Weather Underground Forecast for Tuesday, May 28, 2013.
Expect wet and warm weather to return to parts of the East on Tuesday, while cool and showery weather conditions continue in portions of the West.
In the eastern half of the nation, unsettled weather will persist in portions of the Midwest through the Northeast and parts of the Mid-Atlantic as a warm front reaching across the Midwest extends into the Northeast and high pressure over the Eastern Seaboard moves into the western Atlantic Ocean. Throughout this transition, winds from the south will usher warm and humid conditions northward, allowing much of the East to experience warmer daytime highs through the mid-week. Moisture will also pool along and ahead of this warm front, triggering more light to moderate showers, areas of locally heavy rain, and thunderstorms from the Mid-Misssippi River Valley through the Ohio Valley and Great Lakes into portions of the Lower Northeast and the Upper Mid-Atlantic. Areas from the Mid-Mississippi Valley through the Ohio Valley and southern Great Lakes are at slight risk of severe thunderstorm development with large hail and damaging wind gusts.
Meanwhile, behind this activity, impulses from the West will continue across the Central U.S., maintaining chances of showers and thunderstorms across the Southern and Central Plains. These areas are at slight risk of severe thunderstorm development with large hail and possible isolated tornadoes.
Out West, showers and thunderstorms in the Pacific Northwest and parts of northern California will spread into portions of the Intermountain West and into the Northern Rockies as the cold trough of low pressure supporting this activity shifts eastward into the Great Basin. Expect chilly, below normal temperatures to continue for much of the West Coast States through the mid-week.
Temperatures in the Lower 48 states Monday have ranged from a morning low of 23 degrees at Mt. Washington, N.H. to a high of 100 degrees at Wink, Texas
