperatures will be 10 to 15 degrees above normal across most areas west of the Plains. Heat advisories will stay in effect for central Nevada and parts of southern California.
